Hybrid Geothermal Heat Pump Systems  

Science Conference Proceedings (OSTI)

Hybrid geothermal heat pump systems offer many of the benefits of full geothermal systems but at lower installed costs. A hybrid geothermal system combines elements of a conventional water loop heat pump system in order to reduce the geothermal loop heat exchanger costs, which are probably the largest cost element of a geothermal system. These hybrid systems have been used successfully where sufficient ground space to install large heat exchangers for full geothermal options was unavailable, or where the...

heat pump-like an air conditioner or refrigera- heat pump-like an air conditioner or refrigera- tor-moves heat from one place to another. In the summer, a geothermal heat pump (GHP) operating in a cooling mode lowers indoor temperatures by transferring heat from inside a building to the ground outside or below it. Unlike an air condition- er, though, a heat pump's process can be reversed. In the winter, a GHP extracts heat from the ground and transfers it inside. Also, the GHP can use waste heat from summer air-conditioning to provide virtually free hot-water heating. The energy value of the heat moved is typically more than three times the electricity used in the transfer process. GHPs are efficient and require no backup heat because the earth stays at a relatively moderate temperature throughout the year.

Geothermal Heat Pump Benchmarking Report  

SciTech Connect

A benchmarking study was conducted on behalf of the Department of Energy to determine the critical factors in successful utility geothermal heat pump programs. A Successful program is one that has achieved significant market penetration. Successfully marketing geothermal heat pumps has presented some major challenges to the utility industry. However, select utilities have developed programs that generate significant GHP sales. This benchmarking study concludes that there are three factors critical to the success of utility GHP marking programs: (1) Top management marketing commitment; (2) An understanding of the fundamentals of marketing and business development; and (3) An aggressive competitive posture. To generate significant GHP sales, competitive market forces must by used. However, because utilities have functioned only in a regulated arena, these companies and their leaders are unschooled in competitive business practices. Therefore, a lack of experience coupled with an intrinsically non-competitive culture yields an industry environment that impedes the generation of significant GHP sales in many, but not all, utilities.

Heat Pump Basics Heat Pump Basics Geothermal Heat Pump Basics August 19, 2013 - 11:12am Addthis Text Version Geothermal heat pumps use the constant temperature of the earth as an exchange medium for heat. Although many parts of the country experience seasonal temperature extremes-from scorching heat in the summer to sub-zero cold in the winter-the ground a few feet below the earth's surface remains at a relatively constant temperature. Depending on the latitude, ground temperatures range from 45┬░F (7┬░C) to 75┬░F (21┬░C). So, like a cave's, the ground's temperature is warmer than the air above it during winter and cooler than the air above it in summer. Geothermal heat pumps take advantage of this by exchanging heat with the earth through a ground heat exchanger. Geothermal heat pumps are able to heat, cool, and, if so equipped, supply

Heat Pump Basics Heat Pump Basics Photo of the West Philadelphia Enterprise Center. The West Philadelphia Enterprise Center uses a geothermal heat pump system for more than 31,000 square feet of space. Geothermal heat pumps take advantage of the nearly constant temperature of the Earth to heat and cool buildings. The shallow ground, or the upper 10 feet of the Earth, maintains a temperature between 50┬░ and 60┬░F (10┬░-16┬░C). This temperature is warmer than the air above it in the winter and cooler in the summer. Geothermal heat pump systems consist of three parts: the ground heat exchanger, the heat pump unit, and the air delivery system (ductwork). The heat exchanger is a system of pipes called a loop, which is buried in the shallow ground near the building. A fluid (usually water or a mixture of

The thermal conductivity of cementitious grouts has been investigated in order to determine suitability of these materials for grouting vertical boreholes used with geothermal heat pumps. The roles of mix variables such as water/cement ratio, sand/cement ratio and superplasticizer dosage were measured. The cement-sand grouts were also tested for rheological characteristics, bleeding, permeability, bond to HDPE pipe, shrinkage, coefficient of thermal expansion, exotherm, durability and environmental impact. This paper summarizes the thermal conductivity, permeability, bonding and exotherm data for selected cementitious grouts. The theoretical reduction in bore length that could be achieved with the BNL-developed cement-sand grouts is examined. Finally, the FY 98 research and field trials are discussed.

Thermally conductive cementitious grout for geothermal heat pump systems  

DOE Patents (OSTI)

A thermally conductive cement-sand grout for use with a geothermal heat pump system. The cement sand grout contains cement, silica sand, a superplasticizer, water and optionally bentonite. The present invention also includes a method of filling boreholes used for geothermal heat pump systems with the thermally conductive cement-sand grout. The cement-sand grout has improved thermal conductivity over neat cement and bentonite grouts, which allows shallower bore holes to be used to provide an equivalent heat transfer capacity. In addition, the cement-sand grouts of the present invention also provide improved bond strengths and decreased permeabilities. The cement-sand grouts can also contain blast furnace slag, fly ash, a thermoplastic air entraining agent, latex, a shrinkage reducing admixture, calcium oxide and combinations thereof.

GROUND WATER PROTECTION ISSUES WITH GEOTHERMAL HEAT PUMPS  

DOE Green Energy (OSTI)

Closed loop vertical boreholes used with geothermal heat pumps are grouted to facilitate heat transfer and prevent ground water contamination. The grout must exhibit suitable thermal conductivity as well as adequate hydraulic sealing characteristics. Permeability and infiltration tests were performed to assess the ability of cementitious grout to control vertical seepage in boreholes. It was determined that a superplasticized cement-sand grout is a more effective borehole sealant than neat cement over a range of likely operational temperatures. The feasibility of using non-destructive methods to verify bonding in heat exchangers is reviewed.

Increasing Confidence In Geothermal Heat Pump Design Methods  

SciTech Connect

Sizing the ground heat exchanger is one of the most important tasks in the design of a geothermal heat pump (GHP) system. Undersizing the heat exchanger can result in poor operating efficiency, reduced comfort, and nuisance heat pump lockouts on safety controls, while an oversized heat exchanger increases the installation cost of the system. The cost of ground loop installation may mean the difference between a feasible and an unfeasible project. Thus there are strong incentives to select heat exchanger lengths which allow satisfactory performance under all operating conditions within a feasible project budget. Sizing a ground heat exchanger is not a simple calculation. In the first place, there is usually some uncertainty in the peak block and annual space conditioning loads for the building to be served by the GHPs. The thermal properties of the soil formation may be unknown as well. Drilling logs and core samples can identify the soil type, but handbook values for the thermal properties of soils vary widely. Properly-done short-term on-site tests and data analysis to obtain thermal properties provide more accurate information, but since these tests are expensive they are usually only feasible in large projects. Given the uncertainties inherent in the process, if designers were truly working 'close to the edge' - selecting the absolute minimum heat exchanger length required to meet the predicted loads - one would expect to see more examples of undersized heat exchangers. Indeed there have been a few. However, over the past twenty years GHPs have been installed and successfully operated at thousands of locations all over the world. Conversations with customers and facility managers reveal a high degree of satisfaction with the technology, but studies of projects reveal far more cases of generously sized ground heat exchangers than undersized ones. This indicates that the uncertainties in space conditioning loads and soil properties are covered by a factor of safety. These conservative designs increase the installed cost of GHP systems, limiting their use and applicability. Moreover, as ground heat exchanger sizing methods have improved, they have suggested (and field tests are beginning to verify) that standard bore backfill practices lead to unnecessarily large ground heat exchangers. Growing evidence suggests that in many applications use of sand backfill with a grout plug at the surface, or use of bottom-to-top thermally enhanced grout, may provide groundwater protection equal to current practice at far less cost. Site tests of thermal properties provides more accurate information, but since these tests are expensive they are usually only performed in large projects. Even so, because soil properties can vary over a distance as small as a few feet, the value of these tests is limited. One objective of ongoing research at the Oak Ridge National Laboratory (ORNL) is to increase designers confidence in available ground heat exchanger sizing methods that lead to reliable yet cost-effective designs. To this end we have developed research-grade models that address the interactions between buildings, geothermal heat pump systems and ground heat exchangers The first application of these models was at Fort Polk, Louisiana, where the space conditioning systems of over 4,000 homes were replaced with geothermal heat pumps (Shonder and Hughes, 1997; Hughes et. al., 1997). At Fort Polk, the models were calibrated to detailed data from one of the residences. Data on the energy use of the heat pump, combined with inlet and outlet water temperature and flow rate in the ground heat exchangers, allowed us to determine the thermal properties of the soil formation being experienced by the operating GHP system. Outputs from the models provide all the data required by the various commercially-available ground loop sizing programs. Accurate knowledge of both the building loads and the soil properties eliminated the uncertainty normally associated with the design process, and allowed us to compare the predictions of the commercially-available

Systems Study Of Drilling For Installation Of Geothermal Heat Pumps

Geothermal, or ground-source, heat pumps (GHP) are much more efficient than air-source units such as conventional air conditioners. A major obstacle to their use is the relatively high initial cost of installing the heat-exchange loops into the ground. In an effort to identify drivers which influence installation cost, a number of site visits were made during 1996 to assess the state-of-the-art in drilling for GHP loop installation. As an aid to quantifying the effect of various drilling-process improvements, we constructed a spread-sheet based on estimated time and material costs for all the activities required in a typical loop-field installation. By substituting different (improved) values into specific activity costs, the effect on total project costs can be easily seen.

Geothermal heat pumps at Fort Polk: Early results  

DOE Green Energy (OSTI)

At Fort Polk, LA an entire city (4,003 military family housing units) is being converted to geothermal heat pumps (GHP) under a performance contract. At the same time other efficiency measures such as compact fluorescent lights (CFLs), low-flow water outlets, and attic insulation are being installed. If these contracts and this technology are to be used widely in US Department of Defense (DoD) facilities and other public buildings, better data from actual projects is the key. Being the first GHP project of this type and size, Fort Polk proved to be very challenging for all concerned. To get from RFP to start of construction took several years. This hard work by others created a once-in-a-lifetime opportunity to address many of the due diligence issues that delayed the Fort Polk project. So that future projects can move faster, an evaluation has been undertaken to address the following barriers: absence of a documented large-scale demonstration of GHP energy, demand, and maintenance savings (a barrier to acceptance by federal customers, performance contractors, and investors); newness of large-scale facility capital renewal procurements at federal facilities under energy savings performance contracts (ESPCs) or traditional appropriations (lack of case studies); and variability in current GHP design tools (increases risks and costs for federal customers, performance contractors, investors and designers). This paper presents early energy and demand savings results based on data collection through January 1996.

