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 (11) having a gas engine driving source and forming a refrigerating cycle by circulating a refrigerant, an engine-coolant-water system (30), a channel change switching device (37), a bypass channel (36) which is provided with the channel change switching device in the engine-coolant-water system (30) downstream of the gas engine, and an engine-coolant-water heating device (40) provided in the bypass channel (36), 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.
