Stirling Air Conditioner for Compact Cooling  

Science Conference Proceedings (OSTI)

BEETIT Project: Infinia is developing a compact air conditioner that uses an unconventional high efficient Stirling cycle system (vs. conventional vapor compression systems) to produce cool air that is energy efficient and does not rely on polluting refrigerants. The Stirling cycle system is a type of air conditioning system that uses a motor with a piston to remove heat to the outside atmosphere using a gas refrigerant. To date, Stirling systems have been expensive and have not had the right kind of heat exchanger to help cool air efficiently. Infinia is using chip cooling technology from the computer industry to make improvements to the heat exchanger and improve system performance. Infinias air conditioner uses helium gas as refrigerant, an environmentally benign gas that does not react with other chemicals and does not burn. Infinias improvements to the Stirling cycle system will enable the cost-effective mass production of high-efficiency air conditioners that use no polluting refrigerants.

Air Conditioner Compressor Performance Model  

SciTech Connect

During the past three years, the Western Electricity Coordinating Council (WECC) Load Modeling Task Force (LMTF) has led the effort to develop the new modeling approach. As part of this effort, the Bonneville Power Administration (BPA), Southern California Edison (SCE), and Electric Power Research Institute (EPRI) Solutions tested 27 residential air-conditioning units to assess their response to delayed voltage recovery transients. After completing these tests, different modeling approaches were proposed, among them a performance modeling approach that proved to be one of the three favored for its simplicity and ability to recreate different SVR events satisfactorily. Funded by the California Energy Commission (CEC) under its load modeling project, researchers at Pacific Northwest National Laboratory (PNNL) led the follow-on task to analyze the motor testing data to derive the parameters needed to develop a performance models for the single-phase air-conditioning (SPAC) unit. To derive the performance model, PNNL researchers first used the motor voltage and frequency ramping test data to obtain the real (P) and reactive (Q) power versus voltage (V) and frequency (f) curves. Then, curve fitting was used to develop the P-V, Q-V, P-f, and Q-f relationships for motor running and stalling states. The resulting performance model ignores the dynamic response of the air-conditioning motor. Because the inertia of the air-conditioning motor is very small (H<0.05), the motor reaches from one steady state to another in a few cycles. So, the performance model is a fair representation of the motor behaviors in both running and stalling states.

Inverter control systems in the residential heat pump air conditioner  

SciTech Connect

A compressor capacity control with an inverter has been considered from the viewpoint of high energy saving in a refrigerating cycle. However, the system has not been put into practical use because of high initial cost, technical problems of electronic parts, and complexity of system control. In this connection, we developed the new inverter-controlled heat-pump air conditioner by using the latest electronics and refrigeration technology. This paper discusses the trend of energy saving in air conditioners in Japan and the objectives of developing the inverter controlled air conditioner. It also discusses the following items with respect to the inverter controlled air conditioner and the effects of employing an inverter: 1. Inverter for air conditioning; 2. Refrigeration cycle; 3. Air conditioner control with inverter.

Adsorption air conditioner for electric vehicle applications. Revision 1  

DOE Green Energy (OSTI)

This paper shows an analysis of the applicability of an adsorption system for electric vehicle (EV) air conditioning. Adsorption systems are designed and optimized to provide the required cooling for four combinations of vehicle characteristics and driving cycles. The resulting adsorption systems are compared with vapor compression air conditioners that can satisfy the cooling load. The objective function is the overall system weight, which includes the cooling system weight and the weight of the battery necessary to provide energy for air conditioner operation. The system with the minimum overall weight is considered to be the best, because a lower weight results in an increased vehicle range. The results indicate that, for the conditions analyzed in this paper, vapor compression air conditioners are superior to adsorption systems not only because they are lighter, but also because they have a higher COP and are more compact.

A conspicuous exception to this trend is commercialpackaged rooftop air conditioners, which have experiencedlittle to no efficiency improvement since 1992 when the Energy Policy Act of 1992 imposed federal minimum standards. Packaged rooftop units have been estimated to use on the order of76 billion kWh annually in the US, at a cost ofroughly $5.6 billion. Sales of these units are growing, and the majority of units sold have energy efficiency ratios (EERs) at orjust above the current national minimum efficiency standards. In this paper we document the static efficiencies ofcommercialpackaged air conditioners, explore the reasons behindthis efficiency gap, and assess opportunities for overcoming the barriers to efficiency improvements in these products.

Rooftop Unitary Air Conditioner with Integral Dedicated Outdoor Air System  

SciTech Connect

Energy use of rooftop and other unitary air-conditioners in commercial applications accounts for about 1 quad (10{sup 15} Btu) of primary energy use annually in the U.S. [Reference 7]. The realization that this cooling equipment accounts for the majority of commercial building cooled floorspace and the majority also of commercial building energy use has spurred development of improved-efficiency equipment as well as development of stricter standards addressing efficiency levels. Another key market driver affecting design of rooftop air-conditioning equipment has been concern regarding comfort and the control of humidity. Trends for increases in outdoor air ventilation rates in certain applications, and the increasing concern about indoor air quality problems associated with humidity levels and moisture in buildings points to a need for improved dehumidification capability in air-conditioning equipment of all types. In many cases addressing this issue exacerbates energy efficiency, and vice versa. The integrated dedicated outdoor air system configuration developed in this project addresses both energy and comfort/humidity issues.

Laboratory Performance Testing of Residential Window Air Conditioners  

SciTech Connect

Window air conditioners are the dominant cooling product for residences, in terms of annual unit sales. They are inexpensive, portable and can be installed by the owner. For this reason, they are an attractive solution for supplemental cooling, for retrofitting air conditioning into a home which lacks ductwork, and for renters. Window air conditioners for sale in the United States are required to meet very modest minimum efficiency standards. Four window air conditioners' performance were tested in the Advanced HVAC Systems Laboratory on NREL's campus in Golden, CO. In order to separate and study the refrigerant system's performance, the unit's internal leakage pathways, the unit's fanforced ventilation, and the leakage around the unit resulting from installation in a window, a series of tests were devised that focused on each aspect of the unit's performance. These tests were designed to develop a detailed performance map to determine whole-house performance in different climates. Even though the test regimen deviated thoroughly from the industry-standard ratings test, the results permit simple calculation of an estimated rating for both capacity and efficiency that would result from a standard ratings test. Using this calculation method, it was found that the three new air conditioners' measured performance was consistent with their ratings. This method also permits calculation of equivalent SEER for the test articles. Performance datasets were developed across a broad range of indoor and outdoor operating conditions, and used them to generate performance maps.

Monitoring and evaluation of replacing low-efficiency air conditioners with high-efficiency air conditioners in single-family detached houses in Austin, Texas  

SciTech Connect

The US DOE initiated this project to evaluate the performance of an air conditioner retrofit program in Austin, Texas. The City's Austin's Resource Management Department pursued this project to quantify the retrofit effect of replacing low-efficiency air conditioners with high-efficiency air conditioners in single-family detached homes. If successfully implemented, this retrofit program could help defer construction of a new power plant which is a major goal of this department. The project compares data collected from 12 houses during two cooling seasons under pre-retrofit and then post-retrofit air conditioner units. The existing low-efficiency air conditioners were monitored during the 1987 cooling season, replaced during the 1987--88 heating season with new, smaller sized, high-efficiency units, and then monitored again during the 1988 cooling season. Results indicated that the air conditioner retrofits reduce the annual air conditioner electric consumption and peak electric demand by an average of 38%. When normalized to the nominal capacity of the air conditioner, average demand savings were 1.12 W/ft{sup 2} and estimated annual energy savings were 1.419 kWh/ft{sup 2}. Individual air conditioner power requirements were found to be a well defined function of outdoor temperature as expected. In the absence of detailed data, estimates of the peak demand reductions of new air conditioners can be made from the manufacturer's specifications. Air conditioner energy consumption proved to be strongly linear as a function of the outdoor temperature as expected when taken as an aggregate. No noticeable differences in the diversity factor of the air conditioner usage were found. Analysis of the retrofit effect using PRISM yields estimates of the reduction in normalized annual consumption (NAC) and annual cooling consumption of 12% and 30%. 2 refs., 11 figs., 17 tabs.

Development and Analysis of Desiccant Enhanced Evaporative Air Conditioner Prototype  

SciTech Connect

This report documents the design of a desiccant enhanced evaporative air conditioner (DEVAP AC) prototype and the testing to prove its performance. Previous numerical modeling and building energy simulations indicate a DEVAP AC can save significant energy compared to a conventional vapor compression AC (Kozubal et al. 2011). The purposes of this research were to build DEVAP prototypes, test them to validate the numerical model, and identify potential commercialization barriers.

Determining benefits and costs of improved central air conditioner efficiencies  

SciTech Connect

Economic impacts on individual consumers from possible revisions to U.S. residential-type central air conditioner energy-efficiency standards are examined using a life-cycle cost (LCC) analysis. LCC is the consumer's cost of purchasing and installing a central air conditioner and operating it over its lifetime. This approach makes it possible to evaluate the economic impacts on individual consumers from the revised standards. The methodology allows an examination of groups of the population which benefit or lose from suggested efficiency standards. The results show that the economic benefits to consumers due to modest increases in efficiency are significant. For an efficiency increase of 20percent over the existing minimum standard (i.e., 12 SEER), 35percent of households with central air conditioners experience significant LCC savings, with an average savings of $453, while 25percent show significant LCC losses, with an average loss of $158 compared to apre-standard LCC average of $5,170. The remainder of the population (40percent) are largely unaffected.

The effects of galvanic corrosion on air conditioner performance  

E-Print Network (OSTI)

Corrosion of air conditioner outdoor heat exchangers (condensers) poses a significant problem for consumers living in coastal regions. This research sought to experimentally determine effects of galvanic corrosion on air conditioner condenser coils when subjected to high salt environments such as those found along the Gulf coast of the southern United States. The particular coil configuration investigated was comprised of copper tubing and aluminum fins, which form a galvanic couple in the presence of an electrolyte (salt water). Corrosion at the tube/fin junction results in a decrease of contact area through which heat is transferred. As a result, degradation of air conditioner performance occurs. An experimental plan was developed to operate two air conditioners for a period of approximately one year at a testing site in Galveston, Texas. Psychrometric evaluation of these units was conducted prior to exposure, at the midpoint of exposure, and at the conclusion of exposure. In addition, samples of copper and aluminum coils and coupons were subjected to the same coastal environment and investigated for corrosion attack. An accelerated corrosion test was also conducted to determine the effects of increased temperature, relative humidity, and salt concentrations on these samples. Air conditioner performance was measured during steady state cooling tests at outdoor conditions of 75?F (23.9?C), 82?F (27.8?C), 95?F (35.0?C), and 105?F (40.6?C) with an indoor temperature of 80?F (26.7?C) dry-bulb and 67?F (19.4?C) wet-bulb. Results of this testing showed that both units demonstrated average decreases in both cooling capacity and system EER. Sensible and latent capacity degradation for both package units showed decreases of approximately 4.6% and 20.9% respectively. System EER dropped over the course of the field investigation by 11.5% for one of the units and 8.3% for the other. An average corrosion rate for sample coupons subjected to the Galveston environment was calculated to be 0.13 MPY. Microscopic evaluation of aluminum from these galvanic couples after approximately one year of exposure showed an average pit depth approximately 19% of the aluminum thickness at the material interface. In comparison, aluminum fin collars at the material interface had an average pit about 22% of the thickness. Accelerated corrosion testing revealed some pitting, but not to the extent exhibited by field samples. A detailed description of the experimental setup, procedure, and results are provided.

An experimental energy recovering air-conditioner can produce fresh air exchange heat with exhaust air in the heat exchanger, which has no additional moving parts. The EER of the experimental air-conditioner (EAC) is increased by 17.4~37.3 percent over that of an ordinary window type air-conditioner (OAC), which is very significant for energy efficiency. On the other hand, the fresh air proportion of the EAC is increased by ~20 percent over that of the OAC, and the indoor noise of the EAC is decreased by ~3.8 dB. Therefore, indoor environment quality can be greatly improved with the EAC.

Influence of Air Conditioner Operation on Electricity Use and Peak Demand  

E-Print Network (OSTI)

Electricity demand due to occupant controlled room air conditioners in a large mater-metered apartment building is analyzed. Hourly data on the electric demand of the building and of individual air conditioners are used in analyses of annual and time-of-day peaks. Effects of occupant schedules and behavior are examined. We conclude that room air conditioners cause a sharp annual peak demand because occupants have strongly varying thresholds with respect to toleration of high indoor temperatures. However, time-or-day peaking is smoothed by air conditioning in this building due to significant off-peak operation of air conditioners by some occupants. If occupants were billed directly for electricity, off-peak use would probably diminish making the peaks more pronounced and exacerbating the utility company's load management problems. Future studies of this type in individually metered apartment buildings are recommended.

Cromer Cycle Air Conditioner: A Unique Air-Conditioner Desiccant Cycle to Enhance Dehumidification and Save Energy  

E-Print Network (OSTI)

The Cromer cycle uses a desiccant to move moisture from the saturated air leaving an air conditioning (AC) cooling coil to the air returning to the AC unit from the conditioned space. This has the thermodynamic effect of reducing the overall energy consumption of the AC unit and also has the side benefit of dramatically increasing the moisture removal capacity of the AC coil. Simulations, engineering analysis and laboratory tests have confirmed the technical feasibility of the thermodynamics of the cycle. This work reports on a test at ARI conditions (95 deg. F outside, 80 deg F, 51% RH inside). The test unit (10 year old, 5 ton Bryant Air Conditioner) without the Cromer cycle, averaged an EER of 7.93 at a latent ratio of 26.2 % (SHR = 0.738). With the Cromer cycle added, the same unit averaged a total cooling EER of 11.82 with a water removal latent ratio of 53.4% (SHR= 0.466). The measured 16.4% reduction in energy use and 47.9 improvement in EER is significant for the tests at the 95% confidence level. This technology represents a major improvement in energy performance for the control of humidity conditions.

Effect of Return Air Leakage on Air Conditioner Performance in Hot/Humid Climates  

E-Print Network (OSTI)

An experimental study was conducted to quantify the effect of return air leakage from hot/humid attic spaces on the performance of a residential air conditioner. Tests were conducted in psychrometric facilities where temperatures and humidities could be controlled closely. Return air leakage from hot attic spaces was simulated by assuming adiabatic mixing of the indoor air at normal conditions with the attic air at high temperatures. Effective capacity and Energy Efficiency Ratio both decreased with increased return air leakage. However, power consumption was relatively constant for all variables except outdoor temperature, which meant that for the same power consumption, the unit delivered much lower performance when there was return air leakage. The increase in sensible heat ratio (SHR) with increasing leakage showed one of the most detrimental effects of return air leakage on performance.