Generic Guide Specification for Geothermal Heat Pump Systems  

SciTech Connect

The attached Geothermal (Ground-Source) Heat Pump (GHP) Guide Specifications have been developed by Oak Ridge National Laboratory (ORNL) with the intent to assist federal agency sites and engineers in the preparation of construction specifications for GHP projects. These specifications have been developed in the industry-standard Construction Specification Institute (CSI) format and cover several of the most popular members of the family of GHP systems. These guide specifications are applicable to projects whether the financing is with conventional appropriations, arranged by GHP specialty ESCOs under the U.S. Department of Energy's Technology-Specific GHP Super ESPCs, arranged by utilities under Utility Energy Service Contracts (UESCs) or arranged by generalist ESCOs under the various regional ESPCs. These specifications can provide several benefits to the end user that will help ensure successful GHP system installations. GHP guide specifications will help to streamline the specification development, review, and approval process because the architecture and engineering (AE) firm will be working from the familiar CSI format instead of developing the specifications from other sources. The guide specifications help to provide uniformity, standardization, and consistency in both the construction specifications and system installations across multiple federal sites. This standardization can provide future benefits to the federal sites in respect to both maintenance and operations. GHP guide specifications can help to ensure that the agency is getting its money's worth from the GHP system by preventing the use of marginal or inferior components and equipment. The agency and its AE do not have to start from scratch when developing specifications and can use the specification as a template and/or a checklist in developing both the design and the contract documents. The guide specifications can save project costs by reducing the engineering effort required during the design development phase. Use of this guide specification for any project is strictly optional and at the discretion of the responsible party in charge. If used as a construction specification master template for GHP systems, this guide specification must, in all cases, be edited to apply to the specific project in question and to reflect the site-specific conditions relevant to the project. There is no guarantee of accuracy or applicability with respect to any portion of this specification and the user assumes all risk associated with the application of the information contained in this document.

Due to its user-friendly interface and comprehensive capacity for performing building load calculations and HVAC system simulations, eQUEST has been widely used in whole building performance analysis for various purposes, including LEED certification and optimization of building envelop and/or HVAC system designs. In 2006, as a cooperative effort between CM and JJH (the developer of eQUEST), eQUEST capabilities were expanded to include simulation of conventional GHP systems comprised of water-to-air heat pump units, horizontal or vertical ground loop heat exchangers (GLHE), and lakes or wells. However, to date, eQUEST does not model hybrid systems, such as the combination of a fluid cooler in series with a GLHE. Nor is it capable of simulating water-to-water heat pumps coupled to a horizontal or vertical GLHE. As a result, significant opportunities are being missed, as hybrid and/or water-to-water GHP system applications may prove to be a cost effective solution in many situations.

Preliminary studies were preformed to determine whether thermal conductivity of cementitious grouts used to backfill heat exchanger loops for geothermal heat pumps could be improved, thus improving efficiency. Grouts containing selected additives were compares with conventional bentonite and cement grouts. Significant enhancement of grout alumina grit, steel fibers, and silicon carbide increased the thermal conductivity when compared to unfilled, high solids bentonite grouts and conventional cement grouts. Furthermore, the developed grouts retained high thermal conductivity in the dry state, where as conventional bentonite and cement grouts tend to act as insulators if moisture is lost. The cementitious grouts studied can be mixed and placed using conventional grouting equipment.

Improving Water Loop Heat Pump Performance by Using Low Temperature Geothermal Fluid  

DOE Green Energy (OSTI)

Water-loop heat pump (WLHP) systems are an important option for space conditioning of commercial buildings. They provide the opportunity of saving energy through heat recovery and thermal balancing when heating and cooling occur simultaneously. WLHP systems typically operate with loop water temperature between 16 C and 32 C. When cooling loads dominate, loop water temperatures are maintained below 32 C by rejecting excess heat with a cooling tower. When heating dominates, loop water temperatures are maintained above 16 C by a heater input. The capacity and efficiency of water-source heat pumps (WSHP) in both operating modes are strong functions of the inlet water temperature. The emphasis of this paper is on the analysis of system performances, energy savings of the mixed cooling and heating mode of the WLHP systems for it is a unique operating mode in the air-conditioning and space heating systems. The energy saving effect by using low temperature geothermal as the heat input for WLHP systems was examined.

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

SciTech Connect

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.

Optimal power consumption in a central heating system with geothermal heat pump  

E-Print Network (OSTI)

Abstract: A ground source heat pump connected to a domestic hydronic heating network is studied to be driven with the minimum electric power. The hypothesis is to decrease the forward temperature to the extent that one of the hydronic heaters work at full capacity. A less forward temperature would result in a dramatic temperature drop in the room with saturated actuator. The optimization hypothesis is inspired by the fact that, the consumed electric power by the heat pump has a strong positive correlation with the generated forward temperature. A model predictive control scheme is proposed in the current study to achieve the optimal forward temperature. At the lower hierarchy level, local PI controllers seek the corresponding room temperature setpoint. Simulation results for a multi-room house case study show considerable energy savings compared to the heat pumpĺs traditional control scheme.

Thermal conductivity of cementitious grouts for geothermal heat pumps. Progress report FY 1997  

DOE Green Energy (OSTI)

Grout is used to seal the annulus between the borehole and heat exchanger loops in vertical geothermal (ground coupled, ground source, GeoExchange) heat pump systems. The grout provides a heat transfer medium between the heat exchanger and surrounding formation, controls groundwater movement and prevents contamination of water supply. Enhanced heat pump coefficient of performance (COP) and reduced up-front loop installation costs can be achieved through optimization of the grout thermal conductivity. The objective of the work reported was to characterize thermal conductivity and other pertinent properties of conventional and filled cementitious grouts. Cost analysis and calculations of the reduction in heat exchanger length that could be achieved with such grouts were performed by the University of Alabama. Two strategies to enhance the thermal conductivity of cementitious grouts were used simultaneously. The first of these was to incorporate high thermal conductivity filler in the grout formulations. Based on previous tests (Allan and Kavanaugh, in preparation), silica sand was selected as a suitable filler. The second strategy was to reduce the water content of the grout mix. By lowering the water/cement ratio, the porosity of the hardened grout is decreased. This results in higher thermal conductivity. Lowering the water/cement ratio also improves such properties as permeability, strength, and durability. The addition of a liquid superplasticizer (high range water reducer) to the grout mixes enabled reduction of water/cement ratio while retaining pumpability. Superplasticizers are commonly used in the concrete and grouting industry to improve rheological properties.

Geothermal (Ground-Source) Heat Pumps: Market Status, Barriers to Adoption, and Actions to Overcome Barriers  

Science Conference Proceedings (OSTI)

More effective stewardship of our resources contributes to the security, environmental sustainability, and economic well-being of the nation. Buildings present one of the best opportunities to economically reduce energy consumption and limit greenhouse gas emissions. Geothermal heat pump systems (GHPs), sometimes called ground-source heat pump or Geo-Exchange systems, have been proven capable of producing large reductions in energy use and peak demand in buildings. However, GHPs have received little attention at the policy level as an important component of a national energy and climate strategy. Have policymakers mistakenly overlooked GHPs, or are GHPs simply unable to make a major contribution to the national goals for various reasons? This brief study was undertaken at DOE s request to address this conundrum. The scope of the study includes determining the status of global GHP markets and the status of the GHP industry and technology in the United States, assembling previous estimates of GHP energy savings potential and other benefits, identifying key barriers to application of GHPs, and identifying actions that could accelerate market adoption of GHPs. The findings are documented in a report along with conclusions and recommendations. This paper summarizes the key information from the report.

The Earth-Coupled or Geothermal Heat Pump Air Conditioning System  

E-Print Network (OSTI)

As utility costs have risen despite political campaign promises and energy conserving measures implemented by the utility companies such as alternative fuel use (coal and nuclear), co-generation, etc., homeowners have begun to search for effective methods of reducing their electricity bills. In some cases homeowners are faced with utility bills That are approaching the cost of their mortgage payments. For those with fixed incomes, such as the elderly or those looking forward to retirement in the near future, this has become an alarming reality. Virtually every homeowner would like to reduce his utility bill but the question is, what items should he address in order to have a significant impact on his electricity costs? According to Houston Lighting h Power Company, 50% of an electricity bill can be attributed to the air conditioning system, and another 15-20% to the hot water heating system. Therefore, to dramatically reduce utility costs one should look first at these two "energy gulpers" and next at proper home insulation, window coverings, etc. The other electrical appliances in the home use relatively minor amounts of electricity compared to the air conditioning and hot water heating system. This paper will describe the geothermal heat pump and the desuperheater as the latest developments in energy efficient air conditioning and water heating.

Thermally conductive cementitious grouts for geothermal heat pumps. Progress report FY 1998  

DOE Green Energy (OSTI)

Research commenced in FY 97 to determine the suitability of superplasticized cement-sand grouts for backfilling vertical boreholes used with geothermal heat pump (GHP) systems. The overall objectives were to develop, evaluate and demonstrate cementitious grouts that could reduce the required bore length and improve the performance of GHPs. This report summarizes the accomplishments in FY 98. The developed thermally conductive grout consists of cement, water, a particular grade of silica sand, superplasticizer and a small amount of bentonite. While the primary function of the grout is to facilitate heat transfer between the U-loop and surrounding formation, it is also essential that the grout act as an effective borehole sealant. Two types of permeability (hydraulic conductivity) tests was conducted to evaluate the sealing performance of the cement-sand grout. Additional properties of the proposed grout that were investigated include bleeding, shrinkage, bond strength, freeze-thaw durability, compressive, flexural and tensile strengths, elastic modulus, Poisson`s ratio and ultrasonic pulse velocity.

Monitored performance of residential geothermal heat pumps in central Texas and Southern Michigan  

DOE Green Energy (OSTI)

This report summarizes measured performance of residential geothermal heat pumps (GHP`s) that were installed in family housing units at Ft. Hood, Texas and at Selfridge Air National Guard base in Michigan. These units were built as part of a joint Department of Defense/Department of Energy program to evaluate the energy savings potential of GHP`s installed at military facilities. At the Ft. Hood site, the GHP performance was compared to conventional forced air electric air conditioning and natural gas heating. At Selfridge, the homes under test were originally equipped with electric baseboard heat and no air conditioning. Installation of the GHP systems at both sites was straightforward but more problems and costs were incurred at Selfridge because of the need to install ductwork in the homes. The GHP`s at both sites produced impressive energy savings. These savings approached 40% for most of the homes tested. The low cost of energy on these bases relative to the incremental cost of the GHP conversions precludes rapid payback of the GHP`s from energy savings alone. Estimates based on simple payback (no inflation and no interest on capital) indicated payback times from 15 to 20 years at both sites. These payback times may be reduced by considering the additional savings possible due to reduced maintenance costs. Results are summarized in terms of 15 minute, hourly, monthly, and annual performance parameters. The results indicate that all the systems were working properly but several design shortcomings were identified. Recommendations are made for improvements in future installations at both sites.

