PROBLEM TO BE SOLVED: To provide an index for facilitating the execution of a design for optimizing the figuration of air inflow and discharge in a blowing system formed in an indoor unit, and improving the aerodynamic performance. SOLUTION: If the diameter of a tangential fan 14 is taken as D, and the discharge port width of an air duct 40 formed between the outer circumstantial face 14a of the fan 14 and an air duct wall surface 41 of the casing is taken as Wo, then Wo/D is set to be 0.55 or below (Wo/D<=0.55). |
