The use of shallow geothermal energy is based on shallow geothermal energy exploration. The paper presents the application of thermal response test in the shallow geothermal energy project located in Zhengzhou area. The project is tested by a thermal response test rig with two different heat injection rates in two separated boreholes. The two-dimensional model inside borehole and the linear heat source model outside borehole are used as the heat transfer models. The thermal conductivity and heat capacity of soil is calculated by the two-variable parameter estimation (λs andρs cs ). The test results are analyzed.
