摘要：

For the cold region with high solar radiation intensity, this paper aims to increase the net power generation of photovoltaic panels, and properly use the waste heat generated by photovoltaic backboards. An indoor ground source heat pump heating system based on waste heat from photovoltaic power is designed. Taking a 100 m2 rural residence is analyzed in Zhangjiakou as the example, an analysis model is established by TRNSYS simulation software. The effects of different cooling flow rates on photovoltaic panel power generation, average temperature of photovoltaic and soil temperature are analyzed and compared. It is concluded that the change of cooling water flow has little effect on soil temperature. The optimal cooling water flow rate of the system is 4700 kg/h. Meanwhile, the annual net power generation of photovoltaic panels has reached a maximum of 5900 kWh and increased by 386.63 kWh compared with the non-photovoltaic cooling system. © 2021, Solar Energy Periodical Office Co., Ltd.
