ABSTRACT:
A console package air conditioning unit of the split-system type, particularly useful for retrofit conversion, but useful for new installations as well. The console package air conditioning unit is the same physical size as a self-contained package console unit being replaced, but contains essentially just an indoor heat exchanger and a blower for recirculating indoor air over the indoor heat exchanger. Being of the same physical size and having the same "footprint", the worn-out package unit is replaced without requiring any architectural changes. The left-over interior volume realized by removing the system compressor and outdoor heat exchanger to an outdoor unit is utilized as a utility storage volume, such as bookshelves. There are both a room air return opening for allowing room air to be drawn in over the indoor heat exchanger, and a ventilation opening for allowing outside air to be drawn in by a blower. The cabinet interior is subdivided into an upper plenum compartment extending substantially the entire width of the cabinet along the wall, and an indoor heat exchanger compartment occupying only a portion of the cabinet width. An air discharge opening is formed in a wall of the plenum compartment, likewise extending the width of the cabinet, and the blower pressurizes the plenum compartment. In one embodiment, a controllable damper system is provided for selectively controlling the amount of air drawn in through the room air return opening and through the ventilation opening.
