ABSTRACT:
An air conditioner discharges air through an air outlet and into a room. The direction of the discharged air is controlled by adjusting horizontal and/or vertical blades extending across the air outlet. The air flow rate can be controlled by adjusting a variable speed fan. Infrared sensors detect human bodies in the room and determine a distance and direction of the bodies with respect to the air conditioner for controlling the blades and fan in order to supply air to a region(s) of the room in which a human body is detected.
