Abstract
A ceiling-embedded air conditioner includes: a ceiling-embedded casing body that has an air suction path at the center of a lower surface and has an air blowoff path around the air suction path; a turbo fan that is disposed inside the casing body; a heat exchanger that is disposed inside the casing body on an outer peripheral side of the turbo fan; a bell-mouth that guides air sucked from the air suction path toward the inside of the turbo fan; and a rectifier that is provided on a back surface side of the bell-mouth at the air suction path side opposite to an air suction surface of the bell-mouth, the rectifier suppressing swirling airflows generated by part of air blown from the turbo fan swirling along the back surface of the bell-mouth in the same direction as a rotation direction of the turbo fan.
