摘要： The length of a cross flow fan in the rotational axis direction is longer than the length of an air outlet in the longitudinal direction, and the cross flow fan has a fan extension positioned beyond each end of the air outlet in the rotational axis direction. Deflectors are provided in the air-conditioning apparatus main body. An outlet airflow blown from each fan extension of the cross flow fan impinges upon a corresponding one of the deflector. Furthermore, the shape of blade portions of the fan extensions of the cross flow fan and the shape of blade portions opposing the air outlet are different from each other. The wind speed of the outlet airflow blown from the blade portion is lower than the wind speed of an outlet airflow blown from the blade portion.

摘要： An impeller element includes a plurality of blades disposed along an outer circumference of a circular support plate. Each blade is divided into a plurality of blade sections in a rotational axis direction. At least one of the divided blade sections as a long-chord blade section is configured such that a chord as a line segment connecting a blade outer-circumferential edge and a blade inner-circumferential edge of the blade in a cross section perpendicular to a rotational axis of the blade has a greater length than a chord of another one of the blade sections as a short-chord blade section. The blade inner-circumferential edge of the at least one long-chord blade section having the longer chord protrudes toward the inner circumferential side, relative to the blade inner-circumferential edge of the at least other one of the blade sections as the short-chord blade section having the shorter chord.

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.
