Evaluating home heating options in Krakow  

SciTech Connect (OSTI)

The city of Krakow, Poland, has poor air quality due, in part, to widespread use of coal for heating. Engineering analyses have been conducted to determine the technical feasibility and capital costs for a number of options for reducing pollution from home heating sources. Capital costs range from $90 per kilowatt (kW) to connect local boiler-houses to the district heating system to $227/kW to upgrade the electrical system and convert coal stoves to electric heat. Air quality analyses have estimated the reduction in pollutant emissions as well as in pollutant concentrations that would result from implementing the options under consideration. Significant reductions can be obtained at a lower cost by using briquettes instead of coal in home stoves than by converting the stoves to electricity or gas. Finally, incentives analyses are examining the cost-effectiveness of the various alternatives and identifying possible incentives that the city could provide to encourage adoption of less-polluting technologies and practices.

Use of active solar heating and domestic hot water (DHW) systems in single family homes: technical findings and lessons learned from the HUD solar demonstration program  

SciTech Connect (OSTI)

This report describes the technical experiences with active solar space and domestic water heating systems installed in single family homes. It is intended to assist members of the home building and solar industries to provide their customers with satisfactory products and installations and to avoid some of the problems caused by improper equipment, system design, and installation. Two chapters focus on liquid and air systems. Problems are discussed by subsystem: collectors, transport, storage, distribution, and control. Industry responsibility, including cooperation during the construction phase and responsiveness during the occupancy phase, are considered. The conclusion notes that system efficiency, which now runs in the 10 to 30 - percent range, can be greatly improved if the solar and home building industries make greater efforts to properly insulate pipes, ducts, and storage; assure system operation at the proper time; and minimize leaks through valves or dampers. Additional suggestions are given. Graphs, photographs, footnotes, a glossary, and selected bibliographies are provided.

Geothermal home heating facilities, Green Valley Estates, Fernley, Nevada  

SciTech Connect (OSTI)

A housing development to be located at Fernley, Nevada, about thirty miles east of Reno, is in an area of known geothermal water. The practicality of heating these homes with this water, as an alternative to heating with natural gas, has been investigated. A preliminary engineering design of a geothermal system was developed. This design permitted capital and operating cost to be estimated and a financial evaluation to be made. Two cases were investigated. The Base Case provides facilities for heating a tract of 371 houses. The Alternate Case adds another tract of 371 for a total of 742 houses. Geothermal water is to be provided by two wells and the used water reinjected into a third well. The Base Case has a rate of return on capital investment of 13.0 percent before taxes. The Alternate Case has a rate of return of 16.5 percent before taxes. The Alternate Case has a more favorable return due primarily to the assumption that each well has the capacity to produce 800 gpm of geothermal water. This is enough to provide for the additional 371 houses in the Alternate Case without an additional well. (MHR)

Organic combustion fingerprints of three common home heating fuels  

SciTech Connect (OSTI)

The paper discusses the chemical structures of three common home heating fuels: wood, coal, and No. 2 fuel oil. GC and GC/MS data are then presented which demonstrate how the thermal destruction of each fuel results in the production of a characteristic group of organic 'fingerprint' compounds. For wood, where the chief structural element is lignin polymer, they are methoxy benzenes, methoxy phenols, and alkyl bezenes. For coal, where the polymer contains more fused-ring structures, the chief products are fused-ring aromatics with structures of three or more rings, benzothiophenes, and to a lesser extent methyl-substituted phenols. For oil, the chief byproducts are unburned droplets of the oil. The paper concludes with a brief discussion of how these fingerprints can be used as apportionment guides in complex airsheds.

Air-To-Water Heat Pumps with Radiant Delivery in Low Load Homes: Tucson, Arizona and Chico, California (Fact Sheet)  

SciTech Connect (OSTI)

Space conditioning represents nearly 50% of average residential household energy consumption, highlighting the need to identify alternative cost-effective, energy-efficient cooling and heating strategies. As homes are better built, there is an increasing need for strategies that are particularly well suited for high performance, low load homes. ARBI researchers worked with two test homes in hot-dry climates to evaluate the in-situ performance of air-to-water heat pump (AWHP) systems, an energy efficient space conditioning solution designed to cost-effectively provide comfort in homes with efficient, safe, and durable operation. Two monitoring projects of test houses in hot-dry climates were initiated in 2010 to test this system. Both systems were fully instrumented and have been monitored over one year to capture complete performance data over the cooling and heating seasons. Results are used to quantify energy savings, cost-effectiveness, and system performance using different operating modes and strategies. A calibrated TRNSYS model was developed and used to evaluate performance in various climate regions. This strategy is most effective in tight, insulated homes with high levels of thermal mass (i.e. exposed slab floors).

System Effects of High Efficiency Filters in Homes  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

System Effects of High Efficiency Filters in Homes System Effects of High Efficiency Filters in Homes Title System Effects of High Efficiency Filters in Homes Publication Type Conference Paper LBNL Report Number LBNL-6144E Year of Publication 2013 Authors Walker, Iain S., Darryl J. Dickerhoff, David Faulkner, and William J. N. Turner Conference Name ASHRAE Annual Conference Date Published 03/2013 Abstract Occupant concern about indoor air quality (IAQ) issues has led to the increased use of more effective air filters in residential heating and cooling systems. A drawback of improved filtration is that better filters tend to have more flow resistance. This can lead to lower system airflows that reduce heat exchanger efficiency, increase duct pressure that leads to increased air leakage for ducts and, in some case s, increased blower power consumption. There is currently little knowledge on the magnitude of these effects. In this study, the performance of ten central forced air systems was monitored for a year. The systems used either a Permanent Split Capacitor (PSC) or a Brushless Permanent Magnet (BPM) blower. Each system was operated with a range of filter efficiencies ranging from MERV 6 (the lowest currently permitted in ASHRAE Standard 62.2) up to MERV 16. Measurements were recorded every ten seconds for blower power, filter pressure drop, supply and return plenum pressures together with plenum and indoor temperatures. These detailed continuous measurements allowed observation of filter loading effects as well as the initial change in system performance when filters were swapped. The results of the field measurements were used in simulations to examine more general system performance effects for a wider range of climates. The field tests showed that system static pressures were highly influenced by filter selection, filter loading rates varied more from house to house than by MERV rating and overall were quite low in many of the homes. PSC motors showed reduced power and airflow as the filters loaded, but BPM motors attempted to maintain a constant airflow and increased their power to do so. The combined field test and simulation results from this study indicate that for MERV 10-13 filters the effects on energy use are small (5%) and usability. In systems using low MERV filters that are already close to blower performance limits the addition of a MERV 16 filter pushed the blowers to their performance limits.

Measure Guideline: Selecting Ventilation Systems for Existing Homes  

SciTech Connect (OSTI)

This document addresses adding -or improving - mechanical ventilation systems to existing homes. The purpose of ventilation is to remove contaminants from homes, and this report discusses where, when, and how much ventilation is appropriate in a home, including some discussion of relevant codes and standards. Advantages, disadvantages, and approximate costs of various system types are presented along with general guidelines for implementing the systems in homes. CARB intends for this document to be useful to decision makers and contractors implementing ventilation systems in homes. Choosing the "best" system is not always straightforward; selecting a system involves balancing performance, efficiency, cost, required maintenance, and several other factors. It is the intent of this document to assist contractors in making more informed decisions when selecting systems. Ventilation is an integral part of a high-performance home. With more air-sealed envelopes, a mechanical means of removing contaminants is critical for indoor environmental quality and building durability.

Evaluating Ventilation Systems for Existing Homes  

SciTech Connect (OSTI)

During the course of this project, an affordable and high performance ductwork system to directly address the problems of thermal losses, poor efficiency, and air leakage was designed. To save space and enable direct connections between different floors of the building, the ductwork system was designed in such a way that it occupied interior or exterior frame wall cavities. The ductwork system satisfied building regulations for structural support when bridging multiple floors, the spread of fire and smoke, and insulation to reduce the heat flow into or out of the building. Retrofits of urban residential buildings will be the main focus for the application of this ductwork system. Highly reflective foils and insulating materials were used to aid in the increase of the overall R-value of the ductwork itself and the wall assembly. It is expected that the proposed system will increase the efficiency of the HVAC system and the thermal resistance of the building envelope. The performance of the proposed ductwork design was numerically evaluated in a number of different ways. Our results indicate that the duct method is a very cost attractive alternative to the conventional method.

Thermo-economic assessment of end user value in home and community scale renewable energy systems  

Science Journals Connector (OSTI)

This study employs thermo-economic analysis to establish a homeowner-centric valuation of renewable energy technologies. The evaluation methodology is illustrated using several classes of renewable energy technology including ground-source heat pumps wind turbines photovoltaic panels and solar thermal water heaters. Energy systems employing each of these technologies are examined when servicing the typical domestic energy loads of a single-detached home. Through the analysis it is learned that single-home photovoltaic systems produce energy at an annual cost approximately four times that of grid electricity while wind energy systems deliver this energy at approximately twice the cost of grid electricity. Further single-detached homeowners currently heating with fuel oil and/or grid electricity may expect to save between $1000 and $1800 per year when switching to a ground-source heat pump system; whereas those considering the implementation of a solar thermal water heater can expect to spend an additional $245 per year for hot water. Investigation of larger scale renewable systems examined the performance of wind turbines and ground-source heat pumps when serving groups of single-detached homes; wind turbines were found to exhibit significant economies of scale.

A ground-coupled storage heat pump system with waste heat recovery  

SciTech Connect (OSTI)

This paper reports on an experimental single-family residence that was constructed to demonstrate integration of waste heat recovery and seasonal energy storage using both a ventilating and a ground-coupled heat pump. Called the Idaho energy Conservation Technology House, it combines superinsulated home construction with a ventilating hot water heater and a ground coupled water-to-water heat pump system. The ground heat exchangers are designed to economically promote seasonal and waste heat storage. Construction of the house was completed in the spring of 1989. Located in Moscow, Idaho, the house is occupied by a family of three. The 3,500 ft{sup 2} (325 m{sup 2}) two-story house combines several unique sub-systems that all interact to minimize energy consumption for space heating and cooling, and domestic hot water.

