<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of enhancing rising performance for heating. <P>SOLUTION: A cooling water target temperature TTC is made variable in response to an outside air temperature and an indoor temperature, in a heating operation (step S5), the cooling water target temperature TTC is corrected to a negative side in the condition where a load level of a gas engine is high (steps S6, S7), the cooling water target temperature TTC is set to a forced target temperature higher than a cooling water temperature TC, when the condition where the cooling water temperature TC is a low temperature continues (steps S8-S12), and a motor-driven three-way valve is controlled to increase cooling water for the gas engine flowing in the second route having a refrigerant heating heat exchanger for conducting heat exchange between the cooling water in a cooling water circuit and a refrigerant in a refrigerant circuit, when the cooling water temperature TC is higher than the cooling water target temperature TTC (step S20). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
