Abstract (en)

[origin: WO9740326A1] When the drainage fails, for example, a blower (24a) of a faulty side indoor unit (2) is stopped to fully close an electronic expansion valve (21a), and the temperature of a faulty side heat exchanger (23a) is detected by a thermistor (30a). When this temperature has increased, the operation of an indoor unit (3) in which a drainage failure does not occur is contained, and when the temperature has not increased, the operations of all the indoor units (2, 3) are stopped. When a compressor (5) which stopped when the drainage failure occurred is restarted, the faulty side heat exchanger (23a) is judged as to whether the temperature thereof has decreased or not. When this temperature has not decreased, the operation of the other indoor unit (3) is continued, and, when the temperature has decreased, the operations of all the indoor units (2, 3) are stopped.
