The mingled system of ground source heat pump with cooling tower has its advantage in winter cold and summer hot region. Basing on the experiments of a ground source heat pump system assisted with cooling tower in Wuhan, the operation controlling strategies of mingled ground source heat pump system were studied in this paper. And the maximal temperature controlling method was adopted by comparing energy cost of the system and soil temperature changes in different cases. The results show that cooling tower could operate as the single cold source instead of buried tubes when the outlet water temperature in buried tube is lower than 32°C. It will help to increase the operation efficiency and decrease the energy cost of this ground source heat pump system. And it will also release heat accumulation problem of the soil surrounding buried tubes.
