空気調和装置。 In a heat pump type air conditioner that defrosts a heat exchanger by causing refrigerant in a refrigeration cycle to flow backward, a first temperature sensor detects the temperature of the indoor heat exchanger and a second temperature sensor detects the temperature of the outdoor heat exchanger. and a temperature at which a significant signal is generated when the temperature of the outdoor heat exchanger is below a predetermined value based on the output signal of the second temperature sensor and this state continues for a predetermined time or more. - time discrimination means, first temperature discrimination means that generates a significant signal when the temperature of the indoor heat exchanger exceeds a predetermined value based on the output signal of the first temperature sensor; a second temperature determination means that generates a significant signal when the temperature of the outdoor heat exchanger exceeds a predetermined value based on the output signal of the temperature sensor; control means for stopping the blower, starting a defrosting operation when the first temperature determining means generates a significant signal, and canceling the defrosting operation when the second temperature determining means generates a significant signal; An air conditioner characterized by:
