Abstract
A centrifugal fan, which equally maintains air-blowing capacities of both inlets regardless of different suction resistances of both inlets due to a driving device, and an air conditioner having the centrifugal fan. The centrifugal fan includes a rotary plate; first blades disposed at the edge of one surface of the rotary plate; and second blades disposed at the edge of the other surface of the rotary plate, and having a larger outer diameter than the outer diameter of the first blades. Thus, although a large flow resistance is generated at one inlet of the centrifugal fan due to the driving device, air-blowing capacities of both inlets are maintained equally.
