Abstract
An interior unit of a split type air-conditioning apparatus which is usually mounted on a wall of a room to be cooled and is extremely thin. The unit consists of a cabinet structure including a front panel, a middle frame and a rear plate, said front panel having an air inlet opening and an air outlet opening. Also included is a centrifugal fan, preferably a turbo fan with a plurality of backward curved blades, specially designed to adapt to the unit. The means for driving said fan are designed to be partly accommodated in the body of the turbo fan for the purpose of decreasing the depth of the unit.
