ABSTRACT:
In an air conditioning system having the outdoor coil disposed in a wall opening with the outdoor air being required to flow horizontally inwardly pass through the coil and then flow horizontally outwardly as it is discharged, the propeller fan is placed in a horizontal plane at the top end of the coil such that the air is caused to flow into an upper plenum where the air is turned 90 degrees to be discharged. The height of the plenum is preferably chosen to optimize the performance while minimizing the plenum height.
