Abstract (en)
In an indoor unit, when the fan diameter of a tangential fan (14) is taken to be D, and the width of the intake diaphragm provided on the upstream side of the inlet of an air duct (40) inside the casing is taken to be f, f/D is within the range of 0.002 to 0.003 (0.002 </= f/D </= 0.003). In addition, when the width of the outlet of an air duct (40) formed between the outer peripheral surface (14a) of a tangential fan (14) and the air duct wall surface (41) of the casing is taken to be Wo, Wo/D is 0.55 or less (Wo/D </= 0.55). In addition, when a line extending in the direction of flow along the upper surface that forms the discharge port serving as the air duct outlet in the casing is taken to be a, the stabilizer tongue end angle alpha , which is formed between the surface of the stabilizer opposing tangential fan (14) and the extended line a, is within the range of 50 degrees to 60 degrees (50 degrees </= alpha </=60 degrees). In addition, when the distance between the extended line a and a tangent b of the fan diameter D parallel to said extended line a is taken to be d, d/D is within the range of -0.2 to 0.2 (-0.2 </= d/D </= 0.2). <IMAGE>
