ABSTRACT:
Disclosed is a wind direction control method for an airconditioner which effectively controls a wind direction of discharge air according to a position of the air-conditioner. In the air-conditioner which divides the room into a plurality of zones and has a human body sensor for sensing a human body position in each divided zone, the present invention senses whether a human body is present in each zone by using the plurality of human body sensors, calculates a time ratio every zone according to the human body presence time, compares the time ratio with first and second proportional constants, varies a driving range of a louver according to a compared result, and controls a wind direction of the discharge air. A wind direction control method for an air-conditioner varies a wind direction of a discharge air according to a human body existence time ratio in each zones, prevents a deterioration of the air-conditioning performance and a power-consumption due to cool air's discharge towards an empty space, thereby performing an effective air-conditioning operation.
