Sustainable development requires the use of renewable energy resources in all technological fields. The cleanest and greenest of all the energy resources is undoubtedly solar energy. The main goal of the designed solar heat pump is the capability to operate with solar energy and also with the surrounding air as an alternative energy source in the case of inadequate solar irradiation. The coefficient of performance (COP) is the quality criterion for all types of heat pumps. The anticipated COP is larger than 10 for the designed solar heat pump, whereas currently commercially available air-water heat pumps have the COP value of approximately 3.