Underground Mine Water Heating and Cooling Using Geothermal Heat Pump Systems  

SciTech Connect (OSTI)

In many regions of the world, flooded mines are a potentially cost-effective option for heating and cooling using geothermal heat pump systems. For example, a single coal seam in Pennsylvania, West Virginia, and Ohio contains 5.1 x 1012 L of water. The growing volume of water discharging from this one coal seam totals 380,000 L/min, which could theoretically heat and cool 20,000 homes. Using the water stored in the mines would conservatively extend this option to an order of magnitude more sites. Based on current energy prices, geothermal heat pump systems using mine water could reduce annual costs for heating by 67% and cooling by 50% over conventional methods (natural gas or heating oil and standard air conditioning).

Chapter 5 - Solar Water-Heating Systems  

Science Journals Connector (OSTI)

Abstract Chapter 5 is on solar water-heating systems. Both passive and active systems are described. Passive systems include thermosiphon and integrated collector storage systems. The former include theoretical performance of thermosiphon solar water heaters, reverse circulation in thermosiphon systems, vertical against horizontal tank configurations, freeze protection, and tracking thermosiphons. Subsequently, active systems are described, which include direct circulation systems, indirect water-heating systems, air water-heating systems, heat pump systems and pool heating systems, which include the analysis of various heat losses like evaporation, radiation, convection heat losses, make-up water load, and solar radiation-heat gain. Then the characteristics and thermal analysis of heat storage systems for both water and air systems are presented. The module and array design methods are then described and include the effects of shading, thermal expansion, galvanic corrosion, array sizing, heat exchangers, pipe and duct losses, partially shaded collectors and over-temperature protectionfollowed by an analysis of the characteristics of differential thermostats. Finally, methods to calculate the hot water demand are given as well as a review of international standards used to evaluate the solar water heaters performance. The chapter includes also simple system models and practical considerations for the setup of solar water-heating systems, which include: pipes, supports and insulation; pumps; valves and instrumentation.

The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: Final Report  

SciTech Connect (OSTI)

This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

Warm homes: Drivers of the demand for heating in the residential sector in New Zealand  

Science Journals Connector (OSTI)

New Zealand houses are large, often poorly constructed and heated, by OECD standards, and consequently are colder and damper indoors than recommended by the World Health Organisation. This affects both the energy consumption and the health of households. The traditional New Zealand household pattern of only heating one room of the house has been unchanged for decades, although there has been substantial market penetration of unflued gas heaters and more recently heat pumps. This paper describes the residential sector and the results of two community-based trials of housing and heating interventions that have been designed to measure the impact of (1) retrofitting insulation and (2) replacing unflued gas heaters and electric resistance heaters with heat pumps, wood pellet burners and flued gas heaters. The paper describes findings on the rebound effect or take-backthe extent to which households take the gains from insulation and heating improvements as comfort (higher temperatures) rather than energy savings, and compares energy-saving patterns with those suggested by an earlier study. Findings on these aspects of household space heating are discussed in the context of the New Zealand government's policy drive for a more sustainable energy system, and the implications for climate change policy.

Water and Energy Savings using Demand Hot Water Recirculating Systems in Residential Homes: A Case Study of Five Homes in Palo Alto, California  

SciTech Connect (OSTI)

This report summarizes a preliminary study aimed at estimating the potential of saving potable water, (and the electrical energy used to heat it), that is presently lost directly to the drain while occupants wait for hot water to arrive at the faucet (point of use). Data were collected from five single-family homes in Palo Alto, California. Despite the small sample size in this study, the results make a compelling case for retrofitting homes with hot water recirculation systems to eliminate unnecessary wastage of water at the point of use. Technical as well as behavioral and attitudinal changes towards water conservation are necessary for a fulfilling and successful conservation effort. This report focuses on the technical issues, but behavioral issues are also noted, which may be factored into future studies involving local and state governments and utility companies.

The two programs discussed in this report deal with the use of organic Rankine cycle systems as a means of producing electrical or mechanical power from energy in industrial processes' exhaust. Both programs deal with the design, development, demonstration, and economic evaluation of a 600kWe organic Rankine cycle system designed to recover energy from the exhaust of industrial processes with exhaust gas temperatures of 600/sup 0/F or above. The work done has, through the successful operation of the units installed, demonstrated the technical feasibility of utilizing an organic Rankine cycle bottoming system as a means of conserving energy through waste heat utilization. Continued operation at several sites has also demonstrated the soundness of the design, overall system reliability, and low operating cost. In addition, the basis under which this technology is economically viable in industrial applications was established. As a result of market studies and experience gained from the application of the units addressed in this report, it is concluded that there is a significant market for the equipment at the installed cost level of $1200/kWe to $1500/kWe and that this goal is achievable in the proper manufacturing environment. 54 figs., 2 tabs.

A system for collecting activity annotations for home energy management  

Science Journals Connector (OSTI)

Abstract Home energy management is becoming increasingly important and, though there are a plethora of tools for accessing energy consumption data, few provide concrete insights that can directly help users manage demand. Mechanisms that enable a user to draw connections between activities and energy consumption by attaching contextual labels to energy events are a promising step; however solutions for collecting annotations from users can be error prone or intrusive. This work presents a system for collecting in situ annotations using a smartphone application coupled with an off-the-shelf home energy measurement infrastructure. We use a novel power profiling approach to identify important energy consumption events and solicit contextual annotations from the user via a push notification sent to a smartphone. Using a five-week study performed in five homes, we show that our power profiling approach can identify a significant percentage of important energy consumption events using a very small number of monitored devices. We were able to collect an average of over 2 annotations per day and while users provided a wide range of annotations, the motivation to provide annotations varied across subjects.

Designing, selecting and installing a residential ground-source heat pump system  

SciTech Connect (OSTI)

It's a compelling proposition: Use the near-constant-temperature heat underground to heat and cool your home and heat domestic water, slashing your energy bills. Yet despite studies demonstrating significant energy savings from ground-source heat pump (GSHP) systems, their adoption has been hindered by high upfront costs. Fewer than 1% of US homes use a GSHP system. However, compared to a minimum-code-compliant conventional space-conditioning system, when properly designed and installed, a GSHP retrofit at current market prices offers simple payback of 4.3 years on national average, considering existing federal tax credits. Most people understand how air-source heat pumps work: they move heat from indoor air to outdoor air when cooling and from outdoor air to indoor air when heating. The ground-source heat pump operates on the same principle, except that it moves heat to or from the ground source instead of outdoor air. The ground source is usually a vertical or horiontal ground heat exchanger. Because the ground usually has a more favorable temperature than ambient air for the heating and cooling operation of the vapor-compression refrigeration cycle, GSHP sysems can operate with much higher energy efficiencies than air-source heat pump systems when properly designed and installed. A GSHP system used in a residual building typically provides space conditioning and hot water and comprises three major components: a water-source heat pump unit designed to operate at a wider range of entering fluid temperatures (typically from 30 F to 110 F, or 1 C to 43 C) than a conventional water-source heat pump unit; a ground heat exchanger (GHX); and distribution systems to deliver hot water to the storage tank and heating or cooling to the conditioned rooms. In most residual GSHP systems, the circulation pumps and associated valves are integrated with the heat pump to circulate the heat-carrier fluid (water or aqueous antifreeze solution) through the heat pump and the GHX. A recent assessment indicates that if 20% of US homes replaced their existing space-conditioning and water-heating systems with properly designed, installed and operated state-of-the-art GSHP systems, it would yield significant benefits each year. These include 0.8 quad British thermal units (Btu) of primary energy savings, 54.3 million metric tons of CO{sub 2} emission reductions, $10.4 billion in energy cost savings and 43.2 gigawatts of reduction in summer peak electrical demand.

Heat transfer analysis in Stirling engine heat input system  

SciTech Connect (OSTI)

One of the major factor in commercialization of Stirling engine is mass productivity, and the heat input system including tubular heater is one of the obstacles to mass production because of its complexity in shape and difficulty in manufacturing, which resulted from using oxidation-resistant, low-creep alloys which are not easy to machine and weld. Therefore a heater heat exchanger which is very simple in shape and easy to make has been devised, and a burner system appropriate to this heater also has been developed. In this paper specially devised heat input system which includes a heater shell shaped like U-cup and a flame tube located in the heater shell is analyzed in point of heat transfer processes to find optimum heat transfer. To enhance the heat transfer from the flame tube to the heater shell wall, it is required that the flame tube diameter be enlarged as close to the heater shell diameter as possible, and the flame tube temperature be raised as high as possible. But the enlargement of the flame tube diameter should be restricted by the state of combustion affected by hydraulic resistance of combustion gas, and the boost of the flame tube temperature should be considered carefully in the aspects of the flame tube`s service life.

This document addresses adding -or improving - mechanical ventilation systems to existing homes. The purpose of ventilation is to remove contaminants from homes, and this report discusses where, when, and how much ventilation is appropriate in a home, including some discussion of relevant codes and standards. Advantages, disadvantages, and approximate costs of various system types are presented along with general guidelines for implementing the systems in homes. CARB intends for this document to be useful to decision makers and contractors implementing ventilation systems in homes. Choosing the "best" system is not always straightforward; selecting a system involves balancing performance, efficiency, cost, required maintenance, and several other factors. It is the intent of this document to assist contractors in making more informed decisions when selecting systems. Ventilation is an integral part of a high-performance home. With more air-sealed envelopes, a mechanical means of removing contaminants is critical for indoor environmental quality and building durability.

A study of aggregation bias in estimating the market for home heating and cooling equipment  

SciTech Connect (OSTI)

Econometricians frequently propose parametric models which are contingent on an underlying assumption of rational economic agents maximizing their utility. Accurate estimation of the parameters of these models depends on using data disaggregated to the level of the actual agents, usually individual consumers or firms. Using data at some other level of aggregation introduces bias into the inferences made from the data. Unfortunately, properly disaggregated data is often unavailable, or at least, much more costly to obtain than aggregate data. Research on consumer choice of home heating equipment has long depended on state-level cross-sectional data. Only recently have investigators been able to build up and successfully use data on consumer attributes and choices at the household level. A study estimated for the Electric Power Research Institute REEPS model is currently one of the best of these. This paper examines the degree of bias that would be introduced in that study if only average data across SMSAs or states were used at several points in the investigation. We examine the market shares and elasticities estimated from that model using only the mean values of the exogenous variables, and find severe errors to be possible. However, if the models were calibrated on only aggregate data originally, we find that proper treatment allows market shares and elasticities to be found with little error relative to the disaggregate models. 22 refs., 4 figs., 10 tabs.

