This article introduced the research on the performance of ground source heat pump system in winter. It analysed the changing pattern of the soil temperature and the COP of heat pump system when the system has a long-term continuous operation and when it jointly operated with the auxiliary solar heat system. The experiment data shows that the ground source heat pump system can raise the outlet water temperature of condenser and indoor temperature after it jointly operated with the auxiliary solar heat system.It is advantageous to raise its heating load, so it can increase heating area effectively. The article summarized the universal operation pattern of the ground source heat pump system in this area.