Analysis and optimization of an adsorption air conditioner for electric vehicle applications  

SciTech Connect

This paper shows an analysis of the applicability of an adsorption system for electric vehicle (EV) air conditioning. Adsorption systems are designed and optimized to provide the required cooling for four combinations of vehicle characteristics and driving cycles. The resulting adsorption systems are compared with vapor compression air conditioners that can satisfy the cooling load. The objective function is the overall system weight, which includes the cooling system weight and the weight of the battery necessary to provide energy for air conditioner operation. The system with the minimum overall weight is considered to be the best. The results show the optimum values of all the variables, as well as temperatures and amounts adsorbed, for the adsorption and desorption processes. The results indicate that, for the conditions analyzed in this paper, vapor compression air conditioners are superior to adsorption systems, not only because they are lighter, but also because they have a higher COP and are more compact.

The Effect of Reduced Evaporator Air Flow on the Performance of a Residential Central Air Conditioner  

E-Print Network (OSTI)

This paper discusses the measured degradation in performance of a residential air conditioning system operating under reduced evaporator air flow. Experiments were conducted using a R-22 three-ton split-type cooling system with a short-tube orifice expansion device. Results are presented here for a series of tests in which the evaporator air flow was reduced from 25 to 90% below what is normally recommended for this air conditioner. At present, very little information is available which quantifies the performance of a residential cooling system operating under degraded conditions such as reduced evaporator air flow. Degraded performance measurements can provide information which could help electric utilities evaluate the potential impact of system-wide maintenance programs.

Swozzle based burner tube premixer including inlet air conditioner for low emissions combustion  

DOE Patents (OSTI)

A burner for use in a combustion system of a heavy-duty industrial gas turbine includes a fuel/air premixer having an air inlet, a fuel inlet, and an annular mixing passage. The fuel/air premixer mixes fuel and air into a uniform mixture for injection into a combustor reaction zone. The burner also includes an inlet flow conditioner disposed at the air inlet of the fuel/air premixer for controlling a radial and circumferential distribution of incoming air. The pattern of perforations in the inlet flow conditioner is designed such that a uniform air flow distribution is produced at the swirler inlet annulus in both the radial and circumference directions. The premixer includes a swozzle assembly having a series of preferably air foil shaped turning vanes that impart swirl to the airflow entering via the inlet flow conditioner. Each air foil contains internal fuel flow passages that introduce natural gas fuel into the air stream via fuel metering holes that pass through the walls of the air foil shaped turning vanes. By injecting fuel in this manner, an aerodynamically clean flow field is maintained throughout the premixer. By injecting fuel via two separate passages, the fuel/air mixture strength distribution can be controlled in the radial direction to obtain optimum radial concentration profiles for control of emissions, lean blow outs, and combustion driven dynamic pressure activity as machine and combustor load are varied.

Measuring Short-term Air Conditioner Demand Reductions for Operations and Measuring Short-term Air Conditioner Demand Reductions for Operations and Settlement Title Measuring Short-term Air Conditioner Demand Reductions for Operations and Settlement Publication Type Report LBNL Report Number LBNL-5330E Year of Publication 2012 Authors Bode, Josh, Michael J. Sullivan, and Joseph H. Eto Pagination 120 Date Published 01/2012 Publisher LBNL City Berkeley Keywords consortium for electric reliability technology solutions (certs), electricity markets and policy group, energy analysis and environmental impacts department Abstract Several recent demonstrations and pilots have shown that air conditioner (AC) electric loads can be controlled during the summer cooling season to provide ancillary services and improve the stability and reliability of the electricity grid. A key issue for integration of air conditioner load control into grid operations is how to accurately measure shorter-term (e.g., ten's of minutes to a couple of hours) demand reductions from AC load curtailments for operations and settlement. This report presents a framework for assessing the accuracy of shorter-term AC load control demand reduction measurements. It also compares the accuracy of various alternatives for measuring AC reductions - including methods that rely on regression analysis, load matching and control groups - using feeder data, household data and AC end-use data. A practical approach is recommended for settlement that relies on set of tables, updated annually, with pre-calculated load reduction estimates. The tables allow users to look up the demand reduction per device based on the daily maximum temperature, geographic region and hour of day and simplify the settlement process.

The Impact of Residential Air Conditioner Charging and Sizing on Peak Electrical Demand  

E-Print Network (OSTI)

Electric utilities have had a number of air conditioner rebate and maintenance programs for many years. The purpose of these programs was to improve the efficiency of the stock of air conditioning equipment and provide better demand-side management. This paper examines the effect of refrigerant charging (proper servicing of the equipment), system sizing, and efficiency on the steady-state, coincident peak utility demand of a residential central air conditioning system. The study is based on the results of laboratory tests of a three-ton, capillary tube expansion, split-system air conditioner, system capacity and efficiency data available from manufacturer's literature, and assumptions about relative sizing of the equipment to cooling load on a residence. A qualitative discussion is provided concerning the possible impacts of transient operation and total energy use on utility program decisions. The analysis indicates that proper sizing of the unit is the largest factor affecting energy demand of the three factors (sizing, charging, and efficiency) studied in this paper. For typical oversizing of units to cooling loads in houses, both overcharging and undercharging showed significant negative impact on peak demand. The impacts of SEER changes in utility peak demand were found to be virtually independent of oversizing. For properly sized units, there was a small peak benefit to higher efficiency air conditioners.

Techno-Economic Analysis of Indian Draft Standard Levels for RoomAir Conditioners  

SciTech Connect

The Indian Bureau of Energy Efficiency (BEE) finalized its first set of efficiency standards and labels for room air conditioners in July of 2006. These regulations followed soon after the publication of levels for frost-free refrigerators in the same year. As in the case of refrigerators, the air conditioner program introduces Minimum Efficiency Performance Standards (MEPS) and comparative labels simultaneously, with levels for one to five stars. Also like the refrigerator program, BEE defined several successive program phases of increasing stringency. In support of BEE's refrigerator program, Lawrence Berkeley National Laboratory (LBNL) produced an analysis of national impacts of standards in collaboration with the Collaborative Labeling and Standards Program (CLASP). That analysis drew on LBNL's experience with standards programs in the United States, as well as many other countries. Subsequently, as part of the process for setting optimal levels for air conditioner regulations, CLASP commissioned LBNL to provide support to BEE in the form of a techno-economic evaluation of air conditioner efficiency technologies. This report describes the methodology and results of this techno-economic evaluation. The analysis consists of three components: (1) Cost effectiveness to consumers of efficiency technologies relative to current baseline. (2) Impacts on the current market from efficiency regulations. (3) National energy and financial impacts. The analysis relied on detailed and up-to-date technical data made available by BEE and industry representatives. Technical parameters were used in conjunction with knowledge about air conditioner use patterns in the residential and commercial sectors, and prevailing marginal electricity prices, in order to give an estimate of per-unit financial impacts. In addition, the overall impact of the program was evaluated by combining unit savings with market forecasts in order to yield national impacts. LBNL presented preliminary results of these analyses in May 2006, at a meeting of BEEs Technical Committee for Air Conditioners. This meeting was attended by a wide array of stakeholder, including industry representatives, engineers and consumer advocates. Comments made by stakeholders at this meeting are incorporated into the final analysis presented in this report. The current analysis begins with the Rating Plan drafted by BEE in 2006, along with an evaluation of the market baseline according to test data submitted by manufacturers. MEPS, label rating levels, and baseline efficiencies are presented in Section 2. First, we compare Indian MEPS with current standards in other countries, and assess their relative stringency. Baseline efficiencies are then used to estimate the fraction of models likely to remain on the market at each phase of the program, and the impact on market-weighted efficiency levels. Section 3 deals with cost-effectiveness of higher efficiency design options. The cost-benefit analysis is grounded in technical parameters provided by industry representatives in India. This data allows for an assessment of financial costs and benefits to consumers as a result of the standards and labeling program. A Life-Cycle Cost (LCC) calculation is used to evaluate the impacts of the program at the unit level, thus providing some insight into the appropriateness of the levels chosen, and additional opportunities for further ratcheting. In addition to LCC, we also calculate payback periods, cost of conserved energy (CCE), and return on investment (ROI). Finally, Section 4 covers national impacts. This is an extension of unit level estimates in the two previous sections. Extrapolation to the national level depends on a forecast of air conditioner purchases (shipments), which we describe here. Following the cost-benefit analysis, we construct several efficiency scenarios including the BEE plan, but also considering further potential for efficiency improvement. These are combined with shipments through a stock accounting model in order to forecast air conditioner energy consumption

13 SEER Standard for Central Air Conditioners and Heat Pumps (released in AEO2005)  

Reports and Publications (EIA)

In January 2004, after years of litigation in a case that pitted environmental groups and Attorneys General from 10 States against the U.S. Secretary of Energy, the U.S. Court of Appeals for the Second Circuit reestablished the central air conditioner and heat pump standard originally set in January 2001 [3]. The Courts ruling, which struck down a May 2002 rollback of the 2001 standard to a 12 SEER, mandates that all new central air conditioners and heat pumps meet a 13 SEER standard by January 2006, requiring a 30-percent increase in efficiency relative to current law. The AEO2005 reference case incorporates the 13 SEER standard as mandated by the Courts ruling.

E-Print Network (OSTI)

With the upcoming ban on the production of R-22 in 2010, residential air-conditioning equipment will need to be redesigned with a more environmentally benign working fluid. R-410a is a strong candidate for replacing R-22. A model of an air-conditioning system with a focus on the finned-tube condenser design details using R-410a as the working fluid is developed. An optimization algorithm is implemented to find the optimal condenser design with various constraints for an efficiency figure of merit. The software developed is appropriate for engineering design use in the air-conditioning industry.

Energy Consumption Estimation for Room Air-conditioners Using Room Temperature Simulation with One-Minute Intervals  

E-Print Network (OSTI)

For the purpose of developing optimized control algorithm for room air-conditioners to ensure their energy efficiency, a short time interval (i.e., one minute) simulation of building thermal performance is necessary because the sampling time interval for room air-conditioner control is one minute in general. This paper studies the short-time interval room air temperature simulation method using the response factor method. Using the simulated room air temperature, an air-conditioner's running time can be known so that its energy consumption can be estimated accurately. In order to verify the simulation accuracy, an actual room equipped with a gas-engine heat pump (GHP) air-conditioning system is studied by both simulation and measurement. The cooling amount produced by the GHP is calculated using measured refrigerant pressure and temperature at condenser and evaporator respectively. The Root Mean Square Error (RMSE) between measured cooling amount and simulated cooling load is 18.9 percent of the average measured value. The profile of simulated room air temperature in both air-conditioned daytime and nighttime without air-conditioning can match the measured room air temperature. With respect to the estimated energy consumption, the profile of simulated energy consumption can match the measured data. The simulation accuracy of room air temperature and energy consumption during the air-conditioner start-up period is not good and needs to be improved in future research. But in general, the verification shows that this energy consumption simulation method is acceptable for evaluating the energy performance of a room air-conditioner, and can also be a useful tool for commissioning room air-conditioners.

E-Print Network (OSTI)

This paper presents the results of a preliminary investigation at The University of Texas at Austin of alternative liquid desiccants for use in a hybrid desiccant air-conditioning system in which a desiccant is circulated between the evaporator and the condenser of a vapor-compression air conditioner. The liquid desiccants studied were lithium chloride, lithium bromide, calcium chloride, and triethylene glycol. Each candidate desiccant was subjected to a screening process which weighed the merits of the desiccant in terms of selected characteristics. The best liquid desiccant for the anticipated application was found to be calcium chloride.

A conceptual development program with the ultimate objective of substantially reducing or eliminating the parasitic power requirement for liquid sorbent air conditioning systems is described. Operational tests conducted on small prototypes have shown that some of the pumps can be replaced with other apparatus requiring no electrical energy. Experimental work has also shown that some electric utility dependent pumps might be replaced by solar powered pumps thus making the system more passive in nature.

SciTech Connect

A 3.3-ton military air conditioning unit has been studied experimentally in both baseline (as received) and as modified for liquid over-feeding (LOF) operation. Tne baseline test, using a proper refrigerant charge, showed the measured cooling capacity to be less than 1% off the rated capacity at 95{degrees}F ambient temperature. The test results indicate that LOF operation outperforms the baseline case over a wide ambient temperature range in terms of cooling capacity, power consumption, and system coefficient of performance (COP). At a 95{degrees}F test point, LOF operation has a cooling capacity of 51,100 BTU per hour, which is a 28.9% improvement over the baseline operation capacity of 39,600 BTU per hour. The COP for LOF at 95{degrees}F is 2.62, which is 29% better than the baseline COP of 2.03. However, an optimal refrigerant charge is essential for LOF to work properly.

Effects of Air Conditioner Use on Real-World Fuel Economy  

Science Conference Proceedings (OSTI)

Vehicle data were acquired on-road and on a chassis dynamometer to assess fuel consumption under several steady cruise conditions and at idle. Data were gathered for various air conditioner (A/C) settings and with the A/C off and the windows open. Two vehicles were used in the comparisonstudy: a 2009 Ford Explorer and a 2009 Toyota Corolla. At steady speeds between 64.4 and 112.7 kph (40 and 70 mph), both vehicles consumed more fuel with the A/C on at maximum cooling load (compressor at 100% duty cycle) than when driving with the windows down. The Explorer maintained this trend beyond 112.7 kph (70 mph), while the Corolla fuel consumption with the windows down matched that of running the A/C at 120.7 kph (75 mph), and exceeded it at 128.7 kph (80 mph). The largest incremental fuel consumption rate penalty due to air conditioner use occurred was nearly constant with a weakslight trend of increasing consumption with increasing compressor (and vehicle) speed. Lower consumption is seenobserved at idle for both vehicles, likely due to the low compressor speed at this operating point

Energy savings and economics of advanced control strategies for packaged air conditioners with gas heat  

Science Conference Proceedings (OSTI)

This paper presents an evaluation of the potential energy savings from adding advanced control to existing packaged air conditioners. Advanced control options include air-side economizer, multi-speed fan control, demand control ventilation and staged cooling. The energy and cost savings from the different control strategies individually and in combination are estimated using the EnergyPlus detailed energy simulation program for four building types, namely, a small office building, a stand-alone retail building, a strip mall building and a supermarket building. For each of the four building types, the simulation was run for 16 locations covering all 15 climate zones in the U.S. The maximum installed cost of a replacement controller that provides acceptable payback periods to owners is estimated.

Investigations on Vapour Compression Air Conditioner with Direct Contact Desiccant Loop over Condenser and Evaporator  

E-Print Network (OSTI)

Perceived air quality increases when relative humidity is decreased till about 30% in the range of comfort temperature. In the present scenario, humidity is considered as a pollutant. Hence, a controlled environment not only at low temperature but also at low humidity is desired for many applications such as archives, data centers, etc. Either a separate dehumidifier or a precision air conditioning (AC) system needs to be employed for such an application. In fact, the latter forms a reheat AC system which happens to be energy inefficient. In view of this, a vapor compression window air conditioner is investigated with a superimposed liquid desiccant loop harnessing the advantages of both the compression system (high COP) and desiccant system (low humidity). Operation of such a novel system is explained, elucidating the operational feasibility. The results presented consider the characteristics of such a system with respect to changes in the evaporator inlet air temperature and humidity. The change in the specific humidity of air is compared for vapor compression system and the direct contact hybrid system for different values of inlet air temperature.