ENERGY ABSORBER HEAT PUMP SYSTEM TO SUPPLEMENT HEAT RECOVERY SYSTEMS IN AN INDOOR SWIMMING POOL  

Science Journals Connector (OSTI)

ABSTRACT Compared with convontional indoor swimming pools with traditional plant engineering, the Schwalmtal indoor swimming pool has a final energy consumption of just 40%. This low consumption is achieved by improved insulation of the building's enveloping surface, through the operation of systems for the recovery of heat from drain water and waste air as well as by the operation of a heat pump system to gain ambient heat. The decentralised heat recovery systems met between 40 and 80% of the heat requirements in the supply areas where they were used. The electric heat pump system, which is operated in the bivalent mode in parallel to a heating boiler, could generate 75% of the heat provided by the central heating circuit to meet the residual heat requirements. The report illustrates the structure of the residual heat requirements of the central heating circuit. A description is given of the measured coefficients of performance of the brine/water heat pump connected by a brine circuit with two different energy absorber types - energy stack and energy roof. Finally, the ambient energy gained with the absorbers is broken down into the various kinds of heat gains from radiation, convection, condensation etc. KEYWORDS Energy absorber; energy stack; energy roof; heat pump; heat recovery systems; indoor swimming pool; energy engineering concept.

Exergoeconomic evaluation on the optimum heating circuit system of Simav geothermal district heating system  

Science Journals Connector (OSTI)

Simav is one of the most important 15 geothermal areas in Turkey. It has several geothermal resources with the mass flow rate ranging from 35 to 72kg/s and temperature from 88 to 148C. Hence, these geothermal resources are available to use for several purposes, such as electricity generation, district heating, greenhouse heating, and balneological purposes. In Simav, the 5000 residences are heated by a district heating system in which these geothermal resources are used. Beside this, a greenhouse area of 225,000m2 is also heated by geothermal. In this study, the working conditions of the Simav geothermal district heating system have been optimized. In this paper, the main characteristics of the system have been presented and the impact of the parameters of heating circuit on the system are investigated by the means of energy, exergy, and life cycle cost (LCC) concepts. As a result, the optimum heating circuit has been determined as 60/49C.

An Analysis of the Effects of Residential Photovoltaic Energy Systems on Home Sales Prices in California  

SciTech Connect (OSTI)

An increasing number of homes in the U.S. have sold with photovoltaic (PV) energy systems installed at the time of sale, yet relatively little research exists that estimates the marginal impacts of those PV systems on home sale prices. A clearer understanding of these possible impacts might influence the decisions of homeowners considering the installation of a PV system, homebuyers considering the purchase of a home with PV already installed, and new home builders considering including PV as an optional or standard product on their homes. This research analyzes a large dataset of California homes that sold from 2000 through mid-2009 with PV installed. It finds strong evidence that homes with PV systems sold for a premium over comparable homes without PV systems during this time frame. Estimates for this premium expressed in dollars per watt of installed PV range, on average, from roughly $4 to $5.5/watt across a large number of hedonic and repeat sales model specifications and robustness tests. When expressed as a ratio of the sales price premium of PV to estimated annual energy cost savings associated with PV, an average ratio of 14:1 to 19:1 can be calculated; these results are consistent with those of the more-extensive existing literature on the impact of energy efficiency on sales prices. When the data are split among new and existing homes, however, PV system premiums are markedly affected. New homes with PV show premiums of $2.3-2.6/watt, while existing homes with PV show premiums of more than $6/watt. Reasons for this discrepancy are suggested, yet further research is warranted. A number of other areas where future research would be useful are also highlighted.

Dynamics of heat transfer between nano systems  

E-Print Network [OSTI]

We develop a dynamical theory of heat transfer between two nano systems. In particular, we consider the resonant heat transfer between two nanoparticles due to the coupling of localized surface modes having a finite spectral width. We model the coupled nanosystem by two coupled quantum mechanical oscillators, each interacting with its own heat bath, and obtain a master equation for the dynamics of heat transfer. The damping rates in the master equation are related to the lifetimes of localized plasmons in the nanoparticles. We study the dynamics towards the steady state and establish connection with the standard theory of heat transfer in steady state. For strongly coupled nano particles we predict Rabi oscillations in the mean occupation number of surface plasmons in each nano particle.

Effects of Medicare payment reform: Evidence from the home health interim and prospective payment systems  

Science Journals Connector (OSTI)

Abstract Medicare continues to implement payment reforms that shift reimbursement from fee-for-service toward episode-based payment, affecting average and marginal payment. We contrast the effects of two reforms for home health agencies. The home health interim payment system in 1997 lowered both types of payment; our conceptual model predicts a decline in the likelihood of use and costs, both of which we find. The home health prospective payment system in 2000 raised average but lowered marginal payment with theoretically ambiguous effects; we find a modest increase in use and costs. We find little substantive effect of either policy on readmissions or mortality.

Design Approach and Performance Analysis of a Small Integrated Heat Pump (IHP) for Net Zero Energy Homes (ZEH)  

SciTech Connect (OSTI)

This paper describes the design and performance analysis of a variable-capacity heat pump system developed for a small [1800ft2 (167 m2)] prototype net ZEH with an average design cooling load of 1.25 tons (4.4 kW) in five selected US climates. The heat pump integrates space heating and cooling, water heating, ventilation, and humidity control (humidification and dehumidification) functions into a single integrated heat pump (IHP) unit. The design approach uses one small variable-capacity compressor to meet all the above functions in an energy efficient manner. Modal performance comparisons to an earlier IHP product are shown relative to the proposed new design for net ZEH application. The annual performance analysis approach using TRNSYS in conjunction with the ORNL Heat Pump Design Model is discussed. Annual performance projections for a range of locations are compared to those of a base system consisting of separate pieces of equipment to perform the same functions. The ZEH IHP is projected to reduce energy use for space heating & cooling, water heating, dehumidification, and ventilation for a net ZEH by about 50% compared to that of the base system.

Experimental study of a photovoltaic solar-assisted heat-pump/heat-pipe system  

Science Journals Connector (OSTI)

A practical design for a heat pump with heat-pipe photovoltaic/thermal (PV/T) collectors is presented. The hybrid system is called the photovoltaic solar-assisted heat-pump/heat-pipe (PV-SAHP/HP) system. To focus on both actual demand and energy savings, the PV-SAHP/HP system was designed to be capable of operating in three different modes, namely, the heat-pipe, solar-assisted heat pump, and air-source heat-pump modes. Based on solar radiation, the system operates in an optimal mode. A series of experiments were conducted in Hong Kong to study the performance of the system when operating in the heat-pipe and the solar-assisted heat-pump modes. Moreover, energy and exergy analyses were used to investigate the total PV/T performance of the system.

Heat flux dynamics in dissipative cascaded systems  

E-Print Network [OSTI]

We study the dynamics of heat flux in the thermalization process of a pair of identical quantum system that interact dissipatively with a reservoir in a {\\it cascaded} fashion. Despite the open dynamics of the bipartite system S is globally Lindbladian, one of the subsystems "sees" the reservoir in a state modified by the interaction with the other subsystem and hence it undergoes a non-Markovian dynamics. As a consequence, the heat flow exhibits a non-exponential time behaviour which can greatly deviate from the case where each party is independently coupled to the reservoir. We investigate both thermal and correlated initial states of $S$ and show that the presence of correlations at the beginning can considerably affect the heat flux rate. We carry out our study in two paradigmatic cases -- a pair of harmonic oscillators with a reservoir of bosonic modes and two qubits with a reservoir of fermionic modes -- and compare the corresponding behaviours. In the case of qubits and for initial thermal states, we find that the trace distance discord is at any time interpretable as the correlated contribution to the total heat flux.

Warren Estates-Manzanita Estates Reno, Nevada residential geothermal district heating system  

SciTech Connect (OSTI)

Warren Estates-Manzanita Estates is the largest privately-owned and operated residential geothermal district heating system in the State of Nevada. The system has operated for ten years and presently services 95 homes. Geothermal energy is used to heat homes, domestic water, spas, swimming pools, and greenhouses. Four homes have installed driveway deicing systems using geothermal energy. This paper briefly describes the geothermal resource, wells, system engineering, operation, applications, and economics. The accompanying posters illustrate the geothermal area, system design, and various applications. The resource is part of the Moana geothermal field, located in southwest Reno. Excluding the Warren-Manzanita Estates, the well-known Moana field supports nearly 300 geothermal wells that supply fluids to individual residences, several motels, a garden nursery, a few churches, and a municipal swimming pool. The Warren-Manzanita Estates is ideally suited for residential district space heating because the resource is shallow, moderate-temperature, and chemically benign. The primary reservoir rock is the Kate Peak andesite, a Tertiary volcanic lahar that has excellent permeability within the narrow fault zones that bisect the property. The Kate Peak formation is overlain by impermeable Tertiary lake sediments and alluvium. Two production wells, each about 240 m deep, are completed near the center of the residential development at the intersection of two fault zones. Geothermal fluids are pumped at a rate of 15 to 25 l/s (260-400 gpm) from one of two wells at a temperature of 95{degrees}C (202{degrees}F) to two flat-plate heat exchangers. The heat exchangers transfer energy from the geothermal fluids to a second fluid, much like a binary geothermal power plant.

Heat exchanger optimization for geothermal district heating systems: A fuel saving approach  

Science Journals Connector (OSTI)

One of the most commonly used heating devices in geothermal systems is the heat exchanger. The output conditions of heat exchangers are based on several parameters. The heat transfer area is one of the most important parameters for heat exchangers in terms of economics. Although there are a lot of methods to optimize heat exchangers, the method described here is a fairly easy approach. In this paper, a counter flow heat exchanger of geothermal district heating system is considered and optimum design values, which provide maximum annual net profit, for the considered heating system are found according to fuel savings. Performance of the heat exchanger is also calculated. In the analysis, since some values are affected by local conditions, Turkey's conditions are considered.

Insights into the design, use and implementation of home energy management systems  

Science Journals Connector (OSTI)

Between 2008 and 2011, three different home energy management systems (HEMS) that give feedback on energy consumption were implemented in households in the Netherlands. Home energy management systems are defined as intermediary devices that can visualise, monitor and/or manage domestic gas and/or electricity consumption. Through a series of questionnaires, interviews, focus groups and usability tests, a wide range of knowledge was gathered on factors influencing the effectiveness of the three systems. The resulting insights were structured with the help of a conceptual model, which outlines the various interactions between users, energy monitors, and their social and physical environments. The insights provide a broad spectrum of factors to be considered for the successful design and implementation of home energy management systems. This paper aims to provoke an open discussion to ascertain the value of the different factors and further the development of effective and useful HEMS.

