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.
Claims11
An air conditioning apparatus comprising:
- a pair of heat exchangers, one of said pair of heat exchangers being a heater and the other of said pair of heat exchangers being a cooler,
- means for adjustably mounting said heat exchangers adjacent an air stream path defined by a conditioned air duct having an air inlet and an air outlet, said air duct including a side wall with a pair of openings, each of said pair of heat exchangers being movable through one of said openings into and out of said duct between said air inlet and said air outlet,
- means for independently moving each heat exchanger between a position withdrawn from said air stream path through a partially inserted intermediate position in which a portion of said heat exchanger is located within said air stream path, and a fully inserted position, such that when both heat exchangers are within said air stream path said heater is downstream of said cooler,
- control means operatively associated with the means for moving each heat exchanger for regulating the position of each heat exchanger relative to said air stream path among any of a position withdrawn from the air stream path, a partially inserted position and a fully inserted position, the control means including means for sensing an air condition in said air stream path downstream of said heat exchangers to coordinate the positions of each of said heat exchangers among any of the positions of each of said heat exchangers among any of said positions to maintain air delivered through said air stream path at a pre-set desired air condition.
