A heat exchanger ((
1) is arranged opposite to the air outlet (1)), and the heat exchanger m! (A plurality of centrifugal blowers (g) each consisting of an impeller (e) and a spiral casing (f) are disposed opposite to (1), and the impeller (e) is extended from the electric motor 11 (11). /j It was generally constructed by fixing two tree axes (j) and (i3).

当たる時の騒音も大きくなるという欠点があった。Therefore, in the conventional configuration described above, the intervals between the centrifugal blowers (4) are uneven, and the electric motor (1+) is located near the suction port (j) of the centrifugal blower (g). Since there are places where there are no centrifugal air blowers (1<), the step-side air resistance of the centrifugal blower 4 clouds (1<) differs depending on each centrifugal blower (g), and the heat exchanger ((I ), the flow rate of the flow flowing out towards the heat exchanger ((1) becomes uneven, making it impossible to blow air efficiently. The disadvantage is that the maximum velocity of the flow toward the heat exchanger (c+) becomes larger than necessary, and the noise when the wind hits the heat exchanger (c+) also becomes large.
