Our Environment in Hot Water: Comparing Water Heaters, A Life Cycle Approach Comparing Tank and Tankless Water Heaters in California  

SciTech Connect

Residential water heating is a large source of energy use in California homes. This project took a life cycle approach to comparing tank and tankless water heaters in Northern and Southern California. Information about the life cycle phases was calculated using the European Union?s Methodology study for EcoDesign of Energy-using Products (MEEUP) and the National Renewable Energy Laboratory?s Life Cycle Inventory (NREL LCI) database. In a unit-to-unit comparison, it was found that tankless water heaters would lessen impacts of water heating by reducing annual energy use by 2800 MJ/year (16% compared to tank), and reducing global warming emissions by 175 kg CO2 eqv./year (18% reduction). Overall, the production and combustion of natural gas in the use phase had the largest impact. Total waste, VOCs, PAHs, particulate matter, and heavy-metals-to-air categories were also affected relatively strongly by manufacturing processes. It was estimated that tankless water heater users would have to use 10 more gallons of hot water a day (an increased usage of approximately 20%) to have the same impact as tank water heaters. The project results suggest that if a higher percentage of Californians used tankless water heaters, environmental impacts caused by water heating would be smaller.

Feasibility of Using Measurements of Internal Components ofTankless Water Heaters for Field Monitoring of Energy and Water Use  

SciTech Connect

The objective of this study was to determine if it was feasible to collect information regarding energy use and hot water delivery from tankless gas water heaters using the sensors and controls built into the water heaters. This could then be used to determine the water heater efficiency ? the ratio of energy out (hot water delivered) to energy in (energy in the gas) in actual residential installations. The goal was to be as unobtrusive as possible, and to avoid invalidating warranties or exposing researchers to liability issues. If feasible this approach would reduce the costs of instrumentation.This paper describes the limited field and laboratory investigations to determine if using the sensors and controls built into tankless water heaters is feasible for field monitoring.It was more complicated to use the existing gas flow, water and temperature sensors than was anticipated. To get the signals from the existing sensors and controls is difficult and may involve making changes that would invalidate manufacturer warrantees. The procedures and methods for using signals from the existing gas valves, water flow meters and temperature sensors will vary by model. To be able to monitor different models and brands would require detailed information about each model and brand.Based on these findings, we believe that for field monitoring projects it would be easier, quicker and safer to connect external meters to measure the same parameters rather than using the sensors and controls built into tankless water heaters.

AWSWAH - the heat pipe solar water heater  

SciTech Connect

An all weather heat pipe solar water heater (AWSWAH) comprising a collector of 4 m/sup 2/ (43 ft/sup 2/) and a low profile water tank of 160 liters (42 gal.) was developed. A single heat pipe consisting of 30 risers and two manifolds in the evaporator and a spiral condenser was incorporated into the AWSWAH. Condensate metering was done by synthetic fiber wicks. The AWSWAH was tested alongside two conventional solar water heaters of identical dimensions, an open loop system and a closed loop system. It was found that the AWSWAH was an average of 50% more effective than the open system in the temperature range 30-90 /sup 0/C (86-194 /sup 0/F). The closed loop system was the least efficient of the three systems.

Effect of Fuel Wobbe Number on Pollutant Emissions from Advanced Technology Residential Water Heaters: Results of Controlled Experiments  

SciTech Connect

The research summarized in this report is part of a larger effort to evaluate the potential air quality impacts of using liquefied natural gas in California. A difference of potential importance between many liquefied natural gas blends and the natural gas blends that have been distributed in California in recent years is the higher Wobbe number of liquefied natural gas. Wobbe number is a measure of the energy delivery rate for appliances that use orifice- or pressure-based fuel metering. The effect of Wobbe number on pollutant emissions from residential water heaters was evaluated in controlled experiments. Experiments were conducted on eight storage water heaters, including five with ultra low-NO{sub X} burners, and four on-demand (tankless) water heaters, all of which featured ultra low-NO{sub X} burners. Pollutant emissions were quantified as air-free concentrations in the appliance flue and fuel-based emission factors in units of nanogram of pollutant emitter per joule of fuel energy consumed. Emissions were measured for carbon monoxide (CO), nitrogen oxides (NO{sub X}), nitrogen oxide (NO), formaldehyde and acetaldehyde as the water heaters were operated through defined operating cycles using fuels with varying Wobbe number. The reference fuel was Northern California line gas with Wobbe number ranging from 1344 to 1365. Test fuels had Wobbe numbers of 1360, 1390 and 1420. The most prominent finding was an increase in NO{sub X} emissions with increasing Wobbe number: all five of the ultra low-NO{sub X} storage water heaters and two of the four ultra low-NO{sub X} on-demand water heaters had statistically discernible (p<0.10) increases in NO{sub X} with fuel Wobbe number. The largest percentage increases occurred for the ultra low-NO{sub X} water heaters. There was a discernible change in CO emissions with Wobbe number for all four of the on-demand devices tested. The on-demand water heater with the highest CO emissions also had the largest CO increase with increasing fuel Wobbe number.

Utilization of Heat Pump Water Heaters for Load Management  

SciTech Connect

The Energy Conservation Standards for Residential Water Heaters require residential electric storage water heaters with volumes larger than 55 gallons to have an energy factor greater than 2.0 after April 2015. While this standard will significantly increase the energy efficiency of water heaters, large electric storage water heaters that do not use heat pump technologies may no longer be available. Since utilities utilize conventional large-volume electric storage water heaters for thermal storage in demand response programs, there is a concern that the amended standard will significantly limit demand response capacity. To this end, Oak Ridge National Laboratory partnered with the Tennessee Valley Authority to investigate the load management capability of heat pump water heaters that meet or exceed the forthcoming water heater standard. Energy consumption reduction during peak periods was successfully demonstrated, while still meeting other performance criteria. However, to minimize energy consumption, it is important to design load management strategies that consider the home s hourly hot water demand so that the homeowner has sufficient hot water.

The Impact of Blowing Agents on Residential Water Heater Performance  

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

The Impact of Blowing Agents on Residential Water Heater Performance The Impact of Blowing Agents on Residential Water Heater Performance Title The Impact of Blowing Agents on Residential Water Heater Performance Publication Type Report LBNL Report Number LBNL-47352 Year of Publication 2001 Authors Lekov, Alexander B., James D. Lutz, Camilla Dunham Whitehead, and James E. McMahon Document Number LBNL-47352 Date Published January 12 Abstract The National Appliance Energy Conservation Act of 1987 (NAECA) requires the U.S. Department of Energy (DOE) to consider amendments to the energy conservation standards to increase energy efficiency in residential water heaters. A driving force affecting efficiency is the ozone-depletion regulation regarding blowing agents for insulation in all water heater fuel types. This paper presents results of cost and efficiency impacts of three potential blowing agents. Residential water heaters are typically insulated with polyurethane foam in the space between the tank and the jacket. Currently, water heater manufacturers use HCFC-141b, an ozone-depleting substance, as a blowing agent. After 2003, as a result of the Montreal Protocol (1993), manufacturers must use blowing agents that do not deplete the ozone layer. The analysis presented in this paper considers three replacement candidates, HFC-245fa, HFC-134a, and cyclopentane by comparing their efficiency and cost effectiveness when applied to water heater insulation. This analysis used computer simulation models and other analytical methods to investigate the efficiency improvements due to different design options, when alternative blowing agents are applied. The calculations were based on the DOE test procedure for residential water heaters. The analysis used average manufacturer, retailer, and installer costs to calculate the total consumer costs. Consumer operating expenses were calculated based on modeled energy consumption under test procedure conditions and U.S. average energy prices. With this information, a cost-efficiency relationship was developed to show the average manufacturer and consumer cost to achieve increased efficiency.

Determining Benefits and Costs of Improved Water Heater Efficiencies Determining Benefits and Costs of Improved Water Heater Efficiencies Title Determining Benefits and Costs of Improved Water Heater Efficiencies Publication Type Report LBNL Report Number LBNL-45618 Year of Publication 2000 Authors Lekov, Alexander B., James D. Lutz, Xiaomin Liu, Camilla Dunham Whitehead, and James E. McMahon Document Number LBNL-45618 Date Published May 4 Abstract Economic impacts on individual consumers from possible revisions to U.S. residential water heater energy-efficiency standards are examined using a life-cycle cost (LCC) analysis. LCC is the consumer's cost of purchasing and installing a water heater 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 are significant. At the efficiency level examined in this paper, 35% of households with electric water heaters experience LCC savings, with an average savings of $106, while 4% show LCC losses, with an average loss of $40 compared to a pre-standard LCC average of $2,565. The remainder of the population (61%) are largely unaffected.

