Abstract：In order to improve the heating efficiency and quality of the urban end heat exchange station,a heat exchange station in Jinan was selected as the research object,and a system operation scheme of PV/T coupled ground source heat pump supplying water and reheating heat to the secondary network of the heat exchange station was proposed.Trnsys software was used to establish a system simulation model of the system scheme,and based on the local weather and relevant data of the heat exchange station in the heating season,the system operation simulation of the simulation model was carried out.The results show that the PV/T photoelectric conversion efficiency is high,the highest is 17.8%.After 20 years of simulation operation,the soil minimum temperature showed a decreasing trend year by year,and the lowest temperature was 13.49℃.The system has a good effect of supplying water to the secondary network,and can increase the water supply temperature by 10.2℃.The system has a high COP value in the heating season,up to 4.86.
