Abstract
In an air conditioning apparatus of the separate-type, an indoor unit is mounted on a wall of a room. The indoor unit is provided with an infrared ray detection unit which has an infrared ray sensor for sensing infrared rays, a temperature sensor for sensing a temperature in the detection unit, and a slit window for restricting a field of view of the detection unit. The detection unit is horizontally swung with a discharge opening of the indoor unit, from which warm or cold air is discharged, so that the room is swept by the field of view and the air. The room temperature distribution is obtained from the output signal from the detection unit and, the amount of the discharged air directed to the respective areas of the room is adjusted in accordance with the room temperature distribution.
