Abstract
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.
