ABSTRACT:
An air conditioning apparatus (1) is disclosed which includes a pair of adjacent parallel air ducts, namely a conditioned air duct (4) and an ambient air duct (5), wherein the ducts (4,5) have a common side wall (7). A fan (14) delivers an air stream through the conditioned air duct (4) to condition the air stream. A fan 15 delivers ambient air through the ambient air duct (5). Mounted within the ambient air duct (5) is a refrigeration unit having a condenser (20) and an evaporator (21). The condenser (20) and evaporator (21) are slidable between the two ducts (4,5) along tracks (43,46) extending through openings (25,26) in the side wall (7) to condition air passed through the conditioned air duct (4) to a pre-set desired condition.
