In this research, a heat pump system with a heat source network is suggested which utilizes outdoor air heat, solar heat and ground heat as heat source for cooling, heating, hot water and refrigerating. This paper describes the summary of the suggested system and the results of the annual energy simulation. The heating and cooling loads, the electric consumption and the COP were calculated by TRNSYS 16 and evaluated in the cases of different local conditions and different system compositions.

The groundwater heat pump (GWHP) system is an open-loop system that draws water from a well orsurface water, passes it through a heat exchanger and discharges the water into an injection well ornearby river. By utilizing the relatively stable temperature of groundwater, this system can achieve ahigher coefficient of performance and offers a more energy-saving solution than the conventionalair-source heat pump (ASHP) system. On the other hand, its performance significantly depends on thecharacteristics of the groundwater and the underground thermal properties.
