Prototype Energy Retrieval and Solar (PERS) System : Final Report.
Technical Report

OSTI ID:6245299
The PERS System, which provides both heating and cooling for the substation Control House, has several different modes of operation. During the winter, heat from the transformer is recovered by a heat pump and is transferred to water circulating through a fan coil unit in the Control House forced air system. In addition, banks of tubular collectors mounted on the roof of the Control House can provide direct solar heating. During the summer, the solar collector array is used to drive a 15-ton absorption air conditioner which cools water in a 4300-gallon storage tank. Mechanical difficulaties were encountered, performance of components was not always satisfactory, and a need for modifications in the system emerged. During the winter testing period in December 1978, the heat recovery system performed with an average Coefficient of Performance (COP) of 2.75, as compared to the design goal of 4.6. The absorption chiller, however, performed quite well during the summer testing period in August, 1978. The coefficient of performance ranged from 0.598 to 0.622 on a daily basis, comparing favorably with the anticipated goal of a COP of 0.74. The overall solar-assisted absorption chiller system performed with a COP ranging from 2.80 to 3.57, with the absorption chiller functioning at even relatively low collector temperatures.