Experimental study of integrated collector storage solar water heaters  

Science Journals Connector (OSTI)

Three Integrated Collector Storage Solar Water Heaters (ICSSWH) have been designed, constructed and experimentally studied in comparison to a Flat Plate Thermosiphonic Unit (FPTU). Each of the ICS experimental models consists of one cylindrical tank horizontally mounted in a stationary symmetrical Compound Parabolic Concentrating (CPC) reflector trough. The main objective is the design and construction of low cost solar water heaters with improved thermal performance and lower possible depths. The experimental models can be mounted on horizontal as well as on inclined roofs by adopting the lowest possible depth. The results show that these solar devices perform more than effectively all year long. This could contribute significantly on the development of ICS type solar water heaters.

Development of a Market Optimized Condensing Gas Water Heater  

SciTech Connect

This program covered the development of a market optimized condensing gas water heater for residential applications. The intent of the program was to develop a condensing design that minimized the large initial cost premium associated with traditional condensing water heater designs. Equally important was that the considered approach utilizes design and construction methods that deliver the desired efficiency without compromising product reliability. Standard condensing water heater approaches in the marketplace utilize high cost materials such as stainless steel tanks and heat exchangers as well as expensive burner systems to achieve the higher efficiencies. The key in this program was to develop a water heater design that uses low-cost, available components and technologies to achieve higher efficiency at a modest cost premium. By doing this, the design can reduce the payback to a more reasonable length, increasing the appeal of the product to the marketplace. Condensing water heaters have been in existence for years, but have not been able to significantly penetrate the market. The issue has typically been cost. The high purchase price associated with existing condensing water heaters, sometimes as much as $2000, has been a very difficult hurdle to overcome in the marketplace. The design developed under this program has the potential to reduce the purchase price of this condensing design by as much as $1000 as compared to traditional condensing units. The condensing water heater design developed over the course of this program led to an approach that delivered the following performance attributes: 90%+ thermal efficiency; 76,000 Btu/hr input rate in a 50 gallon tank; First hour rating greater than 180 gph; Rapid recovery time; and Overall operating condition well matched to combination heat and hot water applications. Over the final three years of the program, TIAX worked very closely with A.O. Smith Water Products Company as our commercial partner to optimize the design for manufacturing. This work included the initiation of a large field testing program (over 125 units) and an in-depth reliability program intended to minimize the risks associated with a new product introduction. At the time of this report, A.O. Smith plans to introduce this product to the marketplace in the early 2006 time period.

Laboratory Performance Evaluation of Residential Integrated Heat Pump Water Heaters  

SciTech Connect

This paper explores the laboratory performance of five integrated Heat Pump Water Heaters (HPWHs) across a wide range of operating conditions representative of US climate regions. HPWHs are expected to provide significant energy savings in certain climate zones when compared to typical electric resistance water heaters. Results show that this technology is a viable option in most climates, but differences in control schemes and design features impact the performance of the units tested. Tests were conducted to map heat pump performance across the operating range and to determine the logic used to control the heat pump and the backup electric heaters. Other tests performed include two unique draw profile tests, reduced air flow performance tests and the standard DOE rating tests. The results from all these tests are presented here for all five units tested. The results of these tests will be used to improve the EnergyPlus heat pump water heater for use in BEopt(tm) whole-house building simulations.

Electric Water Heater Modeling and Control Strategies for Demand Response  

SciTech Connect

Abstract Demand response (DR) has a great potential to provide balancing services at normal operating conditions and emergency support when a power system is subject to disturbances. Effective control strategies can significantly relieve the balancing burden of conventional generators and reduce investment on generation and transmission expansion. This paper is aimed at modeling electric water heaters (EWH) in households and tests their response to control strategies to implement DR. The open-loop response of EWH to a centralized signal is studied by adjusting temperature settings to provide regulation services; and two types of decentralized controllers are tested to provide frequency support following generator trips. EWH models are included in a simulation platform in DIgSILENT to perform electromechanical simulation, which contains 147 households in a distribution feeder. Simulation results show the dependence of EWH response on water heater usage . These results provide insight suggestions on the need of control strategies to achieve better performance for demand response implementation.

An Evaluation of the Water Heater Load Potential for Providing Regulation Service  

SciTech Connect

This paper investigates the possibility of providing aggregated regulation services with small loads, such as water heaters or air conditioners. A direct-load control algorithm is presented to aggregate the water heater load for the purpose of regulation. A dual-element electric water heater model is developed, which accounts for both thermal dynamics and users water consumptions. A realistic regulation signal was used to evaluate the number of water heaters needed and the operational characteristics of a water heater when providing 2-MW regulation service. Modeling results suggest that approximately 33,333 water heaters are needed to provide a 2-MW regulation service 24 hours a day. However, if water heaters only provide regulation from 6:00 to 24:00, approximately 20,000 will be needed. Because the control algorithm has considered the thermal setting of the water heater, the customer comfort is obstructed little. Therefore, the aggregated regulation service provided by water heater loads can become a major source of revenue for load-service entities when the smart grid enables the direct load control.

Economics of residential gas furnaces and water heaters in United States new construction market  

SciTech Connect

New single-family home construction represents a significant and important market for the introduction of energy-efficient gas-fired space heating and water-heating equipment. In the new construction market, the choice of furnace and water-heater type is primarily driven by first cost considerations and the availability of power vent and condensing water heaters. Few analysis have been performed to assess the economic impacts of the different combinations of space and water-heating equipment. Thus, equipment is often installed without taking into consideration the potential economic and energy savings of installing space and water-heating equipment combinations. In this study, we use a life-cycle cost analysis that accounts for uncertainty and variability of the analysis inputs to assess the economic benefits of gas furnace and water-heater design combinations. This study accounts not only for the equipment cost but also for the cost of installing, maintaining, repairing, and operating the equipment over its lifetime. Overall, this study, which is focused on US single-family new construction households that install gas furnaces and storage water heaters, finds that installing a condensing or power-vent water heater together with condensing furnace is the most cost-effective option for the majority of these houses. Furthermore, the findings suggest that the new construction residential market could be a target market for the large-scale introduction of a combination of condensing or power-vent water heaters with condensing furnaces.

Design, modeling, and performance of four breadbox passive solar water heaters  

SciTech Connect

As part of the Southwest Border Regional Commission demonstration program on Solar Upgrading of Low-Income Housing, three different types of passive breadbox solar water heaters were designed. Using these designs, a total of six solar water heaters have been installed on public housing units in Las Cruces; these systems act as preheaters to the existing conventional gas-fired water heaters. Under a separate contract from the National Center for Appropriate Technology, four of these installations have been instrumented with two Btu meters each to measure the thermal output of both the solar preheater and conventional backup system. This has enabled measurement of the actual solar fraction of the four instrumented solar systems. The design and construction of the water heaters is described, and the actual performance of the systems is compared with the predicted performance.

An International Survey of Electric Storage Tank Water Heater Efficiency and Standards  

SciTech Connect

Water heating is a main consumer of energy in households, especially in temperate and cold climates. In South Africa, where hot water is typically provided by electric resistance storage tank water heaters (geysers), water heating energy consumption exceeds cooking, refrigeration, and lighting to be the most consumptive single electric appliance in the home. A recent analysis for the Department of Trade and Industry (DTI) performed by the authors estimated that standing losses from electric geysers contributed over 1,000 kWh to the annual electricity bill for South African households that used them. In order to reduce this burden, the South African government is currently pursuing a programme of Energy Efficiency Standards and Labelling (EES&L) for electric appliances, including geysers. In addition, Eskom has a history of promoting heat pump water heaters (HPWH) through incentive programs, which can further reduce energy consumption. This paper provides a survey of international electric storage water heater test procedures and efficiency metrics which can serve as a reference for comparison with proposed geyser standards and ratings in South Africa. Additionally it provides a sample of efficiency technologies employed to improve the efficiency of electric storage water heaters, and outlines programs to promote adoption of improved efficiency. Finally, it surveys current programs used to promote HPWH and considers the potential for this technology to address peak demand more effectively than reduction of standby losses alone

Field Performance of Heat Pump Water Heaters in the Northeast, Massachusetts and Rhode Island (Fact Sheet)  

SciTech Connect

Heat pump water heaters (HPWHs) are finally entering the mainstream residential water heater market. Potential catalysts are increased consumer demand for higher energy efficiency electric water heating and a new Federal water heating standard that effectively mandates use of HPWHs for electric storage water heaters with nominal capacities greater than 55 gallons. When compared to electric resistance water heating, the energy and cost savings potential of HPWHs is tremendous. Converting all electric resistance water heaters to HPWHs could save American consumers 7.8 billion dollars annually ($182 per household) in water heating operating costs and cut annual residential source energy consumption for water heating by 0.70 quads. Steven Winter Associates, Inc. embarked on one of the first in situ studies of these newly released HPWH products through a partnership with two sponsoring electric utility companies, National Grid and NSTAR, and one sponsoring energy efficiency service program administrator, Cape Light Compact. Recent laboratory studies have measured performance of HPWHs under various operating conditions, but publicly available field studies have not been as available. This evaluation attempts to provide publicly available field data on new HPWHs by monitoring the performance of three recently released products (General Electric GeoSpring, A.O. Smith Voltex, and Stiebel Eltron Accelera 300). Fourteen HPWHs were installed in Massachusetts and Rhode Island and monitored for over a year. Of the 14 units, ten were General Electric models (50 gallon units), two were Stiebel Eltron models (80 gallon units), and two were A.O. Smith models (one 60-gallon and one 80-gallon unit).

