PURPOSE:To prevent any short cycle and improve the cooling and heating efficiency by a method wherein a suction device having a multi-vane blower for circulating interior air and a blowing device having a heat exchanger for performing a heat exchanging operation are separated from each other or connected by a duct. CONSTITUTION:Interior air is sucked through a suction ornamental grill 10a by a multi-vane blower 5 within a suction device 1a, passes through blowing ports 5a1 and 5a2 and further the air is blown into blowing devices 1b and 1c through ducts 13a and 13b. Air blown into the blowing devices 1b and 1c performs heat exchanging operation at a heat exchanger 4 and the air is blown into a room along an inclined direction of a louver 9 of a blowing ornamental grill 9a. The blown interior air cools or heats an interior part of the room, the air is sucked again through the suction ornamental grill 10a into the suction device 1a. Additionally, the air passing through the ducts 13a and 13b is only interior suction air, so that there is no possibility that the duct 13 forms a dew formation and a heat insulating work for the duct 13 is not required. |
