The air flows through the heat exchanger 46 and the orifice 56 and is drawn into the centrifugal fan 52 and blown in the radial direction of the centrifugal fan 52 by the centrifugal fan 52.

The air blown from the centrifugal fan 52 toward the left scroll housing 60 is blown in a substantially downward direction while swirling along the lower portion of the cut off 62, and then the cut off of the right scroll housing 70 ( After passing between the 72 and the lower portion of the left scroll housing 60 is spread to the left and right is discharged downward through the lower air discharge port (8).

And, the air blown toward the right scroll housing 70 among the air blown in the radial direction of the centrifugal fan 52 is blown upwards while being flowed along the upper portion of the cut-off 72, and then the top It is blocked by the vanes 82 and its flow direction is directed to the top of the left scroll housing 60 so as to pass between the cut off 62 and the centrifugal fan 52 of the left scroll housing 60, and the cut off 62. It is blown upwards as it flows along the lower part of the bottom. The air flowing into the left scroll housing 60 by the upper vanes 82 is merged with the air blown from the centrifugal fan 52 to the left schole housing 60 as described above, and the cut of the right scroll housing 70 is performed. After passing between the off 72 and the lower portion of the left scroll housing 60 is spread to the left and right and discharged downward through the lower air discharge port (8).

That is, in the heating operation of the air conditioner, the air blown in the radial direction from the centrifugal fan 52 passes along the right schol housing 70, the upper vane 82, and the left scroll housing 60. It flows in the direction of the swing and then flows through the lower air discharge port (8), and is discharged toward the lower portion of the room while being guided by the lower vanes 102 to raise the room from the bottom of the room to the top to heat the room.
