The University of Tennessee-Tennessee Valley Authority Solar Augmented Heat Pump Test Facility is an unoccupied building containing a parallel heat pump/off-peak resistance/solar heating system. The performance of this system has been simulated using a modified version of the TRNSYS solar simulation computer program. Generally accurate results were obtained when simulation results were compared against data collected on-site for the 1979-1980 heating season. Predictive results were also obtained from the model for an entire year of weather data. Performance of the system was compared against: (1), a solar/heat pump system without off-peak resistance heat; (2), a similar system with heat pump only; and (3), a similar system with an off-peak heat pump replacing the resistance heat. The results show that the off-peak systems may not be economically feasible except at large ratios of on-peak to off-peak power rates. The two off-peak systems were also found to be very sensitive to control configuration.
