Design and computer simulation of solar-heat pump systems. [Comparison of in-line, parallel, and dual-source solar heat pumps]

OSTI ID:6892836

An ''in-line'' solar-heat pump heating and cooling system, which uses the solar heated water in storage as its heat source, is designed for installation in a subdivision model home located in Fort Collins, Colorado. The modular simulation program, TRNSYS, developed at the University of Wisconsin-Madison, is used to simulate the system's performance over an entire heating season and to determine the system's sensitivity to several important parameters such as collector size and storage size. The ''in-line'' system's performance is compared to that of a ''parallel'' solar-heat pump system, a dual-source solar-heat pump system, a conventional solar heating system, and a conventional air-to-air heat pump system. The results indicate that the ''parallel'' system's thermal performance is clearly superior to that of the ''in-line'' system and marginally better than that of the dual-source system.
