【 摘 要 】

Solar-assisted air source heat pump (SAASHP) has greatly improved the operating efficiency of the system. However, the operational performance of the key modules in the combined system is not clear. So a solar-assisted air source heat pump radiant heating system was established and a SAASHP was monitored. The key parameters of the solar collector outlet water inlet water temperature, and water tank temperature under different combined operation modes were calculated. The solar collector heat collection efficiency, system COP, and the energy consumption ratio under the corresponding mode were given. The solar collector heat collection efficiency, system COP, and the energy consumption ratio under the corresponding mode were given. Photo thermal conversion, evaporative heat transfer, and energy conversion between the condensers. By comparing the operating characteristics of each combination mode, the characteristics of SAASHP combined operation are finally obtained.
