Stirling total energy systems study. Final report, May 15, 1976--June 13, 1977

Description: The application of Stirling cycle prime movers to total energy power generation systems was investigated. Electrical, heating, and cooling demand profiles for a typical residential complex, hospital, and office building were studied, and alternative Stirling total energy systems were conceptualized for each site. These were analyzed in detail and contrasted with purchased-power systems for these sites to determine fuel-energy savings and investment attractiveness. The residential complex and ho… more

Engineering considerations of the advanced free electron laser facility

Description: The Advanced Free-Electron Laser (AFEL) is being built at Los Alamos inside a large laboratory building. In addition to cost and available space considerations, several engineering issues affected the design of the AFEL and its facility. The 1300-MHz, 20-MeV electron linac required extensive radiation shielding and a short rf-waveguide run. Free-Electron Lasers (FEL) and photocathode-drive laser optics required a clean, constant temperature environment. New environmental, health, and safety (ES… more

Form-stable crystalline polymer pellets for thermal energy storage. Phase 1

Description: The objective of this project was to develop a form-stable, crystalline polymer pellet TES bed material, useful in the 120 to 140/sup 0/C temperature range suitable for solar absorption air conditioning applications. This objective was achieved with a Si-O-Si crosslinked HDPE pellet material, demonstrated to have a high heat of fusion value (46 cal/g, approximately 98% of the HDPE's heat of fusion value prior to crosslinking). Further, on melt/freeze cycling of these TES pellets through 400 cyc… more

Studies of evaporative and conventional cooling of an energy conserving California house

Description: For cooling a Sacramento, California home, (1) higher thermostat settings, (2) insulation (3) ''solar control'' window shades, and (4) the use of an evaporative cooler in the place of a vapor compression cycle air conditioner are studied. A computer program TWOZONE is used to evaluate the effect on energy consumption and peak power. It is calculated that the peak cooling load can be reduced by a factor of 5 or more and the total energy by a factor of 20 or more.

Microcomputers for energy conservation in homes and other small buildings

Description: Low cost microcomputers and related microelectric devices now make it practical to apply additional energy conserving control strategies in single-family homes and other small buildings. These conservation measures can make significant contributions toward attainment of national energy conservation objectives. Applications in space conditioning (heating, cooling, ventilation), lighting, electric demand limiting, metering of energy in various forms and for status displays are outlined. Examples … more

Monitoring of the performance of a solar heated and cooled apartment building. Final report

Description: An all-electric apartment building in Texas was retrofitted for solar heating and cooling and hot water. The system consists of an array of 1280 square feet of Northrup concentrating tracking collectors, a 5000-gallon hot water storage vessel, a 500-gallon chilled water storage vessel, a 25-ton Arkla Industries absorption chiller, and a two-pipe hydronic air conditioning system. The solar air conditioning equipment is installed in parallel with the existing conventional electric heating and coo… more

Geothermal energy for American Samoa

Description: The geothermal commercialization potential in American Samoa was investigated. With geothermal energy harnessed in American Samoa, a myriad of possibilities would arise. Existing residential and business consumers would benefit from reduced electricity costs. The tuna canneries, demanding about 76% of the island's process heat requirements, may be able to use process heat from a geothermal source. Potential new industries include health spas, aquaculture, wood products, large domestic and trans… more

Geothermal development of the Madison group aquifer: a case study

Description: A geothermal well has been drilled at the St. Mary's Hospital in Pierre, South Dakota. The well is 2176 feet deep and artesian flows 375 gpm at 106/sup 0/F. The well is producing fluids from the Mississippian Madison Group, a sequence of carbonate rocks deposited over several western states. The project was funded to demonstrate the goethermal potential of this widespread aquifer. This case study describes the development of the project through geology, drilling, stimulation, and testing.

HVAC (heating, ventilation, air conditioning) literature in Japan: A critical review

Description: Japanese businessmen in the heating, ventilation, air conditioning, and refrigeration (HVACandR) industry consider the monitoring of technical and market developments in the United States to be a normal part of their business. In contrast, efforts by US businessmen to monitor Japanese HVAC and R developments are poorly developed. To begin to redress this imbalance, this report establishes the groundwork for a more effective system for use in monitoring Japanese HVAC and R literature. Discussion… more

Preparation of a computer-compatible data base on an operating total energy system. Final report. [Indian Creek Village, Overland Park, Johnson Co. , Kansas]

Description: This report documents the development of a computerized data base on the long-term performance of the Indian Creek Total Energy System, and it is intended to be a user's manual for the data base and the accompanying energy-balance computer program. The data base may be used as a standard of comparison for the performance predicted by energy-system-simulation software. The TES became operational in 1972 to meet the projected electrical, space conditioning, and domestic hot water needs for t… more

Fort Hood solar cogeneration facility conceptual design study

Description: A study is done on the application of a tower-focus solar cogeneration facility at the US Fort Hood Army Base in Killeen, Texas. Solar-heated molten salt is to provide the steam for electricity and for room heating, room cooling, and domestic hot water. The proposed solar cogeneration system is expected to save the equivalent of approximately 10,500 barrels of fuel oil per year and to involve low development risks. The site and existing plant are described, including the climate and plant perfo… more

Preliminary feasibility study of heating and cooling alternatives for Nebraska Western College, Scottsbluff, Nebraska

Description: The existence of a recently-recognized, low-temperature, geothermal resource under central and western Nebraska represents a potential alternate energy source. The feasibility of using that resource for space heating and cooling at Nebraska Western College, Scottsbluff, Nebraska, as an alternative to that facility's current, natural-gas fired, heating and cooling system is explored. This study addresses: (1) the geological (hydrological) aspects of such a project; (2) the retrofitting requireme… more

Commercialization survey for the Department of Energy's Solar Building Demonstration Program

Description: The National Solar Heating and Cooling Program for commercial buildings has been in place for approximately seven years. In the drive to create a viable solar heating and cooling industry in an unprecedented short period of time (5 years), mistakes have been made but many lessons have been learned. The biggest mistake was the belief that the time was ripe for a demonstration program instead of an applications test program. This has led to the following: forcing of the technology before it was f… more

Approaches for Acquiring Energy Savings in Commercial Sector Buildings : Environmental Assessment.

Description: Bonneville has carefully considered the potential environmental impacts associated with installation of currently known Energy- efficient Conservation Measures (ECMs) in new and existing commercial buildings, and has implemented specific requirements to minimize those impacts. These Commercial Environmental Requirements would apply to the three proposed conservation approaches outlined in this environmental assessment. The cumulative energy savings from these proposed commercial programs will h… more
