Abstract
A room air conditioner and/or heat pump is shown having a compressor, indoor coil, accumulator, expansion device and reversing valve for changing between a cooling cycle and a heating cycle. Intake louvers direct return air over the entire indoor coil for maximum heat transfer. Discharge louvers are curved upward to prevent short cycling while still being totally adjustable, up and down, right and left. Adjustment posts are anchored to a clip and are adjustable for right or left discharge of air and up or down discharge. Single handles control both the right or left discharge through a rear set of louvers and up or down discharge through a front set of louvers. A no circulation area prevents short cycling and curved edges prevent turbulence in air flow through louvers.
