Control of direction and flow rate of air delivered by air conditioner - using infrared sensors to measure distance and angle of person in room relative to air conditioner and adjusts circulation and angle of control vanes in outlet

摘要

Procedures and equipment to control the direction and flow rate of air discharged from an air conditioner.An air conditioner discharges air through an air outlet into an enclosure. The direction of the air discharged 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 the presence of human bodies in an enclosure and determine the distance and direction of the bodies with respect to the air conditioner in order to control the blades and the fan for the purpose of supplying air to the region or regions of the enclosure in which a human body is detected.