Geothermal heat pump energy savings performance contract at Fort Polk, LA: Lessons learned  

DOE Green Energy (OSTI)

At Fort Polk, LA the space conditioning systems of 4,003 military family housing units have been converted to geothermal heat pumps (GHP) under an energy savings performance contract (ESPC). At the same time, other efficiency measures, such as compact fluorescent lights (CFLs), low-flow shower heads, and attic insulation, were installed. An independent evaluation of the Fort Polk ESPC was carried out. Findings indicate that the project has resulted in a 25.6 million kWh savings in electrical energy use, or 32.4% of the pre-retrofit electrical consumption in family housing, for a typical meteorological year. Peak electrical demand has also been reduced by 6,541 kW, which is 39.6% of the pre-retrofit peak demand. Natural gas savings are about 260,000 therms per year. In addition, the ESPC has allowed the Army to effectively cap its future expenditures for family housing HVAC maintenance at about 77% of its previous costs. Given these successful results, the Fort Polk ESPC can provide a model for other ESPCs in both the public and the private sectors. The purpose of this paper is to outline the method by which the ESPC was engineered and implemented, both from the standpoint of the facility owner (the US Army) and the energy services company (ESCO) which is carrying out the contract. The lessons learned from this experience should be useful to other owners, ESCOs and investors in the implementation of future ESPCs. It should be noted that the energy savings presented in this document are the apparent energy savings observed in the monitored data, and are not to be confused with the contracted energy savings used as the basis for payments. To determine the contracted energy savings, the apparent energy savings may require adjustments for such things as changes in indoor temperature performance criteria, additions of ceiling fans, and other factors.

Geothermal Heat Pumps in K-12 Schools -- A Case Study of the Lincoln, Nebraska, Schools  

DOE Green Energy (OSTI)

Geothermal heat pumps (GHPs) have been shown to have a number of benefits over other technologies used to heat and cool buildings and provide hot water, combining high levels of occupant comfort with low operating and maintenance costs. Public facilities represent an increasingly important market for GHPs, and schools are a particularly good application, given the large land area that normally surrounds them. Nevertheless, some barriers remain to the increased use of GHPs in institutional and commercial applications. First, because GHPs are perceived as having higher installation costs than other space conditioning technologies, they are sometimes not considered as an option in feasibility studies. When they are considered, it can be difficult to compile the information required to compare them with other technologies. For example, a life cycle cost analysis requires estimates of installation costs and annually recurring energy and maintenance costs. But most cost estimators are unfamiliar with GHP technology, and no published GHP construction cost estimating guide is available. For this reason, estimates of installed costs tend to be very conservative, furthering the perception that GHPs are more costly than other technologies. Because GHP systems are not widely represented in the various softwares used by engineers to predict building energy use, it is also difficult to estimate the annual energy use of a building having GHP systems. Very little published data is available on expected maintenance costs either. Because of this lack of information, developing an accurate estimate of the life cycle cost of a GHP system requires experience and expertise that are not available in all institutions or in all areas of the country. In 1998, Oak Ridge National Laboratory (ORNL) entered into an agreement with the Lincoln, Nebraska, Public School District and Lincoln Electric Service, the local electric utility in the Lincoln area, to study four new, identical elementary schools built in the district that are served by GHPs. ORNL was provided with complete as-built construction plans for the schools and associated equipment, access to original design calculations and cost estimates, extensive equipment operating data [both from the buildings' energy management systems (EMSs) and from utility meters], and access to the school district's complete maintenance record database, not only for the four GHP schools, but for the other schools in the district using conventional space conditioning equipment. Using this information, we were able to reproduce the process used by the Lincoln school district and the consulting engineering firm to select GHPs over other options to provide space conditioning for the four schools. The objective was to determine whether this decision was the correct one, or whether some other technology would have been more cost-effective. An additional objective was to identify all of the factors that make it difficult for building owners and their engineers to consider GHPs in their projects so that ongoing programs can remove these impediments over time.

Monitored energy use of homes with geothermal heat pumps: A compilation and analysis of performance. Final report  

SciTech Connect

The performance of residential geothermal heat pumps (GHPs) was assessed by comparing heating, ventilation, and air conditioning (HVAC) system and whole house energy use of GHP houses and control houses. Actual energy savings were calculated and compared to expected savings (based on ARI ratings and literature) and predicted savings (based on coefficient of performance - COP - measurements). Differences between GHP and control houses were normalized for heating degree days and floor area or total insulation value. Predicted savings were consistently slightly below expected savings but within the range of performance cited by the industry. Average rated COP was 3.4. Average measured COP was 3.1. Actual savings were inconsistent and sometimes significantly below predicted savings. No correlation was found between actual savings and actual energy use. This suggests that factors such as insulation and occupant behavior probably have greater impact on energy use than type of HVAC equipment. There was also no clear correlation between climate and actual savings or between climate and actual energy use. There was a trend between GHP installation date and savings. Newer units appear to have lower savings than some of the older units which is opposite of what one would expect given the increase in rated efficiencies of GHPs. There are a number of explanations for why actual savings are repeatedly below rated savings or predicted savings. Poor ground loop sizing or installation procedures could be an issue. Given that performance is good compared to ASHPs but poor compared to electric resistance homes, the shortfall in savings could be due to duct leakage. The takeback effect could also be a reason for lower than expected savings. Occupants of heat pump homes are likely to heat more rooms and to use more air-conditioning than occupants of electric resistance homes. 10 refs., 17 figs., 10 tabs.

The design configuration and fabrication description of a transportable geothermal pump test facility are discussed. The test facility, consisting of a test rig and data acquisition system trailer, provides the user with the unique opportunity to develop and calibrate geothermal pumps with less liability and risk, and at lower cost than would be incurred by actually installing the pump in a geothermal well. Pump tests may be performed using either domestic water, heated by pumping energy, or by using actual geothermal brines supplied directly to the test rig which would be located adjacent to the well. The geothermal pump test facility is completely self supporting and requires only an electrical supply source to become fully operational. Information and discussion presented provide substantive background, design and operational capabilities, and pertinent fabrication details.

Irrigation pumping using geothermal energy  

DOE Green Energy (OSTI)

The potential of using geothermal energy in an isobutane binary system to drive directly a cluster of irrigation pumps was evaluated. This three well geothermal system, based at 150{sup 0}C (302{sup 0}F) resource at 2000 m (6560 ft), would cost an estimated $7,800,000 in capital investment to provide 6000 gpm of irrigation water from 12 water wells. It would serve approximately 4.5 square miles of irrigated agricultural land, with the delivered water costing $106.76 per acre-foot. This compares with an estimated cost of $60.78 per acre-foot for a conventional irrigation system driven by natural gas at the current price (1980 dollars) of $2.72/mm Btu. It is obvious that if natural gas prices continue to rise, or if geothermal resources can be found at depths less than 2000 meters, then the geothermal irrigation pumping system would be attractive economically. The importance of water to the economy and growth of Arizona was summarized. Total water consumption in Arizona is about 7,600,000 acre-feet annually of which about 87% is used for agriculture. Total supply from the Colorado River and water runoff is only 2,600,000 acre-feet per year, resulting in a net potable groundwater depletion of about 4,000,000 acre-feet per year assuming a recharge rate of about 1,000,000 acre-feet per year.

Geothermal Energy: Residential Space Heating  

DOE Green Energy (OSTI)

The purpose of this study, which was carried out under the auspices of the DGRST, was to determine the best way to use geothermal hot water for residential space heating. It quickly became apparent that the type of heating apparatus used in the housing units was most important and that heat pumps could be a valuable asset, making it possible to extract even more geothermal heat and thus substantially improve the cost benefit of the systems. Many factors play a significant role in this problem. Therefore, after a first stage devoted to analyzing the problem through a manual method which proved quite useful, the systematic consideration of all important aspects led us to use a computer to optimize solutions and process a large number of cases. The software used for this general study can also be used to work out particular cases: it is now available to any interested party through DGRST. This program makes it possible to: (1) take climatic conditions into account in a very detailed manner, including temperatures as well as insolation. 864 cases corresponding to 36 typical days divided into 24 hours each were chosen to represent the heating season. They make it possible to define the heating needs of any type of housing unit. (2) simulate and analyze the behavior in practice of a geothermal heating system when heat is extracted from the well by a simple heat exchanger. This simulation makes it possible to evaluate the respective qualities of various types of heating apparatus which can be used in homes. It also makes it possible to define the best control systems for the central system and substations and to assess quite accurately the presence of terminal controls, such as radiators with thermostatically controlled valves. (3) determine to what extent the addition of a heat pump makes it possible to improve the cost benefit of geothermal heating. When its average characteristics and heating use conditions (price, coefficient of performance, length of utilization, electrical rates, etc.) are taken into account, the heat pump should not be scaled for maximum heating power. Consequently, the program considers several possible sizes, with different installation schemes, and selects for each case the value which corresponds to the lowest cost of heating.

Electrical energy and demand savings from a geothermal heat pump energy savings performance contract at Ft. Polk, LA  

SciTech Connect

At Fort Polk, LA the space conditioning systems of an entire city (4,003 military family housing units) have been converted to geothermal heat pumps (GHP) under an energy savings performance contract. At the same time, other efficiency measures such as compact fluorescent lights (CFLs), low-flow hot water outlets, and attic insulation were installed. Pre- and post-retrofit data were taken at 15-minute intervals on energy flows through the electrical distribution feeders that serve the family housing areas of the post. 15-minute interval data was also taken on energy use from a sample of the residences. This paper summarizes the electrical energy and demand savings observed in this data. Analysis of feeder-level data shows that for a typical year, the project will result in a 25.6 million kWh savings in electrical energy use, or 32.4% of the pre-retrofit electrical consumption in family housing. Results from analysis of building-level data compare well with this figure. Analysis of feeder-level data also shows that the project has resulted in a reduction of peak electrical demand of 6,541 kW, which is 39.6% of the pre-retrofit peak electrical demand. In addition to these electrical savings, the facility is also saving an estimated 260,000 therms per year of natural gas. It should be noted that the energy savings presented in this document are the apparent energy savings observed in the monitored data, and are not to be confused with the contracted energy savings used as the basis for payments. To determine the contracted energy savings, the apparent energy savings may require adjustments for such things as changes in indoor temperature performance criteria, additions of ceiling fans, and other factors.

