Abstract
When the temperatures of outdoor heat exchangersanddetected by outdoor heat exchanger temperature sensorsandbecome equal to or higher than 5 degrees C. and the sucking superheating degrees of compressorsandbecome equal to or lower than 0 degrees C. while an air conditioning apparatusis performing the reverse defrosting operation, the reverse defrosting operation is stopped and the heating dominant operation is resumed. At this time, the total operating times of the compressorsandare reset. The sucking superheating degrees of the compressorsandare obtained by subtracting the low pressure saturation temperatures calculated from the sucking pressures of the compressorsand, from the temperatures of the refrigerants sucked into the compressorsandwhich temperatures are detected by the sucking temperature sensorsand