Comparison of an impedance heating system to mineral insulated heat trace for power tower applications  

SciTech Connect (OSTI)

A non-conventional type of heating system is being tested at Sandia National Laboratories for solar thermal power tower applications. In this system, called impedance heating, electric current flows directly through the pipe to maintain the desired temperature. The pipe becomes the resistor where the heat is generated. Impedance heating has many advantages over previously used mineral insulated (MI) heat trace. An impedance heating system should be much more reliable than heat trace cable since delicate junctions and cabling are not used and the main component, a transformer, is inherently reliable. A big advantage of impedance heating is the system can be sized to rapidly heat up the piping to provide rapid response times necessary in cyclic power plants such as solar power towers. In this paper, experimental results from testing an impedance heating system are compared to MI heat trace. The authors found impedance heating was able to heat piping rapidly and effectively. There were not significant stray currents and impedance heating did not affect instrumentation.

SciTech Connect (OSTI)

To improve the system performance of the GHP, modeling and experimental study has been made by using desiccant system in cooling operation (particularly in high humidity operations) and suction line waste heat recovery to augment heating capacity and efficiency. The performance of overall GHP system has been simulated by using ORNL Modulating Heat Pump Design Software, which is used to predict steady-state heating and cooling performance of variable-speed vapor compression air-to-air heat pumps for a wide range of operational variables. The modeling includes: (1) GHP cycle without any performance improvements (suction liquid heat exchange and heat recovery) as a baseline (both in cooling and heating mode), (2) the GHP cycle in cooling mode with desiccant system regenerated by waste heat from engine incorporated, (3) GHP cycle in heating mode with heat recovery (recovered heat from engine). According to the system modeling results, by using desiccant system regenerated by waste heat from engine, the SHR can be lowered to 40%. The waste heat of the gas engine can boost the space heating efficiency by 25% in rated operating conditions.

Simulation study on supply temperature optimization in domestic heat pump systems  

Science Journals Connector (OSTI)

An air-to-water heat pump system for the heating of a one-family home is numerically analysed. The influence of the supply temperature on the seasonal performance factor of the heating system is examined by varying the heating curve. Furthermore, an adaptive control algorithm is studied which lowers the supply temperature according to the actual heating demand. The study includes a variation of control parameters. The different configurations are evaluated with respect to their efficiency (seasonal performance factor) and the comfort (room temperature). In systems with correctly parametrized heating curve controlling the room temperature is likely to be too high because of inner loads and solar gains. Instead of dealing with these gains by lowering the mass flow using thermostatic valves, the supply temperature can be dropped. This has a positive effect on heat pump efficiency because it decreases the total temperature lift. The control algorithm adapts the supply temperature in discrete time steps depending on the position of the thermostatic valve. Special attention has to be paid for the resulting room temperature and its deviation. With the control algorithm presented in this paper, the seasonal performance factor can be increased by up to 0.19, depending on the allowed variability of room temperature. Savings in annual primary energy demand compared to a standard controlling are up to 6.8%.

Demonstration and Performance Monitoring of Foundation Heat Exchangers (FHX) in Ultra-High Energy Efficient Research Homes  

SciTech Connect (OSTI)

The more widespread use of Ground Source Heat Pump (GSHP) systems has been hindered by their high first cost, which is mainly driven by the cost of the drilling and excavation for installation of ground heat exchangers (GHXs). A new foundation heat exchanger (FHX) technology was proposed to reduce first cost by placing the heat exchanger into the excavations made during the course of construction (e.g., the overcut for the basement and/or foundation and run-outs for water supply and the septic field). Since they reduce or eliminate the need for additional drilling or excavation, foundation heat exchangers have the potential to significantly reduce or eliminate the first cost premium associated with GSHPs. Since December 2009, this FHX technology has been demonstrated in two ultra-high energy efficient new research houses in the Tennessee Valley, and the performance data has been closely monitored as well. This paper introduces the FHX technology with the design, construction and demonstration of the FHX and presents performance monitoring results of the FHX after one year of monitoring. The performance monitoring includes hourly maximum and minimum entering water temperature (EWT) in the FHX compared with the typical design range, temperature difference (i.e., T) across the FHX, and hourly heat transfer rate to/from the surrounding soil.

A new cascade-type heat conversion system  

SciTech Connect (OSTI)

Various heat conversion systems have different operating temperatures. This paper shows how, in a solar energy system some of the waste heat from a thermophotovoltaic arrangement can be made to operate a thermionic power generator. The waste heat of the thermionic power generator can then be made to operate an alkali-metal thermal electric converter, and the waste heat from the alkali-metal thermal electric converter as well as the rest of the waste heat of the thermophotovoltaic system can be made to operate a methane reformation system. Stored heat from the methane reformation system can be made to operate the system at night. The overall system efficiency of the example shown is 42.6%. As a prime source of heat a nuclear pile or burning hydrogen may be used.

Energy Efficient Integration of Heat Pumps into Solar District Heating Systems with Seasonal Thermal Energy Storage  

Science Journals Connector (OSTI)

Abstract Solar district heating (SDH) with seasonal thermal energy storage (STES) is a technology to provide heat for space heating and domestic hot water preparation with a high fraction of renewable energy. In order to improve the efficiency of such systems heat pumps can be integrated. By preliminary studies it was discovered, that the integration of a heat pump does not always lead to improvements from an overall energy perspective, although the operation of the heat pump increases the efficiency of other components of the system e. g. the STES or the solar collectors. Thus the integration of heat pumps in SDH systems was investigated in detail. Usually, the heat pumps are integrated in such a way, that the STES is used as low temperature heat source. No other heat sources from the ambience are used and only that amount of energy consumed by the heat pump is additionally fed into the system. In the case of an electric driven heat pump, this is highly questionable concerning economic and CO2-emission aspects. Despite that fact the operation of the heat pump influences positively the performance of other components in the system e. g. the STES and makes them more efficient. If the primary energy consumption of the heat pump is lower than the energetic benefits of all other components, the integration makes sense from an energetic point of view. A detailed assessment has been carried out to evaluate the most promising system configurations for the integration of a heat pump. Based on this approach a system concept was developed in which the integration of the heat pump is energetically further improved compared to realised systems. By means of transient system simulations this concept was optimised with regard to the primary energy consumption. A parameter study of this new concept has been performed to identify the most sensitive parameters of the system. The main result and conclusion are that higher solar fractions and also higher primary energy savings can be achieved by SDH systems using heat pumps compared systems without heat pumps.

Implementing and Evaluating a Wireless Body Sensor System for Automated Physiological Data Acquisition at Home  

E-Print Network [OSTI]

Advances in embedded devices and wireless sensor networks have resulted in new and inexpensive health care solutions. This paper describes the implementation and the evaluation of a wireless body sensor system that monitors human physiological data at home. Specifically, a waist-mounted triaxial accelerometer unit is used to record human movements. Sampled data are transmitted using an IEEE 802.15.4 wireless transceiver to a data logger unit. The wearable sensor unit is light, small, and consumes low energy, which allows for inexpensive and unobtrusive monitoring during normal daily activities at home. The acceleration measurement tests show that it is possible to classify different human motion through the acceleration reading. The 802.15.4 wireless signal quality is also tested in typical home scenarios. Measurement results show that even with interference from nearby IEEE 802.11 signals and microwave ovens, the data delivery performance is satisfactory and can be improved by selecting an appropriate channe...

Control valve for solar heating systems  

SciTech Connect (OSTI)

A control valve for a solar heating system is disclosed. The valve has a valve body which defines four chambers disposed end to end. A valve operating rod is movable axially through all four chambers under motor control and carries a valve member for directing liquid through the valve. In one position of the valve member, incoming liquid is directed to an outlet for connection to a solar collector and liquid returning from the collector can flow through the valve body and back to the swimming pool. In the other position of the valve member, the liquid bypasses the collector and is directed back to the pool while liquid in the collector drains back into the valve body through the outlet and is removed by suction from a drain-down chamber in the valve body.

ABSTRACT This paper describes the design and the first preliminary performance results of a sunspace attached to an existent building, combined with a heatpump and a long term heat storage. The aim of the project is to study the possibility of storing the excess heat of the passive system in a low temperature storage, which is used as cold source for a heatpump. The advantages of the presented system are that the energy flows in the passive solar system can be controlled and that a rather high solar fraction can be obtained (around .7 to .8 in the climate of Ispra).

Chemical heat pump and chemical energy storage system  

DOE Patents [OSTI]

A chemical heat pump and storage system employs sulfuric acid and water. In one form, the system includes a generator and condenser, an evaporator and absorber, aqueous acid solution storage and water storage. During a charging cycle, heat is provided to the generator from a heat source to concentrate the acid solution while heat is removed from the condenser to condense the water vapor produced in the generator. Water is then stored in the storage tank. Heat is thus stored in the form of chemical energy in the concentrated acid. The heat removed from the water vapor can be supplied to a heat load of proper temperature or can be rejected. During a discharge cycle, water in the evaporator is supplied with heat to generate water vapor, which is transmitted to the absorber where it is condensed and absorbed into the concentrated acid. Both heats of dilution and condensation of water are removed from the thus diluted acid. During the discharge cycle the system functions as a heat pump in which heat is added to the system at a low temperature and removed from the system at a high temperature. The diluted acid is stored in an acid storage tank or is routed directly to the generator for reconcentration. The generator, condenser, evaporator, and absorber all are operated under pressure conditions specified by the desired temperature levels for a given application. The storage tanks, however, can be maintained at or near ambient pressure conditions. In another form, the heat pump system is employed to provide usable heat from waste process heat by upgrading the temperature of the waste heat.

