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.

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.

Experimental analysis of a window air conditioner with R-22 and zeotropic mixture of R-32/125/134a  

SciTech Connect

This study is the result of the cooperative research and development agreement (CRADA) between Oak Ridge National Laboratory and E.I. Du Pont De Nemours and Company, Inc., (CRADA No. 92-0161) for testing the use of heat exchangers as the evaporator and condenser in an air-conditioning rig. Heat exchangers at typical realistic operating conditions were tested with R-22 and with its potential replacement, a ternary mixture of R-32(30%)/R-125(10%)/R-134a(60%). A test rig was built that provided for operation of the low-temperature exchanger (evaporator) with flooded coils. The test results indicated that the performance of the evaporator heat exchanger using ternary mixture, in terms of cooling capacity, would be around 7.4% less than the performance using R-22. The cooling capacity for both refrigerants improved with flooded evaporator operation by 8.6% for R-22 and by 15% for ternary mixture. Compared with R-22 operation, operation with ternary mixture results in slightly higher compressor discharge pressure, lower compressor discharge temperature, slightly lower compressor power consumption, and a higher compressor high-low pressure ratio. Temperature glide for ternary mixture, for both evaporator and condenser, was clearly evident, but not as pronounced as expected because of the pressure drop (and thus the temperature drop) along the coils. Further improvement of the performance of ternary mixture is possible if the evaporator is arranged in a counter-cross-flow configuration to take advantage of the temperature glide. Current evaporator designs are mostly concurrent-cross-flow, which is more appropriate for single-component refrigerants or azeotropic refrigerant mixtures.

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.

An automobile air conditioner design model  

SciTech Connect

A computer program has been developed to predict the steady-state performance of vapor compression automobile air conditioners and heat pumps. The code is based on the residential heat pump model developed at the Oak Ridge National Laboratory (ORNL). Most calculations are based on fundamental physical principles, in conjunction with generalized correlations available in the research literature. Automobile air conditioning components that can be specified as input to the program include open and hermetic compressors; finned tube condensers; finned tube and plate-fin style evaporators; thermostatic expansion valves (TXV), capillary tube, and short tube expansion devices; refrigerant mass; and evaporator pressure regulator and all interconnecting tubing. Pressure drop, heat transfer rates, and latent capacity ratio for the new plate-fin evaporator submodel are shown to agree well with laboratory data. The program can be used with a variety of refrigerants, including R-134a.

The performance of an optimized thermoacoustic air conditioner  

Science Journals Connector (OSTI)

Up to 25 thermoacoustic cooler design parameters were optimized to provide high COP predictions in selected air conditioning applications. Capacities ranging between 300 and 1500 W were considered. Two different configurations were investigated: (1) a single stack with a Helmholtz resonator termination and (2) two drivers and two stacks. The optimization scheme utilized the Simplex algorithm and the analysis was performed by DELTAE coupled with an original heat exchanger modeling tool which incorporated conventional straight fin analysis and semiempirical flow correlations. Various requirements were imposed for the external cooling and heat rejection temperatures ranging between 270 and 287 K on the cold side and between 310 and 320 K on the hot side. Finned tube heat exchangers with water as the secondary fluid were considered. The predicted values of COP were greater than 3.8 (0.36 relative to the Carnot value) for an application analogous to a small window air conditioner. The performance and characteristics of the two different configurations were compared and the loss distribution in each case was calculated. Furthermore the impact of various constraints was examined. The performance predictions are encouraging and suggest that thermoacoustic air conditioning may be a viable proposition.

Payne, and Laura Van Wie McGrory Conference Name Proceedings from the 2000 ACEEE Summer Study on Energy Efficiency in Buildings Volume 10 Pagination 217-226 Date Published 01/2000 Abstract The energy efficiency ofmany products has increased markedly over the past decade. 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.

EER, COP, and the second law efficiency for air conditioners  

Science Journals Connector (OSTI)

It is pointed out that there is a close relationship between the energy efficiency ratio (EER) of an air conditioner unit and the coefficient of performance (COP) of its refrigeration cycle. This connection helps to bridge the gap between pure thermodynamics and practical energy?related problems. In this spirit two other efficiency parameters the total COP and total EER measured relative to the energy extracted by a primary energy source (e.g. a fossil fuel) are defined. A comparison of the actual total COP (or total EER) relative to its maximum allowed value consistent with the second law of thermodynamics leads to an estimate for air conditioners of the recently proposed s e c o n d l a w e f f i c i e n c y.

Effects of Air Conditioner Use on Real-World Fuel Economy  

SciTech Connect

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

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.

Swimming pools as heat sinks for air conditioners: California feasibility analysis  

Science Journals Connector (OSTI)

Earlier studies used field testing of swimming pool temperatures to validate a mathematical model for predicting the temperature of an unheated pool. Combining those results with manufacturers data on the performance of vapor-compression air conditioners as a function of heat rejection temperature, the analyses in the paper suggest that rejecting air conditioning heat to a swimming pool can save approximately 2530% of single-family residential cooling electricity use and reduce cooling electricity demand during peak conditions by 3035%, as compared to using the same compressor to reject the heat to ambient air. The savings is expected to vary depending on the severity of the climate, as well as the pool temperature experienced during the summer. The original model was refined so as to accommodate air-conditioner heat rejection to predict pool temperatures based on weather data, pool size, shading of the pool, and air-conditioner heat rejection to the pool. The results of an experimental validation of the augmented pool thermal model are presented here. In addition, the model of a pool-coupled air conditioning system was used to develop a design tool for determining the pool size needed to absorb realistic heat rejection from air conditioners in various California climate zones.

Technical and economic analysis of energy efficiency of Chinese room air conditioners  

SciTech Connect

China has experienced tremendous growth in the production and sales of room air conditioners over the last decade. Although minimum room air conditioner energy efficiency standards have been in effect since 1989, no efforts were made during most of the 1990's to update the standard to be more reflective of current market conditions. In 1999, China's State Bureau of Technical Supervision (SBTS) included in their annual plan the development and revision of the 1989 room air conditioner standard, and experts from SBTS worked together with LBNL to analyze the new standards. Based on the engineering and life cycle-cost analyses performed, the most predominant type of room air conditioner in the Chinese market (split-type with a cooling capacity between 2500 and 4500 W (8500 Btu/h and 15,300Btu/h)) can have its efficiency increased cost-effectively to an energy efficiency ratio (EER) of 2.92 W/W (9.9 Btu/hr/W). If an EER standard of 2.92 W/W became effective in 2001, Chinese consumers would be estimated to save over 3.5 billion Yuan (420 million U.S. dollars) over the period of 2001-2020. Carbon emissions over the same period would be reduced by approximately 12 million metric tonnes.