Comparing maintenance costs of geothermal heat pump systems with other HVAC systems: Preventive maintenance actions and total maintenance costs  

SciTech Connect

Total annual heating, ventilating, and air-conditioning (HVAC) maintenance costs were determined for 20 schools in the Lincoln, Nebraska, Public School District. Each school examined provides cooling to over 70% of its total floor area and relies on one of the following heating and cooling systems to provide the majority of space conditioning: vertical-bore, geothermal heat pumps (GHPs), air-cooled chiller with gas-fired hot water boiler (ACC/GHWB), or water-cooled chiller with gas-fired steam boiler (WCC/GSB). A precursor to this study examined annual costs associated with repair, service, and corrective maintenance activities tracked in a work order database. This follow-up study examines costs associated with preventive maintenance (PM) activities conducted by the district. Annual PM costs were 5.87 {cents}/yr-ft{sup 2} (63.14 {cents}/yr-m{sup 2}) for ACC/GHWB schools, followed by 7.14 {cents}/yr-ft{sup 2} (76.86 {cents}/yr-m{sup 2}) for GHP, 9.82 {cents}/yr-ft{sup 2} (105.39 {cents}/yr-m{sup 2}) for WCC/ GSB, and 12.65 {cents}/yr-ft{sup 2} (136.30 {cents}/yr-m{sup 2}) for WCC/GHWB. The results of the two analyses are combined to produce an estimate of total annual maintenance costs, by system type, for the 20 schools. Total annual maintenance costs were 8.75 {cents}/yr-ft{sup 2} (94.20 {cents}/yr-m{sup 2}) for ACC/GHWB schools, followed by 9.27 {cents}/yr-ft{sup 2} (99.76 {cents}/yr-m{sup 2}) for GHP, 13.54 {cents}/yr-ft{sup 2} (145.49 {cents}/yr-m{sup 2}) for WCC/GSB, and 18.71 {cents}/yr-ft{sup 2} (201.61 {cents}/yr-m{sup 2}) for WCC/GHWB. It should be noted that these costs represent only the trends seen in the maintenance database of the Lincoln School District. Because of differences in the number of schools using each system type, varying equipment age, and the small total number of schools included in the study, the maintenance costs presented here may not be representative of the maintenance costs seen for similar equipment in other locations.

Geothermal hot water pump. Final report  

DOE Green Energy (OSTI)

The design, testing and performance capabilities of a Geothermal Hot Water Pumping System being developed are described. The pumping system is intended to operate submerged in geothermal brine wells for extended periods of time. Such a system confines the hot brine in a closed-loop under pressure to prevent the liquid from flashing into steam, in addition to providing a means for reinjecting cooled water and the contaminants into a return well. The system consists of a single-stage centrifugal pump driven by an oil-cooled, high-speed electric motor with integral heat exchanger. For testing purposes a diesel engine driven 400 Hz generator is used for supplying power to the motor. In some areas where commercial power may not be available, the diesel-generator unit or either a rotating or solid state frequency converter may be used to produce the high frequency power required by the motor. Fabrication of a prototype system and testing of the electric motor at frequencies up to 250 Hz was completed. While testing at 275 Hz it was necessary to terminate the testing when the motor stator was damaged as a result of a mechanical failure involving the motor-dynamometer drive adaptor. Test results, although limited, confirm the design and indicate that the performance is as good, or better than predicted. These results also indicate that the motor is capable of achieving rated performance.

Comparing Maintenance Costs of Geothermal Heat Pump Systems with other HVAC Systems in Lincoln Public Schools: Repair, Service, and Corrective Actions  

DOE Green Energy (OSTI)

The Lincoln Public School District, in Lincoln, Nebraska, recently installed vertical-bore geothermal heat pump systems in four, new, elementary schools. Because the district has consistent maintenance records and procedures, it was possible to study repair, service and corrective maintenance requests for 20 schools in the district. Each school studied provides cooling to over 70% of its total floor area and uses one of the following heating and cooling systems: vertical-bore geothermal heat pumps (GHPs), air-cooled chiller with gas-fired hot water boiler (ACUGHWB), water-cooled chiller with gas-fired hot water boiler (WCCYGHWB), or water-cooled chiller with gas-fired steam boiler (WCUGSB). Preventative maintenance and capital renewal activities were not included in the available database. GHP schools reported average total costs at 2.13 cents/ft{sup 2}-yr, followed by ACC/GHWB schools at 2.88 cents/ft{sup 2}-yr, WCC/GSB schools at 3.73 cents/ft{sup 2}-yr, and WCC/GHWB schools at 6.07 cents/ft{sup 2}-yr. Because of tax-exemptions on material purchases, a reliance on in-house labor, and the absence of preventative maintenance records in the database, these costs are lower than those reported in previous studies. A strong relationship (R{sup 2}=O.52) was found between costs examined and cooling system age: the newer the cooling equipment, the less it costs to maintain.

Mechanical Compression Heat Pumps  

E-Print Network (OSTI)

Mechanical compression heat pumping is not new in industrial applications. In fact, industry history suggests that the theoretical concept was developed before 1825. Heat pump manufacturers gained the support of consultants and end-users when the energy crisis hit this country in 1973. That interest, today, has been dampened because there is a current abundance of the basic sources of industrial energy (namely oil and natural gas). Meanwhile, Mycom used the window of the current opportunities to develop, design and test compressors built to meet the needs of the mechanically demanding industrial heat pump applications which often require high compression ratios and temperatures in excess of 200 degrees F. This paper will review the theoretical foundation for heat pumps and present the mechanical and thermal requirements of the compressors which constitute the heart and soul of the system. It will also provide a quick survey of the available types of compressors for heat pumping and some of the industrial processes where simultaneous heating and cooling proceed along parallel demand paths. The case history will examine the system flexibility and the economic advantages realized in a barley malting process.

Hoosac tunnel geothermal heat source. Final report  

DOE Green Energy (OSTI)

The Hoosac Rail Tunnel has been analyzed as a central element in a district heating system for the City of North Adams. The tunnel has been viewed as a collector of the earth's geothermal heat and a seasonal heat storage facility with heat piped to the tunnel in summer from existing facilities at a distance. Heated fluid would be transported in winter from the tunnel to users who would boost the temperature with individual heat pumps. It was concluded the tunnel is a poor source of geothermal heat. The maximum extractable energy is only 2200 million BTU (20000 gallons of oil) at 58/sup 0/F. The tunnel is a poor heat storage facility. The rock conductivity is so high that 75% of the heat injected would escape into the mountain before it could be recaptured for use. A low temperature system, with individual heat pumps for temperature boost could be economically attractive if a low cost fuel (byproduct, solid waste, cogeneration) or a cost effective seasonal heat storage were available.

Chemical heat pump  

DOE Patents (OSTI)

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to facilitate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer. The heat pump part of the system heats or cools a house or other structure through a combination of evaporation and absorption or, conversely, condensation and desorption, in a pair of containers. A set of automatic controls change the system for operation during winter and summer months and for daytime and nighttime operation to satisfactorily heat and cool a house during an entire year. The absorber chamber is subjected to solar heating during regeneration cycles and is covered by one or more layers of glass or other transparent material. Daytime home air used for heating the home is passed at appropriate flow rates between the absorber container and the first transparent cover layer in heat transfer relationship in a manner that greatly reduce eddies and resultant heat loss from the absorbant surface to ambient atmosphere.

Absorption heat pump system  

DOE Patents (OSTI)

An improvement in an absorption heat pump cycle is obtained by adding adiabatic absorption and desorption steps to the absorber and desorber of the system. The adiabatic processes make it possible to obtain the highest temperature in the absorber before any heat is removed from it and the lowest temperature in the desorber before heat is added to it, allowing for efficient utilization of the thermodynamic availability of the heat supply stream. The improved system can operate with a larger difference between high and low working fluid concentrations, less circulation losses, and more efficient heat exchange than a conventional system.

Geothermal heating for Caliente, Nevada  

DOE Green Energy (OSTI)

Utilization of geothermal resources in the town of Caliente, Nevada (population 600) has been the objective of two grants. The first grant was awarded to Ferg Wallis, part-owner and operator of the Agua Caliente Trailer Park, to assess the potential of hot geothermal water for heating the 53 trailers in his park. The results from test wells indicate sustainable temperatures of 140/sup 0/ to 160/sup 0/F. Three wells were drilled to supply all 53 trailers with domestic hot water heating, 11 trailers with space heating and hot water for the laundry from the geothermal resource. System payback in terms of energy cost-savings is estimated at less than two years. The second grant was awarded to Grover C. Dils Medical Center in Caliente to drill a geothermal well and pipe the hot water through a heat exchanger to preheat air for space heating. This geothermal preheater served to convert the existing forced air electric furnace to a booster system. It is estimated that the hospital will save an average of $5300 in electric bills per year, at the current rate of $.0275/KWH. This represents a payback of approximately two years. Subsequent studies on the geothermal resource base in Caliente and on the economics of district heating indicate that geothermal may represent the most effective supply of energy for Caliente. Two of these studies are included as appendices.

Heat pump apparatus  

DOE Patents (OSTI)

A heat pump apparatus including a compact arrangement of individual tubular reactors containing hydride-dehydride beds in opposite end sections, each pair of beds in each reactor being operable by sequential and coordinated treatment with a plurality of heat transfer fluids in a plurality of processing stages, and first and second valves located adjacent the reactor end sections with rotatable members having multiple ports and associated portions for separating the hydride beds at each of the end sections into groups and for simultaneously directing a plurality of heat transfer fluids to the different groups. As heat is being generated by a group of beds, others are being regenerated so that heat is continuously available for space heating. As each of the processing stages is completed for a hydride bed or group of beds, each valve member is rotated causing the heat transfer fluid for the heat processing stage to be directed to that bed or group of beds. Each of the end sections are arranged to form a closed perimeter and the valve member may be rotated repeatedly about the perimeter to provide a continuous operation. Both valves are driven by a common motor to provide a coordinated treatment of beds in the same reactors. The heat pump apparatus is particularly suitable for the utilization of thermal energy supplied by solar collectors and concentrators but may be used with any source of heat, including a source of low-grade heat.

Industrial and Commercial Heat Pump Applications in the United States  

E-Print Network (OSTI)

The energy crisis of 1973 accelerated the development of large-scale heat pumps in the United States. Since that time, the commercial, institutional, and industrial applications of heat pumps for waste heat recovery have expanded. This paper reviews the trends in heat pump cycle developments and discusses both the closed vapor compression cycle and refrigerants most commonly used and the open-cycle mechanical vapor compression heat pumps. Waste heat sources, heat loads served by heat pumps--and typical applications using heat pumps for large-scale space heating, domestic water heating, and industrial process water heating-- are discussed. Typical installations include commercial applications in hotels, high-rise apartments and condominiums, and office buildings. Institutional installations discussed include hospitals, universities, wastewater treatment plants, and airport terminals. Industrial applications largely center on food processing industries, feedwater heating, metal fabricating, and other industries. Reference is also made to other applications and alternative energy sources now gaining acceptance, including groundwater/geothermal water.

