According to the present invention, in a heating operation where a heating indoor heat exchanger function as a condenser and an outdoor heat exchanger functions as an evaporator, an air amount supplied by a blower is reduced when a predetermined amount of frost is or may be deposited on the outdoor heat exchanger in an outside air introduction mode where an outside air is supplied into a passenger compartment. Accordingly, a heating load is reduced to thereby reduce an endothermic amount in the outdoor heat exchanger. As a result, a frost deposition speed is reduced, and a deposited frost limit is increased, thereby extending a heating operation period.
