PURPOSE: To contrive the capacity control with the excellent quick heating property by controlling so that the product of the detected blow-out air temperature and the capacity of the air to be fed by a blower may approach the predetermined maximum value, which is previously set, at the time of quickly heating operation. CONSTITUTION: When an air conditioner switch is turned on, a blower 8 is operated at a low capacity. Next, a difference obtained by subtracting a product A of the blow-out air temperature Ta detected by a temperature detecting sensor 55 and the capacity Ga, which is detected by detecting the input voltage to the blower 8, from the previously obtained maximum value Amax is judged whether it is larger than the predetermined small valueδor not. In the case of YES, the capacity Ga is controlled so that the value of the product A approaches the maximum value Amax . Namely, the revolution number of a motor M for driving the blower 8 is increased by an auto amplifier 51. The trouble that the cycle balance is lost and the temperature and the pressure of the high- pressure side are remarkably lowered is thereby avoided, and while the capacity control with the excellent quick heating property is enabled.