Modeling of a second-generation solar-driven Rankine air conditioner. Final report  

DOE Green Energy (OSTI)

Ten configurations of a second-generation (2G), solar-powered, Rankine-driven air conditioner were simulated and the data presented for use in companion studies. The results of the analysis show that the boiling-in-collector (BIC) configuration generates more power per collector area than the other configurations. The models used to simulate the configuration are presented in this report. The generated data are also presented. Experimental work was done under this study to both improve a novel refrigerant and oil lubrication system for the centrifugal compressor and investigate the aerodynamic unloading characteristics of the centrifugal compressor. The information generated was used to define possible turbo-gearbox configurations for use in the second generation computer simulation.

Life-cycle cost and payback period analysis for commercial unitary air conditioners  

SciTech Connect

This report describes an analysis of the economic impacts of possible energy efficiency standards for commercial unitary air conditioners and heat pumps on individual customers in terms of two metrics: life-cycle cost (LCC) and payback period (PBP). For each of the two equipment classes considered, the 11.5 EER provides the largest mean LCC savings. The results show how the savings vary among customers facing different electricity prices and other conditions. At 11.5 EER, at least 80% of the users achieve a positive LCC savings. At 12.0 EER, the maximum efficiency analyzed, mean LCC savings are lower but still positive. For the {ge} $65,000 Btu/h to <135,000 Btu/h equipment class, 59% of users achieve a positive LCC savings. For the $135,000 Btu/h to <240,000 Btu/h equipment class, 91% of users achieve a positive LCC savings.

Procuring High-Efficiency Air Conditioners: Harnessing Competition to Achieve Advances in Technology  

SciTech Connect

The Departments of Energy and Defense have joined forces to devise an innovative approach to acquiring more efficient unitary air conditioners that minimize life-cycle cost through improved technology. The resulting procurement solicitation challenges manufacturers to offer products with reduced life-cycle cost, taking into account both the initial prices of their units and the costs of their ongoing electric consumption. Competing products are evaluated according to a formula that reflects both full- and part-load efficiencies under a simulated set of time-varying climate conditions. The authors will report on the progress of the procurement, including the choice of target product based on market prospects and technology readiness, development of the technical specifications and electric consumption simulator, approaches to administrative and procedural challenges, responses from manufacturers, and plans for product promotion in the future.

Modeling the effects of Refrigerant Charging on Air Conditioner Performance Characteristics For Three Expansion Devices  

E-Print Network (OSTI)

An experimental and analytical study concerned with the off-design refrigerant charging of air conditioners is presented. A series of experiments were conducted to characterize the effects of refrigerant charge and type of expansion device on the system performance (capacity, EER, SEER, etc.) of an air conditioner. All experiments were performed according to the ASHRAE Standard [1983]. The effects of off-design refrigerant charge in the system, type of expansion device (capillary tube, TXV, and short-tube orifice), and outdoor dry-bulb temperature (82 to l00F) on the wet and dry steady state and cyclic tests are addressed in this study. The fully charged condition was established as a base case for all the expansion device systems. A full charge was obtained by charging the unit to the superheat or subcooled condition specified by the manufacturer charging chan. Once the full charge was determined, refrigerant was then added in 5% increments from -20% of full charge to +20% of full charge to cover the full range of charging conditions for a particular expansion device being tested. The investigation of off-design charging indicated that the system performance variables (total capacity, EER, and SEER) of the unit with capillary tube were more sensitive to off-design charging than the systems with TXV and short-tube orifice. From -20% to +20% charging, the capacity and EER showed a strong dependence on the outdoor temperature, but varied little with charge for the TXV and short-tube orifice expansion systems. A -20% charging resulted in a 21% reduction in SEER while a +20% charging produced an 11% reduction in SEER for the unit with capillary tube. For the TXV, SEER dropped 2% and 8% for -20% and +20% refrigerant charging, respectively. The SEER was constant at 9.4 for all the charging condition except for -5% charging where it peaked to 9.9 for the short-tube orifice expansion system. This trend would suggest that the range of sensitivity of a short-tube orifice system is confined within a small refrigerant charge. A new heat exchanger model based on tube-by-tube simulation was developed and integrated into the ORNL heat pump model. The model was capable of simulating the steady state response of a vapor compression air-to-air heat pump and air conditioner commonly used in residential applications. The simulated results were compared with laboratory tests at two outdoor temperatures. It was found that the ORNL model estimates were within an average of 3% of the experimental results from - 10% to +10% charging conditions. The model predicted the system performance up to 8% higher than measured results at +/-20% and +/-15% charging conditions. Among the eight void fraction models studied, the Hughmark model showed the best agreement between superheat and subcooled temperatures, refrigerant flow rate and capacity and the measured results.

Consumer life-cycle cost impacts of energy-efficiency standards for residential-type central air conditioners and heat pumps  

SciTech Connect

In support of the federal government's efforts to raise the minimum energy-efficiency standards for residential-type central air conditioners and heat pumps, a consumer life-cycle cost (LCC) analysis was conducted to demonstrate the economic impacts on individual consumers from revisions to the standards. LCC is the consumer's cost of purchasing and installing an air conditioner or heat pump and operating the unit over its lifetime. The LCC analysis is conducted on a nationally representative sample of air conditioner and heat pump consumers resulting in a distribution of LCC impacts showing the percentage of consumers that are either benefiting or being burdened by increased standards. Relative to the existing minimum efficiency standard of 10 SEER, the results show that a majority of split system air conditioner and heat pump consumers will either benefit or be insignificantly impacted by increased efficiency standards of up to 13 SEER.

Progress towards Managing Residential Electricity Demand: Impacts of Standards and Labeling for Refrigerators and Air Conditioners in India  

SciTech Connect

The development of Energy Efficiency Standards and Labeling (EES&L) began in earnest in India in 2001 with the Energy Conservation Act and the establishment of the Indian Bureau of Energy Efficiency (BEE). The first main residential appliance to be targeted was refrigerators, soon to be followed by room air conditioners. Both of these appliances are of critical importance to India's residential electricity demand. About 15percent of Indian households own a refrigerator, and sales total about 4 million per year, but are growing. At the same time, the Indian refrigerator market has seen a strong trend towards larger and more consumptive frost-free units. Room air conditioners in India have traditionally been sold to commercial sector customers, but an increasing number are going to the residential sector. Room air conditioner sales growth in India peaked in the last few years at 20percent per year. In this paper, we perform an engineering-based analysis using data specific to Indian appliances. We evaluate costs and benefits to residential and commercial sector consumers from increased equipment costs and utility bill savings. The analysis finds that, while the BEE scheme presents net benefits to consumers, there remain opportunities for efficiency improvement that would optimize consumer benefits, according to Life Cycle Cost analysis. Due to the large and growing market for refrigerators and air conditioners in India, we forecast large impacts from the standards and labeling program as scheduled. By 2030, this program, if fully implemented would reduce Indian residential electricity consumption by 55 TWh. Overall savings through 2030 totals 385 TWh. Finally, while efficiency levels have been set for several years for refrigerators, labels and MEPS for these products remain voluntary. We therefore consider the negative impact of this delay of implementation to energy and financial savings achievable by 2030.

Modeled and measured effects of compressor downsizing in an existing air conditioner/heat pump in the cooling mode  

SciTech Connect

It is not uncommon to find oversized central air conditioners in residences. HVAC contractors sometimes oversize central air conditioners for one reason or another--some to the point that they may be 100% larger than needed to meet the load. Retrofit measures done to improve house envelope and distribution system efficiency also contribute to HVAC oversizing, as they reduce house heating and cooling loads. Proper sizing of an air conditioner or heat pump allows more efficient operation and provides a more comfortable environment than a highly oversized unit. Another factor that lowers operating efficiency is an improper refrigerant charge. Field inspections have revealed that about half of the units checked were not properly charged. An option available to homeowners with oversized air conditioners is to replace the existing compressor with a smaller, more efficient compressor, rather than purchasing a new, smaller unit. Such a retrofit may be economically justified, especially during a compressor failure, provided the oversizing of the existing unit is not too great. A used, 15-year old, single-package heat pump with a capillary tube expansion device on the indoor coil was purchased and tested in a set of environmental chambers to determine its cooling performance at various conditions. The system was also modeled to estimate its existing performance, and that with two different types of retrofitted state-of-the-art (SOA) efficient compressors with about 30% less capacity than the original compressor. This reduced the overall system cooling capacity by about 25%. Modeling estimated that the retrofit would increase system EER at 95 F by 30%, SEER by 34%, and reduce power demand by 39% compared to the existing unit. Reduced cycling losses account for the higher increase in SEER.

The System Impact of Air-Conditioner Under-voltage Protection Schemes  

Science Conference Proceedings (OSTI)

This paper presents simulation results of evaluating an under-voltage protection scheme designed to take stalled air-conditioner (a/c) units offline such that the slow voltage recovery phenomena can be solved on areas heavily loaded with a/c motors during summer peak periods. A three feeder test-bed has been first used to quantify the effectiveness of the protection scheme and the sensitivity of the under-voltage relay settings. Then two real system events of the Western US power grid have been studied to evaluate the area impact of the protection scheme proposed by Southern California Edison. The study demonstrates that by taking all or most of the stalled a/c unit offline, the feeder voltage will recover in a few seconds, much quicker than the tens of seconds that the standard thermal relays imbedded in the motors need to trip the units. The drawback of the control scheme is that after the voltage recover, it settled at a higher voltage than before the faults because a large chuck of load has been shed.

Performance of an experimental solar-driven absorption air conditioner. Annual report, July 1975--September 1976  

DOE Green Energy (OSTI)

An important pathway for the use of solar energy for space conditioning of buildings is the development of a heat-actuated air conditioner that can operate with the temperatures available from flat-plate solar collectors and use air cooling for disposal of the waste heat. The solar heating and cooling program of the Lawrence Berkeley Laboratory is exploring the use of the ammonia-water absorption cycle for this purpose. Results of the initial tests of an experimental system that has been fabricated to provide basic engineering data on the operation of the ammonia-water absorption cycle under such conditions are presented. A nominal three-ton, continuous operation, heat-actuated water chiller has been fabricated by drastic modification of a commercial gas-fired unit. The major modifications included designing a new water-heated generator, adding a preheater to the solution circuit, and increasing the flow rate of solution by a factor of about three. The unit was instrumented for measurement of temperatures, pressures, and solution concentrations at points in the circuit. Twenty-two experimental runs have been made and the results analyzed. An analysis of the thermodynamic cycle which includes the finite effectiveness of heat transfer at various points in the cycle is shown to predict with good accuracy the measured values of COP. The measured coefficient of performance agreed with the calculated values over the range 0.4 to 0.75 as the conditions of individual runs were varied. The agreement with the calculated values was within about 5 percent.

The Oklahoma Field Test: Air-conditioning electricity savings from standard energy conservation measures, radiant barriers, and high-efficiency window air conditioners  

SciTech Connect

A field test Involving 104 houses was performed in Tulsa, Oklahoma, to measure the air-conditioning electricity consumption of low-income houses equipped with window air conditioners, the reduction in this electricity consumption attributed to the installation of energy conservation measures (ECMS) as typically installed under the Oklahoma Weatherization Assistance Program (WAP), and the reduction achieved by the replacement of low-efficiency window air conditioners with high-efficiency units and the installation of attic radiant barriers. Air-conditioning electricity consumption and indoor temperature were monitored weekly during the pre-weatherization period (June to September 1988) and post-weatherization period (May to September 1989). House energy consumption models and regression analyses were used to normalize the air-conditioning electricity savings to average outdoor temperature conditions and the pre-weatherization indoor temperature of each house. The following conclusions were drawn from the study: (1) programs directed at reducing air-conditioning electricity consumption should be targeted at clients with high consumption to improve cost effectiveness; (2) replacing low-efficiency air conditioners with high-efficiency units should be considered an option in a weatherization program directed at reducing air-conditioning electricity consumption; (3) ECMs currently being installed under the Oklahoma WAP (chosen based on effectiveness at reducing space-heating energy consumption) should continue to be justified based on their space-heating energy savings potential only; and (4) attic radiant barriers should not be included in the Oklahoma WAP if alternatives with verified savings are available or until further testing demonstrates energy savings or other benefits in this typo of housing.

Experimental analysis of a window air conditioner with a R-22 and R32/R125/R134a mixture  

SciTech Connect

Much experimental and theoretical analysis of potential R-22 replacements has been accomplished. However, published information about the experimental analysis of any off-the-shelf air conditioner with a potential R-22 replacement at realistic, operating conditions is still rare. This type of work could be useful because it provides baseline data for comparing the performance of R-22 and its potential replacement at drop-in conditions. In this study, an off-the-shelf window air conditioner was tested at Air Conditioning and Refrigeration Institute (ARI)-rated indoor conditions and at different ambient temperatures, including the ARI-rated outdoor condition, with R-22 and with its potential replacement, a ternary mixture of R-32(30%)/R-125(10%)/R-134a(60%) (the ternary mixture). A test rig was built that provided for baseline operation and for the option of operating the system with a flooded evaporator by means of liquid over-feeding (LOF). The test results indicated the cooling capacity of the ternary mixture was 7.7% less than that of R-22 at 95{degrees}F ambient for baseline operation. The cooling capacity for both refrigerants improved when a flooded evaporator, or LOF, was used. For LOF operation, the cooling capacity of the ternary mixture was only 1.1% less than that of R-22. The ternary mixture had slightly higher compressor discharge pressure, a lower compressor discharge temperature, slightly lower compressor power consumption, and a higher compressor high/low pressure ratio.

Analysis and design of a solar-powered liquid-desiccant air conditioner for use in hot and humid climates  

SciTech Connect

An experimental and theoretical investigation of the feasibility of a solar-powered liquid-desiccant air conditioner, for use in hot and humid climates, was carried out at the Mechanical Engineering Department, University of Florida. The proposed liquid desiccant system used nonadiabatic contactors, packed with finned-tube coils, for both moist air dehumidification and liquid-desiccant regeneration. A theoretical model was developed to analyze the complex phenomena of simultaneous heat and mass transfer in nonadiabatic contactors, as well as the continuous interaction between the dehumidification and regeneration processes. A computer code was written to assist in the analysis of the dehumidification and regeneration processes separately and coupled, for continuous operation. It was used to investigate the interaction between the different controlling parameters and their effects on the overall performance of the desiccant system. A fully solar-powered liquid-desiccant air-conditioner, with three tons of capacity was designed and optimized including economical criteria. The overall coefficient of performance (COP) of the optimized system was determined to be 0.312.

Retrofitting an automotive air conditioner with HFC-134a, additive, and mineral oil. Final report, October 1992-May 1994  

Science Conference Proceedings (OSTI)

The paper gives results of an evaluation of a lubricant additive developed for use in retrofitting motor vehicle air conditioners. The additive was designed to enable HFC-134a to be used as a retrofit refrigerant with the existing mineral oil in CFC-12 systems. The goal of the project was to provide preliminary feasibility testing of the additive. The cooling effect of the test system retrofitted with HFC-134a and the oil additive was nearly the same as that of the original system with CFC 12 refrigerant. If lubricant additives prove to be successful, miscible lubricants may not be needed for retrofitting some automotive systems. The retrofitting procedure might be simplified and the cost to consumers might be reduced. It has not been determined if retrofitting systems with HFC-134a and oil additives is feasible for a wider range of operating conditions and types of equipment, including the applicability of orifice tube/suction accumulator systems.

