摘要：
How to solve underground soil thermal balance problem is important for ground source heat pump system. Basing on the experiments of a ground source heat pump system with horizontal spiral pipes in Wuhan, the operation controlling strategies of intermittent operation and continuous operation in this system were studied in this paper. The temperatures of inlet and outlet water in the underground heat exchanger, and soil temperatues around the buried pipe were tested. And these temperaure changes in the intermittent operation and continuous operation are compared and analyzed. The results show that soil temperatures around the buried pipe will recover quickly in the testing intervals of intermittent operation. Intermittent operation has advantages over continuous operation for this ground source heat pump system. It provided the designers of ground source heat pump system with beneficial information about underground soil heat accumulation.
