ABSTRACT:
An air conditioner capable of enhancing responsivity of a blowout temperature of conditioned air while preventing occurrence of an overshoot or undershoot condition of the blowout temperature when a user gives an instruction to change the blowout temperature in a dehumidifying operation mode. In a control state, if a set temperature level is adjusted to increase a blowout temperature of conditioned air by increasing the target condenser outlet temperature, the rotating speed of the refrigerant compressor is increased, while the restriction opening of the heating expansion valve is maintained. Thus, the condenser outlet temperature is regulated to the target temperature with minimal undershoot or overshoot of the target temperature.
