PURPOSE: A gas engine driving heat pump is provided to reduce costs for a cooling device by cooling engine cooling water to a proper temperature through a heat exchange with a heat exchange media. CONSTITUTION: A gas engine driving heat pump comprises an engine(10), a compressor(20), outdoor and indoor units(30,40), an expansion valve(50), and a four-way valve. The compressor driven by the engine and compresses a refrigerant to high pressure and high temperature. The four-way valve controls a flow direction and leads the refrigerant compressed by the compressor to the outer or indoor unit. Inlet and outlet parts of the outer unit comprise a refrigerant flow path and a cooling water path. The refrigerant flow path is connected to the four-way valve and the expansion valve. The cooling water path guides the flow of cooling water circulated through the engine and cools the cooling water by the heat exchange media.