A cost-effective and fuel-conserving nonelectric air conditioner that combines engine-driven compression and absorption cycles  

SciTech Connect

A natural-gas-fueled electricity-producing condensing furnace with the potential of being mass produced at a cost of less than $1000 and providing a cost-effective and highly fuel-conserving alternative to virtually every residential gas furnace in the world has been developed. While this is a new system, it completely consists of existing mass-produced components including single-cylinder air-cooled engines, induction motors/generators, and control devices. Thus, timely commercialization can be expected and an important new energy technology and industry can result. However, all the benefits of this electricity-producing furnace occur during the winter. This has stimulated the search for a new system that can provide comparable benefits in terms of fuel conservation, the environment, and electric utility peak reduction during the summer, along with the prospects of a new and efficient new use for the natural gas surpluses that occur during the summer. The resulting system, which can use existing component equipment, is a commercial-size nonelectric air conditioner that consists of an automobile-type engine converted to natural gas, or possibly a diesel or combustion turbine, driving a Freon compression cycle, with virtually all of the engine reject heat from the exhaust and from the engine cooling system driving a conventional absorption air conditioning cycle.

The Influence of Operating Modes, Room Temperature Set Point and Curtain Styles on Energy Consumption of Room Air Conditioner  

E-Print Network (OSTI)

A field investigation was carried out in an office building of Changsha city in winter and summer, the influence of different running modes, curtain styles and room temperature set point on energy consumption of room air conditioner (RAC) was studied. The results show that: In summer automatic speed mode consumes the least refrigerating energy in different running modes, compared with low speed and high speed modes, it can conserve energy for 27.3% and 15.8%, respectively. In the same running mode, setting outer curtain can conserve energy for 40.9% and 20.4% compared with no curtain and inner curtain states, respectively. In winter high speed mode is the most efficient for saving energy which can decrease 40.3% and 30.9% compared with low speed and automatic speed modes. In the same running mode, setting inner curtain state makes the least heating energy consumption in cloudy day, about 10.8% and 2.7% less than no curtain and outer curtain states. However, it is not obvious when the day is fine. The heating energy consumption decreases as room temperature set point falls, compared with the energy consumption at 20.5 C and 19.5 C, it is decreases for 34.1% and17.0 % at 18.5 C, respectively. All the results will be the reference of environment design and control for air conditioning room.

An Evaluation of Improper Refrigerant Charge on the Performance of a Split System Air Conditioner with a Thermal Expansion Valve  

E-Print Network (OSTI)

The effect of the improper charging on steady state and cyclic performance (capacity, EER, power consumption, SEER, and coefficient of degradation) of a residential air conditioner which utilized a thermal expansion valve was investigated. This study was the continuation of ESL/CON/88-1 performed by Mohsen Farzad and Dennis O'Neal. A fully charged condition was established as a base case. The full charge was obtained by charging the unit to the subcooling specified by the manufacturer for a specific indoor and outdoor temperatures. Once the full charge was determined, the unit was subjected to 40%, 30%, 20%, 15%, 10%, and 5% undercharging and 5%, 10%, 15%, and 20% overcharging of refrigerant by mass. The fully charged tests were compared to those for under and overcharging. The performance of the unit was evaluated as a function of charge as well as at four outdoor room temperatures (82F, 90F, 95F, and 100F). As the outdoor temperature increased, the total capacity and EER dropped. The maximum total capacity, EER, and SEER were found at 10% undercharging (12 6 oz). The capacity and efficiency (EER and SEER) of the unit were found to be less sensitive to under/overcharging than the unit with a capillary tube expansion previously studied. Other data such as refrigerant flow rate, sensible heat ratio, superheat and subcooling were also presented.

An Evaluation of Improper Refrigerant Charge on the Performance of a Split System Air Conditioner with Capillary Tube Expansion  

E-Print Network (OSTI)

The effect of the improper charging on the performance (capacity, EER, power consumption, SEER, and coefficient of degradation) of a residential air conditioner during the steady state (wet and dry coils) and cycling operation was investigated. The fully charged condition was established as a base case. A full charge was obtained charging the unit to the superheat specified by the manufacturer's charging chart for specific set of indoor and outdoor temperatures. Once the full charge was determined, the unit was subjected to 20%, 15%, 10%, and 5% under and overcharging of refrigerant (by mass). The fully charged tests were compared to under and overcharging. The performance of the unit was evaluated as a function of charge as well as at four outdoor room temperatures (82F, 90F, 95F, and 100F). As the outdoor temperature increased, the total capacity and EER dropped. The investigation of improper charging showed that the total capacity, EER, and SEER were more sensitive to undercharging than overcharging conditions. A 20% undercharge resulted in a 21% reduction in SEER while a 20% overcharge produced a 11% reduction in SEER. Other data such as refrigerant flow rate, sensible heat ratio, superheat and subcooling are also presented.

Effects of system cycling, evaporator airflow, and condenser coil fouling on the performance of residential split-system air conditioners  

E-Print Network (OSTI)

Three experimental studies were conducted to quantify the effects of system cycling, evaporator airflow, and condenser coil fouling on the performance of residential air conditioners. For all studies, the indoor dry-bulb (db) temperature was 80F (26.7C) db. The cycling study consisted of twelve transient tests conducted with an outdoor temperature of 95F (35C) db for cycle times of 6, 10, 15, and 24 minutes. Indoor relative humidities of 40%, 50%, and 60% were also considered. The evaporator airflow study consisted of twenty-four steady-state tests conducted with an indoor condition of 67F (19.4C) wet-bulb (wb) for evaporator airflows ranging from 50% below to 37.5% above rated airflow. Outdoor temperatures of 85F (29.4C) db, 95F (35C) db, and 105F (40.6C) db were also considered. The coil fouling study used a total of six condensers that were exposed to an outdoor environment for predetermined amounts of time and tested periodically. Three of the condensers were cleaned and retested during the periodic testing cycles. Testing consisted of thirty-three steady-state tests conducted with an indoor condition of 67F (19.4C) wb for outdoor exposure times of 0, 2000, 4000, and 8000 hours. Outdoor temperatures of 82F (27.8C) db and 95F (35C) db were also considered.

Monitoring the Performance of a Residential Central Air Conditioner under Degraded Conditions on a Test Bench  

E-Print Network (OSTI)

This report presents the measured degradation in performance of a residential air conditioning system operating under degraded conditions. Experiments were conducted using a R-22 threeton split-type cooling system with a short-tube orifice expansion device. Results are presented here for a series of tests in which the various commonly occurring degraded conditions were simulated on a test bench. At present, very little information is available which quantifies the performance of a residential cooling system operating under degraded conditions. Degraded performance measurements can provide information which could help electric utilities evaluate the potential impact of systemwide maintenance programs. This report also discuss the development of a diagnostic procedure based on measurement of refrigerant and air side temperatures.

Comparison of the performance of open cycle air conditioners utilizing rotary desiccant dehumidifiers  

DOE Green Energy (OSTI)

This paper presents the results of an investigation of open cycle cooling systems using rotary desiccant dehumidifiers. Three systems, the ventilation, recirculation, and Dunkle cycles have been modeled. The performance of these systems coupled with an air-based solar system has been determined using TRNSYS simulations of system operation in four representative US climates. The system COP, fraction of the total cooling load met by the desiccant system, and fraction of the thermal energy provided by solar energy are compared. An assessment of the effect of climate and system parameters on the relative performance of the three system configurations is made. It is shown that in order to meet residential loads of 7 to 11 kW with a COP on the order of unity, systems with high effectiveness must be employed. These systems were also found to perform well when operated solely with a solar thermal input.

Seasonal efficiencies of residential heat pump air conditioners with inverter-driven compressors  

SciTech Connect

This paper describes a study to experimentally determine the steady-state characteristics, cyclic effect, and frosting/defrosting effect of a inverter heat pump currently available on the Japanese market and compute its seasonal efficiency based on the local outdoor air temperature data. It has been found that the APF of this heat pump is higher by 15% than that of the conventional fixed-speed heat pump. If cyclic and frosting/defrosting losses are eliminated, the APF of the inverter heat pump will be further improved by 2% to 6%. For the evaluation of an inverter heat pump, APF alone is not sufficient, and an additional parameter such as an annual comfort factor (ACF) is needed.

Effect of refrigerant charge, duct leakage, and evaporator air flow on the high temerature performance of air conditioners and heat pumps  

E-Print Network (OSTI)

An experimental study was conducted to quantify the effect of several installation items on the high outdoor ambient temperature performance of air conditioners. These installation items were: improper amount of refrigerant charge, reduced evaporator airflow, and return air leakage from hot attic spaces. There were five sets of tests used for this research: two of them for the charging tests, two for the reduced evaporator airflow, and one for the return air leakage tests. For the charging tests, the indoor room conditions were 80'F (27.8'C) dry-bulb and 50% relative humidity. The outdoor conditions ranged from 95'F (350C) all the way up to 120'F (48.9'C). Charge levels ranged from 30% undercharged to 40% overcharged for the short-tube orifice unit. For the thermal expansion valve (TXV) unit, charge levels ranged from-36% charging to +27% charging. Performance was quantified with the following variables: total capacity, energy efficiency ratio (EER), and power. The performance of the orifice unit was more sensitive to charge than it was for the TXV unit. For the TXV unit on the -27% to +27% charging range, the capacity and EER changed little with charge. A TXV unit and a short-tube orifice unit were also tested for reduced evaporator airflow. As evaporator airflow decreased, the capacity and EER both decreased as expected. However, the drop was not as significant as with the charging tests. For the extreme case of 50% reduced evaporator airflow, neither unit's capacity or EER dropped more than 25%. Return air leakage from hot attic spaces was simulated by assuming adiabatic mixing of the indoor air at normal conditions with the attic air at high temperatures. Effective capacity and EER both decreased with increased return air leakage. However, power consumption was relatively constant for all variables except outdoor temperature, which meant that for the same power consumption, the unit delivered much lower performance when there was return air leakage. The increase in sensible heat ratio (SHR) with increasing leakage showed perhaps the most detrimental effect of return air leakage on performance, which was the inability of the unit to absorb moisture from the environment.

An Investigation of Alternative Methods for Measuring Static Pressure of Unitary Air Conditioners and Heat Pumps  

E-Print Network (OSTI)

This project was created to address an important issue currently faced by test facilities measuring static pressure for air-conditioning and heat pumps. Specifically, ASHRAE Standard 37, the industry standard for test setup, requires an outlet duct of a certain length, based on the unit outlet geometry, and this ducting added to the unit height may result in a test apparatus height that exceeds psychometric test room dimensions. This project attempted to alter the outlet duct in a way that reduces the test apparatus height while maintaining the reliability of the ASHRAE Standard 37 testing setup. The investigation was done in two scenarios, the first, which altered the direction of the flow after the unit with an elbow and measured static pressure downstream of the elbow, and the second which inserted a passive resistive piece in the flow to decrease the required distance between the unit and the static pressure measurement. Three air handling units were used in Scenario 1 and Scenario 2 testing, with the two smallest units additionally being tested in Scenario 1 with an over-sized duct. The scenario tests were required to be within 5% power and 2.5% airflow of a baseline test following ASHRAE Standard 37. he results for Scenario 1 have shown that ASHRAE Standard 37 can be modified to reduce testing height restrictions by using a square elbow with turning vanes, provided it is oriented in a specific way in relation to the blower. Furthermore, additional Scenario 1 testing on the over-sized outlet duct shows that possibilities exist for using a single over-sized duct to successfully meet ASHRAE Standard 37 testing conditions when testing a variety of units. Finally, the results of Scenario 2 have shown that the height constraints of the outlet duct can be reduced by installing a passive resistive device consisting of a mesh at the outlet; however, this approach applies only to those units with the heat exchanger located downstream of the blower. As a result of specific issues or problems that were encountered during the project that were beyond the scope, eleven case studies were presented and recommended for future work.

High-Efficiency Variable Dehumidification for Air Conditioners: ClimaStat  

SciTech Connect

Advantek has successfully developed the first low-cost technology offering significant improvement in both Seasonal Energy Efficiency (SEER) and comfort & humidity control. A production prototype was constructed based on a commercial roof top package unit. The prototype was operated under a wide range of psychrometric conditions. Test data was analyzed to identify refinements, which were implemented to further improve performance in an iterative procedure that resulted in a fully optimized technology. The latest results show an increase in dehumidification capacity of 56% with ClimaStat in full dehumidify mode vs. with ClimaStat off. Dehumidification improved by a factor of 1.7 to 1.9 meaning that the unit can provide nearly twice the water removal per unit of sensible cooling load. Performance testing results have been consistent, verifiable and repeatable. . ClimaStat cost-effectively controls humidity on-demand and improves indoor air quality while reducing annual energy costs. Test data clearly shows that ClimaStat costs 20% to 60% less to operate. ClimaStat is ready for market.

Properties and Cycle Performance of Refrigerant Blends Operating Near and Above the Refrigerant Critical Point, Task 2: Air Conditioner System Study  

SciTech Connect

The main goal of this project was to investigate and compare the performance of an R410A air conditioner to that of an R22 air conditioner, with specific interest in performance at high ambient temperatures at which the condenser of the R410A system may be operating above the refrigerant's critical point. Part 1 of this project consisted of conducting comprehensive measurements of thermophysical for refrigerant R125 and refrigerant blends R410A and R507A and developing new equation of state formulations and mixture models for predicting thermophysical properties of HFC refrigerant blends. Part 2 of this project conducted performance measurements of split-system, 3-ton R22 and R410A residential air conditioners in the 80 to 135 F (27.8 to 57.2 C) outdoor temperature range and development of a system performance model. The performance data was used in preparing a beta version of EVAP-COND, a windows-based simulation package for predicting performance of finned-tube evaporators and condensers. The modeling portion of this project also included the formulation of a model for an air-conditioner equipped with a thermal expansion valve (TXV). Capacity and energy efficiency ratio (EER) were measured and compared. The R22 system's performance was measured over the outdoor ambient temperature range of 80 to 135 F (27.8 to 57.2 C). The same test range was planned for the R410A system. However, the compressor's safety system cut off the compressor at the 135.0 F (57.2 C) test temperature. The highest measurement on this system was at 130.0 F (54.4 C). Subsequently, a custom-manufactured R410A compressor with a disabled safety system and a more powerful motor was installed and performance was measured at outdoor temperatures up to 155.0 F (68.3 C). Both systems had similar capacity and EER performance at 82.0 F (27.8 C). The capacity and EER degradation of both systems were nearly linearly dependent with rising ambient outdoor ambient test temperatures. The performance degradation of R410A at higher temperatures was greater than R22. However, the R22 and R410A systems both operated normally during all tests. Visual observations of the R410A system provided no indication of vibrations or TXV hunting at high ambient outdoor test conditions with the compressor operating in the transcritical regime.

