摘要：
The mathematical model of direct expansion solar assisted heat pump system based on photovoltaic/thermal (PV/T) panel has been constructed and the parameter analysis have been conducted. The PV is coupled with evaporator to form a direct-expansion PV/T module, which reduces the PV cells' temperature and improves the overall efficiency while increasing the evaporating pressure and temperature. The system [COP] increases with the increase of PV/T area, solar radiation, and ambient temperature. The system COP can reach 5.79 when the solar radiation intensity is 600 W/m2, and the electrical, thermal and overall efficiencies is 17.77%, 55.76% and 75.49%, respectively. Moreover, the PV panel can meet the power demand of the system while providing 21.4% electricity to the power grid. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
