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. In the results, the superiority of the suggested system has been quantitatively evaluated comparing with the conventional heat pump system using one heat source. Furthermore, it was more significant in cold climate, in which the heating COP was 64% up compared the air source heat pump system, than it in subtropical climate, 46% up.