It is considered appropriate occasionally to make independent checks on the effectiveness of the plant laundry in removing radioactive contamination from plant-issue protective clothing. Previous surveys have offered constructive criticism resulting in improved handling of high level and soft beta contaminated clothing and incorporation in new designs of ventilating and air sampling recommendations. Recurrently the adequacy of laundry reject limits is questioned, and only recently an accurate, special study resulted in relaxed limits for Metal Preparation area clothing. A current question concerns the advisability of determining the reject level on the beta-gamma monitor more frequently than once a day. 2 tabs.

Experimental study of a R-407C drop-in test on an off-the-shelf air conditioner with a counter-cross-flow evaporator  

SciTech Connect

An off-the-shelf 2-ton window air conditioner having an energy efficiency ratio of 10 was used to perform a drop-in test with R-407C. Laboratory tests were performed using a parallel-cross-flow (PCF) evaporator and a counter-cross-flow (CCF) evaporator. The CCF configuration is designed to take advantage of the temperature glide of R-407C so that the warm evaporator inlet air will be in contact with the higher temperature part of the evaporator coils first. The test results indicated that, at the Air Conditioning and Refrigeration Institute-rated indoor and outdoor conditions, the cooling capacity was 8% higher and system coefficient of performance about 3.8% higher for the CCF evaporator than for the PCF evaporator. The test results also showed that the latent load for CCF was 30.6% higher than for PCF. The far better dehumidification effect provided by the CCF evaporator design is desirable for areas where the latent load is high. The experimental findings should be useful for future efforts to design a dehumidifier that uses a zeotropic refrigerant that provides a significant temperature glide. R-22 test data from a previous project are included as a reference.

Testing of DEVAP prototype validates modeled Testing of DEVAP prototype validates modeled predictions of 40% to 85% energy savings. Researchers in the NREL Buildings group are moving the award-winning desiccant enhanced evaporative (DEVAP) air conditioning technol- ogy further toward commercialization by demonstrating that its energy-saving perfor- mance matches closely with thermodynamic model predictions. Industry partners Synapse Product Development and AIL Research built two prototypes of DEVAP based on NREL's design and modeling, which were tested in NREL's Advanced HVAC Systems Laboratory. Experiments added confidence to the predicted energy savings of 40% in humid climates and 85% in dry climates, empowering the model as a tool for developing marketable designs, and illustrating the potential of DEVAP to transform

Candidate chemical systems for air cooled, solar powered, absorption air conditioner design. Part III. Lithium salts with anti-freeze additives  

DOE Green Energy (OSTI)

The two most promising anti-solidification additives which have been identified are ethanolamine and ethylene glycol. Considerations of viscosity, corrosion, crystallization temperature and vapor pressure have led to a selection of lithium bromide - ethylene glycol - water as the basis of a prototype air-cooled machine, with the lithium bromide; ethylene glycol ratio being 4.5. Using what appear to be reasonable heat exchanger approach temperatures, cycle thermal COP's of 0.7/sup +/ appear possible at the specified design point, based on solution properties which were determined with qualification accuracy. The prototype, delivering 10,000 watts of cooling, has a calculated parasitical electrical load of about 175 watts (theoretical) to drive the internal fans and pumps, equivalent to about a 0.5 horsepower motor.

NLE Websites -- All DOE Office Websites (Extended Search)

Homeowners in the United States spend Homeowners in the United States spend one out of every eight dollars of utility costs on cooling their living space. Window air conditioners (A/Cs) are an inexpensive alternative to central systems, and are sold in greater numbers each year than all other residential cooling systems. They are purchased to cool a specific room and are easy for anyone to install. In contrast to these benefits, window A/Cs come at a cost-they operate less efficiently (using more energy to do the same cooling) than most other residential A/C systems. Researchers at the National Renewable Energy Laboratory (NREL) studied window A/Cs on behalf of the U.S.

SciTech Connect

The Energy Policy and Conservation Act (P.L. 94-163), as amended, establishes energy conservation standards for 12 of the 13 types of consumer products specifically covered by the Act. The legislation requires the Department of Energy (DOE) to consider new or amended standards for these and other types of products at specified times. DOE is currently considering amending standards for seven types of products: water heaters, direct heating equipment, mobile home furnaces, pool heaters, room air conditioners, kitchen ranges and ovens (including microwave ovens), and fluorescent light ballasts and is considering establishing standards for television sets. This Technical Support Document presents the methodology, data, and results from the analysis of the energy and economic impacts of the proposed standards. This volume presents a general description of the analytic approach, including the structure of the major models.

Low-noise pulse conditioner  

DOE Patents (OSTI)

A low-noise pulse conditioner is provided for driving electronic digital processing circuitry directly from differentially induced input pulses. The circuit uses a unique differential-to-peak detector circuit to generate a dynamic reference signal proportional to the input peak voltage. The input pulses are compared with the reference signal in an input network which operates in full differential mode with only a passive input filter. This reduces the introduction of circuit-induced noise, or jitter, generated in ground referenced input elements normally used in pulse conditioning circuits, especially speed transducer processing circuits. This circuit may be used for conditioning the sensor signal from the Fidler coil in a gas centrifuge for separation of isotopic gaseous mixtures.

How Air Conditioners Work Air conditioners employ the same operating principles and basic components as refrigerators. Refrigerators use energy (usually electricity) to transfer heat from the cool interior of the refrigerator to the relatively warm surroundings; likewise, an air conditioner uses energy to transfer heat from the interior space to the relatively warm outside environment. An air conditioner uses a cold indoor coil called the evaporator. The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine tubing surrounded by aluminum fins. This tubing is usually made of copper.

Towards believable cloth motion in computer animation  

E-Print Network (OSTI)

This thesis covers the implementation of a cloth modeling algorithm within a computer animation package. The main objective of this thesis is to prove the feasibility of simulating the behavior of cloth using an empirically based model coupled with constraint dynamics and establish the groundwork for future studies into the use of cloth models in computer animation. To achieve a quick and accurate solution, two different forward dynamic constraint based system algorithms are studied and implemented. One approach, pioneered by Breen-DeVaul-House, computes the solution to the cloth equation by breaking up the cloth model into an acyclic length constraint system that may be solved in linear time with respect to the number of constraints. This approach is well suited for cloth models that collide only with force fiends, yet, is unacceptable for the proposed application. Therefore the Breen-DeVaul-House approach is modified to incorporate collision with polygonal objects. Even though the single matrix approach does not break up the cloth model and is slower in computing a solution for a dense mesh, this approach accurately calculates collisions between a mesh and a polygonal surface through the use of surface constraints and surface force dampers.

Automobile air-conditioning unit. Final report  

SciTech Connect

In this study the refrigerant in the automobile air-conditioner is compressed by thermal energy in a unique compression system rather than by work in a standard compressor. The compression uses an intermittent compression process with a solid absorbent. The vapor is absorbed by an absorbent at relatively low temperature and ejected as the absorbent temperature is raised. A set of one way valves limits flow to one direction. Major contributions are heat transfer requirements, molecular sieve-refrigerant matching, minimizing non-producing mass, solving thermal fatigue and shock problems, and applying this to automobile air-conditioning. The performance study shows energy savings up to fifty percent are possible, depending on engine load. A twenty percent energy savings with the vehicle tested with the air-conditioner in operation is average. The study also showed that less fuel is used with the windows open than with the air-conditioner operating.

CLOTHING DECONTAMINATION AND EVALUATION OF LAUNDRY METHODS  

SciTech Connect

The over-all objectives of this project encompassed testing the suitability of standard and special laundering methods and standard equipment for field decontamination of clothing; evaluating the contaminability and decontaminability of selected fabrics, and testing of experimental clothing monitoring instruments. Garments and fabrics contaminated by controlled methods were used during the operation for testing the equipment and evaluating fabrics and formulae. 8tandard Army laundering methods and equipment, including wooden washers, were effective for decontaminating clothing in the field. A decontaminating laundry formula employing citric acid and tartaric acid followed by either an organic or inorganic chelating agent results in a higher degree of decontamination than other formulae tested. The standard Quartermaster Corps mobile field laundry formula resulted in satisfactory decontamination with the type of soil and activity encountered and the cost of supplies is approximately one-tenth as much as the special formulae. Woolen garments and fabric swatches were decontanninated by laundering as readily as cotton or synthetic fabrics. Clothing monitoring instruments under development appear suitable for monitoring clothing under field conditions to determine the degree of contamination both before and after precessing. (auth)

POSSIBLE HEALTH HAZARDS ASSOCIATED WITH THE LAUNDERING OF RADIOACTIVELY CONTAMINATED PROTECTIVE CLOTHING  

SciTech Connect

An engineering study was made at the Brookhaven National Laboratory to evaluate the possible health hazards to laundry personnel and the public connected with the operation of a decontamination laundry. Laboratory clothing was separated into eight groups, ranging from only slight amounts to rather large amounts of contamination. The groups contained from nineteen to thirtyone coveralls each, with all of the garments in the same group containing about the same amount of radioactive contamination. Each group was washed as a separate batch. Air samples were taken at various breathing zones and at various times during the operation to determine the air-borne dust hazard. The waste water was assayed for actlvity, the dryer effluent was monitored and the equipment, building, etc., were checked for contamination during the laundry operation of the eight groups. The data show that the greatest hazard lies in the inhalation of airbonne radioactive dusts. Washwater, laundry equipment, surfaces and floors became contaminated. Clean clothes showed cross contamination if washed with even slightly contaminated clothing. The dryer effluent was invariably contaminated with radioactive lint. It was evident that below 1 to 2 mu c of contamination per garment, one could send radioactive clothing to a commercial laundry without hazard to the laundry operators or to the public. Higher levels can be handled safely by a commercial laundry if the loading and sorting operations are carefully managed. (auth)

Franco, and Stephen Meyers Journal Energy Efficiency Date Published 05/2013 Keywords appliance standards, energy efficiency Abstract This article describes the analysis of monetary and energy savings attributable to various energy efficiency levels considered as potential US federal standards for residential clothes dryers. The analysis examined benefits to both consumers and the nation as a whole. Benefits to consumers were evaluated based on the life-cycle cost of affected appliances and the payback period associated with increased first costs. Benefits to the nation incorporate both energy and financial savings associated with each potential efficiency standard. The analysis incorporated the most current information on field use of clothes dryers, which shows that dryer usage and the moisture in clothes are less than previously thought. The analysis found that high-efficiency heat pump clothes dryers would be cost-effective for nearly one fifth of US households. However, for both electric standard and gas clothes dryers, standards that improve efficiency by 5 % appear to be the highest levels that have a positive net present value of consumer benefit.

Residential Humidity Control: Exciting New Opportunities with Air Flow Modulation  

E-Print Network (OSTI)

This paper reviews psychrometric principles and shows how to formulate a psychrometric chart from a single equation. The chart is used to demonstrate the manner in which a conventional single-speed air conditioner adjusts its operating point in an attempt to control humidity over a range of conditions. The system performance with an electronically commutated motor (ECM) driving the blower is then presented. With ECM blower speed control, it is possible to raise the sensible capacity, reduce the sensible capacity, and boost the efficiency of an otherwise conventional air conditioner. This makes such systems ideal to respond to the changing loads in a hot and humid climate.

Air Conditioning with Magnetic Refrigeration : An Efficient, Green Compact Cooling System Using Magnetic Refrigeration  

SciTech Connect

BEETIT Project: Astronautics is developing an air conditioning system that relies on magnetic fields. Typical air conditioners use vapor compression to cool air. Vapor compression uses a liquid refrigerant to circulate within the air conditioner, absorb the heat, and pump the heat out into the external environment. Astronautics design uses a novel property of certain materials, called magnetocaloric materials, to achieve the same result as liquid refrigerants. These magnetocaloric materials essentially heat up when placed within a magnetic field and cool down when removed, effectively pumping heat out from a cooler to warmer environment. In addition, magnetic refrigeration uses no ozone-depleting gases and is safer to use than conventional air conditioners which are prone to leaks.

Under conditions resulting from surface and underground detonations of atomic bombs, tests were conducted on Chemical Corps impregnated and unimpregnated protective clothing, Individual Protective Mask M9A1 with M11 Canister, Tank Collective Protector E26 and E22, and Protective Ointment M5. Both impregnated and unimpregnated clothing were capable of preventing contact between the skin and radioactive dusts. Unimpregnated clothing demonstrated better contanmination-decontamination characteristics, but the secondary radiation from all clothing was negligible. The protective cover was effective in preventing contamination of clothing. The M9A1 mask with M11 canister furnished complete protection against inhalation of radioactive dust. The flltering efficiencies of the E26 tank collective protectors were found to be very high, and no deficiencies were found in the unit. The filtering efficiencies of the E22 tank collective protectors were also high. Panels coated with M5 ointment were found to be much more highly contaminated than bare panels. (auth)

Bern clothes washer study. Final report  

SciTech Connect

The US market for domestic clothes washers is currently dominated by conventional, vertical axis washers, which typically require about 40 gallons of water for each load. Although small for an individual load, the fact that 35 billion loads of laundry are washed annually in the US results in a substantial quantity of water and energy use. Although much smaller, today`s market for high-efficiency clothes washers which use much less water and energy is growing albeit slowly as manufacturers are making washers based around tumble-action, horizontal axis designs available, information about their performance and benefits is being developed, and consumers are made aware of these benefits. To help build awareness of these benefits and to accelerate markets for high-efficiency washers, DOE, under its Energy Star Program and in cooperation with Maytag Appliances, conducted a field-evaluation of high-efficiency washers using Bern, Kansas (population approximately 200) as a test bed. Baseline washer performance data as well as customer washing behavior were obtained from data collected on the existing washers of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional washers were replaced by high-efficiency, tumble action washers, and the experiment continued for another 3-month period. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined and reported.

Making the Optimal Decision in Selecting Protective Clothing  

Science Conference Proceedings (OSTI)

Protective Clothing plays a major role in the decommissioning and operation of nuclear facilities. Literally thousands of dress-outs occur over the life of a decommissioning project and during outages at operational plants. In order to make the optimal decision on which type of protective clothing is best suited for the decommissioning or maintenance and repair work on radioactive systems, a number of interrelating factors must be considered. This article discusses these factors as well as surveys of plants regarding their level of usage of single use protective clothing and should help individuals making decisions about protective clothing as it applies to their application. Individuals considering using SUPC should not jump to conclusions. The survey conducted clearly indicates that plants have different drivers. An evaluation should be performed to understand the facility's true drivers for selecting clothing. It is recommended that an interdisciplinary team be formed including representatives from budgets and cost, safety, radwaste, health physics, and key user groups to perform the analysis. The right questions need to be asked and answered by the company providing the clothing to formulate a proper perspective and conclusion. The conclusions and recommendations need to be shared with senior management so that the drivers, expected results, and associated costs are understood and endorsed. In the end, the individual making the recommendation should ask himself/herself: 'Is my decision emotional, or logical and economical?' 'Have I reached the optimal decision for my plant?'.