Heat Pump Water Heater Technology Assessment Based on Laboratory Research and Energy Simulation Models: Preprint  

SciTech Connect

This paper explores the laboratory performance of five integrated Heat Pump Water Heaters (HPWHs) across a wide range of operating conditions representative of US climate regions. Laboratory results demonstrate the efficiency of this technology under most of the conditions tested and show that differences in control schemes and design features impact the performance of the individual units. These results were used to understand current model limitations, and then to bracket the energy savings potential for HPWH technology in various US climate regions. Simulation results show that HPWHs are expected to provide significant energy savings in many climate zones when compared to other types of water heaters (up to 64%, including impact on HVAC systems).

Analysis of water heater standby energy consumption from ELCAP homes  

Science Journals Connector (OSTI)

The Bonneville Power Administration (Bonneville) routinely prepares forecasts of future energy demands in the Pacific Northwest region of the United States. Bonneville also implements conservation programs to reduce load demands. Results from the End-Use Load and Consumer Assessment Program (ELCAP), undertaken by the Pacific Northwest Laboratory for Bonneville, indicated that single-family homes with electric space-heating equipment consume more than 4700 kWh/yr to heat water for domestic uses. This energy use amounts to about 23% of the total electricity consumed. Additionally, the peak consumption for water heating coincides with regional system peak demands. Detailed analyses of the water heating end-use data acquired for residential buildings in ELCAP reveal that the average standby load for existing homes is 1200 kWh/yr, while homes built as part of the Residential Standards Demonstration Program averaged 1100 kWh/yr. These figures are consistent with the current figure of 1300 kWh/yr that is being used in the regional energy forecast. We also determined that standby loads for some of the participants were behaviorally driven. The data indicated the occurrence of vacancy setbacks in which the participant appears to lower the thermostat to save energy while the house is vacant. Anecdotal evidence from interviews revealed that this does occur. Reasons for setting back the thermostat ranged from not thinking about using the breaker, to fear that the tank would freeze in cold weather. These types of activities also appear to create the occurrence of dueling thermostats where the upper and lower thermostats, after the vacancy period, are not returned to the same temperature. This leads to additional energy use in an attempt to maintain a uniform temperature in the tank.

Control Strategy for Domestic Water Heaters during Peak Periods and its Impact on the Demand for Electricity  

Science Journals Connector (OSTI)

Because they store hot water, water heaters are easily-shifted loads that can be controlled to reduce peak demands. However, load shifting may have some detrimental consequences on the domestic hot water supply temperature if the heating element is deactivated for a long period of time. Furthermore, a new peak may be caused if a significant number of heaters are reactivated at the same time. This study presents a control strategy for water heaters that minimizes the pick-up demand when the heating elements are reactivated at the end of a load shifting period and that ensures, in all cases, the client's hot water supply. The study is based on a simulation model of a water heater that was experimentally validated and takes into account the diversity of the population's hot water withdrawal profile. More specifically, the data of 8,167 real water withdrawal profiles of several clients were input into the simulation model in order to evaluate the performance of water heaters under different operating conditions.

Retrofit Integrated Space & Water Heating: Field Assessment, Minneapolis, Minnesota (Fact Sheet)  

SciTech Connect

This project analyzed combined condensing water heaters or boilers and hydronic air coils to provide high efficiency domestic hot water and forced air space heating. Called 'Combi' systems, they provided similar space and water heating performance less expensively than installing two condensing appliances. The system's installed costs were cheaper than installing a condensing furnace and either a condensing tankless or condensing storage water heater. However, combi costs must mature and be reduced before they are competitive with a condensing furnace and power vented water heater (EF of 0.60). Better insulation and tighter envelopes are reducing space heating loads for new and existing homes. For many homes, decreased space heating loads make it possible for both space and domestic water heating loads to be provided with a single heating plant. These systems can also eliminate safety issues associated with natural draft appliances through the use of one common sealed combustion vent.

Impact of Pilot Light Modeling on the Predicted Annual Performance of Residential Gas Water Heaters: Preprint  

SciTech Connect

Modeling residential water heaters with dynamic simulation models can provide accurate estimates of their annual energy consumption, if the units? characteristics and use conditions are known. Most gas storage water heaters (GSWHs) include a standing pilot light. It is generally assumed that the pilot light energy will help make up standby losses and have no impact on the predicted annual energy consumption. However, that is not always the case. The gas input rate and conversion efficiency of a pilot light for a GSWH were determined from laboratory data. The data were used in simulations of a typical GSWH with and without a pilot light, for two cases: 1) the GSWH is used alone; and 2) the GSWH is the second tank in a solar water heating (SWH) system. The sensitivity of wasted pilot light energy to annual hot water use, climate, and installation location was examined. The GSWH used alone in unconditioned space in a hot climate had a slight increase in energy consumption. The GSWH with a pilot light used as a backup to an SWH used up to 80% more auxiliary energy than one without in hot, sunny locations, from increased tank losses.

However, significant barriers must be overcome before this technology will reach widespread adoption in the Pacific Northwest region and nationwide. One significant barrier noted by the Northwest Energy Efficiency Alliance (NEEA) is the possible interaction with the homes space conditioning system for units installed in conditioned spaces. Such complex interactions may decrease the magnitude of whole-house savings available from HPWH installed in the conditioned space in cold climates and could lead to comfort concerns (Larson et al. 2011; Kresta 2012). Modeling studies indicate that the installation location of HPWHs can significantly impact their performance and the resultant whole-house energy savings (Larson et al. 2012; Maguire et al. 2013). However, field data are not currently available to validate these results. This field evaluation of two GE GeoSpring HPWHs in the PNNL Lab Homes is designed to measure the performance and impact on the Lab Home HVAC system of a GE GeoSpring HPWH configured with exhaust ducting compared to an unducted GeoSpring HPWH during heating and cooling season periods; and measure the performance and impact on the Lab Home HVAC system of the GeoSpring HPWH with both supply and exhaust air ducting as compared to an unducted GeoSpring HPWH during heating and cooling season periods. Important metrics evaluated in these experiments include water heater energy use, HVAC energy use, whole house energy use, interior temperatures (as a proxy for thermal comfort), and cost impacts. This technical report presents results from the PNNL Lab Homes experiment.

Modeling of Electric Water Heaters for Demand Response: A Baseline PDE Model  

SciTech Connect

Demand response (DR)control can effectively relieve balancing and frequency regulation burdens on conventional generators, facilitate integrating more renewable energy, and reduce generation and transmission investments needed to meet peak demands. Electric water heaters (EWHs) have a great potential in implementing DR control strategies because: (a) the EWH power consumption has a high correlation with daily load patterns; (b) they constitute a significant percentage of domestic electrical load; (c) the heating element is a resistor, without reactive power consumption; and (d) they can be used as energy storage devices when needed. Accurately modeling the dynamic behavior of EWHs is essential for designing DR controls. Various water heater models, simplified to different extents, were published in the literature; however, few of them were validated against field measurements, which may result in inaccuracy when implementing DR controls. In this paper, a partial differential equation physics-based model, developed to capture detailed temperature profiles at different tank locations, is validated against field test data for more than 10 days. The developed model shows very good performance in capturing water thermal dynamics for benchmark testing purposes

Development of Environmentally Benign Heat Pump Water Heaters for the US Market  

SciTech Connect

Improving energy efficiency in water heating applications is important to the nation's energy strategies. Water heating in residential and commercial buildings accounts for about 10% of U.S. buildings energy consumption. Heat pump water heating (HPWH) technology is a significant breakthrough in energy efficiency, as an alternative to electric resistance water heating. Heat pump technology has shown acceptable payback period with proper incentives and successful market penetration is emerging. However, current HPWH require the use of refrigerants with high Global Warming Potential (GWP). Furthermore, current system designs depend greatly on the backup resistance heaters when the ambient temperature is below freezing or when hot water demand increases. Finally, the performance of current HPWH technology degrades greatly as the water set point temperature exceeds 330 K. This paper presents the potential for carbon dioxide, CO2, as a natural, environmentally benign alternative refrigerant for HPWH technology. In this paper, we first describe the system design, implications and opportunities of operating a transcritical cycle. Next, a prototype CO2 HPWH design featuring flexible component evaluation capability is described. The experimental setup and results are then illustrated followed by a brief discussion on the measured system performance. The paper ends with conclusions and recommendations for the development of CO2 heat pump water heating technology suitable for the U.S. market.

