Abstract (en)
An air-conditioning apparatus is disclosed that is provided with an air-sending device that includes: a housing (1); a fan (2) that is disposed in the housing (1); a casing (7) that guides an airflow, the casing (7) arranged adjacent to the back side of the fan (2); and a stabilizer (9) that stabilizes the circular vortex, the stabilizer (9) arranged adjacent to the front side of the fan (2). When ´ = A/D expressed by an air flow inlet port (4) width A and a fan diameter D is 2 or lower, an outer peripheral blade inflow angle ² = ´ × ³ radian is in the range of 0.4 ‰¥ ³ ‰¥ 0.3. The air-conditioning apparatus provided with an air-sending device is capable of suppressing noise as well as increasing fan performance even when the inlet port (4) is narrow.
