To enhance system stability, solar collectors have been integrated with air-source heat pumps. This integration  facilitates the concurrent utilization of solar and air as energy sources for the system, leading to an improvement in  the system's heat generation coefficient, overall efficiency, and stability. In this study, we focus on a residential  building located in Lhasa as the target for heating purposes. Initially, we simulate and analyze a solar-air source heat  pump combined heating system. Subsequently, while ensuring the system meets user requirements, we examine the  influence of solar collector installation angles and collector area on the performance of the solar-air source heat  pump dual heating system. Through this analysis, we determine the optimal installation angle and collector area to optimize system performance.