Advanced energy conversion technology can save 50% of this energy and eliminate CFCs completely. Besides saving energy, advanced systems substantially reduce emissions of carbon dioxide (a greenhouse gas), sulfur dioxide, and nitrogen oxides, which contribute to smog and acid rain. These emissions result from the burning of fossil fuels used to generate electricity. The Office of Building Technologies (OBT) of the US Department of Energy supports private industry`s efforts to improve energy efficiency and increase the use of renewable energy in buildings. To help industry, OBT, through the Oak Ridge National Laboratory, is currently working on thermally activated heat pumps. OBT has selected the following absorption heat pump systems to develop: generator-absorber heat-exchange (GAX) cycle for heating-dominated applications in residential and light commercial buildings; double-condenser-coupled (DCC) cycle for commercial buildings. In addition, OBT is developing computer-aided design software for investigating the absorption cycle.

Chemical heat pump  

DOE Patents (OSTI)

A chemical heat pump system is disclosed for use in heating and cooling structures such as residences or commercial buildings. The system is particularly adapted to utilizing solar energy, but also increases the efficiency of other forms of thermal energy when solar energy is not available. When solar energy is not available for relatively short periods of time, the heat storage capacity of the chemical heat pump is utilized to heat the structure, as during nighttime hours. The design also permits home heating from solar energy when the sun is shining. The entire system may be conveniently rooftop located. In order to faciliate installation on existing structures, the absorber and vaporizer portions of the system may each be designed as flat, thin wall, thin pan vessels which materially increase the surface area available for heat transfer. In addition, this thin, flat configuration of the absorber and its thin walled (and therefore relatively flexible) construction permits substantial expansion and contraction of the absorber material during vaporization and absorption without generating voids which would interfere with heat transfer.

Residential space heating cost: geothermal vs conventional systems  

SciTech Connect

The operating characteristics and economies of several representative space heating systems are analyzed. The analysis techniques used may be applied to a larger variety of systems than considered herein, thereby making this document more useful to the residential developer, heating and ventilating contractor, or homeowner considering geothermal space heating. These analyses are based on the use of geothermal water at temperatures as low as 120/sup 0/F in forced air systems and 140/sup 0/F in baseboard convection and radiant floor panel systems. This investigation indicates the baseboard convection system is likely to be the most economical type of geothermal space heating system when geothermal water of at least 140/sup 0/F is available. Heat pumps utilizing water near 70/sup 0/F, with negligible water costs, are economically feasible and they are particularly attractive when space cooling is included in system designs. Generally, procurement and installation costs for similar geothermal and conventional space heating systems are about equal, so geothermal space heating is cost competitive when the unit cost of geothermal energy is less than or equal to the unit cost of conventional energy. Guides are provided for estimating the unit cost of geothermal energy for cases where a geothermal resource is known to exist but has not been developed for use in residential space heating.

Save by absorption heat pumping  

SciTech Connect

The author compares absorption heat pumping (AHP) to mechanical vapor compressor (MVC) heat pumping. The moving part of the AHP is a pump easy to maintain and inexpensive to spare. The mechanical component of the MVC is a vapor compressor which requires more maintenance and is cost-prohibitive to spare. Also, in the MVC system, a purified product stream is heat pumped in an open compressor, thus risking product contamination. In the AHP system, the cold and hot utilities are heat pumped. Therefore, product integrity with an AHP system is well protected as in a conventional fractionation column.

The technical feasibility of heating greenhouses with geothermal heat is established. Off-the-shelf equipment suitable for geothermal heating is readily available. A procedure is given to economically examine a geothermal site for its suitability. Generally, geothermal heating systems are capital intensive. Where the geothermal energy is free the geothermal system is very attractive and where the cost of geothermal heat is the same as other energy, Btu/$, geothermal heat is unattractive.

Modeling of Heat Transfer in Geothermal Heat Exchangers  

E-Print Network (OSTI)

Ground-coupled heat pump (GCHP) systems have been gaining increasing popularity for space conditioning in residential and commercial buildings. The geothermal heat exchanger (GHE) is devised for extraction or injection of thermal energy from/into the ground. This paper summarizes the authors' studies on heat transfer in ground-coupled heat pump systems. Taking the fluid axial convective heat transfer and thermal ôshort-circuitingö among U-tube legs into account, a quasi-3-D model has been solved for heat transfer inside boreholes. The transient 2-D temperature response in a semi-infinite medium with a line-source of finite length has also been derived for heat conduction outside boreholes. In order to investigate the impact of groundwater advection on the performance of ground heat exchangers, an analytical solution is obtained for a line heat source in an infinite porous medium with groundwater advection. These explicit expressions have more solid theoretical basis, and can be easily incorporated into computer programs for thermal analysis and engineering design of ground heat exchangers.

Efficiency of unitary heat pumps  

SciTech Connect

The efficiencies of approximately 500 unitary heat pumps, from 30 different manufacturers, certified by the Air Conditioning and Refrigeration Institute (ARI) were examined. The certified units account for about 90% of all unitary heat pumps manufactured in the U.S. with a rated cooling capacity below 135,000 Btu/hr, and thus represent a comprehensive data file of the efficiencies of unitary heat pumps offered for sale in the U.S. A computer was used to group the heat pumps according to type and capacity, and to calculate their coefficients of performance (COP) using the data contained in ARI current Directory (April 1 to July 31, 1973) of Certified Unitary Heat Pumps. The results show that the COP of the heat pumps varied from a low of 1.5 to a high of 3.15 or a factor of 2 between the lowest and the highest efficiency, and that the average COP was 2.1 in cooling and 2.4 in heating. The variations of COP with heat pump size, type, manufacturer and outdoor temperature are presented.

Economics of geothermal direct-heat applications  

DOE Green Energy (OSTI)

Cost and production data from five commercial-scale geothermal direct-heat application projects are reviewed. Unit costs of geothermal energy under a variety of assumptions about production levels, costs, tax treatment, financial structure, and cost of capital are calculated and compared to prices of conventional fuels which would be displaced over the life of a geothermal project. Geothermal energy is found to be less costly than distillate fuel oil for all cases examined and cheaper than natural gas in many cases.

Geothermal heating system and method of installing the same  

SciTech Connect

A geothermal system and method of installing the same comprises the steps successively driving a drive pipe structure vertically into the ground at a plurality of locations so that a major portion of the length of the drive pipe structure is located below the frost line. An elongate geothermal pipe having closed ends is inserted into the drive pipe structure and its lower end is interlocked with a drive point device located at the lower end of the drive pipe structure. Thereafter, when the drive pipe is removed, the geothermal pipe remains anchored to the drive point. The geothermal pipes are connected together by conduits and connected to a heat pump so that a heat exchange liquid will be circulated through the system.

Solar assisted heat pump on air collectors: A simulation tool  

Science Conference Proceedings (OSTI)

The heating system of the bioclimatic building of the Greek National Centre for Renewable Energy Sources (CRES) comprises two heating plants: the first one includes an air source heat pump, Solar Air Collectors (SACs) and a heat distribution system (comprising a fan coil unit network); the second one is, mainly, a geothermal heat pump unit to cover the ground floor thermal needs. The SAC configuration as well as the fraction of the building heating load covered by the heating plant are assessed in two operation modes; the direct (hot air from the collectors is supplied directly to the heated space) and the indirect mode (warm air from the SAC or its mixture with ambient air is not supplied directly to the heated space but indirectly into the evaporator of the air source heat pump). The technique of the indirect mode of heating aims at maximizing the efficiency of the SAC, saving electrical power consumed by the compressor of the heat pump, and therefore, at optimizing the coefficient of performance (COP) of the heat pump due to the increased intake of ambient thermal energy by means of the SAC. Results are given for three research objectives: assessment of the heat pump efficiency whether in direct or indirect heating mode; Assessment of the overall heating plant efficiency on a daily or hourly basis; Assessment of the credibility of the suggested simulation model TSAGAIR by comparing its results with the TRNSYS ones.

East Mesa geothermal pump test facility (EMPTF). Final report  

DOE Green Energy (OSTI)

The design, fabrication and installation of a geothermal pump test facility (EMPFT) at the DOE geothermal site at East Mesa, California which is capable of testing 70 to 750 horsepower downwell pumps in a controlled geothermal environment were completed. The facility consists of a skid-mounted brine control module, a 160 foot below test well section, a hydraulic turbine for power recovery, a gantry-mounted hoist for pump handling and a 3-phase, 480 VAC, 1200 amp power supply to handle pump electric requirements. Geothermal brine is supplied to the EMPTF from one of the facility wells at East Mesa. The EMPTF is designed with a great amount of flexibility. The 20-inch diameter test well can accommodate a wide variety of pumps. The controls are interactive and can be adjusted to obtain a full complement of pump operation data, or set to maintain constant conditions to allow long-term testing with a minimum of operator support. The hydraulic turbine allows the EMPTF user to recover approximately 46% of the input pump power to help defray the operating cost of the unit. The hoist is provided for material handling and pump servicing and reduces the equipment that the user must supply for pump installation, inspection and removal.

Midland, South Dakota geothermal district heating  

SciTech Connect

This article describes historical aspects and present usage of geothermal district heating systems in the town of Midland, South Dakota. The use of geothermal resources exists due to a joint venture between the school district and the city back in the early 1960`s. A total of approximately 30,000 square feet (2800 square meters) of floor space is heated using geothermal energy in Midland. This provides an estimated annual saving in propane cost of $15,000 to the community.