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.

Windows Windows Tips: Windows June 18, 2012 - 9:43am Addthis Tips: Windows Windows can be one of your home's most attractive features. Windows provide views, daylighting, ventilation, and heat from the sun in the winter. Unfortunately, they can also account for 10% to 25% of your heating bill by letting heat out. During the summer, your air conditioner must work harder to cool hot air from sunny windows. Install ENERGY STAR®-qualified windows and use curtains and shade to give your air conditioner and energy bill a break. If your home has single-pane windows, consider replacing them with double-pane windows with high-performance glass-low-e or spectrally selective coatings.

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 200. The Courts ruling, which struck down a May 2002 rollback of the 2001 standard to a 12 Seasonal Energy Efficiency Ratio (SEER) mandates that all new central air conditioners and heat pumps meet a 13 SEER standard by January 2006, requiring a 30% increase in efficiency relative to current law. The Annual Energy Outlook 2005 reference case incorporates the 13 SEER standard as mandated by the Courts ruling.

Energy Impacts of Oversized Residential Air Conditioners -- Simulation Study of Retrofit Sequence Impacts  

SciTech Connect

This research addresses the question of what are the energy consequences for oversizing of an air conditioner in a home. Conventional wisdom holds that oversizing the AC results in significant energy penalties. However, the reason for this was shown to be due to crankcase heaters and not due to cycling performance of the AC, and is only valid for a particular set of assumptions. Adding or removing individual characteristics, such as ducts or crankcase heaters, can have measurable impacts on energy use. However, with all other home characteristics held constant, oversizing the AC generally has a small effect on cooling energy use, even if the cycling performance of the unit is poor. The relevant aspects of air conditioner modeling are discussed to illustrate the effects of the cycling loss coefficient, Cd, capacity, climate, ducts and parasitic losses such as crankcase heaters. A case study of a typical 1960's vintage home demonstrates results in the context of whole building simulations using EnergyPlus.

SciTech Connect

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.

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.

Performance characteristics of a turbo expander substituted for expansion valve on air-conditioner  

Science Journals Connector (OSTI)

An experimental study is conducted on a small turbo expander which could be applied to the expansion process in place of expansion valves in refrigerator or air-conditioner to improve the cycle efficiency by recovering energy from the throttling process. The operating gas is \\{HFC134a\\} and the maximum cooling capacity of experiment apparatus is 32.7kW. Four different turbo expanders are tested to find the performance characteristics of the turbo expander when they operate at a low partial admission rate. The partial admission rate is 1.70% or 2.37, and expanders are operated in the supersonic flow. In the experiment, pressure and temperature are measured at 10 different locations in the experimental apparatus. In addition to these measurements, output power at the turbo expander is measured through a generator installed on a rotor shaft with the rotational speed. Performance data of the turbo expander are obtained at many part load operations by adjusting the output power of the generator. A maximum of 15.8% total-to-static efficiency is obtained when the pressure ratio and the partial admission ratio are 2.37 and 1.70%, respectively. Experimental results show that the optimal velocity ratio decreases when the pressure ratio is decreased, and peak efficiencies, which are obtained at locally maximized efficiency depending on the operating condition, vary linearly against the subcooling temperature or the pressure ratio.

In the experiment, pressure and temperature are measured at 10 different locations in the experimental apparatus. In addition to these measurements, output power at the turbo expander is measured through a generator installed on a rotor shaft with the rotational speed. Performance data of the turbo expander are obtained at many part load operations by adjusting the output power of the generator. A maximum of 15.8% total-to-static efficiency is obtained when the pressure ratio and the partial admission ratio are 2.37 and 1.70%, respectively. Experimental results show that the optimal velocity ratio decreases when the pressure ratio is decreased, and peak efficiencies, which are obtained at locally maximized efficiency depending on the operating condition, vary linearly against the subcooling temperature or the pressure ratio.

Swimming pools as heat sinks for air conditioners: Model design and experimental validation for natural thermal behavior of the pool  

Science Journals Connector (OSTI)

Swimming pools as thermal sinks for air conditioners could save approximately 40% on peak cooling power and 30% of overall cooling energy, compared to standard residential air conditioning. Heat dissipation from pools in semi-arid climates with large diurnal temperature shifts is such that pool heating and space cooling may occur concurrently; in which case heat rejected from cooling equipment could directly displace pool heating energy, while also improving space cooling efficiency. The performance of such a system relies on the natural temperature regulation of swimming pools governed by evaporative and convective heat exchange with the air, radiative heat exchange with the sky, and conductive heat exchange with the ground. This paper describes and validates a model that uses meteorological data to accurately predict the hourly temperature of a swimming pool to within 1.1C maximum error over the period of observation. A thorough review of literature guided our choice of the most appropriate set of equations to describe the natural mass and energy exchange between a swimming pool and the environment. Monitoring of a pool in Davis, CA, was used to confirm the resulting simulations. Comparison of predicted and observed pool temperature for all hours over a 56 day experimental period shows an R-squared relatedness of 0.967.

Local Voltage Support from Distributed Energy Resources to Prevent Air Conditioner Motor Stalling  

SciTech Connect

Microgrid voltage collapse often happens when there is a high percentage of low inertia air-conditioning (AC) motors in the power systems. The stalling of the AC motors results in Fault Induced Delayed Voltage Recovery (FIDVR). A hybrid load model including typical building loads, AC motor loads, and other induction motor loads is built to simulate the motoring stalling phenomena. Furthermore, distributed energy resources (DE) with local voltage support capability are utilized to boost the local bus voltage during a fault, and prevent the motor stalling. The simulation results are presented. The analysis of the simulation results show that local voltage support from multiple DEs can effectively and economically solve the microgrid voltage collapse problem.

Measuring Performance: Air Leakage (AL) Measuring Performance: Air Leakage (AL) Is my window leaking air? The Air Leakage (AL) rating pertains to leakage through the window assembly itself. Air infiltration can also occur around the frame of the window due to poor installation or poor maintenance of existing window systems. Make sure windows are properly installed and maintained (caulking and weatherstripping). Cold glass can create uncomfortable drafts as air next to the window is cooled and drops to the floor. This is not a result of air leaking through or around the window assembly but from a convective loop created when next to a window is cooled and drops to the floor. This air movement can be avoided by installing high-performance windows. Heat loss and gain occur by infiltration through cracks in the window

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.

