Abstract：The development and utilization of shallow geothermal energy through shallow heat pump technology can meet the heating and cooling demands of buildings in winter and summer.Based on the ground source heat pump project in an industrial plant area in northern Jiangsu Province,shallow thermal response tests are carried out,and the thermal response tests are conducted through double U-shaped ground heat exchangers.The results show that the comprehensive thermal conductivity of the rock and soil mass is(1.80±0.11)W/(m·K),the initial ground temperature is 18.5℃,the heat transfer per meter in summer is 57～60 W/m,and in winter it is 38～40 W/m.The thermal response test methods and related result data adopted in this study can provide references for the design of shallow ground source heat pump systems and the implementation of projects in northern Jiangsu.
