Abstract
A turbofan to reduce noise through a suppression of turbulent air flow at an outlet thereof and also to guide the air discharged from the outlet in a specific discharging direction, and an air conditioner equipped with the turbofan to improve an efficiency of a heat exchange. The turbofan includes a rotating plate coupled to a shaft of a drive motor, a plurality of blades radially arranged on a peripheral area of a front face of the rotating plate, a ring-shaped shroud joining to ends of the plurality of blades, and a flow guide rib extending from a peripheral edge of the rotating plate in a rearward direction to guide the air discharged from the turbofan.