Window Technologies: Operator Types Window Technologies: Operator Types Window Sash Operation When you select a window, there are numerous operating types to consider. Traditional operable window types include the projected or hinged types such as casement, awning, and hopper, and the sliding types such as double- and single-hung and horizontal sliding. In addition, the window market includes fixed windows, storm windows, sliding and swinging patio doors, skylights and roof windows, and window systems that can be added to a house to create bay or bow windows, miniature greenhouses, or full sun rooms. Looking for information on skylights? More information on skylights, light tubes, and their installation can be found here. Casement Casement windows are hinged at the sides. Hinged windows such as casements generally have lower air leakage rates than sliding windows from the same manufacturer because the sash closes by pressing against the frame. Casement windows project outward, providing significantly better ventilation than sliders of equal size. Because the sash protrudes from the plane of the wall, it can be controlled to catch passing breezes, but screens must be placed on the interior side. Virtually the entire casement window area can be opened, while sliders are limited to less than half of the window area. Casement

Understanding Windows Understanding Windows Benefits of Energy Efficient Windows The purpose for windows is to provide natural light, natural ventilation, and views to the outside. The benefits of high performance windows allows for Energy & Cost Savings, Improved Comfort, Less Condensation, Increased Light & View, Reduced Fading, and Lower HVAC Costs. Benefits of Energy Efficient Windows Design Considerations Windows are a complex and interesting element in residential design. New window products and technologies have changed the performance of windows in a radical way. Issues such as climate, orientation, shading, and window area all effect the energy performance, but human factor issues such as access to fresh air, daylight, and natural views impact the comfort of a home.

SYSTEM REQUIREMENTS GET A COPY DOCUMENTATION KNOWLEDGE BASE Overview Today's energy-efficient windows can dramatically lower the heating and cooling costs associated with windows while increasing occupant comfort and minimizing window surface condensation problems. However, consumers are often confused about how to pick the most efficient window for a residence. Product information typically offers window properties: U-factors or R-values, Solar Heat Gain Coefficients or Shading Coefficients, and air leakage rates. However, the relative importance of these properties depends on site- and building-specific conditions. Furthermore, these properties are based on static evaluation conditions that are very different from the real situation a window will be used in.

Window annual energy rating systems: What they tell us about residential window design and selection  

SciTech Connect

Residential window annual energy rating systems have been developed in Canada and the US. These systems combine window properties of solar heat gain coefficient, U-factor, and air-infiltration into a single number representative of the energy performance for each of the heating season and the cooling season. These systems provide a simple means for designers to select the best energy performing window for low-rise residential buildings over the heating and cooling seasons. The two systems, which rank windows in the same order, give different information on optimum window design and selection than just a simple U-factor comparison. These systems show the importance of a high window SHGC in cold climates and a low SHGC in hot climates. The impact of window air infiltration is surprisingly small relative to the solar heat gain and heat conduction losses.

High Energy Efficiency Air Conditioning  

SciTech Connect

This project determined the performance of a new high efficiency refrigerant, Ikon B, in a residential air conditioner designed to use R-22. The refrigerant R-22, used in residential and small commercial air conditioners, is being phased out of production in developed countries beginning this year because of concerns regarding its ozone depletion potential. Although a replacement refrigerant, R-410A, is available, it operates at much higher pressure than R-22 and requires new equipment. R-22 air conditioners will continue to be in use for many years to come. Air conditioning is a large part of expensive summer peak power use in many parts of the U.S. Previous testing and computer simulations of Ikon B indicated that it would have 20 - 25% higher coefficient of performance (COP, the amount of cooling obtained per energy used) than R-22 in an air-cooled air conditioner. In this project, a typical new R-22 residential air conditioner was obtained, installed in a large environmental chamber, instrumented, and run both with its original charge of R-22 and then with Ikon B. In the environmental chamber, controlled temperature and humidity could be maintained to obtain repeatable and comparable energy use results. Tests with Ikon B included runs with and without a power controller, and an extended run for several months with subsequent analyses to check compatibility of Ikon B with the air conditioner materials and lubricant. Baseline energy use of the air conditioner with its original R-22 charge was measured at 90 deg F and 100 deg F. After changeover to Ikon B and a larger expansion orifice, energy use was measured at 90 deg F and 100 deg F. Ikon B proved to have about 19% higher COP at 90 deg F and about 26% higher COP at 100 deg F versus R-22. Ikon B had about 20% lower cooling capacity at 90 deg F and about 17% lower cooling capacity at 100 deg F versus R-22 in this system. All results over multiple runs were within 1% relative standard deviation (RSD). All of these values agree well with previous results and computer simulations of Ikon B performance versus R-22. The lower cooling capacity of Ikon B is not a concern unless a particular air conditioner is near its maximum cooling capacity in application. Typically, oversized A/C systems are installed by contractors to cover contingencies. In the extended run with Ikon B, which lasted about 4.5 months at 100 deg F ambient temperature and 68% compressor on time, the air conditioner performed well with no significant loss of energy efficiency. Post-run analysis of the refrigerant, compressor lubricant oil, compressor, compressor outlet tubing, and the filter/dryer showed minor effects but nothing that was considered significant. The project was very successful. All objectives were achieved, and the performance of Ikon B indicates that it can easily be retrofitted into R-22 air conditioners to give 15 - 20% energy savings and a 1 - 3 year payback of retrofit costs depending on location and use. Ikon B has the potential to be a successful commercial product.

Energy performance of a dual airflow window under different climates  

Science Journals Connector (OSTI)

Ventilated windows have shown great potential in conserving energy in buildings and provide fresh air to improve indoor air quality. This paper reports our effort to use EnergyPlus to simulate the energy performance of a dual airflow window under different climates. Our investigation first developed a network model to account for the two-dimensional heat transfer in the window system and implemented it in EnergyPlus. The two-dimensional assumption and the modified EnergyPlus program were validated by the measured temperatures of the window and the energy demand of a test cell with the window under actual weather conditions. Then EnergyPlus was applied to analyze energy performance of a small apartment installed with the dual airflow windows in five different climate zones in China. The energy used by the apartment with blinds windows and low-e windows was also calculated for comparison. The dual airflow window can reduce heating energy of the apartment, especially in cold climate. The cooling energy reduction by the window was less important than that by shading solar radiation. The dual airflow window is recommended for colder climate. If improving air quality is a major consideration for a building, the window can be used in any climate.

Mobile Window Thermal Test

Mobile Window Thermal Test (MoWiTT) Facility Mobile Window Thermal Test (MoWiTT) Facility winter.jpg (469135 bytes) The window has come a long way since the days when it was a single pane of glass in a wood frame. Low-emissivity windows were designed to help buildings retain some of the energy that would have leaked out of less efficient windows. Designing efficient window-and-frame systems is one strategy for reducing the energy use of buildings. But the net energy flowing through a window is a combination of temperature- driven thermal flows and transmission of incident solar energy, both of which vary with time. U-factor and solar heat gain coefficient (SHGC), the window properties that control these flows, depend partly on ambient conditions. Window energy flows can affect how much energy a building uses, depending on when the window flows are available to help meet other energy demands within the building, and when they are adverse, adding to building energy use. This leads to a second strategy for reducing building energy use: using the beneficial solar gain available through a window, either for winter heating or for daylighting, while minimizing adverse flows.

