ABSTRACT:
An air conditioner apparatus wherein the range of fluctuation of the difference between the room temperature and the desired preset temperature is divided into a plurality of zones, a variable capacity compressor being driven at frequencies respectively corresponding to these zones, and a heater is provided in an internal unit when a drying operation mode is selected and the room temperature is in a zone lower than the desired preset temperatures. The apparatus is further equipped with a switch that shifts the frequencies corresponding to the zones in the drying operation mode in the direction of an increasing dehumidification capacity.
