ABSTRACT:
Console air conditioning units particularly useful for retrofit conversions, but having advantageous features for new installations as well. For retrofit applications, the console air conditioning units have the same "footprint" as an original package unit, and accordingly can be used to replace a worn-out console package unit without requiring any architectural changes. An indoor cabinet is subdivided at least into a plenum compartment having an air discharge opening and either a machinery compartment or a room air return compartment. The machinery compartment or room air return compartment occupies only a portion of the width of the cabinet, and a utility storage volume occupies an adjacent portion of the width. Preferably the plenum compartment is located in an upper portion of the cabinet above the machinery compartment or room air return compartment, and extends substantially the entire width of the cabinet along a wall. The machinery compartment may contain either a water-source heat pump or a simple fan/coil unit. The fan/coil unit may comprise a blower and a refrigeration system heat exchanger, or a blower and a heat exchanger supplied with chilled or heated fluid such as water. Alternatively an outdoor package unit may be located on the opposite side of the wall of the building and connected so as to draw in room return air via the room air return compartment and to discharge conditioned air via the plenum compartment.
