Document Type and Number:
Japanese Patent JP6379633
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an engine-driven type air conditioner which can be configured at low cost, and can sufficiently recover engine exhaust heat.SOLUTION: An engine-driven type air conditioner 1 includes: a flow passage changeover valve 45 for switching a flow passage of cooling water flowing through a cooling water circuit 40 so that the cooling water which was used to cool a gas engine 10 flows through a flow passage running into the gas engine 10 via an engine exhaust-heat heat exchanger 27 when a cooling water temperature Tw is equal to or lower than a first temperature T1 and the cooling water which was used to cool the gas engine 10 flows through a flow passage running into the gas engine 10 via a radiator 47 when the cooling water temperature Tw is equal to or higher than the first temperature T1; and a control device for controlling an opening of a refrigerant flow adjustment valve 31 or the number of revolutions of a cooling water pump 46 on the basis of the cooling water temperature Tw so that the cooling water temperature Tw becomes closer to an optimum cooling water temperature Topt lower than the first temperature T1.
