<p>Intended is to solve a problem which is caused by a residual frost in the outdoor heat exchanger of an air conditioner. In a heating operation after a defrosting operation of the case, in which the operation is switched to the heating by continuing the defrosting operation for a defrosting operation guard time and in which the outdoor heat-exchanging temperature after the lapse of the defrosting operation guard time is not higher than the target heat-exchanging time, the heating-operation guard time is shortened to 0. In the heating operation after the defrosting operation, therefore, the operation switches to the defrosting operation when the outdoor heat-exchanging temperature becomes lower than the defrosting operation starting temperature, even before the heating-operation guard time elapses from the heating-operation starting time.</p> |
