Gas heat pump type air conditioning device, and combustion device for heating exhaust gas

In order to obtain more enhanced air heating capacity during low outdoor air temperature, a gas heat pump type air conditioning device which circulates refrigerant by a compressing device (11) of which driving source is a gas engine, forms a refrigerating cycle, collects waste heat of exhaust gas exhausted from the gas engine to engine coolant water by an exhaust gas heat exchanging device (34), and heats the refrigerant by the engine coolant water to enhance the heating capacity, the exhaust gas exhausted from the gas engine is heated, and a heating device for increasing amount of thermal energy which can be collected in the exhaust gas heat exchanging device (34) is provided.
