Heat pump system with uncovered and free ventilated covered collectors in combination with a small ice storage
In the past years research and development for heat pumps in combination with solar thermal collectors increased. In this work it is analyzed how low solar irradiation and ambient air can be used as heat sources. Three different systems were modelled and simulated in TRNSYS. The simulation results show that unglazed collectors and a brine heat pump in combination with a 400 liter ice storage can reach a better performance than a reference system (air source heat pump with covered collectors).
