PROBLEM TO BE SOLVED: To prevent an increase of noise upon shunting, and an increase of noise and a decrease of an air volume when the volume of fan air is deflected to one air circulation passage by vertically providing a partition plate in opposition to a suction hole, and forming two air circulation passages extending from the suction hole to a blowoff outlet, and setting a predetermined interval between the tip end of the partition plate and the suction hole. SOLUTION: Two air circulation passages are formed between a suction hole 3 in a body casing 1 and blowoff outlets 4a, 4b provided on the opposite sides of the suction hole with the aid of a partition plate 10 vertically provided from the center of a top plate 7 of the body casing 1. Herein, there are horizontally symmetrically disposed indoor heat exchangers 5a, 5b and fans 6a, 6b on the two air circulation passages. When there are assumed that the height from the suction hole 3 to the top plate 7 is H and the height of the partition plate 10 is (h), these variables satisfy the relation: 0.5H<=h<=0.8H, and further when an interval 11 between the tip end of the partition plate 10 and the suction hole 3 is assumed to be (d), (d) satisfies the relation: 0.2H<=d<=0.5H. |
