Abstract

Occurrence of dew condensation on a design surface side of a louver (7) is inhibited even when an outlet air flow (12c) is blown in a substantially horizontal direction.
An indoor unit (1) of an air-conditioner is provided with a casing (10), a decorative air panel (1b) provided on a bottom surface of the casing (10), a blower (8) and a heat exchanger (3) provided within the casing (10), an air inlet (2) for drawing an indoor air flow into the casing (10), an air outlet (4) for blowing an air flow into a room, and a louver (7) provided on the air outlet (4) for adjusting a wind direction of the outlet air flow (12c). The louver (7) having a cross-sectional shape formed of circular arcs (30, 31) with two or more curvature radii (R1, R2) is formed such that louver shape B/A is in a range of "B/A = 2 to 4" when an angle (A) between a tangent (32) at a louver tip end (7a) of the circular arc (30) forming a front side portion of the louver (7) and a level line (34) is set to A and an angle (B) between a tangent (33) at a louver rear end (7b) of the circular arc (31) forming a rear side portion of the louver (7) and the level line (34) is set to B in a fully-closed state of the louver (7).
