Introduced the self-built 10kW geothermal heat pump system test equipment and test instruments, test data processing methods, the effect of winter heating and cooling in summer, summer variable water run test results. The heat transfer model of shallow vertical tube geothermal heat pump system was established by using the energy balance and heat conduction equation combined with the correction coefficient of the tube group. The two-dimensional heat transfer equation was established according to the radial direction and the tube length to calculate the earth temperature Field recovery, and the mathematical model calculated values and measured values were compared
