Abstract PROBLEM TO BE SOLVED: To increase a temperature of supply air by opening and closing a damper at a proper timing, and to prevent deterioration of indoor environment, in particular, in a failure of the damper, when the comfort is to be improved by improving dehumidifying performance in a cooling/dehumidifying operation. SOLUTION: The air conditioner comprises: a raw gas introducing portion (for example, opening portion 80) allowing a raw gas such as indoor air and/or outdoor air to reach an indoor air blower 50 without passing through an indoor heat exchanger 40; and the damper 91 opening and closing the raw gas introducing portion 80 under control by a control means in a cooling cycle operation of a refrigerating cycle. The cooling cycle operation is continued even when abnormality occurs in operation of the damper 91, and a rotational frequency of a compressor is lowered preferably. COPYRIGHT: (C)2007,JPO&INPIT