Method for Evaluating Energy Use of Dishwashers, Clothes Washers, and Clothes Dryers: Preprint  

SciTech Connect

Building America teams are researching opportunities to improve energy efficiency for some of the more challenging end-uses, such as lighting (both fixed and occupant-provided), appliances (clothes washer, dishwasher, clothes dryer, refrigerator, and range), and miscellaneous electric loads, which are all heavily dependent on occupant behavior and product choices. These end-uses have grown to be a much more significant fraction of total household energy use (as much as 50% for very efficient homes) as energy efficient homes have become more commonplace through programs such as ENERGY STAR and Building America. As modern appliances become more sophisticated the residential energy analyst is faced with a daunting task in trying to calculate the energy savings of high efficiency appliances. Unfortunately, most whole-building simulation tools do not allow the input of detailed appliance specifications. Using DOE test procedures the method outlined in this paper presents a reasonable way to generate inputs for whole-building energy-simulation tools. The information necessary to generate these inputs is available on Energy-Guide labels, the ENERGY-STAR website, California Energy Commission's Appliance website and manufacturer's literature. Building America has developed a standard method for analyzing the effect of high efficiency appliances on whole-building energy consumption when compared to the Building America's Research Benchmark building.

Building America teams are researching opportunities to improve energy efficiency for some of the more challenging end-uses, such as lighting (both fixed and occupant-provided), appliances (clothes washer, dishwasher, clothes dryer, refrigerator, and range), and miscellaneous electric loads, which are all heavily dependent on occupant behavior and product choices. These end-uses have grown to be a much more significant fraction of total household energy use (as much as 50% for very efficient homes) as energy efficient homes have become more commonplace through programs such as ENERGY STAR and Building America. As modern appliances become more sophisticated the residential energy analyst is faced with a daunting task in trying to calculate the energy savings of high efficiency appliances. Unfortunately, most whole-building simulation tools do not allow the input of detailed appliance specifications. Using DOE test procedures the method outlined in this paper presents a reasonable way to generate inputs for whole-building energy-simulation tools. The information necessary to generate these inputs is available on Energy-Guide labels, the ENERGY-STAR website, California Energy Commission's Appliance website and manufacturer's literature. Building America has developed a standard method for analyzing the effect of high efficiency appliances on whole-building energy consumption when compared to the Building America's Research Benchmark building.

Science Conference Proceedings (OSTI)

Air-source heat pump systems offer an alternative to the common heating, ventilating, and air conditioning (HVAC) configuration of single split unitary air conditioners with gas heating. In simple terms, heat pumps are traditional air conditioning units with the added capability of running in reverse as required by the building load. Thus, where the traditional air conditioning unit has an indoor evaporator to remove heat from the space and an outdoor condenser to reject heat to the ambient environment, ...

A review of polymer-based water conditioners for reduction of handling-related injury  

Science Conference Proceedings (OSTI)

Fish are coated with an external layer of protective mucus. This layer serves as the primary barrier against infection or injury, reduces friction, and plays a role in ionic and osmotic regulation. However, the mucus layer is easily disturbed when fish are netted, handled, transported, stressed, or subjected to adverse water conditions. Water additives containing polyvinylpyrrolidone (PVP) or proprietary polymers have been used to prevent the deleterious effects of mucus layer disturbances in the commercial tropical fish industry, aquaculture, and for other fisheries management purposes. This paper reviews research on the effectiveness of water conditioners, and examines the contents and uses of a wide variety of commercially available water conditioners. Water conditioners containing polymers may reduce external damage to fish held in containers during scientific experimentation, including surgical implantation of electronic tags. However, there is a need to empirically test the effectiveness of water conditioners at preventing damage to and promoting healing of the mucus layer. A research agenda is provided to advance the science related to the use of water conditions to improve the condition of fish during handling and tagging.

Candidate chemical systems for air cooled solar powered, absorption air conditioner design. Part I. Organic absorbent systems  

DOE Green Energy (OSTI)

All the available experimental evidence suggests that the optimum ''organic'' absorbent/refrigerant combination would be a methane derivative with a single hydrogen atom with chlorine and fluorine atoms in the other sites, as refrigerant. This would be hydrogen bonded to an absorbent molecule containing the group =NC/sup -/O, with the substituent groups being such that no steric hindrance took place. Cycle analyses showed that the ratio of internal heat transfer to cooling would be large, probably impractically so in view of the high coefficient of performance needed for solar driven cooling and the additional handicap of heat rejection to the atmosphere. A more promising approach would be to reduce the internal heat transfer per unit of space cooling by selecting a refrigerant with a high latent heat of vaporization and selecting an absorbent with suitable properties.

Work done in attempting to qualify absorption refrigeration systems based on refrigerants with intermediate latent heats of vaporization is summarized. In practice, these comprise methanol, ammonia, and methylamine. A wide variety of organic substances, salts, and mixtures were evaluated in as systematic a manner as possible. Several systems of interest are described. The system, LiClO/sub 3/--LiBr--H/sub 2/O, is a good back up system to our first choice of an antifreeze additive system, and thermodynamically promising but subject to some inconvenient materials limitations. The system, LiBr/ZnBr/sub 2/--methanol, is thermodynamically promising but requires additional kinetic qualification. Chemical stability of the system, LiCNS--ammonia/methylamine with various other third components, does not appear to be adequate for a long-lived system.

Reducing air conditioning waste by signalling it is cool outside  

SciTech Connect

This experiment looked at the effects on residential energy consumption of providing homeowners with (1) a signalling device that indicated a conservation opportunity and (2) information feedback about their rate of energy use. The signalling device operated when the outside temperature was below 68F and the air conditioner was on. Homeowners were told that the signalling device indicated when they could cool their house effectively by opening the windows and turning off their air conditioner. Forty households were randomly assigned to one of four conditions: signalling device only, feedback only, both, neither. The results showed a significant 15.7% decrease in energy use for those households with the signalling devices. Neither the feedback nor interaction effect was significant. The advantages and disadvantages of having people in the control cycle were discussed. 4 references, 1 table.

Analysis of historical residential air-conditioning equipment sizing using monitored data  

SciTech Connect

Monitored data were analyzed to determine whether residential air conditioners in the Pacific Northwest historically have been sized properly to meet or slightly exceed actual cooling requirements. Oversizing air-conditioning equipment results in a loss of efficiency because of increased cycling and also lowers humidity control. On the other hand, the penalty of undersizing air-conditioning equipment may be some loss of comfort during extremely hot weather. The monitored data consist of hourly space-conditioning electrical energy use and internal air temperature data collected during the past 7 years from 75 residences in the Pacific Northwest. These residences are equipped with central air conditioners or heat pumps. The periods with the highest cooling energy use were analyzed for each site. A standard industry sizing methodology was used for each site to determine a sizing estimate. Both the sizing recommendation based on Manual J and peak monitored loads are compared to the capacity of the installed equipment for each site to study how the actual capacity differed from both the estimate of proper sizing and from actual demands. Characteristics of the maximum cooling loads are analyzed here to determine which conditions put the highest demand on the air conditioner. Specifically, internal air temperature data are used to determine when the highest cooling loads occur, at constant thermostat settings or when the thermostat was set down. This analysis of monitored data also provides insight into the extent that occupant comfort may be affected by undersizing air conditioners. The findings of this research indicate that cooling equipment historically has often but not always been oversized beyond industry-recommended levels. However, some occupants in homes with undersized, properly sized, and, in rare occasions, even oversized cooling equipment appear to suffer because the cooling equipment cannot always provide adequate cooling.

A Field Study on Residential Air Conditioning Peak Loads During Summer in College Station, Texas  

E-Print Network (OSTI)

Severe capacity problems are experienced by electric utilities during hot summer afternoons. Several studies have found that, in large part, electric peak loads can be attributed to residential airconditioning use. This air-conditioning peak depends primarily on two factors: (i) the manner in which the homeowner operates his air-conditioner during the hot summer afternoons, and (ii) the amount by which the air-conditioner has been over-designed. Whole-house and air-conditioner electricity use data at 15 minute time intervals have been gathered and analyzed for 8 residences during the summer of 1991, six of which had passed the College Station Good Cents tests. Indoor air temperatures were measured by a mechanical chart recorder, while a weather station located on the main campus of Texas A&M university provided the necessary climatic data, especially ambient temperature, relative humidity and solar radiation. The data were analysed to determine the extent to which air-conditioning over-sizing and homeowner intervention contributes to peak electricity use for newer houses in College Station, Texas.

Research on Thermal Properties in a Phase Change Wallboard Room Based on Air Conditioning Cold Storage  

E-Print Network (OSTI)

After comparing the thermal performance parameters of an ordinary wall room to a phase change wall (PCW) room, we learn that phase change wallboard affects the fluctuation of temperature in air-conditioning room in the summer. We built a PCW room and an ordinary wall room, which are cooled by an air-conditioner. We used differential scanning calorimetry (DSC) to test the temperature field and heat flow fluctuation in these rooms. Through analyzing the data tested, we found that the mean temperature of PCW is lower than that of ordinary wall room by 1 to 2?, and PCW can lower the heat flow by 4.6W/m2. Combining phase change material with the building envelope can lower the indoor temperature, make the room thermally comfortable, and cut down the turn-on-and-off frequency of the air-conditioner and the primary investment and operating costs. It alleviates the urgent need for electricity.

Keeping cool on the job. [Heat-resistant protective clothing  

SciTech Connect

Maintenance workers at nuclear power plants need special protective clothing that slows overheating from the 55/sup 0/C temperature caused by waste heat from pipes and pressure vehicles. Cooling garments increase efficiency by extending the time workers can function, as well as safeguarding their health and morale. The Electric Power Research Institute evaluated two cooling concepts: circulating liquid suits already available on the market and a prototype frozen-water garment. Performance tests of the frozen-water suit found that it can more than double the 65-minute stay-time of liquid-cooled systems. The frozen-water garment permits mobility, is compatible with radiation protection and other garments and equipment, is easty to clean or decontaminate, has no moving parts, and is attractively priced. 4 figures.

Improving air handler efficiency in houses  

SciTech Connect

Although furnaces, air conditioners and heat pumps have become significantly more efficient over the last couple of decades, residential air handlers have typical efficiencies of only 10% to 15% due to poor electric motor performance and aerodynamically poor fans and fan housings. Substantial increases in performance could be obtained through improved air handler design and construction. A prototype residential air handler intended to address these issues has recently been developed. The prototype and a standard production fan were tested in a full-scale duct system and test chamber at LBNL specifically designed for testing heating, ventilation, and air conditioning systems. The laboratory tests compared efficiency, total airflow, sensitivity to duct system flow resistance, and the effects of installation in a smaller cabinet. The test results showed that the prototype air handler had about twice the efficiency of the standard air handler (averaged over a wide range of operating conditions) and was less sensitive to duct system flow resistance changes. The performance of both air handlers was significantly reduced by reducing the clearance between the air handler and cabinet it was placed in. These test results showed that in addition to the large scope for performance improvement, air handler fans need to be tested in the cabinets they operate in.

Solar-assisted electric clothes dryer using a home attic as a heat source  

DOE Green Energy (OSTI)

This study was undertaken to determine the suitability of using a southeastern home attic as a means of reducing the energy consumption of an electric clothes dryer. An inexpensive duct (duplicable for $25) was constructed to collect hot attic air from the peak of a south facing roof and introduce it into the dryer inlet. Instrumentation was added to measure inlet temperatures and operating time/energy consumption of the dryer. Standardized test loads, in addition to normal laundry, were observed over the period of one year. The heat-on time of the dryer tested was shown to be reduced .16 to .35 minutes per /sup 0/C rise in inlet temperature. Inlet temperatures produced by the attic duct peaked at 56/sup 0/C(133/sup 9/F) in May/June and 40/sup 0/C(104/sup 0/F) in February. Based on peak temperatures available between 2 and 4 pm each month, a potential 20% yearly average savings could be realized. Economic viability of the system, dependant primarily on dryer usage, can be computed using a formula derived from the test results and included in the report.

Innovative Evaporative and Innovative Evaporative and Thermally Activated Technologies Improve Air Conditioning Researchers at the National Renewable Energy Laboratory (NREL) invented a breakthrough technology that improves air conditioning in a novel way-with heat. NREL combined desiccant materials, which remove moisture from the air using heat, and advanced evaporative technologies to develop a cooling unit that uses 90% less electricity and up to 80% less total energy than traditional air conditioning (AC). This solution, called the desiccant enhanced evaporative air conditioner (DEVap), also controls humidity more effectively to improve the comfort of people in buildings. Desiccants are an example of a thermally activated technology (TAT) that relies on heat instead

Horizontal-axis clothes washer market poised for expansion  

SciTech Connect

The availability of energy- and water-efficient horizontal-axis washing machines in the North American market is growing, as US and European manufacturers position for an expected long-term market shift toward horizontal-axis (H-axis) technology. Four of the five major producers of washing machines in the US are developing or considering new H-axis models. New entrants, including US-based Staber Industries and several European manufacturers, are also expected to compete in this market. The intensified interest in H-axis technology is partly driven by speculation that new US energy efficiency standards, to be proposed in 1996 and implemented in 1999, will effectively mandate H-axis machines. H-axis washers typically use one-third to two-thirds less energy, water, and detergent than vertical-axis machines. Some models also reduce the energy needed to dry the laundry, since their higher spin speeds extract more water than is typical with vertical-axis designs. H-axis washing machines are the focus of two broadly-based efforts to support coordinated research and incentive programs by electric, gas, and water utilities: The High-Efficiency Laundry Metering/Marketing Analysis (THELMA), and the Consortium for Energy Efficiency (CEE) High-Efficiency Clothes Washer Initiative. These efforts may help to pave the way for new types of marketing partnerships among utilities and other parties that could help to speed adoption of H-axis washers.

Do Heat Pump Clothes Dryers Make Sense for the U.S. Market  

SciTech Connect

Heat pump clothes dryers (HPCDs) can be as much as 50percent more energy-efficient than conventional electric resistance clothes dryers, and therefore have the potential to save substantial amounts of electricity. While not currently available in the U.S., there are manufacturers in Europe and Japan that produce units for those markets. Drawing on analysis conducted for the U.S. Department of Energy's (DOE) current rulemaking on amended standards for clothes dryers, this paper evaluates the cost-effectiveness of HPCDs in American homes, as well as the national impact analysis for different market share scenarios. In order to get an accurate measurement of real energy savings potential, the paper offers a new energy use calculation methodology that takes into account the most current data on clothes washer cycles, clothes dryer usage frequency, remaining moisture content, and load weight per cycle, which is very different from current test procedure values. Using the above methodology along with product cost estimates developed by DOE, the paper presents the results of a life-cycle cost analysis of the adoption of HPCDs in a representative sample of American homes. The results show that HPCDs have positive economic benefits only for households with high clothes dryer usage or for households with high electricity prices and moderately high utilization.

Avoiding 100 new power plants by increasing efficiency of room air conditioners in India: opportunities and challenges  

SciTech Connect

Electricity demand for room ACs is growing very rapidly in emerging economies such as India. We estimate the electricity demand from room ACs in 2030 in India considering factors such as weather and income growth using market data on penetration of ACs in different income classes and climatic regions. We discuss the status of the current standards, labels, and incentive programs to improve the efficiency of room ACs in these markets and assess the potential for further large improvements in efficiency and find that efficiency can be improved by over 40% cost effectively. The total potential energy savings from Room AC efficiency improvement in India using the best available technology will reach over 118 TWh in 2030; potential peak demand saving is found to be 60 GW by 2030. This is equivalent to avoiding 120 new coal fired power plants of 500 MW each. We discuss policy options to complement, expand and improve the ongoing programs to capture this large potential.

