HEAT PUMP, SOLAR ENERGY AND ICE STORAGE SYSTEMS – MODELLING AND SEASONAL PERFORMANCE


This paper investigates the seasonal performance of a combined solar, heat pump and ice storage system for residential dwellings. Simulation models for an ice storage and a
solar thermal absorber are presented and compared to test data. A simulation study is performed
for four different heat loads, i.e. building types, ranging from low-energy building to non-renovated existing building. The simulation results show that the solar ice storage system generates heat efficiently for a large variety of heat loads and consistently reaches a seasonal performance factor comparable to heat pump systems with borehole heat exchangers, i.e. SPF ~ 4.