Thermal performance analysis of a direct-expansion solar-assisted heat pump water heater  

Science Journals Connector (OSTI)

A direct-expansion solar-assisted heat pump water heater (DX-SAHPWH) is described, which can supply hot water for domestic use during the whole year. The system mainly employs a bare flat-plate collector/evaporator with a surface area of 4.2m2, an electrical rotary-type hermetic compressor, a hot water tank with the volume of 150L and a thermostatic expansion valve. R-22 is used as working fluid in the system. A simulation model based on lumped and distributed parameter approach is developed to predict the thermal performance of the system. Given the structure parameters, meteorological parameters, time step and final water temperature, the numerical model can output operational parameters, such as heat capacity, system COP and collector efficiency. Comparisons between the simulation results and the experimental measurements show that the model is able to give satisfactory predictions. The effect of various parameters, including solar radiation, ambient temperature, wind speed and compressor speed, has been analyzed on the thermal performance of the system.

Experimental investigation of the night heat losses of hot water storage tanks in thermosyphon solar water heaters  

Science Journals Connector (OSTI)

The effects of night heat losses on the performance of thermosyphon solar water heaters have been experimentally examined. Three typical thermosyphon solar water heating systems with different storage tank sizes were tested by utilising the method suggested by ISO 9459-2:95. The results were analysed to quantify the night heat losses and to investigate the effect that these may have on the system daily performance. Analysis of the results showed that a linear behavior of the heat losses with the night mean ambient temperature exists. The correlation coefficients of the linearity for the three systems under consideration range from 0.93 to 0.97 with the losses reaching almost 8000 kJ at a mean ambient air temperature of 10 C. This value represents a significant percentage of the daily collected energy making the night losses one of the most important sources of energy loss in thermosyphonic systems.

Short term performance comparisons between a solar thermosyphon water heater and two numerical models  

SciTech Connect

An experimental study of a solar thermosyphon domestic water heater was conducted in the indoor solar simulator facility at Colorado State University (Bickford, 1994). The system consisted of a closed-loop collector circuit filled with propylene glycol and water solution and a horizontal storage tank with an annular tank-in-tank heat exchanger. Short-term irradiated tests with and without timed draws were performed to assess overall performance and monitor collector flow rate, storage tank stratification, and heat exchanger temperature distribution. The measured performance was compared with the ``standard`` thermosyphon model in TRNSYS 13.1 (transient system simulation program). A revised TRNSYS model was developed by Graham Morrison at the University of New South Wales, Australia. The revised model specifically addressed the horizontal tank, closed-loop configuration. The standard TRNSYS version predicted solar gain within 17% of the measured values and differed dramatically from experimental collector temperatures, closed-loop flow rate, and tank stratification. This is not surprising since this model does not include the tank and tank heat exchanger. The revised TRNSYS model agreed more closely with experimental results. It predicted closed-loop flow at 8% lower than observed flow and collector temperature rise that was higher than the observed flow by approximately the same amount, resulting in extremely accurate prediction of collector output energy. Losses from the storage tank and piping were significantly underpredicted in both models, however.

Development of a cogenerating thermophotovoltaic powered combination hot water heater/hydronic boiler  

Science Journals Connector (OSTI)

A cogenerating thermophotovoltaic (TPV) device for hot water hydronic space heating and electric power generation was developed designed fabricated and tested under a Department of Energy contracted program. The device utilizes a cylindrical ytterbia superemissive ceramic fiber burner (SCFB) and is designed for a nominal capacity of 80 kBtu/hr. The burner is fired with premixed natural gas and air. Narrow band emission from the SCFB is converted to electricity by single crystal silicon (Si) photovoltaic (PV) arrays arranged concentrically around the burner. A three-way mixing valve is used to direct heated water to either the portable water storage tank radiant baseboard heaters or both. As part of this program QGI developed a microprocessor-based control system to address the safety issues as well as photovoltaic power management. Flame sensing is accomplished via the photovoltaics a technology borrowed from QGIs Quantum Control safety shut-off system. Device testing demonstrated a nominal photovoltaic power output of 200 W. Power consumed during steady state operation was 33 W with power drawn from the combustion air blower hydronic system pump three-way switching valve and the control system resulting in a net power surplus of 142 W. Power drawn during the ignition sequence was 55 W and a battery recharge time of 1 minute 30 seconds was recorded. System efficiency was measured and found to be more than 83%. Pollutant emissions at determined operating conditions were below the South Coast Air Quality Management Districts (California) limit of 40 ng/J for NOx and carbon monoxide emissions were measured at less than 50 dppm.

Auto-Calibration and Control Strategy Determination for a Variable-Speed Heat Pump Water Heater Using Optimization  

SciTech Connect

This paper introduces applications of the GenOpt optimizer coupled with a vapor compression system model for auto-calibration and control strategy determination towards the development of a variable-speed ground-source heat pump water heating unit. The GenOpt optimizer can be linked with any simulation program using input and output text files. It effectively facilitates optimization runs. Using our GenOpt wrapper program, we can flexibly define objectives for optimizations, targets, and constraints. Those functionalities enable running extensive optimization cases for model calibration, configuration design and control strategy determination. In addition, we describe a methodology to improve prediction accuracy using functional calibration curves. Using the calibrated model, we investigated control strategies of the ground-source heat pump water heater, considering multiple control objectives, covering the entire operation range.

Solar-assisted auto-cascade heat pump cycle with zeotropic mixture R32/R290 for small water heaters  

Science Journals Connector (OSTI)

Abstract In this study, a novel solar-assisted auto-cascade heat pump cycle (SAHPC) operating with the zeotropic mixture of R32/R290 for small water heaters is proposed. In the SAHPC system, a cascade heat exchanger (CHEX) associated with a phase separator is used to achieve auto cascade cycle and enhance the overall system performance. The performances of the SAHPC are evaluated by using the developed mathematical model, and then compared with the conventional air-sourced heat pump cycle (CAHPC). Simulation results show the SAHPC has 4.239.85% and 4.379.68% improvements in COP and volumetric heating capacity compared with those of the CAHPC, respectively, under the same operating conditions. However, the improvement of performance of this novel cycle largely depends on the absorbing heat ratio and the zeotropic composition. It is expected that this new cycle will be beneficial to developing dual-source coupled heat pump applications.

Performance of a Heat Pump Water Heater in the Hot-Humid Climate, Windermere, Florida (Fact Sheet), Building America Case Study: Technology Solutions for New and Existing Homes, Building Technologies Office (BTO)  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Performance of a Performance of a Heat Pump Water Heater in the Hot-Humid Climate Windermere, Florida Over recent years, heat pump water heaters (HPWHs) have become more read- ily available and more widely adopted in the marketplace. A key feature of an HPWH unit is that it is a hybrid system. When conditions are favorable, the unit will operate in heat pump mode (using a vapor compression system that extracts heat from the surrounding air) to efficiently provide domestic hot water (DHW). Homeowners need not adjust their behavior to conform to the heat pump's capabilities. If a heat pump cannot meet a higher water draw demand, the heater will switch to electric resistance to provide a higher heating rate. This flexibility

Building America Case Study: Evaluation of Residential Integrated Space/Water Heat Systems, Illinois and New York (Fact Sheet)  

SciTech Connect

This multi-unit field demonstration of combined space and water heating (combi) systems was conducted to help document combi system installation and performance issues that needed to be addressed through research. The objective of the project was to put commercialized forced-air tankless combi units into the field through local contractors that were trained by manufacturers and GTI staff under the auspices of utility-implemented Emerging Technology Programs. With support from PARR, NYSERDA and other partners, the project documented system performance and installations in Chicago and New York. Combi systems were found to save nearly 200 therms in cold climates at efficiencies between about 80% and 94%. Combi systems using third-party air handler units specially designed for condensing combi system operation performed better than the packaged integrated combi systems available for the project. Moreover, combi systems tended to perform poorly when the tankless water heaters operating at high turn-down ratios. Field tests for this study exposed installation deficiencies due to contractor unfamiliarity with the products and the complexity of field engineering and system tweaking to achieve high efficiencies. Widespread contractor education must be a key component to market expansion of combi systems. Installed costs for combi systems need to come down about 5% to 10% to satisfy total resource calculations for utility-administered energy efficiency programs. Greater sales volumes and contractor familiarity can drive costs down. More research is needed to determine how well heating systems such as traditional furnace/water heater, combis, and heat pumps compare in similar as-installed scenarios, but under controlled conditions.

