摘要：

This paper optimizes a solar and air source heat pump combined heating system. A simulation model is established by TRNSYS software, which is solved coupling with subsystems. Then, we perform a parametric study on the operation of the system under annual running condition, by which feed-water strategy, solar collector area and water tank volume ratio are analyzed. The results show that the system has the optimal solutions, when only feeding water once at morning, restricting solar collector area to 344 m2, and selecting the volume ratio of the heat storage tank to the constant temperature water tank as 1.5; After optimization, the system energy conservation increases by 11.9%. © 2020, Editorial Board of Acta Energiae Solaris Sinica.
