If drain abnormality occurs, for example, an air blower 24a of an indoor unit 2 in which abnormality occurs is stopped, an electronic expansion valve 21a is fully closed, and the temperature of a heat exchanger 23a of the indoor unit 2 in which abnormality occurs is detected by a thermisor 30a. If this temperature increases, the operation of an indoor unit 3 having no drain abnormality is continued, and if this temperature does not increase, the operation of all the indoor units 2 and 3 is stopped. When a compressor 5, which has been stopped by the occurrence of abnormality, is restarted, it is determined whether or not the temperature of the indoor heat exchanger 23a decreases. If this temperature does not decrease, the operation of the other indoor unit 3 is continued, and if this temperature decreases, the operation of all the indoor units 2 and 3 is stopped. <IMAGE> |
