Off-Peak Electric Auxiliary Heat for Solar Air-Heating Systems. Final Report, June 1, 1977-December 31, 1978

Description: The performance of various solar auxiliary heating system options is examined by means of computer simulation. Systems which utilize off-peak electrical energy, which is stored in a thermal reservoir for use during the on-peak period, are examined. A storage reservoir which is separate from the solar reservoir is found to be preferable. Performance is generally not found to be sensitive to the time at which off-peak energy is available. Control schemes that predict energy requirements for a for… more

A field study of the effects of inhomogeneities of surface sensible and latent heat fluxes

Description: In recent years, the problem of characterizing turbulent fluxes of heat, momentum, and moisture over inhomogeneous surfaces has received increasing attention. This issue is relevant to the performance of general circulation models (GCMs), in which a single grid element can encompass a variety of surface and topographical features. Although considerable progress has been made in describing the energy balance at a surface partially covered by vegetation, less is known about how to treat adjacent … more

Preliminary requirements for thermal storage subsystems in solar thermal applications

Description: Methodologies for the analysis of value and comparing thermal storage concepts are presented. Value is a measure of worth and is determined by the cost of conventional fuel systems. Value data for thermal storage in large solar thermal electric power applications are presented. Thermal storage concepts must be compared when all are performing the same mission. A method for doing that analysis, called the ranking index, is derived. Necessary data to use the methodology are included.

Experimental Study of the Storage of Thermal Energy in Confined Aquifers. Final Report, July 1, 1977-December 31, 1979

Description: To aid in testing the idea of storing thermal energy in aquifers, a two cycle experiment was performed by Auburn University in which heated water was stored in a confined aquifer and then recovered. During the first cycle, 54,784 m/sup 3/ of water were pumped from a shallow supply aquifer, heated to an average temperature of 55/sup 0/C, and injected into a deeper confined aquifer where the ambient temperature was 20/sup 0/C. After a storage period of 51 days, 55,345 m/sup 3/ of water were produ… more

Description: Feasibility studies of thermochemical energy storage and transport (TEST) are described. Cases studied include a large central receiver heat utility and a small industrial process heat application with distributed parabolic dish solar collectors. TEST does not appear to be generally cost-effective; however, there are special cases of cost-effectiveness. The overall recommendation is that research on thermochemical processes should emphasize the manufacture of renewable fuels using solar energy … more

Description: A new system for year-round collection and storage of solar heated water for heating of buildings has been designed and constructed at the University of Virginia. The system is composed of an energy storage sub-system which stores hot water in an underground pool and of a solar collector sub-system which acts not only to collect solar energy throughout the year but also to limit the evaporative and convective heat losses from the storage system. The annual collection and storage system began op… more

Microwave impregnation of porous materials with thermal energy storage materials

Description: A method for impregnating a porous, non-metallic construction material with a solid phase-change material is described. The phase-change material in finely divided form is spread onto the surface of the porous material, after which the porous material is exposed to microwave energy for a time sufficient to melt the phase-change material. The melted material is spontaneously absorbed into the pores of the porous material. A sealing chemical may also be included with the phase-change material (or… more