Highly Insulating Window Technology  

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

Window Technology Window Technology Temperature differentials across a window, particularly with cold exterior environments in residential buildings, can lead to significant energy losses. Currently available low-emissivity coatings, gas-fills, and insulating frames provide significant energy savings over typical single or double glazed products. The EWC website provides information on how double glazed low-e gas-filled windows work as well as information on commercially available superwindows (three layer, multiple low-e coatings, high performance gas-fills). The next generation of highly insulating window systems will benefit from incremental improvements being made to current components (i.e. more insulating spacers and frame materials/designs, low-e coatings with improved performance properties). LBNL uses its experimental facilities and software tools to collaborate with window and glass industry representatives to better understand the impacts of new components on overall product performance.

Glass Glass Vacuum-insulated Glass Vacuum-insulated glazing units are made up of 2 panes of glass with a very small air space. The air space contains spacers which help maintain the separation between the panes. Most of the emerging glass technologies are available or nearly on the market. These include insulation-filled and evacuated glazings to improve heat transfer by lowering U-factors. Evacuated Windows The most thermally efficient gas fill would be no gas at all-a vacuum. The window industry is pursuing the development of vacuum-insulated glass (VIG) for use in window units in which the space between the panes is evacuated. If the vacuum pressure is low enough, there would be no conductive or convective heat exchange between the panes of glass, thus lowering the U-factor. A vacuum glazing must have a good low-E coating to

Improved Comfort Improved Comfort Comfort High performance windows with new glazing technologies not only reduce energy costs but make homes more comfortable as well. During cold weather, exterior temperatures drive interior glass surface temperatures down below the room air temperature; how low the glass temperature drops depends on the window's insulating quality. If people are exposed to the effects of a cold surface, they can experience significant radiant heat loss to that cold surface and they feel uncomfortable, even if the room air temperature is comfortable. When the interior glass surface temperature is 52˚F or less, it is most likely that there will be discomfort. During warm weather, solar radiation can cause discomfort. Just as people turn up the heat to compensate for cold windows in cold weather, they may use

Highly Insulating Windows - Cost  

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

Cost Cost The following is an estimate of the cost effective incremental cost of highly-insulating windows (U-factor=0.20 Btu/hr-ft2-F) compared to regular ENERGY STAR windows (U-factor 0.35 Btu/hr-ft2-F). Energy savings from lower U-factors were simulated with RESFEN over an assumed useful window life of 25 years. To determine the maximum incremental cost at which highly-insulating windows would still be cost-effective, we used a formula used by many utility companies to calculate the cost of saved energy from energy efficiency programs, based on the programs' cost and savings. We turned this formula around so that the cost of saved energy equals the present energy prices in the studied locations, whereas the program cost (the incremental cost of the windows) is the dependent variable.

Plasma window characterization  

SciTech Connect

Parameters of an arc Ar plasma discharge used as a plasma window with a discharge current of {approx}50 A and a voltage of {approx}58 V are presented. It is shown that this arc discharge allows one to decrease the pressure at the low pressure end of the plasma window almost 380 times using relatively low pumping at the low pressure end of the plasma window. Calculations of the plasma parameters and their spatial distribution using a simple wall-stabilized arc model showed a satisfactory agreement with the experimentally obtained data. It is shown that a significant decrease in gas flow through the plasma window occurs due to the increase in plasma viscosity. An improvement of the plasma window ignition and some of its design aspects are described as well.

Field Evaluation of Windows  

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

Evaluation of Windows Evaluation of Windows Last Updated: 10/20/2009 Various tools can be used to evaluate windows in the field. Unless a new window still has the NFRC label attached to it, it is nearly impossible to determine by sight what the thermal and optical performance of a window is. These tools can provide information, such as low-e coating, gap width and gas fill, that can be used to approximate the performance of a window. Solar gain and Low-e detector This device can be used to determine if a low-e coating is present in the window, what type of coating it is, and where it is located. The type of low-e coating will indicate the amount of solar gain that is admitted through the coating. Readings can be "low", "medium" or "high". The device will also indicate on which glass surface the low-e coating is in relation to the position of the device. Limitations: Only works on glass of 1/8" (3 mm) or thinner. Cost: around $350 from EDTM.com

Section 38 - HVAC (Heating, Ventilation, Air Conditioning)  

Science Journals Connector (OSTI)

The term HVAC is an acronym for Heating, Ventilation (and) Air Conditioning, the industry term for any of various efforts to control conditions in a building or other enclosed area to improve comfort and efficiency. A closely related section is Refrigeration, which follows this one. Some contemporary HVAC techniques have ancient roots. Early forms of central heating and solar home heating were in use in Rome in the first century A.D. The earliest use of glass in windows (as opposed to a covering of wood, cloth, or hide, or simply an opening) is also attributed to the Romans at this same time. The first known use of solar-oriented building design in North America dates back to about the year 1050; i.e., the cliff dwellings built by the Anasazi (Ancient Pueblo) people of the Colorado Plateau area. Geothermal district heating was employed as early as the 1300s, in the Auvergne region of southern France. The foundation for modern central heating was established in the 1700s, first in England and then in France. The 1800s saw significant advances in the use of water heaters, especially the first automatic storage water heater (Edwin Ruud, 1889) and the first commercial solar water heater (Clarence Kemp, 1891). In comparison with heating, cooling technology was late in developing. The first successful method of producing ice occurred in 1851, and it was not until 1902 that Willis Haviland Carrier designed the first industrial air-conditioning system. His Carrier Air Conditioning Corporation would go on to develop air-conditioning systems for stores and theaters (1924) and for residential buildings (1928). Carrier remains the global leader in air conditioner production. The first air-conditioned automobile was produced by Packard in 1939. Recent entries in this section emphasize the use of alternative energy sources in heating and cooling, such as solar, photovoltaic, geothermal, and fuel cells. These advances include the ground-source heat pump, the Trombe wall, the heat pipe, and the PV/thermal hybrid system.

