CENTRIFUGAL BLOWER

PROBLEM TO BE SOLVED: To provide a double-axis centrifugal multiblade blower for improving a decrease in blowing performance and the deviation of blowing balance in a bi-axial fan in the case of one-side suction and preventing a decrease in cooling performance in an air conditioner without changing the size of the entire blower. SOLUTION: The centrifugal blower comprises a multiblade fan connected to each rotary shaft of the bi-axial motor; each casing for storing each multiblade fan while the inside is composed in a scroll structure; and a cover for covering both the casings. In the centrifugal blower, the cover has an opening only at a part corresponding to the air suction port of one casing other than a part corresponding to an air discharge port from each casing, a part at the side of the air discharge port in the scroll part in one casing is composed in a double-layer scroll structure by a partition board, and partial discharge air separated by the double-layer scroll structure flows out in the cover toward the air suction port of the other casing.