Analyzing the efficiency of a heat pump assisted drain water heat recovery system that uses a vertical inline heat exchanger  

Science Journals Connector (OSTI)

Abstract The purpose of the present study is to accumulate knowledge on how a drain water heat recovery system using a vertical inline heat exchanger and a heat pump performs under different drain water flow profile scenarios. Investigating how the intermittent behavior of the drain water influences the performance for this type of system is important because it gives insight on how the system will perform in a real life situation. The scenarios investigated are two 24h drain water flow rate schedules and one shorter schedule representing a three minute shower. The results from the present paper add to the knowledge on how this type of heat recovery system performs in a setting similar to a multi-family building and how sizing influences the performance. The investigation shows that a heat recovery system of this type has the possibility to recover a large portion of the available heat if it has been sized to match the drain water profile. Sizing of the heat pump is important for the system performance; sizing of the storage tank is also important but not as critical.

Heat recovery and the economizer for HVAC systems  

SciTech Connect (OSTI)

This articles examines why a combined heat reclaim/economizer system with priority to heat reclaim operation is most likely to result in the least annual total HVAC energy. PC-based, hour-by-hour simulation programs evaluate annual HVAC energy requirements when using combined operation of heat reclaim and economizer cycle, while giving priority to operation of either one. These simulation programs also enable the design engineer to select the most viable heat reclaim and/or economizer system for any given type of HVAC system serving the building internal load level, building geographical location and other building/system variables.

Method of measuring heat influx of a cryogenic transfer system  

DOE Patents [OSTI]

A method is provided for measuring the heat influx of a cryogenic transfer system. A gaseous phase of the cryogen used during normal operation of the system is passed through the system. The gaseous cryogen at the inlet to the system is tempered to duplicate the normal operating temperature of the system inlet. The temperature and mass flow rate of the gaseous cryogen is measured at the outlet of the system, and the heat capacity of the cryogen is determined. The heat influx of the system is then determined from known thermodynamic relationships.

AMBIPOLAR DIFFUSION HEATING IN TURBULENT SYSTEMS  

SciTech Connect (OSTI)

The temperature of the gas in molecular clouds is a key determinant of the characteristic mass of star formation. Ambipolar diffusion (AD) is considered one of the most important heating mechanisms in weakly ionized molecular clouds. In this work, we study the AD heating rate using two-fluid turbulence simulations and compare it with the overall heating rate due to turbulent dissipation. We find that for observed molecular clouds, which typically have Alfven Mach numbers of {approx}1 and AD Reynolds numbers of {approx}20, about 70% of the total turbulent dissipation is in the form of AD heating. AD has an important effect on the length scale where energy is dissipated: when AD heating is strong, most of the energy in the cascade is removed by ion-neutral drift, with a comparatively small amount of energy making it down to small scales. We derive a relation for the AD heating rate that describes the results of our simulations to within a factor of two. Turbulent dissipation, including AD heating, is generally less important than cosmic-ray heating in molecular clouds, although there is substantial scatter in both.

Solar Assisted Heat Pump Systems with Ground Heat Exchanger Simulation Studies  

Science Journals Connector (OSTI)

Abstract Different concepts of solar assisted heat pump systems with ground heat exchanger are simulated according to IEA SHC Task44/HPP Annex38 reference conditions. Two aspects of the concepts are investigated using TRNSYS simulations. First, the solar impact on system efficiency is assessed by the seasonal performance factor. Second, the solar impact on the possible shortening of the ground heat exchanger is evaluated by the minimum temperature at the ground heat exchanger inlet. The simulation results reveal diverging optimums for the concepts. The direct use of solar energy clearly achieves the best effect on the efficiency improvement. A simple domestic hot water system reaches a seasonal performance factor of 4.5 and solar combi-systems seasonal performance factors up to 6. In contrast, the use of solar energy on the cold side of the heat pump achieves the best effects on the shortening of the ground heat exchanger of up to 20%. Two highly sensitive influences are investigated with the developed transient system model. First, the minimum allowed heat source temperature is varied. Here 1K equals a variation of 0.25 in the seasonal performance or of around 10% ground heat exchanger length. Second, the ground heat exchanger model is simulated without and with a pre-pipe that improves the transient model behavior. The influence of this pre-pipe on the SPF is small for conventionally designed ground heat exchangers, but of around 2K for the minimum inlet temperature. Therefore, the dynamic model quality reveals potential to reduce the size of the ground heat exchanger corresponding to investment costs.

RTO heat recovery system decreases production costs and provides payback  

SciTech Connect (OSTI)

Application of a heat recovery system to an existing regenerative thermal oxidizer (RTO) was considered, tested, and selected for decreasing production costs at a pressure sensitive tape manufacturing facility. Heat recovery systems on RTO's are less common than those on other thermal oxidizers (e.g., recuperative) because RTO's, by the nature of the technology, usually provide high thermal efficiencies (without the application of external heat recovery systems). In this case, the production processes were integrated with the emission controls by applying an external heat recovery system and by optimizing the design and operation of the existing drying and cure ovens, RTO system, and ductwork collection system. Integration of these systems provides an estimated annual production cost savings of over $400,000 and a simplified capital investment payback of less than 2 years, excluding possible savings from improved dryer operations. These additional process benefits include more consistent and simplified control of seasonal dryer performance and possibly production throughput increases. The production costs savings are realized by substituting excess RTO heat for a portion of the infrared (IR) electrical heat input to the dryers/ovens. This will be accomplished by preheating the supply air to the oven zones with the excess RTO heat (i.e., heat at the RTO exceeding auto-thermal conditions). Several technologies, including direct air-to-air, indirect air-to-air, hot oil-to-air, waste heat boiler (steam-to-air) were evaluated for transferring the excess RTO heat (hot gas) to the ovens. A waste heat boiler was selected to transfer the excess RTO heat to the ovens because this technology provided the most economical, reliable, and feasible operation. Full-scale production test trials on the coating lines were performed and confirmed the IR electrical costs could be reduced up to 70%.

Field application of a chemical heat and nitrogen generating system  

SciTech Connect (OSTI)

Heat is often required to stimulate production in wells with recurrent histories of paraffin deposition and plugging. A chemical system which produces heat and nitrogen at a predetermined well depth is proposed as an alternative to the traditional hot oil and steam generation treatments. The system is described briefly and case histories are given for 3 wells in California and 5 wells in Wyoming. The field results indicate that heat produced by the nitrogen generating system effectively stimulates production from paraffin plugged wells. The heat and nitrogen generating system further shows increased production cycle lengths over those which result from hot oil or paraffin solvent treatments. Beneficial effects of including a paraffin inhibitor in the treatment design are discussed, along with other potential applications for the heat produced by this system.

Life cycle assessment of base-load heat sources for district heating system options  

SciTech Connect (OSTI)

Purpose There has been an increased interest in utilizing renewable energy sources in district heating systems. District heating systems are centralized systems that provide heat for residential and commercial buildings in a community. While various renewable and conventional energy sources can be used in such systems, many stakeholders are interested in choosing the feasible option with the least environmental impacts. This paper evaluates and compares environmental burdens of alternative energy source options for the base load of a district heating center in Vancouver, British Columbia (BC) using the life cycle assessment method. The considered energy sources include natural gas, wood pellet, sewer heat, and ground heat. Methods The life cycle stages considered in the LCA model cover all stages from fuel production, fuel transmission/transportation, construction, operation, and finally demolition of the district heating system. The impact categories were analyzed based on the IMPACT 2002+ method. Results and discussion On a life-cycle basis, the global warming effect of renewable energy options were at least 200 kgeqCO2 less than that of the natural gas option per MWh of heat produced by the base load system. It was concluded that less than 25% of the upstream global warming impact associated with the wood pellet energy source option was due to transportation activities and about 50% of that was resulted from wood pellet production processes. In comparison with other energy options, the wood pellets option has higher impacts on respiratory of inorganics, terrestrial ecotoxicity, acidification, and nutrification categories. Among renewable options, the global warming impact of heat pump options in the studied case in Vancouver, BC, were lower than the wood pellet option due to BC's low carbon electricity generation profile. Ozone layer depletion and mineral extraction were the highest for the heat pump options due to extensive construction required for these options. Conclusions Natural gas utilization as the primary heat source for district heat production implies environmental complications beyond just the global warming impacts. Diffusing renewable energy sources for generating the base load district heat would reduce human toxicity, ecosystem quality degradation, global warming, and resource depletion compared to the case of natural gas. Reducing fossil fuel dependency in various stages of wood pellet production can remarkably reduce the upstream global warming impact of using wood pellets for district heat generation.

The results of the demonstration programme [open quotes]Efficient Use of Energy in Swimming Pool Construction[close quotes] has had a positive effect on the dissipation of solar systems for swimming pools. Infrared measurements show how a homogeneous flow can be achieved in the absorber field. The fact that solar systems are acceptable can be clearly in evidence that the behaviour of visitors to purely solar-heated pools with variable water temperature does not differ in principle from conventionally-heated pools with constant temperature. Economic considerations of the operation show that swimming pool solar systems are competitive with conventional heating systems.

High initial cost and lack of public awareness of ground source heat pump (GSHP) technology are the two major barriers preventing rapid deployment of this energy saving technology in the United States. Under the American Recovery and Reinvestment Act (ARRA), 26 GSHP projects have been competitively selected and carried out to demonstrate the benefits of GSHP systems and innovative technologies for cost reduction and/or performance improvement. This paper highlights findings of a case study of one of the ARRA-funded GSHP demonstration projects, which is a heating only central GSHP system using shallow aquifer as heat source and installed at a warehouse and truck bay at Kalispell, MT. This case study is based on the analysis of measured performance data, utility bills, and calculations of energy consumptions of conventional central heating systems for providing the same heat outputs as the central GSHP system did. The evaluated performance metrics include energy efficiency of the heat pump equipment and the overall GSHP system, pumping performance, energy savings, carbon emission reductions, and cost-effectiveness of GSHP system compared with conventional heating systems. This case study also identified areas for reducing uncertainties in performance evaluation, improving operational efficiency, and reducing installed cost of similar GSHP systems in the future.

Heating and cooling performance analysis of a ground source heat pump system in Southern Germany  

Science Journals Connector (OSTI)

Abstract This paper examines thermal performance of a ground source heat pump (GSHP) system. The GSHP system was installed in an office building in Nuremberg city of Germany. In order to evaluate system performance the GSHP system has been continuously monitored for 4 years. Heating and cooling performance of the GSHP system is analyzed based on the accumulated data. Major findings of this work include: (1) coefficient of performance (COP) is estimated to be 3.9 for a typical winter day and energy efficiency ratio (EER) is assessed to be 8.0 for a typical summer day. These results indicate that the GSHP system has a higher efficiency for building cooling than building heating. (2) For a long-term period, the seasonal energy efficiency ratio (SEER) of the GSHP system is observed to increase by 8.7% annually, whereas the seasonal COP is decreased by 4.0% over a 4-year period. The heating and cooling performance of the GSHP system migrates in opposite trend is caused by the unevenly distributed heating and cooling load of the building. This phenomenon deserves serious attention in the design of future GSHP systems in order to avoid the reducing of energy efficiency over long-term operation.