High Performance Window Retrofit  

SciTech Connect

The US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) and Traco partnered to develop high-performance windows for commercial building that are cost-effective. The main performance requirement for these windows was that they needed to have an R-value of at least 5 ft2 F h/Btu. This project seeks to quantify the potential energy savings from installing these windows in commercial buildings that are at least 20 years old. To this end, we are conducting evaluations at a two-story test facility that is representative of a commercial building from the 1980s, and are gathering measurements on the performance of its windows before and after double-pane, clear-glazed units are upgraded with R5 windows. Additionally, we will use these data to calibrate EnergyPlus models that we will allow us to extrapolate results to other climates. Findings from this project will provide empirical data on the benefits from high-performance windows, which will help promote their adoption in new and existing commercial buildings. This report describes the experimental setup, and includes some of the field and simulation results.

Low-E Coatings Low-E Coatings Low-E Center-of-glass values of double pane units with and without low-E coatings. When heat or light energy is absorbed by glass, it is either convected away by moving air or reradiated by the glass surface. The ability of a material to radiate energy is called its emissivity. All materials, including windows, emit (or radiate) heat in the form of long-wave, far-infrared energy depending on their temperature. This emission of radiant heat is one of the important components of heat transfer for a window. Thus reducing the window's emittance can greatly improve its insulating properties. Standard clear glass has an emittance of 0.84 over the long-wave portion of the spectrum, meaning that it emits 84% of the energy possible for an object at its temperature. It also means that 84% of the long-wave

Frames Frames Research performed at the Norwegian University of Science and Technology and LBNL has identified various highly insulating frame solutions. A report was released in 2007 describing some of these frames. This document reports the findings of a market and research review related to state-of-the-art highly insulating window frames. The market review focuses on window frames that satisfy the Passivhaus requirements (window U-value less or equal to 0.8 W/m2K ), while other examples are also given in order to show the variety of materials and solutions that may be used for constructing window frames with a low thermal transmittance (U-value). The market search shows that several combinations of materials are used in order to obtain window frames with a low U-value. The most common insulating material seems to be Polyurethane (PUR), which is used together with most of the common structural materials such as wood, aluminum, and PVC.

Vacuum Glazing Modeling Vacuum Glazing Modeling It is now possible to model vacuum glazing in WINDOW 7. The first step is to define a new vacuum "gap" in the "Gap Library" (formerly the Gas Library). Then that vacuum gap is used in a glazing system to calculate the thermal characteristics of the glazing system with a vacuum gap. Gap Library The Gas Library has been renamed the Gap Library. To define a vacuum gap, check the "Vacuum" checkbox (this is only available for single gases, not gas mixtures). When this box is checked, new input variables will appear, including the vacuum pressure, the specific heat ratio and molecular weight of the vacuum gas. It is also necessary to define a pillar system for the vacuum gap. Pillar Definition Double click the double arrow to the right of the Pillar Definition pulldown to define a new pillar system. Define the shape and dimensions of the pillar system.

Windows, Skylights, and Doors Research Windows, Skylights, and Doors Research The Emerging Technology team conducts research into technologies related to windows, skylights, and doors. These technologies can decrease energy demands, save money, and improve occupant thermal comfort. By working with industry partners, researchers, and other stakeholders, the U.S. Department of Energy also seeks to improve the availability of these products in the market. Research in windows, skylights, and doors includes: Daylighting and Shading Photo of a wall of windows with shades built over them to block out the noon sun. Daylighting and shading technologies alter the way that natural light affects a building, either by allowing more of it in (to light a room) or by preventing it from coming in. These technologies are important in that they allow building operators and managers to lower a building's lighting energy needs, as well as reducing the energy used in heating, ventilation, and air conditioning (HVAC) systems.

Recent developments in orifice meter and flow conditioner research  

SciTech Connect

In 1969 concerns were raised regarding the validity of the orifice meter`s coefficient of discharge uncertainty. An effort to resolve these concerns resulted in an internationally supported research project which produced a new sharp-edged concentric orifice meter empirical database and coefficient of discharge equation. However, the new empirical database and coefficient of discharge equation did not account for all of the differences being encountered in orifice metering. And in 1986, as a derivative of the coefficient of discharge equation research, questions were raised regarding the influences of installation effects on the orifice meter`s coefficient of discharge. The 1986 EC research data indicated that the flow conditioner and straight pipe installation requirements of the flow measurement standards were inadequate to prevent biasing of the orifice meter`s coefficient of discharge by flow disturbances generated from upstream piping elements. Data generated from 1990 through 1993 by GRI sponsored SWRI and NIST research confirmed the original EC biasing and further identified differential pressure tap radial position sensitivity and velocity profile and swirl angle theory deficiencies. Current research is continuing to define installation effects influences and identify possible solutions.

21 - Life cycle assessment (LCA) of windows and window materials  

Science Journals Connector (OSTI)

Abstract: Windows are a significant component in sustainable buildings in both the impacts caused by their material life cycles and by their influence on the performance of a building over its service life. Life cycle assessment (LCA) studies have compared the impacts of different framing materials with mixed results. LCA has also been used to estimate the environmental payback of higher manufacturing impacts from producing better performing windows. Future sustainable window selection should make use of standardized LCA data for windows and utilize advanced technologies to optimize window performance.

A First-Generation Prototype Dynamic Residential Window A First-Generation Prototype Dynamic Residential Window Title A First-Generation Prototype Dynamic Residential Window Publication Type Report LBNL Report Number LBNL-56075 Year of Publication 2004 Authors Kohler, Christian, Howdy Goudey, and Dariush K. Arasteh Call Number LBNL-56075 Abstract We present the concept for a smart highly efficient dynamic window that maximizes solar heat gain during the heating season and minimizes solar heat gain during the cooling season in residential buildings. We describe a prototype dynamic window that relies on an internal shade, which deploys automatically in response to solar radiation and temperature. This prototype was built at Lawrence Berkeley National Laboratory from commercially available off-the-shelf components. It is a stand-alone, standard-size product, so it can be easily installed in place of standard window products. Our design shows promise for near-term commercialization. Improving thermal performance of this prototype by incorporating commercially available highly efficient glazing technologies could result in the first window that could be suitable for use in zero-energy homes. The units predictable deployment of shading could help capture energy savings that are not possible with manual shading. Installation of dynamically shaded windows in the field will allow researchers to better quantify the energy effects of shades, which could lead to increased efficiency in the sizing of heating, ventilation, and air conditioning equipment for residences.

Evaluation of a CFD-model for simulation of simplified flow conditioners  

SciTech Connect

Perforated plate flow conditioners are used to generate a fully developed turbulent flow profile upstream of an orifice meter. It is very time-consuming to measure the effect of a flow conditioner for different upstream flow profiles. Therefore a project is initiated to evaluate the performance of a computational fluid computer code for this purpose. If the code correctly predicts the flow characteristics downstream of more complex flow conditioners. In this study a k-{var_epsilon} CFD-model was used to predict the flow downstream of obstruction plates having one large or nine small holes. Both mean velocity, turbulent kinetic energy, k, and the dissipation rate of turbulent kinetic energy, {var_epsilon}, were calculated and compared against measured data. The results indicate that it is possible to predict the mean velocity well and that the accuracy of the predicted k and {var_epsilon} depends on the complexity of the flow.

