A simulator for the geothermal heat pump system considering the groundwater flow has been developed. It is known that the groundwater flow affects the ability of heat extraction such as transient response and recovery of temperature. Therefore, it is necessary to simulate the dynamic behavior of the underground heat extraction system in order to evaluate the heat extraction rate. In this paper, the heat flow in the borehole, U-tube and subsurface layers with groundwater flow have been modeled by using the advective-diffusive equation, and the temporal change of temperature has been calculated based on Finite-Element Method (FEM). We analyzed a thermal response test (TRT) data and have clarified that the tool in this paper can simulate the heat flow in the layers associated with the groundwater flow and also represents the heat exchange between U-tube and layers. It has also been demonstrated that the simulator can examine the relationship between groundwater flow and apparent thermal conductivity, groundwater flow and temperature change of layers with time during heat extraction.
