Abstract
To solve a problem that air-flow resistance of air blown from each corner part of air blowing paths increases, reducing a volume of air, and increasing noises by the air blowing to openings formed at four directions.This ceiling cassette type air conditioner comprises intake ports 1 opened to a bottom face side, blowing ports 2 formed approximately symmetrically around the intake ports, a blower fan 3, a heat exchanger 4 arranged around a centrifugal direction of the blower fan, side walls 5 arranged around the heat exchanger 4, a top face part 6 covering the top face side of the blower fan in contact with the side walls, and a bottom face part 7 constituted to cover the bottom part of the heat exchanger. It is equipped with a partition part 8 standing in a blowing direction adjacent to the side walls 4, and a second partition part communicated with the partition part 8 to form a blow path 9. The air blown from each corner part is not rushing to the openings by the partition part 8, or the blow-out flow of each corner part is blown to the blow-out port 2 by the blow path 9 without resistance.
