Abstract

PURPOSE: To realize a comfortable air conditioning by a method wherein when one of outdoor devices is operating a defrosting operation, a higher frequency is outputted to one in which a defrosting operation of its frequency converter is not carried out as a higher difference is found between a set temperature and a detected temperature.
CONSTITUTION: A defrost controller for an air-conditioner outputs immediately a higher frequency as a higher temperature difference between a set temperature of a temperature setting device 10 and a sensed temperature of a room temperature sensor 9 is found in response to a temperature difference in which the detected temperature is subtracted from the set temperature, to one of the first frequency convertor 4 and the second frequency convertor 7 in which a defrosting operation is not carried out in such a way as an air conditioning controller 12 controls not to decrease a room temperature. Due to this fact, it does not take much time to increase a room temperature decreased by the defrosting operation of one of the two outdoor devices 1 and 2 up to a set temperature under a heating operation of the remaining outdoor device.
