However, a single energy system has certain limitations. This paper introduces two composite energy systems in the field of building heating. The existing problems and research perspectives of solar air source heat pump systems and solar ground source heat pump systems are discussed, including the refrigerant overheating problem of the direct expansion solar air source system. The solar energy utilization of the water tank type solar air source system, the feasibility study of the solar ground source heat pump system, the optimization of the collector area and the research on the system operation method. The composite energy system can effectively solve the problems existing in a single renewable energy system and improve the stability and flexibility of the system.
