Abstract
PURPOSE: To unnecessitate a signal line between the indoor unit and the outdoor unit and reduce the cost by judging the temperature of an outdoor heat exchanger by the temperature of the indoor heat exchanger and the temperature of the compressor motor, and controlling the defrosting operation in accordance with the result of the judgement.
CONSTITUTION: When a heating operation is set on an operation control part 10, an air feed motor 7, a square change-over valve 2, an air feed motor 61 and a compressor motor 11 are respectively actuated to start heating operation. During the heating operation, waterdrops adhering to the surface of an outdoor heat exchanger 3 are gradually converted into frosts in accordance with the lowering of the outdoor heat exchanger 3. On this occasion, the temperature of the indoor heat exchanger 5 is detected by the variation of the resistance value of a thermistor 20, and the current flowing through the compressor motor 11 is detected by a current detector 40. In a case where the output of the current detector of the outputs converted into voltages, 40 becomes smaller than the output of the thermistor 20, a defrosting operation starting instruction is produced as output through a main control part 11.
