Commercial building unitary heat pump system with solar heating. Final report, May 1, 1976--October 31, 1977
A generalized dynamic computer program (SYRSOL) has been developed for the mathematical simulation of the thermal behavior of multi-zone solar heated buildings. The system modeled employs a series of water-to-air heat pumps connected in a closed loop, flat-plate liquid cooled solar collector, a water storage tank, and a cooling tower. Weather data are represented by sinusoids, which provide a convenient and economical alternative to weather tapes. Results indicate that the use of sinusoidal functions for temperature and monthly average values for cloud cover is quite realistic and accurate. Temperature functions for thirteen cities are presented. A preliminary analysis has been done of the feasibility of using solar-energized desiccant dehumidification systems to reduce summer cooling loads. Service hot water production using a water-to-water heat pump from the storage tank is shown to be highly effective and idle solar collectors can be used directly to make service hot water in the summer. A new mathematical heat pump heating model, in which the COP increases linearly with the source water temperature, has been developed and incorporated into SYRSOL. The computer simulation capability has been extended from a heating season to an entire year. The results of some experiments, that have improved the COP of a heat pump, are also reported.
