PURPOSE: A hybrid geothermal heat pump system is provided to supplement insufficient heating source through the subterranean heat of a ground heat exchanger and the external air of the air heat pump system. CONSTITUTION: A hybrid geothermal heat pump system comprises a deep well pump device(10), a heating source storage tank(20), a ground heat exchanger(30), an air heat pump system(90), a geothermal heat pump(40), and a load thermal storage tank(50). The deep well pump device transfers the subsurface water through a deep well pipe(12). The heating source storage tank is filled with the subsurface water transferred through the deep well pump device. The heating source storage tank is connected to a heating source storage tank(32) through the subterranean heat circulation pipe and heat-exchanges with the subsurface water and the ground heat exchanger supplements the insufficient heating source. The air heat pump system is connected to the heating source storage tank and heat-exchanges with the external air to supplement the insufficient heating source. The geothermal heat pump connects to the heating source storage tank and exchanges the heat of high and low temperature water and the circulating water heat-exchanged in a load side(1). The load thermal storage tank is filled with the circulating water heat-exchanged through the geothermal heat pump and the circulating water heat-exchanged in the load side.
