Abstract

PURPOSE: To simplify the construction of an air conditioner which includes a heat pump type refrigerating cycle comprising as a major means a compressor and to reduce the cost of the air conditioner, by controlling at an indoor unit side the defrosting operation of an outdoor heat exchanger.
CONSTITUTION: When in accordance with the progress of frosting on an indoor heat exchanger 3 the temperature of an outdoor heat exchanger 5 is lowered below a predetermined temperature, that is, when a voltage in a conjunction a becomes lower than a predetermined voltage in a conjunction b through an increas of resistance of a thermistor 20, a logical "1" signal is outputted from a comparator 43. In this case, as a certain time has passed after the start of heating operation, the output of a time safe circuit 47 has already been a logical "1" signal. As a result a defrosting start signal (the logical "1" signal) will be issued from an and circuit 46, and it will be fed into a microcomputer programed with a timer function and a temperature regulating function or the like.
