Abstract: A low profile room air conditioner. The low profile is achieved in part by the arrangement of components in its outside section. The fan that moves air through the outside section is of the axial flow type mounted so that its axis of rotation is substantially perpendicular to the base of the enclosure and so that the fan draws air into the outside section through the top of the enclosure. Air discharges from the outside section through an air discharge on a side of the enclosure. Louvers at the air discharge direct the air exiting the enclosure away from the air inlet. A slinger directs droplets of condensate drained from the inside refrigerant-to-air heat exchanger into the air flowing through the outside section. The air carries the condensate on to the outside refrigerant-to-air heat exchanger where it evaporates. The air flow carries the resultant water vapor out of the outside section.

The threaded fastener is loosened to allow the position of the associated arm to be adjusted. The arms have an inner surface providing a series of radial teeth which mesh with like teeth on the outer surface of the housing when the threaded fastener is tightened, thereby retaining the arms in the desired position.
