Abstract:
Provided is an air conditioner in which air blowing noise generated when a discharge air flow strikes fins is reduced without a significant increase in air flow resistance. This air conditioner is provided with: an indoor heat exchanger (18) disposed surrounding the outer periphery of a turbo fan (17); and a plurality of flow conditioning plates (32) mounted on the inner peripheral side of the indoor heat exchanger (18). The indoor heat exchanger (18) has: a plurality of flat surface sections arranged along a flat plane perpendicular to a radial direction at a closest position (P1) which is closest to the turbo fan (17); and a plurality of curved surface sections which connect the plurality of flat surface sections. First flat surface sections (18A) have mounted thereon: a first flow conditioning plate (32A) located at a first predetermined position on the upstream side of the closest position (P1) in the rotational direction (Rd) of the turbo fan (17); and a second flow conditioning plate (32B) located at a second predetermined position on the downstream side of the closest position (P1) in the rotational direction (Rd) of the turbo fan (17), the first and second flow conditioning plates (32A, 32B) being arranged adjacent to each other.