The minimum gas temperature at the inlet of regulators in natural gas pressure reduction stations (CGS) for energy saving in water bath heaters  

Science Journals Connector (OSTI)

Abstract In this study a computational procedure for the computation of JouleThomson coefficient of natural gas has been developed using fundamental thermodynamic equations and AGA-8 equation of state, and then the minimum possible temperature of the natural gas entering to the pressure regulator of city gate stations (CGS) is calculated. As a case study, a CGS located in Bistoon (of Iran's CGSs) with nominal capacity of 20,000 SCMH has been considered. A comparison has been made between the calculated results and corresponding collected data from the station within 10 months. Results of this study help to determine the minimum temperature values of entering gas with different pressures to the regulator in order to avoid hydrate formation of the outlet gas, and can be used to design appropriate temperature control systems for water bath heaters and in turn save consumed energy for gas heating. The results show that heating the gas up to calculated minimum temperatures can save energy consumption of heaters by 43%. Also, it is indicated that by applying a control system, based on the result of this study, in the CGS the payback period would be less than a year.

How They Work Heat pumps use electricity to capture heat and move it from one place to another. They don't generate heat. As the pool pump circulates the swimming pool's water, the water drawn from the pool passes through a filter and the heat pump heater. The heat pump heater has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating

Development of a gas backup heater for solar domestic hot-water systems. Final report, April 1978-April 1980  

SciTech Connect

A comprehensive program was undertaken to develop a unique gas fired backup for solar domestic hot water systems. Detailed computer design tools were written. A series of heat transfer experiments were performed to characterize the performance of individual components. A full scale engineering prototype, including the solar preheat tank and solar heat exchanger, was designed, fabricated and subjected to limited testing. Firing efficiency for the backup system was found to be 81.4% at a firing rate of 50,000 Btu/h. Long term standby losses should be negligible.

Phase change material storage heater  

DOE Patents (OSTI)

A storage heater for storing heat and for heating a fluid, such as water, has an enclosure defining a chamber therein. The chamber has a lower portion and an upper portion with a heating element being disposed within the enclosure. A tube through which the fluid flows has an inlet and an outlet, both being disposed outside of the enclosure, and has a portion interconnecting the inlet and the outlet that passes through the enclosure. A densely packed bed of phase change material pellets is disposed within the enclosure and is surrounded by a viscous liquid, such as propylene glycol. The viscous liquid is in thermal communication with the heating element, the phase change material pellets, and the tube and transfers heat from the heating element to the pellets and from the pellets to the tube. The viscous fluid has a viscosity so that the frictional pressure drop of the fluid in contact with the phase change material pellets substantially reduces vertical thermal convection in the fluid. As the fluid flows through the tube heat is transferred from the viscous liquid to the fluid flowing through the tube, thereby heating the fluid.

NEXT GENERATION COMMERCIAL HEAT PUMPWATER HEATER USING CARBON DIOXIDE USING DIFFERENT IMPROVEMENT APPROACHES  

SciTech Connect

Although heat pump water heaters are today widely accepted in Japan, where energy costs are high and government incentives for their use exist, acceptance of such a product in the U.S. has been slow. This trend is slowly changing with the introduction of heat pump water heaters into the residential market, but remains in the commercial sector. Barriers to heat pump water heater acceptance in the commercial market have historically been performance, reliability and first/operating costs. The use of carbon dioxide (R744) as the refrigerant in such a system can improve performance for relatively small increase in initial cost and make this technology more appealing. What makes R744 an excellent candidate for use in heat pump water heaters is not only the wide range of ambient temperatures within which it can operate, but also the excellent ability to match water to refrigerant temperatures on the high side, resulting in very high exit water temperatures of up to 82?ºC, as required by sanitary codes in the U.S. (Food Code, 2005), in a single pass, temperatures that are much more difficult to reach with other refrigerants. This can be especially attractive in applications where this water is used for the purpose of sanitation. While reliability has also been of concern historically, dramatic improvements have been made over the last several years through research done in the automotive industry and commercialization of R744 technology in residential water heating mainly in Japan. This paper presents the performance results from the development of an R744 commercial heat pump water heater of approximately 35 kW and a comparison to a baseline R134a unit of the same capacity and footprint. In addition, recommendations are made for further improvements of the R744 system which could result in possible energy savings of up to 20 %.

Eleana near-surface heater experiment final report  

SciTech Connect

This report summarizes the results of a near-surface heater experiment operated at a depth of 23 m in argillite within the Eleana Formation on the Nevada Test Site (NTS). The test geometrically simulated emplacement of a single canister of High-Level Waste (HLW) and was operated at a power level of 2.5 kW for 21 days, followed by 3.8 kW to 250 days, when the power was turned off. Below 85 to 100{sup 0}C, there was good agreement between modeled and measured thermal results in the rock and in the emplacement hole, except for transient transport of water in the heater hole. Above 100{sup 0}C, modeled and measured thermal results increasingly diverged, indicating that the in-situ rock-mass thermal conductivity decreased as a result of dehydration more than expected on the basis of matrix properties. Correlation of thermomechanical modeling and field results suggests that this decrease was caused by strong coupling of thermal and mechanical behavior of the argillite at elevated temperatures. No hole-wall decrepitation was observed in the experiment; this fact and the codrrelation of modeled and measured results at lower temperatures indicate that there is no a priori reason to eliminate argillaceous rocks from further consideration as a host rock for nuclear wastes.

Advanced refinery process heater. Annual report, October 1983-September 1984  

SciTech Connect

Activity during the first year of this project has focused on the conceptual design of the prototype heater and on the development of a custom-designed Pyrocore ceramic fiber burner for the heater. Three different concepts for the prototype heater have been produced, one of them modeled after a vertical cylindrical design and the other two resembling box-type heaters. All three concepts take advantage of the Pyrocore burner's flameless characteristic to make the heater more compact. Concerning the development of the burners, two different geometries were considered. Subscale prototypes of each type of burner were fabricated and tested. The more successful burners used actively-cooled edges to maintain the integrity of the gas-tight seals. Work on this project in the second year will include the design and fabrication of the 10 MMBtu/hr prototype heater, using the most feasible heater and burner designs developed during the first year.

Lid heater for glass melter  

DOE Patents (OSTI)

A glass melter having a lid electrode for heating the glass melt radiantly. The electrode comprises a series of INCONEL 690 tubes running above the melt across the melter interior and through the melter walls and having nickel cores inside the tubes beginning where the tubes leave the melter interior and nickel connectors to connect the tubes electrically in series. An applied voltage causes the tubes to generate heat of electrical resistance for melting frit injected onto the melt. The cores limit heat generated as the current passes through the walls of the melter. Nickel bus connection to the electrical power supply minimizes heat transfer away from the melter that would occur if standard copper or water-cooled copper connections were used between the supply and the INCONEL 690 heating tubes.

Enhanced heat transfer tubes for film absorbers of absorption chiller/heater  

SciTech Connect

Absorption chiller/heaters using non-CFC refrigerants are attracting attention as environmentally friendly energy systems. As the refrigerant/absorbent pair, the water/lithium bromide aqueous solution pair is preferably used for most absorption chiller/heaters in Japan. Absorption chiller/heaters, mainly used as water chillers and air-conditioners, are commercially available at least for unit cooling capacities above 60 kW. In absorption chiller/heaters, the absorber must be made compact, because the absorber has the largest heat transfer area of the four primary heat exchangers in the system: the evaporator, absorber, regenerator and condenser. Although a great amount of information is available on the evaporator and condenser, the same type of information concerning the absorber is lacking. This paper introduces two kinds of double fluted tubes called Arm tubs and Floral tubes for film absorbers. Arm tubes are manufactured using a two-pass drawbench process, while Floral tubes are made using a single pass drawbench process. The experiments using a lithium bromide aqueous solution with the addition of 250 ppm n-octyl alcohol as the surfactant showed that Arm tubes and Floral tubes had about 40% higher heat transfer performance than plain tubes. Therefore, Floral tubes are expected to realize a high performance at low cost. Furthermore, the optimization of the number of grooves on the outside of the tubes is also described here.

