PROBLEM TO BE SOLVED: To provide an air conditioner having a self-diagnostic function of estimating a failure part by fixing the rotating speed, expansion valve opening, and the like of a compressor and a blower to operate the air conditioner, and comparing it with an ideal operating state in view of a conventional self-diagnostic function that can individually discriminate the quality of specific parts but cannot find the failure of parts not directly connected to a control device. SOLUTION: The failure part is estimated from displacement from an ideal value by integrally grasping the operating state of a refrigerating cycle. The failure part can thereby be specified efficiently in repair. COPYRIGHT: (C)2006,JPO&NCIPI |
