PURPOSE: To prevent noise from generating without extremely increasing the number of revolutions, and make it possible to perform a comfortable air-conditioning by a method wherein two blowers are provided when blow-out air volume is controlled in response to indoor load.
CONSTITUTION: In the vicinity of a left side blow-out port 7, right side blow-out port 8, and a blow-out port for human body 17, a blower for left side load 12, blower for right side load 13 and blower for human body 18 are respectively provided. At respective blow-out ports, air direction controllable air direction control blade rows 14, 15, 19 are provided. At the time of rising-up for air-conditioning operation, or direct blowing to a human body right after entering the room, the temperature, location or activity quantity of the human body are sensed by a sensor for human body 20, an estimated air velocity by amenity index such as PMV, etc., is realized. For blowing from a device main body 1, direct blowing to a human body is appropriately avoided, and air blowing is faced to the wall by the left side and right side blowing airblowers 12, 13 and air direction control blade rows for left side and right side 14, 15. As the result, temperatures of the side wall or interior of the room can be made closer to a set value, and amenity space can be expanded to the whole of the room by utilizing radiation.
