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

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.

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

Goals study for technical development and economic evaluation of the compound parabolic concentrator concept for solar energy collector applications

Description: The Argonne National Laboratories, contracted with Arthur D. Little, Inc. (ADL), to perform a 6 week goal study for the purpose of evaluating the technical applicability and the economic viability of the compound parabolic concentrator (CPC) concept for all solar energy applications except large central power plants. During this period, we studied the use of CPC units in a large number of residential, industrial, and commercial applications. The predicted performance of CPC augmented solar coll… more

Timonium Elementary School solar energy heating and cooling augmentation experiment. Final engineering report: executive summary (ER-8877)

Description: This report covers a two-year and seven-month solar space heating and cooling experiment conducted at the Timonium Elementary School, Timonium, Maryland. The system was designed to provide a minimum of 50% of the energy required during the heating season and to determine the feasibility of using solar energy to power absorption-type chillers for cooling. The area to be heated or cooled totaled approximately 8500 square feet of the center wing of the school. To accomplish this a system containin… more

Atlantic Coastal Plain. Geothermal energy and the eastern US: a scenario for geothermal energy development

Description: A brief narrative outline is presented of a scenario for the development of the Atlantic Coastal Plain hydrothermal resources for geothermal space heating and cooling. Listed below are the basic assumptions made in the construction of this scenario. Since this scenario is to serve as a planning document, the steps involved in geothermal development are listed and time-phased. The most critical steps in this process are indicated. This scenario summarizes geothermal development in the entire Atl… more

Solar energy system installed at the North Georgia APDC office building

Description: Information is provided on the solar energy system installed in the newly constructed office building of the North Georgia Area Planning and Development Commission near downtown Dalton, Georgia. This solar heating, cooling and hot water system supplies 65 to 70% of the cooling demand and 90 to 95% of the heating demand. There are 2,001 square feet of effective Revere collector area, and the absorption chiller is in Arkla model 300 and provides 16 tons of cooling.

Feedback as a means of decreasing residential energy consumption. Report PU/CES 34

Description: When residential units are analyzed in human factor terms, it is apparent that the consumption level feedback (typically a bill, calculated once a month, over all appliances) is inadequate to give the resident useful information about his energy consuming actions. The present study tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electric usage would be effective in reducing electric consumption. In the studied homes, central air-conditioning … more
