Abstract

A sirocco fan providing a predetermined airflow rate at a reduced noise level and rotational speed, and an air conditioner having the sirocco fan. The sirocco fan satisfies the relationships of 0.18 ≤ H/L ≤ 0.26, R/L ≤ 0.11, 100˚ ≤ β1 ≤ 130˚, and 26˚ ≤ β2 ≤ 32˚, where D is the diameter of a fan, H the maximum height of a deflection, L the chord length of a blade, R the radius of the front edge on the inner peripheral side of the blade, β1 the entrance angle, and β2 the exit angle.
