Abstract:
A ceiling embedded type indoor unit comprising:a casing embedded in a ceiling; a heat exchanger placed within said casing; a plurality of blowers arranged side by side in a longitudinal direction of the casing for blowing air to said heat exchanger; a plurality of motors each fixed to a ceiling side of the casing at upper end thereof and having a rotary shaft, said blowers being mounted at lower ends of the rotary shafts; and a decorative panel mounted to a lower surface of the casing and having two air outlet ports elongated in the longitudinal direction of the casing and parallel to each other and an air suction port formed between said air outlet ports, wherein the heat exchanger comprises C-shaped heat exchangers which surround most of peripheries of the blowers, and wherein a rectifying plate which protrudes inwardly from an inner peripheral surface of said heat exchanger so as to correspond to at least a height of an outlet of said impeller is provided in a downstream side of the air flow discharged from said impeller at a position at which the inner peripheral surface of said heat exchanger and an outer peripheral surface of said impeller are in the closest vicinity to each other.
