Abstract

An air conditioning unit in which a housing is provided having side walls adapted to extend within an opening formed in an exterior wall of a room to be cooled. Air inlet and outlet means are associated with the front wall and rear walls of the housing to circulate room air and ambient air through the unit. A condenser heat exchanger and an evaporator heat exchanger are disposed in the housing in proximity to its rear wall and front wall, respectively, and extend at an angle relative to the latter walls. Ambient air is circulated into the inlet associated with the rear wall, across the condenser heat exchanger and out the outlet associated with the rear wall, and room air is circulated through the inlet associated with the front wall, across the evaporator heat exchanger and out the outlet associated with the front wall.
