摘要：
In order to enhance air heating capacity during low outdoor air temperature, a gas heat pump type air conditioning device comprises a compression device having a gas engine driving source and forming a refrigerating cycle by circulating a refrigerant, an engine-coolant-water system, a channel change switching device, a bypass channel which is provided with the channel change switching device in the engine-coolant-water system downstream of the gas engine, and an engine-coolant-water heating device provided in the bypass channel, and waste heat exhausted from the gas engine is collected in the engine-coolant-water, and the refrigerant is heated by the engine-coolant-water so as to enhance air-heating-capacity.