Downwell pump reliability: Geothermal experience update: Final report  

DOE Green Energy (OSTI)

Geothermal resources with temperatures between 250/sup 0/ and 360/sup 0/F (121/sup 0/C and 182/sup 0/C) are prime candidates for binary-cycle power generation, and constitute about 80% of the power-capable resources in the United States. The successful exploitation of these resources requires reliable high-capacity downwell brine production pumps, but earlier experience showed that high-capacity, high-temperature geothermal production pumps had many problems which resulted in a mean time-to-failure (MTTF) of less than 1000 h. However, steady progress has been made since 1981, and a large body of experience has been acquired by three geothermal binary plants. This survey of high-temperature geothermal downwell pump users and manufacturers updates a prior survey (AP-3572) completed in early 1983. This survey traces the development of lineshaft pump technology from the late 1970s to the present (mid-1987), detailing the advances in design, materials selection, and operating practices. Case histories of 72 lineshaft pumps installed at three geothermal binary plants since late 1981 are documented, including some detailed cause of failure reports. In the recent past, pump lives in excess of 7000 h have become common, but a high continuing rate of premature failures resulted in a mean time-to-failure (MTTF) of about 5000 h. Based on recent advances which appear likely to eliminate most premature failures, the estimated near-term MTTF will be on the order of 8000 h. The survey found almost no development of high-temperature geothermal electric submersible pumps (ESP's) or close-coupled downwell hydraulic turbopumps, and concluded that considerable development and demonstration will be needed before these technologies are able to compete with existing high-temperature geothermal lineshaft pump technology. 36 refs., 10 figs., 25 tabs.

Industrial Heat Pump Case Study  

E-Print Network (OSTI)

An open-cycle heat pump was retrofitted to a single-effect, recirculating-type evaporator used for reducing the water content of whey (a liquid by-product from cheese production). The purpose of the retrofit was to reduce the energy costs associated with operating the evaporator. The open-cycle heat pump design uses an electrically driven centrifugal compressor to recover the latent heat of the water vapor generated by the evaporator. (Steam was the original heat source but is now only needed for start-up.) This concept is sometimes called mechanical vapor compression (MVC) or mechanical vapor recompression (MVR). A variety of engineering issues have to be resolved to integrate a heat pump into an evaporator system. This paper identifies key issues and describes how they were resolved for this particular process. Issues include choice of compressor, motor selection, control strategy, impact of heat pump on heat exchanger surface area requirements and related issues, and methods for protecting the compressor from surge, droplet ingestion, and other hazards.

Klamath County YMCA geothermal heating project environmental assessment  

DOE Green Energy (OSTI)

The YMCA Geothermal Heating project proposes to obtain approximately 57% of the total facility energy usage through direct application of the Klamath Falls KGRA. This will be accomplished through the design and construction of a retrofit and injection system for the utilization of an existing 110/sup 0/F geothermal energy source at the project site. The existing 2016 foot well will be outfitted with a turbine pump with variable speed drive. The well head will be enclosed by a 10' x 10' building. The geothermal fluid, pumped at a peak rate of 350 gpm will be transported to the YMCA Facility through 5'' diameter schedule 40 black iron pipe fitted with victaulic couplings for expansion. All underground supply pipes will be equipped with magnesium anodes for galvaic protection and will be insulted with 1'' thick calcium silicate insulation, with two layers of 45 number roofing felt applied with asphaltic compound. All supply lines within the building will be insulated with 1'' fiberglass insulation material with a cloth jacket. The fluids will pass through a heating coil and heat exchanger system to provide heat for the 30,000 square foot YMCA facility as well as for the 90,000 gallon swimming pool. The spent geothermal fluids will then be conveyed through a 4'' black iron return pipe to be returned to an acceptable aquifer through the 1500 foot injection well.

Absorption-heat-pump system  

DOE Patents (OSTI)

An improvement in an absorption heat pump cycle is obtained by adding adiabatic absorption and desorption steps to the absorber and desorber of the system. The adiabatic processes make it possible to obtain the highest temperature in the absorber before any heat is removed from it and the lowest temperature in the desorber before heat is added to it, allowing for efficient utilization of the thermodynamic availability of the heat supply stream. The improved system can operate with a larger difference between high and low working fluid concentrations, less circulation losses, and more efficient heat exchange than a conventional system.

Heat deliverability of homogeneous geothermal reservoirs  

DOE Green Energy (OSTI)

For the last two decades, the petroleum industry has been successfully using simple inflow performance relationships (IPR's) to predict oil deliverability. In contrast, the geothermal industry lacked a simple and reliable method to estimate geothermal wells' heat deliverability. To address this gap in the standard geothermal-reservoir-assessment arsenal, we developed generalized dimensionless geothermal inflow performance relationships (GIPR's). These ''reference curves'' may be regarded as an approximate general solution of the equations describing the practically important case of radial 2-phase inflow. Based on this approximate solution, we outline a straightforward approach to estimate the reservoir contribution to geothermal wells heat and mass deliverability for 2-phase reservoirs. This approach is far less costly and in most cases as reliable as numerically modeling the reservoir, which is the alternative for 2-phase inflow.

To address this gap in the standard geothermal-reservoir-assessment arsenal, we developed generalized dimensionless geothermal inflow performance relationships (GIPR's). These ''reference curves'' may be regarded as an approximate general solution of the equations describing the practically important case of radial 2-phase inflow. Based on this approximate solution, we outline a straightforward approach to estimate the reservoir contribution to geothermal wells heat and mass deliverability for 2-phase reservoirs. This approach is far less costly and in most cases as reliable as numerically modeling the reservoir, which is the alternative for 2-phase inflow.

Geothermal district heating: basics to success  

DOE Green Energy (OSTI)

A district heating system using geothermal energy is a viable and economic option in many locations. A successful system, however, is dependent upon a variety of factors, and it is the purpose of this presentation to accent those items that are proving to have significant impact upon the successful operation of geothermal district heating systems. (These lessons can also apply to other sources of energy.) The six major basics to success that are discussed in this paper are economic viability, an adequate geothermal resource, simplicity of design, a closed loop system, a local champion, and good public relations.

Advanced Electric Submersible Pump Design Tool for Geothermal Applications  

DOE Green Energy (OSTI)

Electrical Submersible Pumps (ESPs) present higher efficiency, larger production rate, and can be operated in deeper wells than the other geothermal artificial lifting systems. Enhanced Geothermal Systems (EGS) applications recommend lifting 300 C geothermal water at 80kg/s flow rate in a maximum 10-5/8-inch diameter wellbore to improve the cost-effectiveness. In this paper, an advanced ESP design tool comprising a 1D theoretical model and a 3D CFD analysis has been developed to design ESPs for geothermal applications. Design of Experiments was also performed to optimize the geometry and performance. The designed mixed-flow type centrifugal impeller and diffuser exhibit high efficiency and head rise under simulated EGS conditions. The design tool has been validated by comparing the prediction to experimental data of an existing ESP product.

Waste heat rejection from geothermal power stations  

DOE Green Energy (OSTI)

This study of waste heat rejection from geothermal power stations is concerned only with the heat rejected from the power cycle. The heat contained in reinjected or otherwise discharged geothermal fluids is not included with the waste heat considered here. The heat contained in the underflow from the flashtanks in such systems is not considered as part of the heat rejected from the power cycle. By following this definition of the waste heat to be rejected, various methods of waste heat dissipation are discussed without regard for the particular arrangement to obtain heat from the geothermal source. Recent conceptual design studies made for 50-MW(e) geothermal power stations at Heber and Niland, California, are of particular interst. The former uses a flashed-steam system and the latter a binary cycle that uses isopentane. In last-quarter 1976 dollars, the total estimated capital costs were about $750/kW and production costs about 50 mills/kWhr. If wet/dry towers were used to conserve 50% of the water evaporation at Heber, production costs would be about 65 mills/kWhr.

Geothermal direct heat applications program summary  

DOE Green Energy (OSTI)

The use of geothermal energy for direct heat purposes by the private sector within the US has been quite limited to date. However, there is a large potential market for thermal energy in such areas as industrial processing, agribusiness, and space/water heating of commercial and residential buildings. Technical and economic information is needed to assist in identifying prospective direct heat users and to match their energy needs to specific geothermal reservoirs. Technological uncertainties and associated economic risks can influence the user's perception of profitability to the point of limiting private investment in geothermal direct applications. To stimulate development in the direct heat area, the Department of Energy, Division of Geothermal Energy, issued two Program Opportunity Notices (PON's). These solicitations are part of DOE's national geothermal energy program plan, which has as its goal the near-term commercialization by the private sector of hydrothermal resources. Encouragement is being given to the private sector by DOE cost-sharing a portion of the front-end financial risk in a limited number of demonstration projects. The twenty-two projects summarized herein are direct results of the PON solicitations.

Waste heat rejection from geothermal power stations  

DOE Green Energy (OSTI)

Waste heat rejection systems for geothermal power stations have a significantly greater influence on plant operating performances and costs than do corresponding systems in fossil- and nuclear-fueled stations. With thermal efficiencies of only about 10%, geothermal power cycles can reject four times as much heat per kilowatt of output. Geothermal sites in the United States tend to be in water-short areas that could require use of more expensive wet/dry or dry-type cooling towers. With relatively low-temperature heat sources, the cycle economics are more sensitive to diurnal and seasonal variations in sink temperatures. Factors such as the necessity for hydrogen sulfide scrubbers in off-gas systems or the need to treat cooling tower blowdown before reinjection can add to the cost and complexity of goethermal waste heat rejection systems. Working fluids most commonly considered for geothermal cycles are water, ammonia, Freon-22, isobutane, and isopentane. Both low-level and barometric-leg direct-contact condensers are used, and reinforced concrete has been proposed for condenser vessels. Multipass surface condensers also have wide application. Corrosion problems at some locations have led to increased interest in titanium tubing. Studies at ORNL indicate that fluted vertical tubes can enhance condensing film coefficients by factors of 4 to 7.

Heber geothermal binary demonstration project: Unavailability distributions for principal pumps  

DOE Green Energy (OSTI)

The purpose of this study has been to review data sources relevant to the failure rate and mean time to repair for the principal pumps of the Heber geothermal project. Based upon that review the distributions of failure rates, repair times and pump unavailability were established. A total of 16 pumps are represented in this study. The method used to develop data distributions has been to first review as many sources of pump data as are currently available. This review was followed by a study of the features of the pumps specified for the Heber installation and the effects of operation and the environment on those features as they relate to anticipated failure rates and repair times. From this, determinations were made for mean failure rate and repair time values appropriate to specific Heber pumps. Range factors are then selected and used to establish the expected variability of the data. Failure rates and repair times were then combined to obtain the unavailability distribution of each type of pump.

Convective heat transport in geothermal systems  

DOE Green Energy (OSTI)

Most geothermal systems under exploitation for direct use or electrical power production are of the hydrothermal type, where heat is transferred essentially by convection in the reservoir, conduction being secondary. In geothermal systems, buoyancy effects are generally important, but often the fluid and heat flow patterns are largely controlled by geologic features (e.g., faults, fractures, continuity of layers) and location of recharge and discharge zones. During exploitation, these flow patterns can drastically change in response to pressure and temperature declines, and changes in recharge/discharge patterns. Convective circulation models of several geothermal systems, before and after start of fluid production, are described, with emphasis on different characteristics of the systems and the effects of exploitation on their evolution. Convective heat transport in geothermal fields is discussed, taking into consideration (1) major geologic features; (2) temperature-dependent rock and fluid properties; (3) fracture- versus porous-medium characteristics; (4) single- versus two-phase reservoir systems; and (5) the presence of noncondensible gases.

