Flow inside. The wind blown to the heat exchanger 5 has a reduced wind speed by the amount of air passing through the heat exchanger 5. The wind flowing inside the connecting plate 11 has no passing air volume, so that the wind speed does not decrease. After passing through the inside of the connecting plate 11, the wind hits the cut-and-raised portion 13 a of the rectifying plate 12, where it is rectified and passes through the heat exchanger 5. The wind passing through the heat exchanger 5 is cooled or heated,
The air is blown into the room from the outlet 9 as cold air or hot air.
