Ground source heat pump system (GHE) is higher coefficient of system performance than conventional heat source system. For the high performance of the GSHP system, It is necessary to analyze the ground heat exchanger (GHE). However GHE depends on various design factor such as double U-tube diameter, grout thermal conductivity and shank space, Therefore, In this research GLHE-Pro was calculated the thermal resistance of the borehole and the length of required heat exchanger. As the result, it was confirmed that the influence of design factors for GHE.
