ABSTRACT:
A drive control apparatus for controlling the operation of an air conditioner comprises a 24-hour air-conditioning mode, a selector for selecting one of drive and release positions of the 24-hour air-conditioning mode, a load-responsive air-conditioning mode under which the air conditioner is operated in dependence on a load in a space to be air-conditioned, a drive control for effecting one of drive and stop controls of the load-responsive air-conditioning mode, and a preferential output unit for outputting a signal from the drive control in preference to an output signal from the selector. An output from the preferential output unit may be used to drive the operating frequency of the compressor at a predetermined number of revolution, to drive an indoor fan either continuously or intermittently at a predetermined number of revolution, and/or to deflect a vertical deflector blade to a predetermined position.
