Simulation of Combined Solar Thermal, Heat Pump, Ice Storage and Waste Water Heat Recovery Systems. Design Criteria and Parametric Studies
The combination of solar thermal systems with heat pumps, ice storage and waste water heat recovery is analysed by means of transient system simulations. Simulations presented here show that uncovered collectors perform better than covered collectors except for large sized systems where auxiliary electrical back-up is not necessary. Waste water heat recovery systems are found to significantly increase the system performance.
