PROBLEM TO BE SOLVED: To provide an index for facilitating the execution of a design for optimizing the shape, particularly a stabilizer shape in a blowing system formed in an indoor unit, and improve the aerodynamic performance. SOLUTION: When a prolonged line produced in the airflow direction along the discharge-port upper surface 45 of an outlet 43 in an air duct 40 in the casing, is defined as (a), the diameter of a tangential fan 14 is defined as D, and an angle between a surface 51 of a stabilizer 50 opposed to the tangential fan 14 and the prolonged line (a), that is, a stabilizer bladal angle is defined as α, the angle α is set in the range of 50 deg.-60 deg. (50 deg.<=α<=60 deg.). |