Advanced refinery process heater. Final report, (October 1983-September 1988)  

SciTech Connect

A prototype refinery process heater was designed, built and successfully tested, demonstrating the improvements available to heater design through the use of Zone-Controlled Pyrocore radiant gas burners. The 10 MMBtu/hr rated heater released 17 ppm NOx (corrected to 3% oxygen) under full load operation, the lowest NOx emissions technically and commercially achieved in this type of equipment without the use of post-combustion flue-gas processing. Operating with 400F combustion air preheat and a 500F process fluid outlet temperature, the heater achieved overall thermal efficiencies of 92.8% on a LHV basis due in part to the significantly improved performance of the radiant heat exchange section. The radiant burners used in the heater have been proven in performance and reliability, and have also been shown to be applicable to both new heater designs and retrofits into existing heaters. The improved radiant performance of the heater and the use of 'flameless' radiant burners eliminates tube burn-out failures in both the radiant and convective tube coils, further improving the reliability of equipment based on this design. Three separate U.S. Patents have been issued covering the heater design and the use of Zone-Controlled Pyrocore burners in this application.

Slurry fired heater cold-flow modelling  

SciTech Connect

This report summarizes the experimental and theoretical work leading to the scale-up of the SRC-I Demonstration Plant slurry fired heater. The scale-up involved a theoretical model using empirical relations in the derivation, and employed variables such as flow conditions, liquid viscosity, and slug frequency. Such variables have been shown to affect the heat transfer characteristics ofthe system. The model assumes that, if all other variables remain constant, the heat transfer coefficient can be scaled up proportional to D/sup -2/3/ (D = inside diameter of the fired heater tube). All flow conditions, liquid viscosities, and pipe inclinations relevant to the demonstration plant have indicated a slug flow regime in the slurry fired heater. The annular and stratified flow regimes should be avoided to minimize the potential for excessive pipe erosion and to decrease temperature gradients along the pipe cross section leading to coking and thermal stresses, respectively. Cold-flow studies in 3- and 6.75-in.-inside-diameter (ID) pipes were conducted to determine the effect of scale-up on flow regime, slug frequency, and slug dimensions. The developed model assumes that conduction heat transfer occurs through the liquid film surrounding the gas slug and laminar convective heat transfer to the liquid slug. A weighted average of these two heat transfer mechanisms gives a value for the average pipe heat transfer coefficient. The cold-flow work showed a decrease in the observed slug frequency between the 3- and 6.75-ID pipes. Data on the ratio of gas to liquid slug length in the 6.75-in. pipe are not yet complete, but are expected to yield generally lower values than those obtained in the 3-in. pipe; this will probably affect the scale-up to demonstration plant conditions. 5 references, 15 figures, 7 tables.

Performance characteristics of solar air heater with surface mounted obstacles  

Science Journals Connector (OSTI)

Abstract The performance of conventional solar air heaters (SAHs) can be improved by providing obstacles on the heated wall (i.e. on the absorber plate). Experiments have been performed to collect heat transfer and flow-friction data from an air heater duct with delta-shaped obstacles mounted on the absorber surface and having an aspect ratio 6:1 resembling the conditions close to the solar air heaters. This study encompassed for the range of Reynolds number (Re) from 2100 to 30,000, relative obstacle height (e/H) from 0.25 to 0.75, relative obstacle longitudinal pitch (Pl/e) from 3/2 to 11/2, relative obstacle transverse pitch (Pt/b) from 1 to 7/3 and the angle of incidence (?) varied from 30 to 90. The thermo-hydraulic performance characteristics of SAH have been compared with the previous published works and the optimum range of the geometries have been explored for the better performance of such air-heaters compared to the other designs of solar air heaters.

Feedback regulated induction heater for a flowing fluid  

DOE Patents (OSTI)

A regulated induction heater for heating a stream of flowing fluid to a predetermined desired temperature. The heater includes a radiofrequency induction coil which surrounds a glass tube through which the fluid flows. A heating element consisting of a bundle of approximately 200 stainless steel capillary tubes located within the glass tube couples the output of the induction coil to the fluid. The temperature of the fluid downstream from the heating element is sensed with a platinum resistance thermometer, the output of which is applied to an adjustable porportional and integral feedback control circuit which regulates the power applied to the induction coil. The heater regulates the fluid temperature to within 0.005/sup 0/C at a flow rate of 50 cm/sup 3//sec with a response time of less than 0.1 second, and can accommodate changes in heat load up to 1500 watts.

Three-phase heaters with common overburden sections for heating subsurface formations  

DOE Patents (OSTI)

A heating system for a subsurface formation is described. The heating system includes three substantially u-shaped heaters with first end portions of the heaters being electrically coupled to a single, three-phase wye transformer and second end portions of the heaters being electrically coupled to each other and/or to ground. The three heaters may enter the formation through a first common wellbore and exit the formation through a second common wellbore so that the magnetic fields of the three heaters at least partially cancel out in the common wellbores.

Feasibility of accompanying uncontrolled linear heater with solar system innatural gas pressure drop stations  

Science Journals Connector (OSTI)

Natural gas (NG) must be preheated before pressure reduction takes places at City Gate Stations (CGS). Indirect Water Bath Gas Heaters are employed in the CGS for preheating. The heaters consume a considerable amount of NG for preheating. As low temperature is required, a solar system has been proposed to provide part of heat demand. The system consists of a collector array and a storage tank. The tank stores solar heat during the day and releases it during the night. To show the capabilities of the proposed system, the Akand CGS has been chosen as a case study. The results show that as the number of collector increases, the fuel cost decreases but the capital cost increases. An optimum number of collectors and the storage tank capacity have been found based on economic analysis. The fuel saving occurs throughout the year with the maximum at June. The economic feasibility study of the proposed system has been carried out using two methods. These methods are Simple Payback Ratio (SPR) and (Net Present Value) NPV. The first one unveils that the payback ratio is only 6.9 years. The NPV method shows that the system will give net benefit after 11 years.

Impacts of Water Quality on Residential Water Heating Equipment  

SciTech Connect

Water heating is a ubiquitous energy use in all residential housing, accounting for 17.7% of residential energy use (EIA 2012). Today, there are many efficient water heating options available for every fuel type, from electric and gas to more unconventional fuel types like propane, solar, and fuel oil. Which water heating option is the best choice for a given household will depend on a number of factors, including average daily hot water use (total gallons per day), hot water draw patterns (close together or spread out), the hot water distribution system (compact or distributed), installation constraints (such as space, electrical service, or venting accommodations) and fuel-type availability and cost. While in general more efficient water heaters are more expensive than conventional water heating technologies, the savings in energy use and, thus, utility bills can recoup the additional upfront investment and make an efficient water heater a good investment over time in most situations, although the specific payback period for a given installation will vary widely. However, the expected lifetime of a water heater in a given installation can dramatically influence the cost effectiveness and savings potential of a water heater and should be considered, along with water use characteristics, fuel availability and cost, and specific home characteristics when selecting the optimum water heating equipment for a particular installation. This report provides recommendations for selecting and maintaining water heating equipment based on local water quality characteristics.

Alternatives for reducing hot-water bills  

SciTech Connect

A two stage approach to reducing residential water heating bills is described. In Stage I, simple conservation measures were included to reduce the daily hot water energy consumption and the energy losses from the water tank. Once these savings are achieved, Stage II considers more costly options for further reducing the water heating bill. Four alternatives are considered in Stage II: gas water heaters; solar water heaters (two types); heat pump water heaters; and heat recovery from a heat pump or air conditioner. To account for variations within the MASEC region, information on water heating in Rapid City, Minneapolis, Chicago, Detroit, and Kansas City is presented in detail. Information on geography, major population centers, fuel prices, climate, and state solar incentives is covered. (MCW)

Full-scale cold-flow modelling of the SRC-I slurry fired heater at Creare, Inc. mixing and 1/sup 0/ downslope studies  

SciTech Connect

One of the major pieces of equipment in the SRC-I Demonstration Plant is the slurry fired heater. Because of the absence of any plant data at comparable combinations of operating severity, a cold-flow modelling experimental program was initiated at Creare, Inc. The first phase of the test program confirmed the fired heater design and established reliable boundaries of flow rates for proper operation of the fired heater. An experimental setup was designed and built at Creare to duplicate the piping arrangement and flow conditions of the fired heater. The pipe dimensions, flow rates, and fluid properties were selected to minimize areas of scale-up and extrapolation. This follow-up test program was developed to resolve concerns raised from the observations made in the first phase. Tests were conducted to establish the extent of mixing between the liquid carpet and the fast-moving liquid slugs above it. The other segment of the test program was designed to develop the flow regime and pressure drop data in the 1/sup 0/ downslope configuration. The results demonstrated a significant amount of mixing between the liquid carpet and the liquid slugs for water and the 400-cP fluid at the design flow conditions. The extent of mixing improved with increasing liquid and gas velocities and decreasing liquid viscosities. Adequate mixing was observed at liquid flow rates as low as 50% of the design flow conditions. Slug flow was observed at design conditions in the 1/sup 0/ downslope configuration. Although adequate mixing is expected in heater pipes, different techniques should be investigated to improve the extent of mixing, especially near the transition boundary. 4 references, 5 figures, 8 tables.

