This book was released on 2005 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of potential cost and energy savings, military decision-makers may want to consider the use of energy-efficient heating, ventilating, and air-conditioning (HVAC) systems at their installations. Ground source heat pumps (GSHPs), in particular, show great promise because of their low energy requirements and low life-cycle costs. However, there currently exists no design guidance or established criteria for HVAC selection. Consequently, military decision-makers have no basis for comparing conventional HVAC systems and GSHPs. The Value-Focused Thinking (VFT) methodology was used to create a multi-objective decision analysis model that measures the value of different HVAC systems. Consisting of five bottom-tier values and twelve measures, the model captures the Air Force's objectives regarding its selection of HVAC systems. Using data collected from three different Air Force bases, the model was used to evaluate four HVAC alternatives (three conventional and one GSHP alternative) at each location. Sensitivity analysis was also conducted to provide additional insight into the HVAC selection process. The results of this research indicate that GSHPs are a viable option and should be considered at military installations. Further, the results prove that the VFT model can be an effective decision analysis tool for HVAC selection.

Available in PDF, EPUB and Kindle. Book excerpt: The Civil Engineer Corps and the Naval Facilities Engineering Command has the distinct honor and challenge to oversee all facilities management functions from design and contract, to construction, to maintenance and repair and finally to demolition and disposal. In order to assist this monumental undertaking, the Naval Facilities Engineering Command (NAVFAC) is organized with Engineering Field Divisions (EFD) and Engineering Field Activities (EFA) serving distinct geographic regions of responsibility. As Navy shore facilities continue to age, with average building ages on some stations exceeding 40 to 50 years, maintenance and upkeep costs continue to amass in the midst of military "right sizing" and budget reallocations. As downsizing or "right sizing" continues, the DON will continue to seek a fair balance between operational/war fighting priorities and facilities maintenance and construction initiatives. Money will likely continue to follow ongoing trends and move from facilities Operation and Maintenance (O & M) budgets to the war fighting initiatives such as ships, weapons, aircraft, and research and development of new "Over the Horizon" weapons to further augment our "From the Sea" war fighting strategy. This will continue to place increased pressure of limited O & M budgets upon facilities managers that are responsible for the maintenance and upkeep of all shore support facilities. The ability to do more with less and to stretch the ever shrinking facilities O & M budgets will be key to the success of the Civil Engineer Corps in the years ahead. Geothermal technologies have been utilized in the recent years at eleven Navy and Marine Corp installations. The success of these geothermal system implementations merits further detailed review of the system technology and its benefits.

This book was released on 2013 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work reviews and analyses design options used to assess the feasibility of a Ground Source Heat Pump (GSHP) to supply heating to twelve flats. Incentives for communal heating and renewable energy are examined, as are grants and schemes provided to assist uptake of GSHP systems. Four elements of GSHP system design are evaluated: heating load, pump size, borehole array and heat delivery system. The aim is to determine optimal design by minimising energy demand, land use, material use and project costs, whilst maximising system efficiency. Peak Load calculations and various borehole options are analysed using software simulations. Energy demand is evaluated for pumps and heating delivery systems using calculated methods, and literature review. Minimising materials and equipment, whilst maximising system efficiency is analysed by comparing design options.

Book excerpt: "The NRECA/EPRI End-Use Technology Assessment Project (EUTAP) is a residential load metering project designed to develop load profiles and transferable models for end uses important to electric cooperatives around the country. The EUTAP consists of two independent end-use monitoring studies: (1) the Ground Source Heat Pump (GSHP) Study, undertaken with the cooperation of the East Kentucky Power Cooperative and Buckeye Power; and (2) the Good Cents Homes Study, undertaken with the cooperation of the Alabama Electric Cooperative. The objective of the first study is to develop a model of usage patterns for the emerging technology of ground source heat pumps. The second EUTAP study has as its objective investigation of the properties of "Good Cents Homes." The Good Cents Homes Program has been an important demand-side program for many cooperatives. This report presents results of analyses in both studies. The results include end-use load profiles for space conditioning and water heating, and estimates of the energy and peak savings from Good Cents Homes. A transferable GSHP model developed as part of the EUTAP is also described."
Download or read book Testing and Analysis of a Ground Source Heat Pump in Interior Alaska written by Robbin Garber-Slaght and published by . This book was released on 2019 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground source heat pumps (GSHPs) can be an efficient heating and cooling system in much of the world. However, their ability to work in extreme cold climates is not well studied. In a heating-dominated cold climate, the heat extracted from the soil is not actively replaced in the summer because there is very little space cooling. A ground source heat pump was installed at the Cold Climate Housing Research Center (CCHRC) in Fairbanks, Alaska with the intent to collect data on its performance and effects on the soil for at least ten years. Analysis shows GSHPs are viable in the Fairbanks climate; however, their performance may degrade over time. According to two previous finite element models, the CCHRC heat pump seems to reach equilibrium in the soil at a COP of about 2.5 in five to seven years. Data from the first four heating seasons of the ground source heat pump at CCHRC is evaluated. The efficiency of the heat pump degraded from an average coefficient of performance (COP) of 3.7 to a mediocre 2.8 over the first four heating seasons. Nanofluids are potential heat transfer fluids that could be used to enhance the heat transfer in the ground heat exchanger. Improved heat transfer could lower installation costs by making the ground heat exchanger smaller. A theoretical analysis of adding nanoparticles to the fluid in the ground heat exchanger is conducted. Two nanofluids are evaluated to verify improved heat transfer and potential performance of the heat pump system. Data from the CCHRC heat pump system has also been used to analyze a 2-dimensional finite element model of the system's interaction with the soil. A model based on the first four years of data is developed using Temp/W software evaluates the ground heat exchanger for a thirty-year period. This model finds that the ground heat exchanger does not lower the ground temperature in the long term.

Download or read book The Economics of Heat Pump Systems written by Cary Jonathon Lane and published by . This book was released on 2005 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heat pump systems are becoming a popular choice for residential heating and cooling across the United States. Heat pumps are among the cleanest and best energy- and cost-efficient heating and cooling systems available today. However, cost is a prime motivator when choosing among residential heating and cooling systems and it is therefore desirable to analyze the costs associated with heat pump system operation. This research provides a method of direct comparison between the economics of air-source and ground-source heat pump system operation. The objective is to provide a cost comparison with respect to climate locations across the United States, since heat pump performance is heavily influenced by operating environmental conditions such as the ambient air temperature. A purely analytical approach is used for the comparison, avoiding the complexities and costs associated with surveys or experiments, and obtaining actual utility information. Heat pump systems are briefly surveyed, and the thermodynamic operation of vapor compression refrigeration cycles is examined. Analytic models are developed to simulate heating and cooling operation of dual-mode air- and ground-source heat pumps based upon readily available climate data. Finally, a cost ratio relationship is developed to directly compare the associated operating costs for air- and ground-source heat pump systems for a 31 city sample covering much of the continental United States. The annual cost ratio provides the opportunity to evaluate potential cost savings for the operation of air- or ground-source heat pump installations.