Chapter 9 - In-Home Deployments  

Science Journals Connector (OSTI)

Abstract In-home deployments can be used to study current behavior patterns or to evaluate prototype systems. Compared to other options such as lab studies, interviews, or surveys, in-home deployments offer unparalleled realism due to the in-situ nature of the deployment as part of the participants normal lives. However, in-home deployments require careful planning and considerable effort. This chapter will help in the planning and successful execution of home deployment studies by sharing insights drawn from our combined experience running many different studies in the home, and by using the deployment of the PreHeat prototype as a concrete example. Among the lessons we highlight are the importance of carefully considering the minimum viable prototype to build for deployment, the value of remote monitoring to catch problems, and the importance of flexibility and robustness in deployed systems to cope with unexpected issues in the home environment. By discussing the challenges we faced and the lessons we learned, we hope that others will be able to more easily conduct in-home deployments and gather the rich and informative data they provide. Our experiences have led us to develop and open source two platforms that strive to reduce the engineering effort required for deployments: .NET Gadgeteer (http://www.netmf.com/gadgeteer/), a prototyping platform for custom devices, and Lab of Things (http://www.lab-of-things.com/), an SDK (software development kit) that provides features such as remote monitoring and updates for home deployments.

Podhale (South Poland) geothermal district heating system  

Science Journals Connector (OSTI)

The search for geothermal resources in the Podhale Region began in the late 1980s. The Banska IG-1 well, drilled in 1981, served as the starting point for an expansion of those research activities. A geothermal pilot plant was put into operation in 1993. During that same year the company Geotermia Podhalanska (GP) was founded and the pilot project, including the first distribution network for 20 customers, was constructed. After the initial phase of project implementation from 1993 to 1995, during which a pilot plant was constructed and put into operation for demonstration purposes by the Polish Academy for Sciences using the first geothermal doublet (a production well in Banska Nizna and a reinjection well in Bialy Dunajec), and connection of 200 households through a small district heating network, the World Bank got involved in the geothermal district heating project. Since then, significant progress has been made, increasing the overall heat capacity and geothermal output as well as the service area to the City of Zakopane, approx. 14 km from the production wells. In November 2001 the first geothermal heat was delivered to customers in Zakopane.

Energy-efficient mortgages and home energy rating systems: A report on the nation`s progress  

SciTech Connect (OSTI)

This report summarizes progress throughout the nation in establishing voluntary programs linking home energy rating systems (HERS) and energy-efficient mortgages (EEMs). These programs use methods for rating the energy efficiency of new and existing homes and predicting energy cost savings so lenders can factor in energy cost savings when underwriting mortgages. The programs also encourage lenders to finance cost-effective energy-efficiency improvements to existing homes with low-interest mortgages or other instruments. The money saved on utility bills over the long term can more than offset the cost of such energy-efficiency improvements. The National Collaborative on HERS and EEMs recommended that this report be prepared.

Heating mechanism affects equipartition in a binary granular system  

E-Print Network [OSTI]

Two species of particles in a binary granular system typically do not have the same mean kinetic energy, in contrast to the equipartition of energy required in equilibrium. We investigate the role of the heating mechanism in determining the extent of this non-equipartition of kinetic energy. In most experiments, different species of particle are unequally heated at the boundaries. We show by event-driven simulations that this differential heating at the boundary influences the level of non-equipartition even in the bulk of the system. This conclusion is fortified by studying a numerical model and a solvable stochastic model without spatial degrees of freedom. In both cases, even in the limit where heating events are rare compared to collisions, the effect of the heating mechanism persists.

Active charge/passive discharge solar heating systems: thermal analysis  

SciTech Connect (OSTI)

The performance of active charge/passive discharge solar space-heating systems is analyzed. This type of system combines liquid-cooled solar collector panels with a massive integral storage component that passively heats the building interior by radiation and free convection. The TRNSYS simulation program is used to evaluate system performance and to provide input for the development of a simplified analysis method. This method, which provides monthly calculations of delivered solar energy, is based on Klein's Phi-bar procedure and data from hourly TRNSYS simulations. The method can be applied to systems using a floor slab, a structural wall, or a water tank as the storage component. Important design parameters include collector area and orientation, building heat loss, collector and heat-exchanger efficiencies, storage capacity, and storage to room coupling.

Analysis of a solar assisted heat pump system for indoor swimming pool water and space heating  

Science Journals Connector (OSTI)

Solar energy application is a good alternative to replace primary energy source especially for large-scale installations. Heat pumps are also effective means to reduce primary energy consumption. This paper describes a case study with a new design of solar assisted heat pump (SAHP) for indoor swimming pool space- and water-heating purposes. The system design procedure was first presented. The entire system was then modeled via the TRNSYS simulation environment and the energy performance was evaluated based on the winter time operation schedule. Economic analysis with a range of collector areas was also performed. The simulation results show that the overall system COP can reach 4.5, and the fractional factor of energy saving is 79% as compared to the conventional energy system. The economical payback period is less than 5years.

This paper introduces four new parameters, namely energetic renewability ratio, exergetic renewability ratio, energetic reinjection ratio, and exergetic reinjection ratio for geothermal district energy systems. These parameters are applied to Edremit Geothermal District Heating System (GDHS) in Balikesir, Turkey for daily, monthly and yearly assessments and their variations are studied. In addition, the actual data are regressed to obtain some applied correlations for practical use. Some results follow: (i) Both energetic and exergetic renewability ratios decrease with decreasing temperature in heating season and increasing temperature in the summer. (ii) Both energetic and exergetic reinjection ratios increase with decreasing temperature for heating season and increase with increasing temperature for summer season.

Solar-assisted heat pump A sustainable system for low-temperature water heating applications  

Science Journals Connector (OSTI)

Abstract Direct expansion solar assisted heat pump systems (DX-SAHP) have been widely used in many applications including water heating. In the DX-SAHP systems the solar collector and the heat pump evaporator are integrated into a single unit in order to transfer the solar energy to the refrigerant. The present work is aimed at studying the use of the DX-SAHP for low temperature water heating applications. The novel aspect of this paper involves a detailed long-term thermo-economic analysis of the energy conservation potential and economic viability of these systems. The thermal performance is simulated using a computer program that incorporates location dependent radiation, collector, economic, heat pump and load data. The economic analysis is performed using the life cycle cost (LCC) method. Results indicate that the DX-SAHP water heaters systems when compared to the conventional electrical water heaters are both economical as well as energy conserving. The analysis also reveals that the minimum value of the system life cycle cost is achieved at optimal values of the solar collector area as well as the compressor displacement capacity. Since the cost of SAHP system presents a barrier to mass scale commercialization, the results of the present study indicating that the SAHP life cycle cost can be minimized by optimizing the collector area would certainly be helpful in lowering, if not eliminating, the economic barrier to these systems. Also, at load temperatures higher than 70C, the performance of the single stage heat pump degrades to the extent that its cost and efficiency advantages over the electric only system are lost.

Pool heating system on island brings year-round enjoyment  

SciTech Connect (OSTI)

The Bahamas is not generally thought of as a place in need of pool heating. However, the remote Bahamian island of Treasure Cay is actually situated north of Ft. Lauderdale, Florida. Pool temperatures drop during the winter, thus shortening the swimming season. The Beach Villas Homeowners Association of Treasure Cay investigated pool-heating options some time ago. Energy on Treasure Cay is expensive - about 25 cents/kWh - making cost a major concern for the association as they evaluated their choices. An electric heat pump was rule out as it would place too great a burden on the electricity load of the remote island. Heating the pool with propane gas was deemed far too costly. After evaluating each of these heating methods on the basis of economics, energy efficiency, and comfort, the association concluded that solar would be the best method. They selected a solar pool heating system manufactured by FAFCO, Inc. and installed by SUNWORKS in Ft. Lauderdale. The system requires virtually no daily maintenance, and there have been no problems with the system since its installation. In addition to being trouble-free, the FAFCO solar pool heater has saved Treasure Cay a great deal of money. The equipment cost about $9,500; lumber, PVC, and labor brought the total cost to $13,000. By comparison, a propane-gas system would have cost $4,000 but would have generated a yearly gas bill of $12,000. Therefore, payback on the system began immediately upon installation.

Building America Case Study: Lancaster County Career and Technology Center Green Home 3, Mt Joy, Pennsylvania  

SciTech Connect (OSTI)

Transitioning from standard light frame to a thermal mass wall system in a high performance home will require a higher level of design integration with the mechanical systems. The much higher mass in the ICF wall influences heat transfer through the wall and affects how the heating and cooling system responds to changing outdoor conditions. This is even more important for efficient, low-load homes with efficient heat pump systems in colder climates where the heating and cooling peak loads are significantly different from standard construction.This report analyzes a range of design features and component performance estimates in an effort to select practical, cost-effective solutions for high performance homes in a cold climate. Of primary interest is the influence of the ICF walls on developing an effective air sealing strategy and selecting an appropriate heating and cooling equipment type and capacity. The domestic water heating system is analyzed for costs and savings to investigate options for higher efficiency electric water heating. A method to ensure mechanical ventilation air flows is examined. The final solution package includes high-R mass walls, very low infiltration rates, multi-stage heat pump heating, solar thermal domestic hot water system, and energy recovery ventilation. This solution package can be used for homes to exceed 2012 International Energy Conservation Code requirements throughout all climate zones and achieves the DOE Challenge Home certification.

LED bulbs technical specification and testing procedure for solar home systems  

Science Journals Connector (OSTI)

Abstract The definition of technical specifications and the corresponding laboratory procedures are necessary steps in order to assure the quality of the devices prior to be installed in Solar Home Systems (SHS). To clarify and unify criteria a European project supported the development of the Universal Technical Standard for Solar Home Systems (UTSfSHS). Its principles were to generate simple and affordable technical requirements to be optimized in order to facilitate the implementation of tests with basic and simple laboratory tools even on the same SHS electrification program countries. These requirements cover the main aspects of this type of installations and its lighting chapter was developed based on the most used technology at that time: fluorescent tubes and CFLs. However, with the consolidation of the new LED solid state lighting devices, particular attention is being given to this matter and new procedures are required. In this work we develop a complete set of technical specifications and test procedures that have been designed within the frame of the UTSfSHS, based on an intense review of the scientific and technical publications related to LED lighting and their practical application. They apply to lamp reliability, performance and safety under normal, extreme and abnormal operating conditions as a simple but complete quality meter tool for any LED bulb. These tests have been applied to a group of 14 low-cost direct current LED bulbs and the accomplishment of the proposed requirements is analyzed.