Ground Loops for Heat Pumps and Refrigeration  

E-Print Network (OSTI)

Ground loops are used for water source heat pumps. Refrigeration can be put on a ground loop. Water-cooled condensing units are more efficient than air-cooled, and they can be put indoors. Indoor location makes piping for desuperheater hot water easy. Since refrigeration equipment runs more than heat pumps, energy savings can be large for ground-coupled refrigeration. The paper presents a design procedure for ground loops for heat pumps, hot water, ice machines, and water-cooled refrigeration. It gives an overview of the commercial ground-coupled systems in Louisiana that have both refrigeration and heat pumps. Systems vary from small offices to a three-story office building with 187 tons. A chain of hamburger outlets uses total ground-coupling in all of its stores. A grocery store has ground-coupling for heat pumps and refrigeration. Desuperheaters provide 80 percent of the hot water for a coin laundry in the same building. A comparison of energy costs in a bank with a ground-coupled heat pump system to a similar bank with air-conditioning and gas for heat revealed a 31 percent reduction in utility costs for the ground-coupled building. Two buildings of the Mississippi Power and Light Co. have ground-coupled heat pumps in one, and high efficiency air source heat pumps in the other. Energy savings in nine months was 60,000 kWh (25 percent), and electric peak demand was reduced 42 kW (35 percent).

Lightning dock geothermal space heating project, Lightning Dock KGRA, New Mexico. Final report  

DOE Green Energy (OSTI)

The proposed project was to take the existing geothermal greenhouse and home heating systems, which consisted of pumping geothermal water and steam through passive steam heaters, and convert the systems to one using modern heat exchange units. It was proposed to complete the existing unfinished, re-inforced glass side wall, wood framed structure, as a nursery lath house, the purpose of which would be to use geothermal water in implementing university concepts on the advantages of bottom heat to establish hardy root systems in nursery and bedding plants. The use of this framework was abandoned in favor of erecting new structures for the proposed purpose. The final project of the proposal was the establishment of a drip irrigation system, to an area just west of the existing greenhouse and within feet of the geothermal well. Through this drip irrigation system geothermal water would be pumped, to prevent killing spring frosts. The purpose of this area of the proposal is to increase the potential use of existing geothermal waters of the Lightning Dock KGRA, in opening a new geothermal agri-industry which is economically feasible for the area and would be extremely energy efficient.

Wind energy/geothermic/solar heating system. Final report  

SciTech Connect

I've observed three distinct ''camps'' of renewable energy resources; WIND, Geothermic, and Solar. None of the three are completely adequate for the NE by themselves. I observe little effort to combine them to date. My objective has been to demonstrate that the three can be combined in a practical system. To mitagate the high cost and poor payback for individual residences, I believe neighborhoods of 4 to 5 homes, apartment complexes or condominiums could form an Energy Association alloting a piece of ground (could be a greenbelt) which would contain the well or wells, solar boosted underground water storage and the Solar banks. These are the high cost items which could be prorated and ammortized by the Association. Easements would permit each residence underground insulated water lines for individual heat pump conversions to existing forced air furnaces. Where regulations permit, an individual home could erect his own windmill to belt drive his freon compressor. With or without the optional windmill the water to freon heat pump with its solar boosts on the well water, will enjoy COP's (coefficient of Performances or times better than electric resistance heat) beyond anything on the market today. In a neighborhood energy association, all trenching could be done together all plumbing could be one contract and they could qualify for quantity discounts on heat pump units, chillers and components and installation.

Geothermal field tests: heat exchanger evaluation  

DOE Green Energy (OSTI)

Results of the heat exchanger tests conducted on a scale model of a heat exchanger that has been designed and fabricated for the Geothermal Test Facility show that this exchanger will lose 60% of its heat transfer capability and fall below design requirements after 92 hours of operation. When the test exchanger was clean and operating as close as possible to design conditions, its overall heat transfer coefficient was 426 BTU/hr-ft/sup 2/ - /sup 0/f. when calculating in the fouling factor of .0035 this gave a design coefficient of 171 BTU/hr-ft/sup 2/ - /sup 0/f which was reached after less than four days of steady state operation. Thermal shocking of the test heat exchanger once each hour while the exchanger was operating at design conditions had no effect on scale removal or heat transfer. Results of tube cleaning showed that chemical treatment with 30% hydrochloric acid followed by a high pressure water jet (6000 psig), was effective in removing scale from tubes contacted with geothermal brine. After cleaning, the tubes were examined and some pitting was observed throughout the length of one tube.

Geothermal Direct Heat Applications Program Summary  

DOE Green Energy (OSTI)

Because of the undefined risk in the development and use of geothermal energy as a thermal energy source, the Department of Energy Division of Geothermal Energy solicited competitive proposals for field experiments in the direct use of geothermal energy. Twenty-two proposals were selected for cost-shared funding with one additional project co-funded by the State of New Mexico. As expected, the critical parameter was developing a viable resource. So far, of the twenty resources drilled, fourteen have proved to be useful resources. These are: Boise, Idaho; Elko heating Company in Nevada; Pagosa Springs, Colorado; Philip School, Philip, South Dakota; St. Mary's Hospital, Pierre, South Dakota; Utah Roses near Salt Lake City; Utah State Prison, Utah; Warm Springs State Hospital, Montana; T-H-S Hospital, Marlin, Texas; Aquafarms International in the Cochella Valley, California; Klamath County YMCA and Klamath Falls in Oregon; Susanville, California and Monroe, utah. Monroe's 164 F and 600 gpm peak flow was inadequate for the planned project, but is expected to be used in a private development. Three wells encountered a resource insufficient for an economical project. These were Madison County at Rexburg, Idaho; Ore-Ida Foods at Ontario, Oregon and Holly Sugar at Brawley, California. Three projects have yet to confirm their resource. The Navarro College well in Corsicana, Texas is being tested; the Reno, Moana, Nevada well is being drilled and the El Centro, California well is scheduled to be drilled in January 1982. The agribusiness project at Kelly Hot Springs was terminated because a significant archeological find was encountered at the proposed site. The Diamond Ring Ranch in South Dakota, and the additional project, Carrie Tingley Hospital in Truth or Consequences, New Mexico both used existing wells. The projects that encountered viable resources have proceeded to design, construct, and in the most advanced projects, to operate geothermal systems for district heating, space heating, grain drying and aquaculture.

Geothermal direct heat applications program summary  

DOE Green Energy (OSTI)

In 1978, the Department of Energy Division of Geothermal and Hydropower Technologies initiated a program to accelerate the direct use of geothermal energy, in which 23 projects were selected. The projects, all in the western part of the US, cover the use of geothermal energy for space conditioning (heating and cooling) and agriculture (aquaculture and greenhouses). Initially, two projects were slated for industrial processing; however, because of lack of geothermal resources, these projects were terminated. Of the 23 projects, seven were successfully completed, ten are scheduled for completion by the end of 1983, and six were terminated for lack of resources. Each of the projects is being documented from its inception through planning, drilling, and resource confirmation, design, construction, and one year of monitoring. The information is being collected, evaluated, and will be reported. Several reports will be produced, including detailed topical reports on economics, institutional and regulatory problems, engineering, and a summary final report. To monitor progress and provide a forum for exchange of information while the program is progressing, semiannual or annual review meetings have been held with all project directors and lead engineers for the past four years. This is the sixth meeting in that series. Several of the projects which have been terminated are not included this year. Overall, the program has been very successful. Valuable information has been gathered. problems have been encountered and resolved concerning technical, regulatory, and institutional constraints. Most projects have been proven to be economical with acceptable pay-back periods. Although some technical problems have emerged, they were resolved with existing off-the-shelf technologies and equipment. The risks involved in drilling for the resource, the regulatory constraints, the high cost of finance, and large front-end cost remain the key obstacles to the broad development of geothermal direct use applications.

Direct utilization of geothermal energy for space and water heating at Marlin, Texas. Final report  

DOE Green Energy (OSTI)

The Torbett-Hutchings-Smith Memorial Hospital geothermal heating project, which is one of nineteen direct-use geothermal projects funded principally by DOE, is documented. The five-year project encompassed a broad range of technical, institutional, and economic activities including: resource and environmental assessments; well drilling and completion; system design, construction, and monitoring; economic analyses; public awareness programs; materials testing; and environmental monitoring. Some of the project conclusions are that: (1) the 155/sup 0/F Central Texas geothermal resource can support additional geothermal development; (2) private-sector economic incentives currently exist, especially for profit-making organizations, to develop and use this geothermal resource; (3) potential uses for this geothermal resource include water and space heating, poultry dressing, natural cheese making, fruit and vegetable dehydrating, soft-drink bottling, synthetic-rubber manufacturing, and furniture manufacturing; (4) high maintenance costs arising from the geofluid's scaling and corrosion tendencies can be avoided through proper analysis and design; (5) a production system which uses a variable-frequency drive system to control production rate is an attractive means of conserving parasitic pumping power, controlling production rate to match heating demand, conserving the geothermal resource, and minimizing environmental impacts.

Planning analyses for geothermal district heating  

DOE Green Energy (OSTI)

Methodology and data bases are described which can provide a comprehensive planning assessment of the potential for geothermal district heating in any US market. This economic systems model encompasses life-cycle costing over a period of rising competitive fuel prices, it addresses the expansion and financing of a district system over time, and it includes an overall optimization of system design. The elemental area for all analyses is the census tract, for which published data allow estimation of residential and commercial heating demands, building retrofit requirements, and competitive fuel consumption and cost. A system type design, an appropriate hot water district piping system, and costing of heat supply is performed for groups of contiguous tracts in any urban market. Groups are aggregated, in decreasing benefit to cost order, to achieve optimal systems. A specific application for Salt Lake City, Utah, is also described.

Projecting market demand for residential heat pumps  

SciTech Connect

Primarily because of technological improvements and sharp increases in energy prices after the 1970s energy crises, the sale of residential electric heat pumps rose ninefold from 1970 to 1983. This report describes current and future market demand for heat pumps used for space heating and cooling. A three-step approach was followed. In the first step, the historical growth of residential electric heat pumps was analyzed, and factors that may have affected market growth were examined. Also examined were installation trends of heat pumps in new single-family and multifamily homes. A market segmentation analysis was used to estimate market size by categories. In the second step, several methods for forecasting future market demand were reviewed and evaluated to select the most suitable one for this study. The discrete-choice approach was chosen. In the third step, a market penetration model based on selected discrete-choice methods was developed to project heat pump demand in key market segments such as home type (single-family or multifamily), new or existing construction, and race-ethnic origin of household (black, Hispanic, or white).

