Abstract

An air conditioner with centrifugal blower capable of uniformizing an air velocity distribution at the diffusers of an indoor unit and increasing a heat exchange efficiency without increasing the size of the indoor unit, comprising the indoor unit (1), the indoor unit (1) further comprising a casing (11), a heat exchanger (30), and a turbo fan (40), wherein air passages (35b, 35d) leading to the plurality of diffusers (20) opposed to the direction of the air from the turbo fan (40) among air passages (35) leading from the turbo fan (40) to the plurality of the diffusers (20) through the heat exchanger (30) are disposed to be narrower than the other air passages (35a, 35c).