Glazing Glazing Double-Glazed, Clear Glass This figure illustrates the performance of a typical double-glazed unit with two lites of clear glass. The inner and outer layers of glass are both clear and separated by an air gap. Double glazing, compared to single glazing, cuts heat loss in half due to the insulating air space between the glass layers. In addition to reducing the heat flow, a double-glazed unit with clear glass will allow the transmission of high visible light and high solar heat gain. Double Clear Center of Glass Properties Note: These values are for the center of glass only. They should only be used to compare the effect of different glazing types, not to compare total window products. Frame choice can drastically affect performance.

Study of thermoelectric technology for automobile air conditioning  

SciTech Connect

An analytical study was conducted to determine the feasibility of employing thermoelectric (TE) cooling technology in automobile air conditioners. The study addressed two key issues -- power requirements and availability of thermoelectric materials. In this paper, a mathematical model was developed to predict the performance of TE air conditioners and to analyze power consumption. Results show that the power required to deliver a cooling capacity of 4 kW (13,80 Btu/h) in a 38{degree}C (100{degree}F) environment will be 9.5 kW electric. Current TE modules suitable for air conditioning are made of bismuth telluride. The element tellurium is expected to be in short supply if TE cooling is widely implemented for auto air conditioning; some options available in this regard were studied and presented in this paper.

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

SciTech Connect

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.

A window on urban sustainability  

SciTech Connect

Sustainable urban development requires the integration of environmental interests in urban planning. Although various methods of environmental assessment have been developed, plan outcomes are often disappointing due to the complex nature of decision-making in urban planning, which takes place in multiple arenas within multiple policy networks involving diverse stakeholders. We argue that the concept of decision windows can structure this seemingly chaotic chain of interrelated decisions. First, explicitly considering the dynamics of the decision-making process, we further conceptualized decision windows as moments in an intricate web of substantively connected deliberative processes where issues are reframed within a decision-making arena, and interests may be linked within and across arenas. Adopting this perspective in two case studies, we then explored how decision windows arise, which factors determine their effectiveness and how their occurrence can be influenced so as to arrive at more sustainable solutions. We conclude that the integration of environmental interests in urban planning is highly dependent on the ability of the professionals involved to recognize and manipulate decision windows. Finally, we explore how decision windows may be opened. -- Highlights: Decision-making about sustainable urban development occurs in networks. The concept of decision windows was further elaborated. Decision windows help understand how environmental interests enter decision-making. Decision windows can, to some extent, be influenced.

Apparatus for preventing particle deposition from process streams on optical access windows  

DOE Patents (OSTI)

An electrostatic precipitator is disposed inside and around the periphery of the window of a viewing port communicating with a housing through which a particle-laden gas stream is being passed. The precipitator includes a pair of electrodes around the periphery of the window, spaced apart and connected to a unidirectional voltage source. Application of high voltage from the source to the electrodes causes air molecules in the gas stream to become ionized, attaching to solid particles and causing them to be deposited on a collector electrode. This prevents the particles from being deposited on the window and keeps the window clean for viewing and making optical measurements.

A signal processing system which accepts input from an x-ray detector-preamplifier and produces a signal of reduced dynamic range for subsequent analog-to-digital conversion is disclosed. The system conditions the input signal to reduce the number of bits required in the analog-to-digital converter by removing that part of the input signal which varies only slowly in time and retaining the amplitude of the pulses which carry information about the x-rays absorbed by the detector. The parameters controlling the signal conditioner`s operation can be readily supplied in digital form, allowing it to be integrated into a feedback loop as part of a larger digital x-ray spectroscopy system. 13 figs.

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. Key findings are summarized.

However krypton is more expensive than argon, currently used for most of multi-pane windows. The high price of krypton is due to the energy-intensive cryogenic process for its recovery from oxygen that is obtained from air. Ionic liquids may provide a cost-effective absorption process for separation of krypton from the oxygen stream of a liquid-air plant. The polarizability of krypton is higher than that of oxygen; therefore, krypton solubility may be

Rigid thin windows for vacuum applications  

DOE Patents (OSTI)

A thin window that stands off atmospheric pressure is fabricated using photolithographic and wet chemical etching techniques and comprises at least two layers: an etch stop layer and a protective barrier layer. The window structure also comprises a series of support ribs running the width of the window. The windows are typically made of boron-doped silicon and silicon nitride and are useful in instruments such as electron beam guns and x-ray detectors. In an electron beam gun, the window does not impede the electrons and has demonstrated outstanding gun performance and survivability during the gun tube manufacturing process.

An Experimental and Analytical Evaluation of Wall And Window Retrofit Configurations: Supporting the Residential Retrofit Best Practices Guide  

SciTech Connect

A Retrofit Best Practices Guide was developed to encourage homeowners to consider energy conservation issues whenever they modify their siding or windows. In support of this guide, an experimental program was implemented to measure the performance of a number of possible wall siding and window retrofit configurations. Both thermal and air-leakage measurements were made for a 2.4 x 2.4 m (8 x 8 ft) wall section with and without a 0.9 x 1.2 m (3 x 4 ft) window. The windows tested were previously well-characterized at a dedicated window test facility. A computer model was also used to provide information for the Best Practices Guide. The experimental data for walls and windows were used in conjunction with this model to estimate the total annual energy savings for several typical houses in a number of different locations.

Performance evaluation of CSI-based unified power quality conditioner using artificial neural network  

Science Journals Connector (OSTI)

In recent years unified power quality conditioner (UPQC) is being used as a universal active power conditioning device to mitigate both current as well as voltage harmonics at a distribution end of power system network. The performance of UPQC mainly depends upon how quickly and accurately compensation signals are derived. The artificial neural network (ANN) trained with conventional compensator data, can deliver compensation signals more accurately and quickly than conventional compensator at varied load condition. This paper presents performance verification of CSI-based UPQC using artificial neural network. The ANN-based compensation system eliminates voltage as well as current harmonics with good dynamic response. Extensive simulation results using Matlab/Simulink for RL load connected through an uncontrolled bridge rectifier validates the performance of ANN compensator.

