Abstract

This indoor unit for an air conditioner is provided with: a casing (1); a centrifugal fan (30) which is disposed in the casing (1); a heat exchanger (40) which is disposed in the casing (1) so as to surround two or three sides of the centrifugal fan (30); and a partition part (50) which together with the heat exchanger (40) surrounds the centrifugal fan (30), and which connects one end of the heat exchanger (40) with another end of the heat exchanger (40), and guides blown out air of the centrifugal fan (30) from the side of the one end of the heat exchanger (40) to the side of the other end of the heat exchanger (40). The distance (L) between the centrifugal fan (30) and the partition part (50) is longer at the side of the other end of the heat exchanger (40) than at the side of the one end of the heat exchanger (40).
