PURPOSE: A high-efficiency gas engine type heat pump system is provided to improve air intake-charging efficiency of a gas engine by exchanging the heat of underground water and air intake to the gas engine, thereby improving the combustion efficiency of the gas engine. CONSTITUTION: A high-efficiency gas engine type heat pump system comprises a heat pump, a cooling-and-heating water line, an engine cooling water line, an underground water circulation line, an air exhaust heat exchange unit (71), and a defrosting water circulation pump (72). The heat pump includes a compressor (11), a four-way valve (12), an outdoor unit, first to third heat exchangers (14-16), and first to fourth expansion valves (17-20). The compressor is driven by a gas engine and compresses a refrigerant. The first to third heat exchangers exchanges heat respectively with the cooling-and-heating water, the engine cooling water, and the underground water. The first to fourth expansion valves respectively decompresses the refrigerant flowing from the first heat exchanger, the outdoor unit, or the third heat exchanger by a wire drawing effect. The air exhaust heat exchange unit exchanges heat with an exhaust pipe of the gas engine. The defrosting water circulates the air exhaust heat exchange unit and the outdoor unit via a defrosting water circulation line.