Enhancement of Heat Transfer in an Artificially Roughened Solar Air Heater  

E-Print Network (OSTI)

Abstract: solar air heater is one of the basic equipment through which solar energy is converted into thermal energy. Solar air heaters, because of their simple in design, are cheap and most widely used collection devices of solar energy. The thermal efficiency of a solar air heater is significantly low because of the low value of the convective heat transfer coefficient between the absorber plate and the air, leading to high absorber plate temperature and high heat losses to the surroundings. This paper presents the study of heat transfer in a solar air heater by using Computational Fluid Dynamics (CFD). The effect of Reynolds number on Nusselt number is investigated. A commercial finite volume package ANSYS FLUENT 12.1 is used to analyze and visualize the nature of the flow across the duct of a solar air heater.

Evaluation of a Stirling engine heater bypass with the NASA Lewis nodal-analysis performance code  

SciTech Connect

In support of the US Department of Energy's Stirling Engine Highway Vehicle Systems program, the NASA Lewis Research Center investigated whether bypassing the P-40 Stirling engine heater during regenerative cooling would improve the engine thermal efficiency. The investigation was accomplished by using the Lewis nodal-analysis Stirling engine computer model. Bypassing the P-40 Stirling engine heater at full power resulted in a rise in the indicated thermal efficiency from 40.6 to 41.0 percent. For the idealized (some losses not included) heater bypass that was analyzed, this benefit is not considered significant.

Subsidiary Authors Energy Analysis Department Document Number LBNL-5187E Pagination 21 Date Published January Publisher Lawrence Berkeley National Laboratory City Berkeley ISBN Number LBNL-5187E Abstract The American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Standards Project Committee (SPC) 118.2, Method of Testing for Rating Residential Water Heaters, is seeking to improve the test procedure used for measuring the energy efficiency of residential gas and electric water heaters. ASHRAE is seeking to develop an improved test procedure in part to support the U.S. Department of Energy's (DOE's) desire to update and amend the water heater test procedure underlying the minimum energy efficiency standards for water heaters. DOE's test procedures are often based on or reference ASHRAE standards.DOE's most recent minimum energy performance standards (MEPS) for residential water heaters were promulgated in 2010.[1] The associated test procedures are stipulated in the Code of Federal Regulations (CFR).[2] Although DOE currently is conducting a rulemaking to review and possibly amend the test procedures for residential water heaters, that rulemaking pertains to accounting for energy consumed during standby and off modes. In its notice of proposed rulemaking published in the Federal Register on August 30, 2010, DOE tentatively concluded that the test procedure for water heaters already fully accounts for and incorporates the energy consumed during standby and off modes [3].

Combustion air preheating for refinery heaters using plate-type heat exchangers  

SciTech Connect

Combustion air preheating by recovering heat from combustion gases is a cost effective method of increasing the overall thermal efficiency of the refining and petrochemical processes. This paper presents the advantages of the plate-type air preheaters made of smooth plates without extended surfaces. These exchangers provide a relatively high heat transfer coefficient at a relatively low pressure drop, resulting in a flexible and compact design. The air preheater design can easily be integrated into the heater design. Top mounting with natural draft becomes possible for many applications, eliminating the need for I.D. fan and expensive ductwork. The economical extent of heat recovery function of the fuel fired is presented based on practical experience. The use of porcelain enameled (glass coated) plates and of stainless steel materials allows the operation of the air preheater below the acidic and water dew point. Finally the paper presents the experience of the Canadian refineries and petrochemical plants with plate-type heat exchangers used for combustion air preheating.

Performance of unglazed solar ventilation air pre-heaters for broiler barns  

Science Journals Connector (OSTI)

Solar radiation is an interesting heat source for applications requiring a limited amount of energy, such as pre-heating cold fresh air used in venting livestock barns. The objective of this study was to evaluate the energy recovery efficiency of a solar air pre-heater consisting of an unglazed perforated black corrugated siding where the incoming fresh ventilation air picks up heat from its face and back. Installed on the southeast wall of two broiler barns located 40km east of Montreal, Canada, the performance of solar air pre-heaters was monitored over 2years. Sensors inside the barns monitored the temperature of the ambient air, that pre-heated by the solar collector and that exhausted by one of the three operating fans. An on-site weather station measured ambient air temperature, wind direction and velocity and radiation energy absorbed on a vertical plane parallel to the unglazed solar air pre-heaters. The measured vertical solar radiation value was used to evaluate the heat recovery efficiency of the unglazed solar air pre-heaters. Using data from the Varennes Environment Canada weather station located 30km northwest, the solar sensors were found to measure the absorbed solar radiation with a maximum error of 7%, including differences in exterior air moisture. Unglazed, the efficiency of the solar air pre-heaters reached 65% for wind velocities under 2m/s, but dropped below 25% for wind velocities exceeding 7m/s. Nevertheless, the unglazed solar air pre-heaters were able to reduce the heating load especially in March of both years. Over a period starting in November and ending in March, the solar air heaters recovered an energy value equivalent to an annual return on investment of 4.7%.

Development status of coal-fired gas heaters for Brayton-cycle cogeneration systems  

SciTech Connect

Under contract from the Department of Energy, Rocketdyne is developing the technology of coal-fired gas heaters for utilization in Brayton-cycle cogeneration systems. The program encompasses both atmospheric fluidized bed and pulverized coal combustion systems; and it is directed toward the development of gas heater systems capable of delivering high pressure air or helium at 1550 F, when employing metallic heat exchangers, and 1750 F, when employing ceramic heat exchangers. This paper reports on the development status of the program, with discussions of the completed ''screening'' corrosion/erosion tests of candidate heat exchanger materials, a description and summary of the operating experience with the 6- by 6-foot AFB test facility and a projection of the potential for relatively near term commercialization of such heater systems.

Refractory oxides for high?temperature coal?fired MHD air heaters  

Science Journals Connector (OSTI)

In a coal?burning MHD (Magnetohydrodynamic) power plant the use of a regenerative air heater is one option for producing the required high plasma temperatures. However thermal mechanical and chemical stresses which the MHD environment places on materials are enormous and candidate materials must be carefully tested. We report on the results of such testing for a variety of materials studied in heater test facilities at both FluiDyne Engineering Corporation and at Montana State University. We describe the experimental program and test facilities for MHD heater development the rationale for the choice of materials and their performance (success or failure) under various envirnoments (slagging and nonslagging). Future materials needs are discussed in light of the observed effects.

Experimental investigations on decay heat removal in advanced nuclear reactors using single heater rod test facility: Air alone in the annular gap  

SciTech Connect

During a loss of coolant accident in nuclear reactors, radiation heat transfer accounts for a significant amount of the total heat transfer in the fuel bundle. In case of heavy water moderator nuclear reactors, the decay heat of a fuel bundle enclosed in the pressure tube and outer concentric calandria tube can be transferred to the moderator. Radiation heat transfer plays a significant role in removal of decay heat from the fuel rods to the moderator, which is available outside the calandria tube. A single heater rod test facility is designed and fabricated as a part of preliminary investigations. The objective is to anticipate the capability of moderator to remove decay heat, from the reactor core, generated after shut down. The present paper focuses mainly on the role of moderator in removal of decay heat, for situation with air alone in the annular gap of pressure tube and calandria tube. It is seen that the naturally aspirated air is capable of removing the heat generated in the system compared to the standstill air or stagnant water situations. It is also seen that the flowing moderator is capable of removing a greater fraction of heat generated by the heater rod compared to a stagnant pool of boiling moderator. (author)

Water preheater system  

SciTech Connect

A heat transfer liquid collects heat in a solar collector and transfers the heat to water in a preheater heat exchanger. Use of a negative-pressure collector by means of an ejector and pressure relief valve allows inexpensive and readily available materials to be used in the collector. Preferably, the preheat heat exchanger is a converted gas hot water heater in which the heat transfer liquid is sprayed onto a portion of the storage tank and is collected in a reservoir. The negative-pressure solar collector can also be used to heat swimming pool water.

