Abstract：
Presents the thermal response test of the ground-source heat pump project. On this basis, develops the research on control strategies. Simulates year-round operating conditions of the three strategies of the ground heat exchanger in priority, cooling tower in priority and optimization control. The research indicates that by using the optimization control strategy, the soil temperature increases 0.28 ℃ at the end of one year operation, the maximum temperature of heat charging in summer is 32 ℃ and the minimum temperature of heat discharging in winter is 8 ℃, meeting the design requirements.
