PROBLEM TO BE SOLVED: To realize comfortable air conditioning with as lesser energy as possible by periodically controlling a discharge direction of a second nozzle so that conditioning air is discharged toward a moving heat load. SOLUTION: A first nozzle 20 for discharging conditioning air toward substantially the entirety of an air conditioning space 11 and a second nozzle 21 for discharging conditioning air toward a living region 12 of the space 11, are located, respectively, at a plurality of positions in an upper portion of the space 11. The living region 12 in the space 11 is divided into six equal parts with each of them being arranged with the second nozzle 21 at an upper portion thereof. A controller 17 grasps the position and the number of a person 13 who is present at each of the regions by means of a CD camera 15, adjusts the direction of the individual second nozzles 21 in accordance with the grasped information so as to control the discharge direction of the conditioning air, and further controls discharged amount of the conditioning air by means of a motor damper 39'. |