This article describes a numerical model that can be used to size these foundation heat exchanger (FHX) systems. The numerical model is a two-dimensional finite-volume model that considers a wide variety of factors, such as soil freezing and evapotranspiration. The FHX numerical model is validated with one year of experimental data collected at an experimental house located near Oak Ridge, Tennessee. The model shows good agreement with the experimental data-heat pump entering fluid temperatures typically within 1 C (1.8 F) - with minor discrepancies due to approximations, such as constant moisture content throughout the year, uniform evapotranspiration over the seasons, and lack of ground shading in the model.

A Waste Heat Recovery System for Light Duty Diesel Engines  

SciTech Connect (OSTI)

In order to achieve proposed fuel economy requirements, engines must make better use of the available fuel energy. Regardless of how efficient the engine is, there will still be a significant fraction of the fuel energy that is rejected in the exhaust and coolant streams. One viable technology for recovering this waste heat is an Organic Rankine Cycle. This cycle heats a working fluid using these heat streams and expands the fluid through a turbine to produce shaft power. The present work was the development of such a system applied to a light duty diesel engine. This lab demonstration was designed to maximize the peak brake thermal efficiency of the engine, and the combined system achieved an efficiency of 44.4%. The design of the system is discussed, as are the experimental performance results. The system potential at typical operating conditions was evaluated to determine the practicality of installing such a system in a vehicle.

A demand side management strategy based on forecasting of residential renewable sources: A smart home system in Turkey  

Science Journals Connector (OSTI)

Abstract The existing electricity systems have been substantially designed to allow only centralized power generation and unidirectional power flow. Therefore, the objective of improving the conventional power systems with the capabilities of decentralized generation and advanced control has conflicted with the present power system infrastructure and thus a profound change has necessitated in the current power grids. To that end, the concept of smart grid has been introduced at the last decades in order to accomplish the modernization of the power grid while incorporating various capabilities such as advanced metering, monitoring and self-healing to the systems. Among the various advanced components in smart grid structure, smart home is of vital importance due to its handling difficulties caused by the stochastic behaviors of inhabitants. However, limited studies concerning the implementation of smart homes have so far been reported in the literature. Motivated by this need, this paper investigates an experimental smart home with various renewable energy sources and storage systems in terms of several aspects such as in-home energy management, appliances control and power flow. Furthermore, the study represents one of the very first attempts to evaluate the contribution of power forecasting of renewable energy sources on the performance of smart home concepts.

On flow and supply temperature control in district heating systems  

Science Journals Connector (OSTI)

This paper discusses how the control of the flow and the supply temperature in district heating systems can be optimized, utilizing stochastic modelling, prediction and control methods. The main objective is to reduce heat production costs and heat losses in the transmission and distribution net by minimizing the supply temperature at the district heating plant. This control strategy is reasonable, in particular, if the heat production takes place at a combined heat and power (CHP) plant. The control strategy is subject to some restrictions, e.g. that the total heat requirement for all consumers is supplied at any time, and each individual consumer is guaranteed some minimum supply temperature at any time. Another important restriction is that the variation in time of the supply temperature is kept as small as possible. This concept has been incorporated in the program package, PRESS, developed at the Technical University of Denmark. PRESS has been applied and tested, e.g. at Vestkraft in Esbjerg, Denmark, and significant saving potentials have been documented. PRESS is now distributed by the Danish District Heating Association.

Simulation and analysis of district-heating and -cooling systems  

SciTech Connect (OSTI)

A computer simulation model, GEOCITY, was developed to study the design and economics of district heating and cooling systems. GEOCITY calculates the cost of district heating based on climate, population, energy source, and financing conditions. The principal input variables are minimum temperature, heating degree-days, population size and density, energy supply temperature and distance from load center, and the interest rate. For district cooling, maximum temperature and cooling degree-hours are required. From this input data the model designs the fluid transport and district heating systems. From this design, GEOCITY calculates the capital and operating costs for the entire system. GEOCITY was originally developed to simulate geothermal district heating systems and thus, in addition to the fluid transport and distribution models, it includes a reservoir model to simulate the production of geothermal energy from geothermal reservoirs. The reservoir model can be adapted to simulate the supply of hot water from any other energy source. GEOCITY has been used extensively and has been validated against other design and cost studies. GEOCITY designs the fluid transport and distribution facilities and then calculates the capital and operating costs for the entire system. GEOCITY can simulate nearly any financial and tax structure through varying the rates of return on equity and debt, the debt-equity ratios, and tax rates. Both private and municipal utility systems can be simulated.

A thermal energy transport and storage system is provided which includes an evaporator containing a mixture of a first phase change material and a silica powder, and a condenser containing a second phase change material. The silica powder/PCM mixture absorbs heat energy from a source such as a solar collector such that the phase change material forms a vapor which is transported from the evaporator to the condenser, where the second phase change material melts and stores the heat energy, then releases the energy to an environmental space via a heat exchanger. The vapor is condensed to a liquid which is transported back to the evaporator. The system allows the repeated transfer of thermal energy using the heat of vaporization and condensation of the phase change material.

Assessment of dynamic energy conversion systems for radioisotope heat sources  

SciTech Connect (OSTI)

The use of dynamic conversion systems to convert the heat generated in a 7500 W(t) 90 Sr radioisotopic heat source to electricity is examined. The systems studies were Stirling; Brayton Cycle; three organic Rankines (ORCs) (Barber-Nichols/ORMAT, Sundstrand, and TRW); and an organic Rankine plus thermoelectrics. The systems were ranked for a North Warning System mission using a Los Alamos Multiattribute Decision Theory code. Three different heat source designs were used: case I with a beginning of life (BOL) source temperature of 640 C, case II with a BOL source temperature of 745/sup 0/C, and case III with a BOL source temperature of 945/sup 0/C. The Stirling engine system was the top-ranked system of cases I and II, closely followed by the ORC systems in case I and ORC plus thermoelectrics in case II. The Brayton cycle system was top-ranked for case III, with the Stirling engine system a close second. The use of /sup 238/Pu in heat source sizes of 7500 W(t) was examined and found to be questionable because of cost and material availability and because of additional requirements for analysis of safeguards and critical mass.

An intelligent visual hand motion tracking system for home-based rehabilitation  

Science Journals Connector (OSTI)

Human motion tracking is the key technology for intelligent rehabilitation systems in which the movement of disabled people can be localised and learned and any undesired motion behaviour can be corrected to reach an expectation. This paper introduces a real-time tracking system of human hand motion, specifically used for home based rehabilitation. A hybrid tracking algorithm based on an improved Camshift and a Kalman filter is proposed. In the tracking process, Camshift converts the raw image to a flesh colour probability distribution image via a colour probability table. Considering the hand motion and flesh colour probability distribution, the size and location of a search window are initialised by using the object histogram model. Computed information is used to adjust current search window's size and location, then the location of the hand are found. Experimental results show that this algorithm is fast, accurate, and robust. It can not only deal with the skin colour interference problems, but also handle complex background.

Geothermal district heating system feasibility analysis, Thermopolis, Wyoming  

SciTech Connect (OSTI)

The purpose of this study is to determine the technical and economic feasibility of constructing and operating a district heating system to serve the residential, commercial, and public sectors in Thermopolis. The project geothermal resource assessment, based on reviews of existing information and data, indicated that substantial hot water resources likely exist in the Rose Dome region 10 miles northeast of Thermopolis, and with quantities capable of supporting the proposed geothermal uses. Preliminary engineering designs were developed to serve the space heating and hot water heating demands for buildings in the Thermopolis-East Thermopolis town service area. The heating district design is based on indirect geothermal heat supply and includes production wells, transmission lines, heat exchanger units, and the closed loop distribution and collection system necessary to serve the individual customers. Three options are presented for disposal of the cooled waters-reinjection, river disposal, and agricultural reuse. The preliminary engineering effort indicates the proposed system is technically feasible. The design is sized to serve 1545 residences, 190 businesses, and 24 public buildings. The peak design meets a demand of 128.2 million Btu at production rates of 6400 gpm.

Geothermal heating system for the Children's Museum of Utah  

SciTech Connect (OSTI)

The results of a study to determine the engineering and economic feasibility of using the Wasatch Hot Spring resource for space heating of the Children's Library building are presented. The Wasatch Hot Spring with a reported flow of about 63 gpm (240 l/min) at an average temperature of 104/sup 0/F is not capable of furnishing the needed heat for the Children's Museum building. The underground paths along which the thermal waters flow to their outlets at the Warm Springs Fault are not presently known. It is possible if the thermal water ascends from the deep layers of the earth along the Warm Springs Fault that increased geothermal flow at a higher temperature can be produced by drilling into the fault. Assuming that sufficient geothermal fluid quantity is produced by drilling in the area, an analysis is made of a geothermal heating system for the building based on different fluid temperatures. It is assumed that the present and planned heating systems be left intact with the gas fired boilers taking over during cold periods when the geothermal system fails to provide sufficient heat. Economic analysis shows that the geothermal system is very attractive, even for the lowest geothermal fluid temperature considered (110/sup 0/F).

Composite quantum systems and environment-induced heating  

E-Print Network [OSTI]

In recent years, much attention has been paid to the development of techniques which transfer trapped particles to very low temperatures. Here we focus our attention on a heating mechanism which contributes to the finite temperature limit in laser sideband cooling experiments with trapped ions. It is emphasized that similar heating processes might be present in a variety of composite quantum systems whose components couple individually to different environments. For example, quantum optical heating effects might contribute significantly to the very high temperatures which occur during the collapse phase in sonoluminescence experiments. It might even be possible to design composite quantum systems, like atom-cavity systems, such that they continuously emit photons even in the absence of external driving.

