摘要： A cross flow fan achieves low power input and low noise level by preventing flow separation on an air inlet side and reducing a maximum air velocity in the gap between the blades. At least one of units constituting a cross flow fan is an appearance unit configured such that when the unit is sequentially cut in a direction from one of rings to the other ring along a plane whose normal coincides with a rotation axis, a region S and a region C appear, the radius of a second circle, serving as an inner circumferencial circle (having a radius), in the region S being a first radius of predetermined length, the radius of the second circle, serving as the inner circumferencial circle, in the region C being a second radius shorter than the first radius.

摘要： In an air conditioner, reverse inhalation is prevented while broad band noise and wind sound are reduced. A projection arranged at the leading end of a stabilizer on the downstream side of an air stream flowing along a surface of the stabilizer opposing an impeller and protrudes toward the impeller to define the shortest distance to the impeller. A plurality of grooves or projections are provided on the opposing surface on the upstream side of the projection to disturb the air stream flowing along the opposing surface. The positions of the grooves or the projections are arranged apart in a rotational axis direction. A plurality of convex portions are provided to disturb an air stream flowing along a surface of a casing opposing the impellers. The positions of the convex portions are arranged apart in the rotational axis direction of the impeller.
