PROBLEM TO BE SOLVED: To suppress supply of cold air during heating operation. SOLUTION: When a temperature air volume control part (62) starts operation, after an indoor fan (32) is driven with the preset lowermost number of revolutions, the refrigerant temperature of an indoor heat exchanger (31) is increased to a value higher than a given value, and when a temperature difference between the refrigerant temperature of the indoor heat exchanger (31) and the indoor temperature is increased to a value higher than a given value, the number of revolutions of the indoor fan (32) is increased to the intermediate number of revolutions higher than the lowermost number of revolutions. A time air volume control part (63) increases stepwise the number of revolutions of the indoor fan (32) to the set number of revolutions with a lapse of a time when the indoor fan (32) is driven at the intermediate number of revolutions.
