<p>A centrifugal blower (1) comprises first and second multiblade fans (5, 6) connected to respective rotary shafts (3, 4) of a double-axis type motor 2, first and second scroll casings (7, 8) containing fans (5, 6), and a cover (9) for covering both casings (7, 8). The cover (9) has an opening (12) only at a position corresponding to a position of an air intake port (11) of first casing (7) except air discharge ports of both casings (7, 8). The reduction of the ability for air sending and the unbalanced air sending of a double-axis type blower maybe improved in a case of one side air intake, without changing the size of the entire blower, and the reduction of the cooling ability of the air conditioning unit may be prevented.</p> |