Desiccant Enhanced Evaporative Air-Conditioning (DEVap): Evaluation of a New Concept in Ultra Efficient Air Conditioning  

SciTech Connect

NREL has developed the novel concept of a desiccant enhanced evaporative air conditioner (DEVap) with the objective of combining the benefits of liquid desiccant and evaporative cooling technologies into an innovative 'cooling core.' Liquid desiccant technologies have extraordinary dehumidification potential, but require an efficient cooling sink. DEVap's thermodynamic potential overcomes many shortcomings of standard refrigeration-based direct expansion cooling. DEVap decouples cooling and dehumidification performance, which results in independent temperature and humidity control. The energy input is largely switched away from electricity to low-grade thermal energy that can be sourced from fuels such as natural gas, waste heat, solar, or biofuels.

Future Air Conditioning Energy Consumption in Developing Countriesand what can be done about it: The Potential of Efficiency in theResidential Sector  

SciTech Connect

The dynamics of air conditioning are of particular interestto energy analysts, both because of the high energy consumption of thisproduct, but also its disproportionate impact on peak load. This paperaddresses the special role of this end use as a driver of residentialelectricity consumption in rapidly developing economies. Recent historyhas shown that air conditioner ownership can grow grows more rapidly thaneconomic growth in warm-climate countries. In 1990, less than a percentof urban Chinese households owned an air conditioner; by 2003 this numberrose to 62 percent. The evidence suggests a similar explosion of airconditioner use in many other countries is not far behind. Room airconditioner purchases in India are currently growing at 20 percent peryear, with about half of these purchases attributed to the residentialsector. This paper draws on two distinct methodological elements toassess future residential air conditioner 'business as usual' electricityconsumption by country/region and to consider specific alternative 'highefficiency' scenarios. The first component is an econometric ownershipand use model based on household income, climate and demographicparameters. The second combines ownership forecasts and stock accountingwith geographically specific efficiency scenarios within a uniqueanalysis framework (BUENAS) developed by LBNL. The efficiency scenariomodule considers current efficiency baselines, available technologies,and achievable timelines for development of market transformationprograms, such as minimum efficiency performance standards (MEPS) andlabeling programs. The result is a detailed set of consumption andemissions scenarios for residential air conditioning.

Room airconditioner purchases in India are currently growing at 20 percent peryear, with about half of these purchases attributed to the residentialsector. This paper draws on two distinct methodological elements toassess future residential air conditioner 'business as usual' electricityconsumption by country/region and to consider specific alternative 'highefficiency' scenarios. The first component is an econometric ownershipand use model based on household income, climate and demographicparameters. The second combines ownership forecasts and stock accountingwith geographically specific efficiency scenarios within a uniqueanalysis framework (BUENAS) developed by LBNL. The efficiency scenariomodule considers current efficiency baselines, available technologies,and achievable timelines for development of market transformationprograms, such as minimum efficiency performance standards (MEPS) andlabeling programs. The result is a detailed set of consumption andemissions scenarios for residential air conditioning.

Magnetic Refrigeration Technology for High Efficiency Air Conditioning  

SciTech Connect

Magnetic refrigeration was investigated as an efficient, environmentally friendly, flexible alternative to conventional residential vapor compression central air conditioning systems. Finite element analysis (FEA) models of advanced geometry active magnetic regenerator (AMR) beds were developed to minimize bed size and thus magnet mass by optimizing geometry for fluid flow and heat transfer and other losses. Conventional and magnetocaloric material (MCM) regenerator fabrication and assembly techniques were developed and advanced geometry passive regenerators were built and tested. A subscale engineering prototype (SEP) magnetic air conditioner was designed, constructed and tested. A model of the AMR cycle, combined with knowledge from passive regenerator experiments and FEA results, was used to design the regenerator beds. A 1.5 Tesla permanent magnet assembly was designed using FEA and the bed structure and plenum design was extensively optimized using FEA. The SEP is a flexible magnetic refrigeration platform, with individually instrumented beds and high flow rate and high frequency capability, although the current advanced regenerator geometry beds do not meet performance expectations, probably due to manufacturing and assembly tolerances. A model of the AMR cycle was used to optimize the design of a 3 ton capacity magnetic air conditioner, and the system design was iterated to minimize external parasitic losses such as heat exchanger pressure drop and fan power. The manufacturing cost for the entire air conditioning system was estimated, and while the estimated SEER efficiency is high, the magnetic air conditioning system is not cost competitive as currently configured. The 3 ton study results indicate that there are other applications where magnetic refrigeration is anticipated to have cost advantages over conventional systems, especially applications where magnetic refrigeration, through the use of its aqueous heat transfer fluid, could eliminate intermediate heat exchangers or oil distribution issues found in traditional vapor compression systems.

Washing of Cloth Contaminated with Radionuclides Using A Detergent-Free Laundry System  

SciTech Connect

In this study, we describe a new laundry system to wash clothes, including those contaminated with radionuclides, without using detergent. The main part of this system is electrolytic cell that consists of a cathode with a special coating of nickel, an anode of nickel, and a cation exchange membrane between the two electrodes. The electrolyte is supplied to the anode and the tap-water to the cathode. When an electricity of 5 volts and 25 amperes is applied to the electrodes, the processed water is produced from the cathode. This processed water containing no detergent was investigated experimentally with regard to its decontamination efficiency of radionuclides and detergency of soil as compared to the conventional washing using detergent. It was found that the processed water from this system has an ability to simultaneously remove radionuclides and soil from the cloth with good efficiency.

A comparison of the electrochemical behavior of carbon aerogels and activated carbon fiber cloths  

SciTech Connect

Electrochemical capacitative behavior of carbon aerogels and commercial carbon fiber cloths was studied in 5M KOH, 3M sulfuric acid, and 0.5M tetrethylammonium tetrafluoroborate/propylene carbonate electrolytes. The resorcinol-formaldehyde based carbon aerogels with a range of denisty (0.2-0.85 g/cc) have open-cell structures with ultrafine pore sizes (5-50 nm), high surface area (400-700 m{sup 2}/g), and a solid matrix composed of interconnected particles or fibers with characteristic diameters of 10 nm. The commercial fiber cloths in the density range 0.2-04g/cc have high surface areas (1000-2500 m{sup 2}/g). The volumetric capacitances of high-density aerogels are shown to be comparable to or exceeding those from activated carbon fibers. Electrochemical behavior of these materials in various electrolytes is compared and related to their physical properties.

Pore geometry in woven fiber structures: 0{degree}/90{degree} plain-weave cloth layup preform  

Science Conference Proceedings (OSTI)

Composite preform fiber architectures range from the very simple to the complex, and the extremes are typified by parallel continuous fibers and complicated three-dimensional woven structures. Subsequent processing of these preforms to produce dense composites may depend critically on the geometry of the interfiber porosity. The goal of this study is to fully characterize the structure of a 0{degree}/90{degree} cloth layup preform using x-ray tomographic microscopy (XTM). This characterization includes the measurement of intercloth channel widths and their variability, the transverse distribution of through-cloth holes, and the distribution of preform porosity. The structure of the intercloth porosity depends critically on the magnitude and direction of the offset between adjacent cloth layers. The structures observed include two-dimensional networks of open pipes linking adjacent holes, arrays of parallel one-dimensional pipes linking holes, and relatively closed channels exhibiting little structure, and these different structures would appear to offer very different resistances to gas flow through the preform. These measurements, and future measurements for different fiber architectures, will yield improved understanding of the role of preform structure on processing. {copyright} {ital 1998 Materials Research Society.}

Measured impacts of high efficiency domestic clothes washers in a community  

SciTech Connect

The US market for domestic clothes washers is currently dominated by conventional vertical-axis washers that typically require approximately 40 gallons of water for each wash load. Although the current market for high efficiency clothes washers that use much less water and energy is quite small, it is growing slowly as manufacturers make machines based on tumble action, horizontal-axis designs available and as information about the performance and benefits of such machines is developed and made available to consumers. To help build awareness of these benefits and to accelerate markets for high efficiency washers, the Department of Energy (DOE), under its ENERGY STAR{reg_sign} Program and in cooperation with a major manufacturers of high efficiency washers, conducted a field evaluation of high efficiency washers using Bern, Kansas as a test bed. Baseline washing machine performance data as well as consumer washing behavior were obtained from data collected on the existing machines of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional machines were replaced by high efficiency, tumble-action washers, and the study continued for 3 months. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined. The study, its findings, and how information from the experiment was used to improve national awareness of high efficiency clothes washer benefits are described in this paper.

Air Conditioning Stall Phenomenon Testing, Model Development, and Simulation  

Science Conference Proceedings (OSTI)

Electric distribution systems are experiencing power quality issues of extended reduced voltage due to fault-induced delayed voltage recovery (FIDVR). FIDVR occurs in part because modern air conditioner (A/C) and heat pump compressor motors are much more susceptible to stalling during a voltage sag or dip such as a sub-transmission fault. They are more susceptible than older A/C compressor motors due to the low inertia of these newer and more energy efficient motors. There is a concern that these local reduced voltage events on the distribution system will become more frequent and prevalent and will combine over larger areas and challenge transmission system voltage and ultimately power grid reliability. The Distributed Energy Communications and Controls (DECC) Laboratory at Oak Ridge National Laboratory (ORNL) has been employed to (1) test, (2) characterize and (3) model the A/C stall phenomenon.

H-Coal pilot plant. Topical report: evaluation of a commercial laundry process for cleaning work clothing from a synthetic-fuels facility, E and H-12  

SciTech Connect

A scientific study was undertaken by Ashland Synthetic Fuels, Inc., to evaluate the cleaning efficiency of work clothing from the H-Coal Pilot Plant by a commercial laundry facility. Laundry process conditions for cleaning clothes were determined, and procedures were developed for laboratory analysis to detect coal liquefaction heavy distillate in work clothing and laundry wastewater. Laboratory testing and longwave ultraviolet light were used to monitor for skin contamination from recycled work clothing. Laboratory studies with spiked, unwashed cloth swatches showed a heavy distillate recovery efficiency of 86%. The laundry process was found to remove 98% of heavy distillate from spiked, washed cloth swatches. Low levels of heavy distillate and three polynuclear aromatic hydrocarbons were found in laundry wastewater, recycled work shirts and uncleaned T-shirts worn in process areas. Hydrocarbon material content in wastewater can be satisfactorily treated by process wastewater treatment units at synfuels facilities. There were data to suggest that process material accumulates in recycled work shirts (outer clothing) to about three times the level in new control shirts, but this accumulation was not noted in T-shirts (underclothing). Although residual process material was found in work shirts and gloves after cleaning, skin fluorescence monitoring with ultraviolet light indicates that skin contamination from contact with recycled gloves and work shirts is not occurring.

Cascade Reverse Osmosis Air Conditioning System: Cascade Reverse Osmosis and the Absorption Osmosis Cycle  

SciTech Connect

BEETIT Project: Battelle is developing a new air conditioning system that uses a cascade reverse osmosis (RO)-based absorption cycle. Analyses show that this new cycle can be as much as 60% more efficient than vapor compression, which is used in 90% of air conditioners. Traditional vapor-compression systems use polluting liquids for a cooling effect. Absorption cycles use benign refrigerants such as water, which is absorbed in a salt solution and pumped as liquidreplacing compression of vapor. The refrigerant is subsequently separated from absorbing salt using heat for re-use in the cooling cycle. Battelle is replacing thermal separation of refrigerant with a more efficient reverse osmosis process. Research has shown that the cycle is possible, but further investment will be needed to reduce the number of cascade reverse osmosis stages and therefore cost.

3-1 3-1 CHAPTER 3 FILTERS FOR THE NUCLEAR INDUSTRY 3.1 Introduction Filters are widely used in nuclear ventilation, air cleanup, and confinement systems to remove particulate matter from air and gas streams. Air filters are defined as porous structures through which air is passed to separate out entrained particulate matter. The word "filter" is derived from a word for the fabric called felt, pieces of which have been used for air and liquid filtration for hundreds of years. The porous structures of a filter may also be composed of granular material such as sand or fibers derived from cotton, minerals (glass, asbestos), metals, or a wide selection of plastic materials. For filtration purposes, the fibers may be woven or felted into a cloth or formed into a paper-like structure. Filters may also be constructed in the form of highly

State-of-the-Art in Residential and Small Commercial Air HandlerPerformance  

SciTech Connect

Although furnaces, air conditioners, and heat pumps have become significantly more efficient over the last couple of decades, residential air handlers have typical efficiencies of only 10% to 15% due to poor electric motor and aerodynamic performance. These low efficiencies indicate that there is significant room for improvement of air handler fans. The other 85-90% of the electricity used by air handlers is manifested as heat. This extra heat reduces air conditioning cooling and dehumidification performance and effectively acts as fuel switching for fossil fueled furnaces. For electric furnaces, this heat substitutes directly for the electric resistance heating elements. For heat pumps, this heat substitutes for compressor-based high COP heating and effectively reduces the COP of the heat pump. Using a combination of field observations and engineering judgment they can assemble a list of the problems that lead to low air handler efficiency and potential solutions to these problems, as shown. None of the problems require exotic or complex solutions and there are no technological barriers to adopting them. Some of the solutions are simple equipment swaps (using better electric motors), others require changes to the way the components are built (tighter tolerances) and other relate to HVAC equipment design (not putting large fans in small cabinets).

Air humidity requirements for human comfort  

SciTech Connect

Upper humidity limits for the comfort zone determined from two recently presented models for predicting discomfort due to skin humidity and insufficient respiratory cooling are proposed. The proposed limits are compared with the maximum permissible humidity level prescribed in existing standards for the thermal indoor environment. The skin humidity model predicts discomfort as a function of the relative humidity of the skin, which is determined by existing models for human heat and moisture transfer based on environmental parameters, clothing characteristics, and activity level. The respiratory model predicts discomfort as a function of the driving forces for heat loss from the respiratory tract, namely, the temperature and humidity of the surrounding air. An upper humidity limit based on a relative skin humidity of 0.54, corresponding to 20% dissatisfied, results in a maximum permissible humidity level near 100% RH. The requirements for respiratory comfort are much more stringent and result in lower permissible indoor air humidities. Compared with the upper humidity limit specified in existing thermal comfort standards, e.g., ASHRAE Addendum 55a, the humidity limit based on skin humidity was less restrictive and the humidity limit based on respiratory comfort was far more restrictive.

Diphenylamine traces in handswabs and clothing debris: cleanup and liquid chromatography with sequential oxidative and reductive electrochemical detection  

SciTech Connect

Because of its low basicity, diphenylamine (DPA) absorbed from acetonitrile onto a strongly acidic cation exchange resin is readily displaced by small amounts of water. Hence, microcolumns of the resin may be used in the selective recovery of DPA from clothing debris and from handswab extracts. The eluates are analyzed by high-performance liquid chromatography with oxidative detection at porous graphite electrodes, when DPA undergoes a four-electron oxidation, followed by reductive detection of the oxidation product at a pendent mercury drop electrode. Some examples are quoted of background amounts of DPA that overlap the published results of DPA transfer due to firearms discharge.

