Abstract

An air conditioner comprising a cylindrical bellmouth (8) for conducting the room air, a centrifugal fan (10) for radially blowing the air sucked through the bellmouth (8), and a heat exchanger (9) provided facing an outlet (10b) of the centrifugal fan (10), all of which being provided in a casing (2). A shroud (5) of the centrifugal fan (10) has a guide section (5c) which is provided radially outwardly of and contiguous to an annular blade support (5b) to extent toward a suction side in an axial direction, the guide section (5c) effectively reducing blast sounds.
