<P>PROBLEM TO BE SOLVED: To provide an air conditioner which achieves utilization of hot water supply without losing a heating capacity during a heating operation. <P>SOLUTION: At a circuit 41 for cooling a gas engine, a hot water heat exchanger 52 for increasing the temperature of a use water by exchanging heat with a cooling water is provided in parallel to an exhaust heat recovery heat exchanger 48 that exchanges heat between the cooling water and a refrigerant, and a determining section 62 that determines whether or not the exhaust heat recovery of the refrigerant in the exhaust heat recovery heat exchanger 48 is sufficient based on a state of the heating operation, is provided, and, when this exhaust heat recovery is determined to be sufficient, at least part of the cooling water is controlled to be flown to the hot water heat exchanger 52. <P>COPYRIGHT: (C)2012,JPO&INPIT |