Predictions of thermal comfort and pollutant distributions for a thermostatically-controlled, air-conditioned, partitioned room: Numerical results and enhanced graphical presentation  

SciTech Connect

An index of local thermal comfort and pollutant distributions have been computed with the TEMPEST computer code, in a transient simulation of an air-conditioned enclosure with an incomplete partition. This complex three-dimensional air conditioning problem included forced ventilation through inlet veins, flow through a partition, remote return air vents, and infiltration source, a pollutant source, and a thermostatically controlled air conditioning system. Five forced ventilation schemes that varied in vent areas and face velocities were simulated. Thermal comfort was modeled as a three-dimensional scalar field dependent on the fluid velocity and temperature fields; where humidity activity levels, and clothing were considered constants. Pollutants transport was incorporated through an additional constituent diffusion equation. Six distinct graphic techniques for the visualization of the three-dimensional data fields of air velocity, temperature, and comfort index were tested. 4 refs., 7 figs., 1 tab.

Development of Refrigerant Change Indicator and Dirty Air Filter Sensor  

Science Conference Proceedings (OSTI)

The most common problems affecting residential and light commercial heating, ventilation, and air-conditioning (HVAC) systems are slow refrigerant leaks and dirty air filters. Equipment users are usually not aware of a problem until most of the refrigerant has escaped or the air filter is clogged with dirt. While a dirty air filter can be detected with a technology based on the air pressure differential across the filter, such as a ''whistling'' indicator, it is not easy to incorporate this technology into existing HVAC diagnostic equipment. Oak Ridge National Laboratory is developing a low-cost, nonintrusive refrigerant charge indicator and dirty air filter detection sensor. The sensors, based on temperature measurements, will be inexpensive and easy to incorporate into existing heat pumps and air conditioners. The refrigerant charge indicator is based on the fact that when refrigerant starts to leak, the evaporator coil temperature starts to drop and the level of liquid subcooling drops. When the coil temperature or liquid subcooling drops below a preset reading, a signal, such as a yellow warning light, can be activated to warn the equipment user that the system is undercharged. A further drop of coil temperature or liquid subcooling below another preset reading would trigger a second warning signal, such as a red warning light, to warn the equipment user that the unit now detects a leak and immediate action should be taken. The warning light cannot be turned off until it is re-set by a refrigeration repairman. To detect clogged air filters, two additional temperature sensors can be applied, one each across the evaporator. When the air filter is accumulating buildup, the temperature differential across the evaporator will increase because of the reduced airflow. When the temperature differential reaches a pre-set reading, a signal will be sent to the equipment user that the air filter needs to be changed. A traditional refrigerant charge indicator requires intrusion into the system to measure the refrigerant high-side and low-side pressures. Once the pressures are known, based on the equipment's refrigerant charging chart? or in most cases, based on the technician's experience? the refrigerant charging status is determined. However, there is a catch: by the time a refrigeration technician is called, most of the refrigerant has already escaped into the atmosphere. The new technology provides a real-time warning so that when, say, 20% of the refrigerant has leaked, the equipment users will be warned, even though the equipment is still functioning properly at rated capacity. Temperature sensors are becoming very accurate and very low in cost, compared with pressure sensors. Using temperature sensors to detect refrigerant charge status is inherently nonintrusive, inexpensive, and accurate. With the addition of two temperature sensors for detecting dirty air filters, the capability of the diagnostic equipment is further enhanced with very little added cost. This report provides laboratory test data on the change of indoor coil refrigerant temperature and subcooling as a function of refrigerant charge for a 2-ton split heat pump system. The data can be used in designing the indicators for refrigerant loss and dirty air filter sensors.

Thin Air Breathing  

NLE Websites -- All DOE Office Websites (Extended Search)

Thin Air Breathing Thin Air Breathing Name: Amy Location: N/A Country: N/A Date: N/A Question: Why is it hard to breathe in thin air? What health dangers do mountain climbers face at high altitudes? Replies: Among the obvious dangers of losing ones footing, the oxygen available in the air is considerable less at higher altitudes. If I recall correctly, 21% of the atmosphere at standard temperature and pressure at sea level is composed of oxygen. This is less at higher altitudes. One can lose consciousness and even die in an oxygen deficient environment with changes from oxygen content to lower than 19.5%. This can unfortunate effect can occur within minutes. Dr. Myron The air is not really thin at high altitudes. The problem is that air pressure is lower. As altitude increases, air pressure decreases. In order for your lungs to fill with air, the air pressure in your lungs has to be less than the pressure of the air outside your lungs. Air moves from areas of higher pressure to lower pressure. As your diaphragm (the muscle that separates your chest cavity from your abdominal cavity) moves downward, the size of your chest cavity increases. This decreases the pressure in your chest and air flows in. When the diaphragm is up, it puts pressure on the chest cavity and the pressure in the lungs is greater than outside the lungs. Air flows out. This is an example of Boyle's Law. The movement of the diaphragm is controlled by the brainstem. Anyway-the reason that it is harder for some people to breathe at higher altitudes is that the air pressure differences aren't as great between the inside of the lungs and outside.

Multi-electrode double layer capacitor having single electrolyte seal and aluminum-impregnated carbon cloth electrodes  

DOE Patents (OSTI)

A single cell, multi-electrode high performance double layer capacitor includes first and second flat stacks of electrodes adapted to be housed in a closeable two-part capacitor case which includes only a single electrolyte seal. Each electrode stack has a plurality of electrodes connected in parallel, with the electrodes of one stack being interleaved with the electrodes of the other stack to form an interleaved stack, and with the electrodes of each stack being electrically connected to respective capacitor terminals. A porous separator sleeve is inserted over the electrodes of one stack before interleaving to prevent electrical shorts between the electrodes. The electrodes are made by folding a compressible, low resistance, aluminum-impregnated carbon cloth, made from activated carbon fibers, around a current collector foil, with a tab of the foils of each electrode of each stack being connected in parallel and connected to the respective capacitor terminal. The height of the interleaved stack is somewhat greater than the inside height of the closed capacitor case, thereby requiring compression of the interleaved electrode stack when placed inside of the case, and thereby maintaining the interleaved electrode stack under modest constant pressure. The closed capacitor case is filled with an electrolytic solution and sealed. A preferred electrolytic solution is made by dissolving an appropriate salt into acetonitrile (CH.sub.3 CN). In one embodiment, the two parts of the capacitor case are conductive and function as the capacitor terminals.

NREL's Energy-Saving Technology for Air Conditioning Cuts Peak Power Loads Without Using Harmful Refrigerants (Fact Sheet)  

SciTech Connect

This fact sheet describes how the DEVAP air conditioner was invented, explains how the technology works, and why it won an R&D 100 Award. Desiccant-enhanced evaporative (DEVAP) air-conditioning will provide superior comfort for commercial buildings in any climate at a small fraction of the electricity costs of conventional air-conditioning equipment, releasing far less carbon dioxide and cutting costly peak electrical demand by an estimated 80%. Air conditioning currently consumes about 15% of the electricity generated in the United States and is a major contributor to peak electrical demand on hot summer days, which can lead to escalating power costs, brownouts, and rolling blackouts. DEVAP employs an innovative combination of air-cooling technologies to reduce energy use by up to 81%. DEVAP also shifts most of the energy needs to thermal energy sources, reducing annual electricity use by up to 90%. In doing so, DEVAP is estimated to cut peak electrical demand by nearly 80% in all climates. Widespread use of this cooling cycle would dramatically cut peak electrical loads throughout the country, saving billions of dollars in investments and operating costs for our nation's electrical utilities. Water is already used as a refrigerant in evaporative coolers, a common and widely used energy-saving technology for arid regions. The technology cools incoming hot, dry air by evaporating water into it. The energy absorbed by the water as it evaporates, known as the latent heat of vaporization, cools the air while humidifying it. However, evaporative coolers only function when the air is dry, and they deliver humid air that can lower the comfort level for building occupants. And even many dry climates like Phoenix, Arizona, have a humid season when evaporative cooling won't work well. DEVAP extends the applicability of evaporative cooling by first using a liquid desiccant-a water-absorbing material-to dry the air. The dry air is then passed to an indirect evaporative cooling stage, in which the incoming air is in thermal contact with a moistened surface that evaporates the water into a separate air stream. As the evaporation cools the moistened surface, it draws heat from the incoming air without adding humidity to it. A number of cooling cycles have been developed that employ indirect evaporative cooling, but DEVAP achieves a superior efficiency relative to its technological siblings.

Mitigating the Impacts of Uncontrolled Air Flow on Indoor Environmental Quality and Energy Demand in Non-Residential Buildings  

SciTech Connect

This multi-faceted study evaluated several aspects of uncontrolled air flows in commercial buildings in both Northern and Southern climates. Field data were collected from 25 small commercial buildings in New York State to understand baseline conditions for Northern buildings. Laboratory wall assembly testing was completed at Syracuse University to understand the impact of typical air leakage pathways on heat and moisture transport within wall assemblies for both Northern and Southern building applications. The experimental data from the laboratory tests were used to verify detailed heat and moisture (HAM) simulation models that could be used to evaluate a wider array of building applications and situations. Whole building testing at FSEC's Building Science Laboratory (BSL) systematically evaluated the energy and IAQ impacts of duct leakage with various attic and ceiling configurations. This systematic test carefully controlled all aspects of building performance to quantify the impact of duct leakage and unbalanced flow. The newest features of the EnergyPlus building simulation tool were used to model the combined impacts of duct leakage, ceiling leakage, unbalanced flows, and air conditioner performance. The experimental data provided the basis to validate the simulation model so it could be used to study the impact of duct leakage over a wide range of climates and applications. The overall objective of this project was to transfer work and knowledge that has been done on uncontrolled air flow in non-residential buildings in Florida to a national basis. This objective was implemented by means of four tasks: (1) Field testing and monitoring of uncontrolled air flow in a sample of New York buildings; (2) Detailed wall assembly laboratory measurements and modeling; (3) Whole building experiments and simulation of uncontrolled air flows; and (4) Develop and implement training on uncontrolled air flows for Practitioners in New York State.

Proposal for a Vehicle Level Test Procedure to Measure Air Conditioning Fuel Use  

SciTech Connect

The air-conditioning (A/C) compressor load significantly impacts the fuel economy of conventional vehicles and the fuel use/range of plug-in hybrid electric vehicles (PHEV). A National Renewable Energy Laboratory (NREL) vehicle performance analysis shows the operation of the air conditioner reduces the charge depletion range of a 40-mile range PHEV from 18% to 30% in a worst case hot environment. Designing for air conditioning electrical loads impacts PHEV and electric vehicle (EV) energy storage system size and cost. While automobile manufacturers have climate control procedures to assess A/C performance, and the U.S. EPA has the SCO3 drive cycle to measure indirect A/C emissions, there is no automotive industry consensus on a vehicle level A/C fuel use test procedure. With increasing attention on A/C fuel use due to increased regulatory activities and the development of PHEVs and EVs, a test procedure is needed to accurately assess the impact of climate control loads. A vehicle thermal soak period is recommended, with solar lamps that meet the SCO3 requirements or an alternative heating method such as portable electric heaters. After soaking, the vehicle is operated over repeated drive cycles or at a constant speed until steady-state cabin air temperature is attained. With this method, the cooldown and steady-state A/C fuel use are measured. This method can be run at either different ambient temperatures to provide data for the GREEN-MAC-LCCP model temperature bins or at a single representative ambient temperature. Vehicles with automatic climate systems are allowed to control as designed, while vehicles with manual climate systems are adjusted to approximate expected climate control settings. An A/C off test is also run for all drive profiles. This procedure measures approximate real-world A/C fuel use and assess the impact of thermal load reduction strategies.

Ambient Air Sampling During Quantum-dot Spray Deposition  

Science Conference Proceedings (OSTI)

Ambient air sampling for nano-size particle emissions was performed during spot spray coating operations with a Sono-Tek Exactacoat Benchtop system (ECB). The ECB consisted of the application equipment contained within an exhaust enclosure. The enclosure contained numerous small access openings, including an exhaust hook-up. Door access comprised most of the width and height of the front. The door itself was of the swing-out type. Two types of nanomaterials, Cadmium selenide (Cd-Se) quantum-dots (QDs) and Gold (Au) QDs, nominally 3.3 and 5 nm in diameter respectively, were applied during the evaluation. Median spray drop size was in the 20 to 60 micrometer size range.1 Surface coating tests were of short duration, on the order of one-half second per spray and ten spray applications between door openings. The enclosure was ventilated by connection to a high efficiency particulate aerosol (HEPA) filtered house exhaust system. The exhaust rate was nominally 80 ft3 per minute producing about 5 air changes per minute. Real time air monitoring with a scanning mobility particle size analyzer (SMPS ) with a size detection limit of 7 nm indicated a significant increase in the ambient air concentration upon early door opening. A handheld condensation particle counter (CPC) with a lower size limit of 10 nm did not record changes in the ambient background. This increase in the ambient was not observed when door opening was delayed for 2 minutes (~10 air changes). The ventilated enclosure controlled emissions except for cases of rapid door opening before the overspray could be removed by the exhaust. A time delay sufficient to provide 10 enclosure air changes (a concentration reduction of more than 99.99 %) before door opening prevented the release of aerosol particles in any size.2 Scanning-transmission electron microscopy (STEM) and atomic force microscopy (AFM) demonstrated the presence of agglomerates in the surfaces of the spray applied deposition. A filtered air sample of the enclosure overspray examined by AFM also demonstrated the presence of agglomerates for the Au QDs. The AFM system was not able to resolve individual QDs as was the STEM. Chemical fingerprinting of the QDs with STEM/EDS (energy dispersive spectroscopy) was performed for the Cd-Se surface deposition, but not the aerosol. Both STEM and AFM background characterization by morphology and chemical fingerprinting were performed throughout the laboratory for a period of about one year. Outdoor sources were primarily biological, combustion fume, salt and other crustal particles. Indoor sources were primarily paper/clothing fibers, spray-on insulation fragments, fiber glass, and human skin cells.

Meeting the Air Leakage  

NLE Websites -- All DOE Office Websites (Extended Search)

Meeting the Air Leakage Meeting the Air Leakage Requirements of the 2012 IECC The U.S. Department of Energy (DOE) recognizes the enormous potential that exists for improving the energy efficiency, safety and comfort of homes. The newest edition of the International Energy Conservation Code ® (IECC) (2012) sets the bar higher for energy efficiency, and new air sealing requirements are one of the key new provisions. This guide is a resource for understanding the new air leakage requirements in the 2012 IECC and suggestions on how these new measures can be met. It also provides information from Building America's Air Sealing Guide, Best Practices and case studies on homes that are currently meeting the provisions. The 2012 IECC and a few International Residential Code (IRC) requirements are referenced throughout the guide.
