An air conditioner includes a unit casing, an impeller, a scroll casing,
and a heat exchanger. The unit casing is partitioned by a partition
member into a fan chamber and a heat exchanger chamber. The heat
exchanger is disposed inside the heat exchanger chamber so as to face a
scroll blowout opening in the scroll casing. The scroll casing is
disposed inside the fan chamber. A wall section projects from a heat
exchanger side of a flat plate section of the partition member and is
disposed outside a scroll outlet section of the scroll casing.
