<p><P>PROBLEM TO BE SOLVED: To provide an air conditioner capable of suppressing a failure of an engine while operating the engine even if a three-way valve is failed. <P>SOLUTION: In the air conditioner 100, the cooling water is circulated among the engine 2, a radiator 5, and a refrigerant heat-exchanger 6, by a circulation passage and a pump 4. The three-way valve 7 interposed in the circulation passage adjusts the ratio of a cooling water flow rate given to the radiator 5 relative to a cooling water flow rate given to the refrigerant heat-exchanger 6. A controller 11 controls the drive of the valve 7 and the pump 4, and when the valve 7 is failed, such control is conducted that a cooling water temperature is raised while operating the engine 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