Eliminating air heater plugging and corrosion caused by SCR/SNCR systems for NOx control on coal-fired boilers  

SciTech Connect

In a typical coal-fired power plant the rotary regenerative air heater is responsible for 5-10% of the boiler's total efficiency. The three biggest threats to air heater performance deterioration are corrosion of the heat exchange surfaces, plugging, and air heater leakage through the seals. The article concentrates on the vastly increased level of corrosion and plugging issues associated with installing selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) systems for controlling nitrogen oxide emissions. Some injected ammonia in the SCR process reacts with SO{sub 2} to form ammonium sulphate and bisulphate (ABS) which is deposited on the air heater element surfaces. This can be overcome by applying coatings, using corrosion-resistant steels, reconfiguring the air heaters to a two layer design, improving air heater blowers, improving technologies for removing ammonia 'slip' before it enters the air heater, and using new catalysts that reduce the oxidation of SO{sub 2} to SO{sub 3}. 4 figs.

Radiation Tolerant Programmable Power Supply for the LHC Beam Screen Heaters  

E-Print Network (OSTI)

For the next LHC run, it is required to install 200W of heating capacity per LHC beam screen heater to regenerate the beam screen by desorption of gas trapped on its walls. In the LHC, there are 272 beam screen heaters and the associated electronics limit presently the heating capacity to 25W. Those electronics are, for the most part, installed inside the LHC tunnel and exposed to its radiation environment. This paper describes the development of a new programmable power supply card that will be integrated into the existing LHC radiation tolerant electronic infrastructure used by the cryogenic system. Radiation tests were undertaken to qualify a power switch capable of coping with the 230Vrms grid voltage and an analog signal multiplexer; these components are required respectively for satisfying the higher power requirements and for reducing the overall cost by using a single analog to digital converter to sample all the signals.

Advanced Oxyfuel Boilers and Process Heaters for Cost Effective CO2 Capture and Sequestration  

SciTech Connect

The purpose of the advanced boilers and process heaters program is to assess the feasibility of integrating Oxygen Transport Membranes (OTM) into combustion processes for cost effective CO{sub 2} capture and sequestration. Introducing CO{sub 2} capture into traditional combustion processes can be expensive, and the pursuit of alternative methods, like the advanced boiler/process heater system, may yield a simple and cost effective solution. In order to assess the integration of an advanced boiler/process heater process, this program addressed the following tasks: Task 1--Conceptual Design; Task 2--Laboratory Scale Evaluation; Task 3--OTM Development; Task 4--Economic Evaluation and Commercialization Planning; and Task 5--Program Management. This Final report documents and summarizes all of the work performed for the DOE award DE-FC26-01NT41147 during the period from January 2002-March 2007. This report outlines accomplishments for the following tasks: conceptual design and economic analysis, oxygen transport membrane (OTM) development, laboratory scale evaluations, and program management.

Development and Field Trial of Dimpled-Tube Technology for Chemical Industry Process Heaters  

SciTech Connect

Most approaches to increasing heat transfer rates in the convection sections of gas-fired process heaters involve the incorporation of fins, baffles, turbulizers, etc. to increase either the heat transfer surface area or turbulence or both. Although these approaches are effective in increasing the heat transfer rates, this increase is invariably accompanied by an associated increase in convection section pressure drop as well as, for heaters firing dirty fuel mixtures, increased fouling of the tubes both of which are highly undesirable. GTI has identified an approach that will increase heat transfer rates without a significant increase in pressure drop or fouling rate. Compared to other types of heat transfer enhancement approaches, the proposed dimpled tube approach achieves very high heat transfer rates at the lowest pressure drops. Incorporating this approach into convection sections of chemical industry fired process heaters may increase energy efficiency by 3-5%. The energy efficiency increase will allow reducing firing rates to provide the required heating duty while reducing the emissions of CO2 and NOx.

Cornell University Hot Water Report  

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

Hot Water System Hot Water System The production and delivery of hot water in the CUSD home is technologically advanced, economical, and simple. Hot water is produced primarily by the evacuated solar thermal tube collectors on the roof of the house. The solar thermal tube array was sized to take care of the majority of our heating and hot water needs throughout the course of the year in the Washington, DC climate. The solar thermal tube array also provides heating to the radiant floor. The hot water and radiant floor systems are tied independently to the solar thermal tube array, preventing the radiant floor from robbing the water heater of much needed thermal energy. In case the solar thermal tubes are not able to provide hot water to our system, the hot water tank contains an electric heating

Advanced Process Heater for the Steel, Aluminum and Chemical Industries of the Future  

SciTech Connect

The Roadmap for Process Heating Technology (March 16, 2001), identified the following priority R&D needs: Improved performance of high temperature materials; improved methods for stabilizing low emission flames; heating technologies that simultaneously reduce emissions, increase efficiency, and increase heat transfer. Radiant tubes are used in almost every industry of the future. Examples include Aluminum re-heat furnaces; Steel strip annealing furnaces, Petroleum cracking/ refining furnaces, Metal Casting/Heat Treating in atmosphere and fluidized bed furnaces, Glass lair annealing furnaces, Forest Products infrared paper driers, Chemical heat exchangers and immersion heaters, and the indirect grain driers in the Agriculture Industry. Several common needs among the industries are evident: (1) Energy Reductions, (2) Productivity Improvements, (3) Zero Emissions, and (4) Increased Component Life. The Category I award entitled Proof of Concept of an Advanced Process Heater (APH) for Steel, Aluminum, and Petroleum Industries of the Future met the technical feasibility goals of: (1) doubling the heat transfer rates (2) improving thermal efficiencies by 20%, (3) improving temperature uniformity by 100oF (38 oC) and (4) simultaneously reducing NOx and CO2 emissions. The APH addresses EEREs primary mission of increasing efficiency/reducing fuel usage in energy intensive industries. The primary goal of this project was to design, manufacture and test a commercial APH prototype by integrating three components: (1) Helical Heat Exchanger, (2) Shared Wall Radiant U-tube, and (3) Helical Flame Stabilization Element. To accomplish the above, a near net shape powder ceramic Si-SiC low-cost forming process was used to manufacture the components. The project defined the methods for making an Advanced Process Heater that produced an efficiency between 70% to 80% with temperature uniformities of less than 5oF/ft (9oC/m). Three spin-off products resulted from this project: (1) a low-cost, high-temperature heat exchanger, (2) a new radiant heat transfer system, and (3) a hybrid or integral advanced process heater that incorporates a high surface area ceramic heat exchanger and burner combined with either a metallic or ceramic radiant tube and heat transfer elements.

Research and Design of a Sample Heater for Beam Line 6-2c Transmission X-ray Microscope  

SciTech Connect

There exists a need for environmental control of samples to be imaged by the Transmission X-Ray Microscope (TXM) at the SSRLs Beam Line 6-2c. In order to observe heat-driven chemical or morphological changes that normally occur in situ, microscopes require an additional component that effectively heats a given sample without heating any of the microscope elements. The confinement of the heat and other concerns about the heaters integrity limit which type of heater is appropriate for the TXM. The bulk of this research project entails researching different heating methods used previously in microscopes, but also in other industrial applications, with the goal of determining the best-fitting method, and finally in designing a preliminary sample heater.

Analysis of thermal properties of basalt from heater Test No. 2 experiment  

SciTech Connect

Rockwell Hanford Operations is conducting a series of full-scale in situ tests at the Near Surface Test Facility (NSTF) near Richland, Washington as an integral part of the Basalt Waste isolation project. An objective of the Phase I tests, which include Main Heater Test No. 2, is to provide data for determination the material properties necessary for predicting the response of a repository system at depth. During the first 90 days Heater Test No. 2 represents the near-field response of a high-level waste canister which generates 1 kW of heat energy. The analysis of the thermal response of basalt from data collected during this initial heating period is described in this report. Values of thermal conductivity and heat capacity for basalt are determined using three methods referred to as type curve matching, Jacob's straight line method, and the Gauss-Newton parameter optimization method. Results indicate that the type curve and the Gauss-Newton methods give values which correspond relatively closely to those measured in the laboratory.

Low-Cost Solar Water Heating Research and Development Roadmap  

SciTech Connect

The market environment for solar water heating technology has changed substantially with the successful introduction of heat pump water heaters (HPWHs). The addition of this energy-efficient technology to the market increases direct competition with solar water heaters (SWHs) for available energy savings. It is therefore essential to understand which segment of the market is best suited for HPWHs and focus the development of innovative, low-cost SWHs in the market segment where the largest opportunities exist. To evaluate cost and performance tradeoffs between high performance hot water heating systems, annual energy simulations were run using the program, TRNSYS, and analysis was performed to compare the energy savings associated with HPWH and SWH technologies to conventional methods of water heating.