Method and apparatus for analog signal conditioner for high speed, digital x-ray spectrometer  

DOE Patents (OSTI)

A signal processing system which accepts input from an x-ray detector-preamplifier and produces a signal of reduced dynamic range for subsequent analog-to-digital conversion. The system conditions the input signal to reduce the number of bits required in the analog-to-digital converter by removing that part of the input signal which varies only slowly in time and retaining the amplitude of the pulses which carry information about the x-rays absorbed by the detector. The parameters controlling the signal conditioner's operation can be readily supplied in digital form, allowing it to be integrated into a feedback loop as part of a larger digital x-ray spectroscopy system.

Considerations for Window Performance Considerations for Window Performance Advanced window technologies can have a major effect on comfort and on the annual energy performance of a house. However, there is a broader and possibly more significant impact of the recent revolution in window performance. Because the new glazing technologies provide highly effective insulating value and solar protection, there are important implications for how a house is designed. There is a long-established set of window design guidelines and assumptions intended to reduce heating and cooling energy use. These are based, in part, on the historical assumption that windows were the weak link in the building envelope. These assumptions frequently created limitations on design freedom or generated conflicts with other performance requirements,

Guidance on Window Durability Guidance on Window Durability There is no simple rating or absolute guarantee of the durability of a window. You may want to study the design and workmanship of the window and rely on recommendations from others who have used similar products. The advice of experienced architects and builders can be helpful. As with other products, warranties can be an indicator of the reliability of the window and its manufacturer. Durability may vary with location; for example, some materials are degraded by salt near the ocean. These aspects of window durability deserve special attention: frame and sashes; insulating glass seals; weatherstripping; and local requirements for structural integrity.

Room air conditioners typically extract heat from the room and vent it outdoors. These products are offered in a broad range of sizes and configurations. They are used in homes, apartments, and commercial settings. The standard implemented in 1990 will save approximately 0.7 quads of energy and result in approximately $8 billion in energy bill savings for products shipped from 1990-2019. The standard will avoid about 41.4 million metric tons of carbon dioxide emissions, equivalent to the annual greenhouse gas emissions of about 8.1 million automobiles.

Reduced Condensation Reduced Condensation Condensation High performance windows with new glazing technologies not only reduce energy costs but make homes more comfortable as well. High-performance windows create warmer interior glass surfaces, reducing frost and condensation. High-performance windows with warm edge technology and insulating frames have such a warm interior surface that condensation on any interior surfaces is significantly reduced under all conditions. Condensation occurs when the interior surface temperature of the glass drops below either the dewpoint or frost point. A window's frame and/or glazing system can contribute to the possibility of condensation if they are poor performers for a specific climate. High-performance windows create warmer interior glass surfaces, reducing condensation and frost.

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.

Measuring Performance: Visible Transmittance (VT) Measuring Performance: Visible Transmittance (VT) How to maximize daylight? Historically, only clear glass was used to maximize the amount of light entering through a window. Especially in cooling-dominated climate, this desirable daylight also came with undesirable solar heat gain. With the advancement of high-performance glazing systems, it is possible for low-E coatings to reject the solar heat gain while allowing the visible light to pass through the glass. The type of low-E coating that is appropriate for your specific house depends on location, orientation, window area, and shading strategies. The visible transmittance (VT) is an optical property that indicates the fraction of visible light transmitted through the window. This is separate from the Solar Heat Gain Coefficient (SHGC), since many modern windows

NREL Electrochromic Window Research Wins Award  

ScienceCinema (OSTI)

Winners of the CO-LABS Governor's Award for High-Impact Research in Energy Efficiency, Dr. Satyen Deb at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) discovered that a small electrical charge can change the opacity of tungsten oxide from clear to tinted. He, Dr. Dane Gillaspie, and their fellow scientists at NREL then applied this knowledge to develop and transfer the technologies required to construct an electrochromic window, which can switch between clear and heavily tinted states. Electrochromic windows allow natural light in while adding tint to reduce summer heat and glare, and going clear to allow sunlight through in the winter. Broad adaptation of these windows could reduce US total energy use by four percent and reduce building cooling loads by 20%, much of this during expensive peak hours. Windows based on these discoveries are now being installed worldwide.

Sound transmission loss of double?glazed window panesan empirical approach  

Science Journals Connector (OSTI)

There are only a few contributions to the theory of sound transmission loss (STL) of double?glazed window panes e.g. by M. Rehfeld et al. (1996). The situation is nearly the same with the empirical approach of reducing data from laboratory measurements to a simple formula as done by K. Goesele (1977). Goesele inferred a result in terms of the single?number rating according to ISO 717 based on many laboratory STL measurements as described in DIN 52210 and ISO 140. In particular measurements of air?filled double?glazed window panes had been used. Meanwhile the gas fillings changed because the thermal insulation of the window panes had to be increased. In the last five years a large number of STL measurements of double?glazed window panes with different dimensions (pane thicknesses gap between the panes) and gas fillings have been carried out at the Fraunhofer?Institut fuer Bauphysik. From these measurements some typical behaviors of STL versus frequency belonging to specific pane configurations could be derived. This should allow an approximate prediction of the STL for given physical dimensions of double?glazed window panes.

Study of solar-assisted thermoelectric technology for automobile air conditioning  

SciTech Connect

An analytical study was conducted to determine the feasibility of employing solar energy assisted thermoelectric (TE) cooling technology in automobile air conditioners. The study addressed two key issues -- power requirements and availability of thermoelectric materials. In this paper a mathematical model was developed to predict the performance of TE air conditioners and to analyze power consumption. Results show that the power required to deliver a cooling capacity of 4 kW (13,680 Btu/h) in a 38 C (100 F) environment will be 9.5 kW electric. Current TE modules suitable for air conditioning are made of bismuth telluride. The element tellurium is expected to be in short supply if TE cooling is widely implemented for auto air conditioning; some options available in this regard were studied and presented in this paper. The photovoltaic (PV) cells, assumed to cover the roof area of a compact car can only generate about 225 W. However, this is more than enough to power a fan to provide air ventilation to the car interior which significantly reduces the peak cooling load when the car is parked in bright sunlight.

Craig Drumheller, Christian Kohler, and Stefanie Minen Conference Name Thermal Performance of the Exterior Envelopes of Whole Buildings X International Conference Volume 277 Date Published 12/2007 Conference Location Clearwater Beach, FL Abstract A field evaluation comparing the performance of low emittance (low-e) storm windows with both standard clear storm windows and no storm windows was performed in a cold climate. Six homes with single pane windows were monitored over the period of one heating season. The homes were monitored with no storm windows and with new storm windows. The storm windows installed on four of the six homes included a hard coat, pyrolitic, low-e coating while the storm windows for the other two homes had traditional clear glass. Overall heating load reduction due to the storm windows was 13% with the clear glass and 21% with the low-e windows. Simple paybacks for the addition of the storm windows were 10 years for the clear glass and 4.5 years for the low-e storm windows.