Cold Climates Heat Pump Design Optimization  

SciTech Connect

Heat pumps provide an efficient heating method; however they suffer from sever capacity and performance degradation at low ambient conditions. This has deterred market penetration in cold climates. There is a continuing effort to find an efficient air source cold climate heat pump that maintains acceptable capacity and performance at low ambient conditions. Systematic optimization techniques provide a reliable approach for the design of such systems. This paper presents a step-by-step approach for the design optimization of cold climate heat pumps. We first start by describing the optimization problem: objective function, constraints, and design space. Then we illustrate how to perform this design optimization using an open source publically available optimization toolbox. The response of the heat pump design was evaluated using a validated component based vapor compression model. This model was treated as a black box model within the optimization framework. Optimum designs for different system configurations are presented. These optimum results were further analyzed to understand the performance tradeoff and selection criteria. The paper ends with a discussion on the use of systematic optimization for the cold climate heat pump design.

Geothermal heating from Pinkerton Hot Springs at Colorado Timberline Academy, Durango, Colorado. Final technical report  

DOE Green Energy (OSTI)

The efforts to establish a greater pool of knowledge in the field of low temperature heat transfer for the application of geothermal spring waters to space heating are described. A comprehensive set of heat loss experiments involving passive radiant heating panels is conducted and the results presented in an easily interpretable form. Among the conclusions are the facts that heating a 65 to 70 F/sup 0/ space with 90 to 100 F/sup 0/ liquids is a practical aim. The results are compared with the much lower rates published in the American Society of Heating Refrigeration and Air Conditioning Engineers SYSTEMS, 1976. A heat exchange chamber consisting of a 1000 gallon three compartment, insulated and buried tank is constructed and a control and pumping building erected over the tank. The tank is intended to handle the flow of geothermal waters from Pinkerton Hot Springs at 50 GPM prior to the wasting of the spring water at a disposal location. Approximately 375,000 Btu per hour should be available for heating assuming a 15 F/sup 0/ drop in water temperature. A combination of the panel heat loss experiments, construction of the heat exchange devices and ongoing collection of heat loss numbers adds to the knowledge available to engineers in sizing low temperature heat systems, useful in both solar and geothermal applications where source temperature may be often below 110 F/sup 0/.

Experimental Research of Air Source Heat Pump Frosting and Defrosting in a Double Stage-Coupling Heat Pump  

E-Print Network (OSTI)

In a double stage-coupling heat pump, comprising an air source and water loop heat pump, the 13~20 ? low temperature water is supplied to the water loop heat pump unit. The water loop heat pump can extract heat from the water and heat the indoor air. The most common method of air source heat pump frost removal is reverse-cycle defrost. During the defrosting operation, the heat pump runs in the cooling mode. The defrost process is accomplished by reversing the normal heating mode. In this paper, the effect of the heat storage tank to the air source heat pump defrosting is test. Owing to the existence of the heat storage tank, thermal inertia of the loop is relatively high. The frosting and defrosting course of the air source heat pump have little effect on the room temperature.

Electric Adsorption Heat Pump for Electric Vehicles: Electric-Powered Adsorption Heat Pump for Electric Vehicles  

Science Conference Proceedings (OSTI)

HEATS Project: PNNL is developing a new class of advanced nanomaterial called an electrical metal organic framework (EMOF) for EV heating and cooling systems. The EMOF would function similar to a conventional heat pump, which circulates heat or cold to the cabin as needed. However, by directly controlling the EMOF's properties with electricity, the PNNL design is expected to use much less energy than traditional heating and cooling systems. The EMOF-based heat pumps would be light, compact, efficient, and run using virtually no moving parts.

Hot dry rock geothermal heat extraction  

DOE Green Energy (OSTI)

A man-made geothermal reservoir has been created at a depth of 2.7 km in hot, dry granite by hydraulic fracturing. The system was completed by directionally drilling a second well in close proximity with the top of the vertical fracture. In early 1978 heat was extracted from this reservoir for a period of 75 days. During this period thermal power was produced at an average rate of 4 MW(t). Theoretical analysis of th measured drawdown suggests a total fracture heat transfer area of 16,000 m/sup 2/. Viscous impedance to through-flow declined continuously so that at the end of the experiment this impedance was only one-fifth its initial value. Water losses to the surrounding rock formation also decreased continuously, and eventually this loss rate was less than 1% of the circulated flow rate. Geochemical analyses suggest that, with scale up of the heat transfer area and deeper, hotter reservoirs, hot dry rock reservoirs can ultimately produce levels of power on a commercial scale.

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

Swimming Pool Heaters Swimming Pool Heaters Heat Pump Swimming Pool Heaters May 29, 2012 - 1:49pm Addthis How a heat pump works. How a heat pump works. How They Work Heat pumps use electricity to capture heat and move it from one place to another. They don't generate heat. As the pool pump circulates the swimming pool's water, the water drawn from the pool passes through a filter and the heat pump heater. The heat pump heater has a fan that draws in the outside air and directs it over the evaporator coil. Liquid refrigerant within the evaporator coil absorbs the heat from the outside air and becomes a gas. The warm gas in the coil then passes through the compressor. The compressor increases the heat, creating a very hot gas that then passes through the condenser. The condenser transfers the heat from the hot gas to the cooler pool water circulating

Advanced Chemical Heat Pumps Using Liquid-Vapor Reactions  

E-Print Network (OSTI)

Chemical heat pumps utilizing liquid-vapor reactions can be configured in forms analogous to electric drive vapor-compression heat pumps and heat activated absorption heat pumps. Basic thermodynamic considerations eliminate some heat pumps and place restrictive working fluid requirements on others, but two thermodynamically feasible systems have significant potential advantage over conventional technology. An electric drive reactive heat pump can use smaller heat exchangers and compressor than a vapor-compression machine, and have more flexible operating characteristics. A waste heat driven heat pump (temperature amplifier) using liquid-vapor chemical reactions- can operate with higher coefficient of performance and smaller heat exchangers than an absorption temperature amplifying heat pump. Higher temperatures and larger temperature lifts should also be possible.

Solar-powered turbocompressor heat pump system  

DOE Patents (OSTI)

The turbocompressor comprises a power turbine and a compressor turbine having respective rotors and on a common shaft, rotatably supported by bearings. A first working fluid is supplied by a power loop and is expanded in the turbine. A second working fluid is compressed in the turbine and is circulated in a heat pump loop. A lubricant is mixed with the second working fluid but is excluded from the first working fluid. The bearings are cooled and lubricated by a system which circulates the second working fluid and the intermixed lubricant through the bearings. Such system includes a pump, a thermostatic expansion valve for expanding the working fluid into the space between the bearings, and a return conduit system for withdrawing the expanded working fluid after it passes through the bearings and for returning the working fluid to the evaporator. A shaft seal excludes the lubricant from the power turbine. The power loop includes a float operable by liquid working fluid in the condenser for controlling a recirculation valve so as to maintain a minimum liquid level in the condenser, while causing a feed pump to pump most of the working fluid into the vapor generator. The heat pump compressor loop includes a float in the condenser for operating and expansion valve to maintain a minimum liquid working fluid level in the condenser while causing most of the working fluid to be expanded into the evaporator.

Artificial Heart Pump (Additional Endogenous Heat) Program  

SciTech Connect

Three plutonium-238 radioisotope-powered heat sources were developed and fabricated at Mound Laboratory for use by Thermo Electron Engineering Corporation (TEECO) in the Artificial Heart Pump (Additional Endogenous Heat) Program. These sources contained doubly encapsulated plutonum-238 metal; two had a thermal power of 15(+2-0) W and one had 25(+0-2) W. Details of the design, fabrication, and testing of the heat sources are given in this report. Two of the heat sources (one 15-W and one 25-W) were shipped to TEECO for use with special heat exchangers in implantation experiments on dogs at Boston City Hospital. These tests have been under way since July, 1967. The third heat source (15-W) was fabricated for in-house testing at Mound Laboratory.

Potential for heating western tree seedling greenhouses with geothermal energy  

DOE Green Energy (OSTI)

The technology to apply geothermal energy to greenhousing is available. Geothermal energy is compatible with greenhouse heat exchange hardware, and it is abundant in the western United States. Geothermal resources suitable for greenhousing are natural springs, deep hot water or steam wells, and waste water from electrical power generating plants. Factors influencing greenhouse heating needs include climate, elevation, structure, and growing regime, as well as the attributes of the geothermal energy source: heat, quantity, quality. Greenhouse sites should be evaluated for suitability, size, availability of labor supply, markets, etc. Problems exist in developing any new energy source, but a sound economic assessment based on good engineering and geological advice will illustrate advantages and problems. When considering geothermal energy as an alternative energy source these steps are recommended: (1) Determine the geographic region greenhouse will serve. (2) Tabulate known geothermal resources within region. (3) Rank potential locations in terms of geothermal fluid chemistry and location. (4) Obtain data on chemistry, flow potential, temperature, and probable lifespan of resources. (5) Conduct economic analysis of proposed greenhouse operation using these geothermal sources; compare with optimum fossil fuel economics and long term availability in the region. (6) Proceed with project if economically attractive.

A survey of geothermal process heat applications in Guatemala: An engineering survey  

SciTech Connect

This study investigates how process heat from Guatemala's geothermal energy resources can be developed to reduce Guatemala's costly importation of oil, create new employment by encouraging new industry, and reduce fuel costs for existing industry. This investigation was funded by the US Agency for International Development and carried out jointly by the Guatemalan Government and the Los Alamos National Laboratory. Two sites, Amatitlan and Zunil, are being developed geothermally. Amatitlan is in the better industrial area but Zunil's geothermal development is more advanced. The industry around Zunil is almost exclusively agricultural and the development of an agricultural processing plant (freezing, dehydration, and cold storage) using geothermal heat is recommended. Similar developments throughout the volcanic zones of Guatemala are possible. Later, when the field at Amatitlan has been further developed, an industrial park can be planned. Potential Amatitlan applications are the final stage of salt refining, a thermal power plant, hospital/hotel heating and cooling, steam curing of concrete blocks, production of alcohol from sugar cane, and production of polyethylene from ethanol. Other special developments such as water pumping for the city of Guatemala and the use of moderate-temperature geothermal fluids for localized power production are also possible. 12 refs., 13 figs., 14 tabs.
