Gas heat pump type air conditioner, engine cooling water heating device, and operation method of gas heat pump type air conditioner

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.