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.

Jonsson, and Maria Konstantoglou Call Number LBNL-4416E Abstract Nowadays, virtual models are commonly used to evaluate the performance of conventional window systems. Complex fenestration systems can be difficult to simulate accurately not only because of their geometry but also because of their optical properties that scatter light in an unpredictable manner. Bi-directional Scattering Distribution Functions (BSDF) have recently been developed based on a mixture of measurements and modelling to characterize the optics of such systems. This paper describes the workflow needed to create then use these BSDF datasets in the Radiance lighting simulation software. Limited comparisons are made between visualizations produced using the standard ray-tracing method, the BSDF method, and that taken in a full-scale outdoor mockup.

Determining window solar heat gain coefficient  

SciTech Connect

The solar heat gain characteristics of fenestration systems impact daytime building energy performance, occupant comfort and utility load demands. A measure of the fraction of available solar energy entering a building interior per unit window area is defined as the solar heat gain coefficient (SHGC). Together with a window's thermal transmittance (U-value), the SHGC is used to compare fenestration products, and it allows for the calculation of energy rating number and annual energy performance. The need to measure and compared advances in window technology has led to the development of experimental and analytical methods for the determination of SHGC performance. Several test facilities currently or previously capable of performing SHGC measurements exist worldwide. Results experimentally determined using these facilities have provided design data for handbook tables, and have been instrumental in the development and validation of predictive analytical methods and computer simulation tools. However, these facilities have operated without a standard test procedure for SHGC performance. Consequently, recent efforts have been focused on developing consensus test procedures for the evaluation of window energy performance.

Improving the Energy Efficiency of Existing Windows Improving the Energy Efficiency of Existing Windows Improving the Energy Efficiency of Existing Windows October 15, 2008 - 10:56am Addthis Jen Carter What does this mean for me? There are several solutions to energy inefficient windows whether you're starting from scratch or simply making upgrades. But, soft! What light through yonder window breaks? It is the east, and Juliet is the sun. - William Shakespeare, Romeo and Juliet No one would dispute the undeniable beauty of soft, dappled light shining through a window in the early morning. Unless, of course, you happen to be one of the many Americans whose windows are letting in more than just light. Poorly fitted or sealed windows can be a major frustration during the winter months, letting in cold drafts that blur the lines between

Triple Low-E Glazing Triple Low-E Glazing Triple-Glazed, High-solar-gain Low-E Glass This figure illustrates the performance of a window with a very low heat loss rate (low U-factor). In this case there are three glazing layers and two low-E coatings, ½" argon gas or ¼" krypton gas fill between glazings, and low-conductance edge spacers. The middle glazing layer can be glass or suspended plastic film. Some windows use four glazing layers (two glass layers and two suspended plastic films). This product is suited for buildings located in very cold climates. Both Low-E coatings in this product have high solar heat and visible light transmittance, which is ideal for passive solar design. The use of three layers, however, results in lower solar heat gain relative to double glazing with high-solar-gain Low-E.

Vacuum Glazing; A Thermally Insulating Window Technology Vacuum Glazing; A Thermally Insulating Window Technology Speaker(s): Cenk Kocer Date: May 31, 2012 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Sunnie Lim The vacuum glazing consists of two panes of glass separated by a sub-millimetre vacuum gap. Under the action of atmospheric pressure the separation of the panes is maintained by an array of high strength spacers in the gap. The glass panes are hermetically sealed at the edge using a low melting point glass frit (solder glass). Since 1913 many have worked on a practical implementation of such a flat insulating glass structure, with success finally being reported in 1989 by Collins et al. at the University of Sydney. The purpose of this talk is to present a brief history of the vacuum glazing research at the University of Sydney, and outline in detail

Window Technologies: Glazing Types Window Technologies: Glazing Types Glazing Improvements There are three fundamental approaches to improving the energy performance of glazing products (two or more of these approaches may be combined). The first approach is to alter the glazing material itself by changing its chemical composition or physical characteristics. An example of this is tinted glazing. The second approach is to apply a coating to the glazing material surface. Reflective coatings and films were developed to reduce heat gain and glare, and more recently, low-emittance coatings have been developed to improve both heating and cooling season performance. The third approach is to assemble various layers of glazing and control the properties of the spaces between the layers. These strategies include the use of two or more panes or films,

Power Line Calculator for Windows[trademark  

SciTech Connect

The Power Line Calculator (PLC) for Windows [trademark], version 1.0, is a program that describes the electrical characteristics of a transmission or distribution system given user-defined input. This input may consist of a combination of operating currents and phases, symmetric components, power factor, and real or reactive power. The program also allows the user to designate whether currents are present on the system neutral or in the ground. The PLC assumes that any value entered by the user remains fixed (e.g., phase current, power factor), and for underdetermined systems, basic default assumptions are incorporated: the power factor is held at or near 1.0, the net phase current is kept at or near zero, and the phase conductor currents are kept balanced. The program operates through a graphical user interface provided by Microsoft[reg sign] Windows [trademark] (version 3.1 or higher required), and the output is available in both tabular and graphic formats.

Developing Low-Conductance Window Frames: Capabilities and Limitations of Developing Low-Conductance Window Frames: Capabilities and Limitations of Current Window Heat Transfer Design Tools Title Developing Low-Conductance Window Frames: Capabilities and Limitations of Current Window Heat Transfer Design Tools Publication Type Journal Article LBNL Report Number LBNL-1022E Year of Publication 2008 Authors Gustavsen, Arlid, Dariush K. Arasteh, Bjørn Petter Jelle, Dragan C. Curcija, and Christian Kohler Journal Journal of Building Physics Volume 32 Pagination 131-153 Call Number LBNL-1022E Abstract While window frames typically represent 20-30% of the overall window area, their impact on the total window heat transfer rates may be much larger. This effect is even greater in low-conductance (highly insulating) windows which incorporate very low conductance glazings. Developing low-conductance window frames requires accurate simulation tools for product research and development. Based on a literature review and an evaluation of current methods of modeling heat transfer through window frames, we conclude that current procedures specified in ISO standards are not sufficiently adequate for accurately evaluating heat transfer through the low-conductance frames.

The auditor checked some of the windows, which are double-paned, and showed me cracks between the window frame and the house that should be caulked. She recommended caulking both the inside and outside. That's easy enough for me to do -- at least the inside -- so I got some clear caulking and some gadgets to ensure a smooth finish from the home improvement store (I LOVE gadgets). I'm planning to start with the downstairs windows to perfect my technique, and at one window a week, hopefully I'll be finished