RDI's Wisdom Way Solar Village Final Report: Includes Utility Bill Analysis of Occupied Homes  

SciTech Connect (OSTI)

In 2010, Rural Development, Inc. (RDI) completed construction of Wisdom Way Solar Village (WWSV), a community of ten duplexes (20 homes) in Greenfield, MA. RDI was committed to very low energy use from the beginning of the design process throughout construction. Key features include: 1. Careful site plan so that all homes have solar access (for active and passive); 2. Cellulose insulation providing R-40 walls, R-50 ceiling, and R-40 floors; 3. Triple-pane windows; 4. Airtight construction (~0.1 CFM50/ft2 enclosure area); 5. Solar water heating systems with tankless, gas, auxiliary heaters; 6. PV systems (2.8 or 3.4kWSTC); 7. 2-4 bedrooms, 1,100-1,700 ft2. The design heating loads in the homes were so small that each home is heated with a single, sealed-combustion, natural gas room heater. The cost savings from the simple HVAC systems made possible the tremendous investments in the homes' envelopes. The Consortium for Advanced Residential Buildings (CARB) monitored temperatures and comfort in several homes during the winter of 2009-2010. In the Spring of 2011, CARB obtained utility bill information from 13 occupied homes. Because of efficient lights, appliances, and conscientious home occupants, the energy generated by the solar electric systems exceeded the electric energy used in most homes. Most homes, in fact, had a net credit from the electric utility over the course of a year. On the natural gas side, total gas costs averaged $377 per year (for heating, water heating, cooking, and clothes drying). Total energy costs were even less - $337 per year, including all utility fees. The highest annual energy bill for any home evaluated was $458; the lowest was $171.

Home Energy Checklist Home Energy Checklist This checklist outlines actions that conserve energy within homes. Today Turn down the temperature of your water heater to the warm setting (120°F). You'll save energy and avoid scalding your hands. Check if your water heater has an insulating blanket. An insulating blanket will pay for itself in one year or less! Heating can account for almost half of the average family's winter energy bill. Make sure your furnace or heat pump receives professional maintenance each year. And look for the ENERGY STAR® label when replacing your system. Review additional strategies to reduce your water heating bills. Water heating can account for 14%-25% of the energy consumed in your home. Survey your incandescent lights for opportunities to replace them with compact fluorescent lights (CFLs) or light-emitting diodes (LEDs). CFLs can save three-quarters of the electricity used by incandescents. The best targets are 60-100 W bulbs used several hours a day.

Renewable energy of waste heat recovery system for automobiles  

Science Journals Connector (OSTI)

A system to recover waste heat comprised of eight thermoelectric generators (TEGs) to convert heat from the exhaust pipe of an automobile to electrical energy has been constructed. Simulations and experiments for the thermoelectric module in this system are undertaken to assess the feasibility of these applications. In order to estimate the temperature difference between thermoelectric elements a network of thermal resistors is constructed. The results assist in predicting power output of TEG module more precisely. Three configurations of heat sinks which are comprised of 10 22 and 44 fins are applied in this simulation. The results of the simulations show the average thermal resistance of these heat sinks in each section of the system with varied velocity of external flow. As the performance of a TEG module is influenced by an applied pressure through the effect of the thermal contact resistance we clamp the TE module to our experimental apparatus; the relation between power output and pressure applied in this case is presented. Besides simulations the system is designed and assembled. Measurements followed the connection of the system to the middle of an exhaust pipe. Through these simulations and experiments the power generated with a commercial TEG is presented. The results establish the fundamental development of materials that enhance the TEG efficiency for vehicles.

How does it work? A geothermal heat pump uses the constant below ground temperature of soil or water to heat and cool your home. Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300% to 600%) on the coldest

Marketing the Klamath Falls Geothermal District Heating system  

SciTech Connect (OSTI)

The Klamath Falls Geothermal District Heating system was completed in 1981 and, until 1992, there was no formal marketing plan for the system. This lack of marketing and the system history of poor availability combined to reduce or eliminate interest in connecting on the part of local building owners and it served only the original 14 government buildings connected at start up. The revenue from these buildings, however, did not cover the entire cost of operating the system. As a result, the city was faced with a difficult decision - develop the revenue required to make the system self-supporting or shut it down. As a result, a marketing strategy for the system was developed. A flat rate was developed in which the rate is negotiable, but for most customers approximates 50% of the gas bill. In addition, the flat rate reduced customer retrofit costs because it is not necessary to buy a meter. Finally, the flat rate is a guaranteed value for the first 10 years of the contract. To reduce retrofit costs, the new marketing plan eliminates the requirement for a customer heat exchanger. New customers are now connected directly into the distribution system with district loop water used as the building heating medium. The state operates two programs which have been used in the marketing plan. The first of these is available only to taxable entities and is referred to as the Business Energy Tax Credit (BETC). This program offers business a 35% tax credit on the costs associated with connection to the geothermal district heat system (retrofit, design, permits, etc.). The second state program is the Small Energy Loan Program (SELP). This program will loan the entire cost of the energy project to the customer. The new marketing strategy for the Klamath Falls system has concentrated on offering the customer an attractive and easy to understand rate structure, reduced retrofit cost and complexity for this building along with an attractive package of financing and tax credits. 1 tab.

An assessment of unforeseen losses resulting from inappropriate use of solar home systems in South Africa  

Science Journals Connector (OSTI)

Abstract One of the challenges to the sustainability of the Solar Home System (SHS) electrification program in South Africa is equipment theft. In response to this, communities susceptible to solar panel theft resort to mounting their panels flat on the ground so they can be looked after during the day and taken indoors at night for safe keeping. Other households use their security lights to illuminate their environment and provide security for pole and roof mounted solar panels at night. These actions have consequential effects on the performance of the SHS. Several studies have detected resentment from households regarding the low power quality from these systems. Most scientific contributions on the issue of low power from SHS have focused on the challenges based on the technical designs of the systems. The power losses due to the usage pattern of the system has not received much attention. This study therefore reports on the technical losses as a result of the deviation from the designed and installed specification of the system by the users in order to protect their systems. It also investigates the linkage between the technical and economic losses which affects the sustainability of SHS program. A case study was performed in Thlatlaganya village within Limpopo province in South Africa. Technical analysis using PVSYST solar software revealed that the energy output and performance of the battery is compromised as a result of these practices. Economic analysis indicates that the battery life and the economics of owning and operating SHS are affected negatively. The study recommends solutions to mitigate these losses, and proposes a cost effective way of optimizing the operation of SHS using a Bench-Rack system for mounting solar panels.

Thermodynamic analysis of a geothermal district heating system  

Science Journals Connector (OSTI)

Thermoeconomic analysis is considered a useful tool for investigators in engineering and other disciplines due to its methodology based on the quantities exergy, cost, energy and mass. This study deals with an investigation of capital costs and thermodynamic losses for devices in the Balcova Geothermal District Heating Systems (BGDHS). Thermodynamic loss rate-to-capital cost ratios are used for components and the overall system, and a systematic correlation is found between capital cost and exergy loss (total or internal), but not between capital cost and energy loss or external exergy loss. This correlation may imply that devices in successful district heating system are configured so as to achieve an overall optimal design, by balancing the thermodynamic (exergy-based) and economic characteristics of the overall system and their devices. The results provide insights into the relations between thermodynamics and economics and help demonstrate the merits of exergy analysis.

Solar passive ceiling system. Final report. [Passive solar heating system with venetian blind reflectors and latent heat storage in ceiling  

SciTech Connect (OSTI)

The construction of a 1200 square foot building, with full basement, built to be used as a branch library in a rural area is described. The primary heating source is a passive solar system consisting of a south facing window system. The system consists of: a set of windows located in the south facing wall only, composed of double glazed units; a set of reflectors mounted in each window which reflects sunlight up to the ceiling (the reflectors are similar to venetian blinds); a storage area in the ceiling which absorbs the heat from the reflected sunlight and stores it in foil salt pouches laid in the ceiling; and an automated curtain which automatically covers and uncovers the south facing window system. The system is totally passive and uses no blowers, pumps or other active types of heat distribution equipment. The building contains a basement which is normally not heated, and the north facing wall is bermed four feet high around the north side.

Exergoeconomic analysis of geothermal district heating systems: A case study  

Science Journals Connector (OSTI)

An exergoeconomic study of geothermal district heating systems through mass, energy, exergy and cost accounting analyses is reported and a case study is presented for the Salihli geothermal district heating system (SGDHS) in Turkey to illustrate the present method. The relations between capital costs and thermodynamic losses for the system components are also investigated. Thermodynamic loss rate-to-capital cost ratios are used to show that, for the devices and the overall system, a systematic correlation appears to exist between capital cost and exergy loss (total or internal), but not between capital cost and energy loss or external exergy loss. Furthermore, a parametric study is conducted to determine how the ratio of thermodynamic loss rate to capital cost changes with reference temperature and to develop a correlation that can be used for practical analyses. The correlations may imply that devices in successful district heating systems such as the SGDHS are configured so as to achieve an overall optimal design, by appropriately balancing the thermodynamic (exergy-based) and economic (cost) characteristics of the overall systems and their devices.

A key review of wastewater source heat pump (WWSHP) systems  

Science Journals Connector (OSTI)

Abstract Heat pumps (HPs) are part of the environmentally friendly technologies using renewable energy and have been utilized in the developed countries for years. Wastewater is seen as a renewable heat source for HPs. At the beginning of the 1980s, waste (sewage) water source heat pumps (WWSHPs) were widely applied in North European countries like Sweden and Norway and partially applied in China. In the past two decades, the WWSHP has become increasingly popular due to its advantages of relatively higher energy utilization efficiency and environmental protection. The present study comprehensively reviews WWSHP systems in terms of applications and performance assessments including energetic, exergetic, environmental and economic aspects for the first time to the best of the authors knowledge. In this context, a historical development of \\{WWSHPs\\} was briefly given first. Next, wastewater potential and its characteristics were presented while a WWSHP system was introduced. The previously conducted studies on \\{WWSHPs\\} were then reviewed and classified in a tabulated form. Finally, some concluding remarks were listed. The COP values of the reviewed studies ranged from 1.77 to 10.63 for heating and 2.23 to 5.35 for cooling based on the experimental and simulated values. The performance assessments are mostly made using energy analysis methods while the number of exergetic evaluations is very low and has not been comprehensively performed. It is expected that the comprehensive review here will be very beneficial to those dealing with the design, analysis, simulation and performance assessment of WWSHP systems.
