Abstract

PURPOSE:To reduce air flow resistance by making the diameter of an inlet of a bellmouth shape larger than the inner diameter and smaller than the outer diameter of a centrifugal fan blade and making the rearmost end of the inlet face a cut of the blade. CONSTITUTION:A bellmouthed inlet 5 is formed, to connect to the inside of a scroll casing 4, at a bottom wall portion 1c of a recirculation/fresh air changeover box 1. Here, a cut 13 is formed at the inner diameter portion of an inlet end 8a of a blade 9 constituting a centrifugal fan 8 arranged inside the scroll casing 4. A relationship between an outlet side diameter D5 at an inlet 5 and the outer and inner diameters D9A, D9B is set to D9B<D5<D9A. Further, the rearmost end 5e of the outlet side 5b at the inlet 5 is placed on the downstream side of a plane flush with the inlet end 8a of the centrifugal fan 8 in relation to the flow of air.
