An air conditioning system is provided which utilizes both exhaust and outside air energy to regenerate the latent and sensible heat removal operations while not detrimentally increasing the bacterial contamination risks associated with exhaust air energy recoupment. The air conditioning system includes a supply air passageway through which supply air flows during conditioning thereof and a desiccant wheel for reducing the humidity of supply air in the supply air passageway. The system also includes separate exhaust air and outside air passageways. A first circulation assembly is provided for circulating a heat transfer medium between a refrigerant-type cooling assembly and a first transfer zone disposed in the exhaust air passageway and a second circulation assembly is provided for circulating a heat transfer medium between the cooling assembly and a second transfer zone disposed in the outside air passageway. Since the exhaust air is not mixed with the outside air, the outside air can be used to regenerate the desiccant wheel during its movement through the second heat transfer zone without risk of harmful bacterial growth promotion associated with the use of exhaust air in direct contact with the supply air.

[ What is claimed is:] [1.] A system for conditioning air to be supplied to an interior space, comprising:means defining a passageway through which supply air flows during conditioning thereof, the supply air passageway being communicated with the interior space for delivery of conditioned supply air to the interior space;means for advancing supply air along the supply air passageway;means for reducing the humidity of supply air in the supply air passageway, the humidity reducing means being recircularbly movable between a supply air contact area in which it contacts supply air to receive water content therefrom and thereby reduce the humidity of the supply air and a regeneration area in which water content is removed from the humidity reducing means;means for cooling reduced humidity supply air, the cooling means being disposed downstream of the humidity reducing means;means defining an exhaust air passageway separate from the supply air passageway for the flow therethrough of an air stream constituted of at least exhaust air received from the interior space;means defining an outside air passageway separate from the supply air passageway and the exhaust air passageway, the outside air passageway for the flow therethrough of outside air received from outside of the interior space;first circulation means for circulating a heat transfer medium between the cooling means and a first transfer zone disposed in the exhaust air passageway; andsecond circulation means for circulating a heat transfer medium between the cooling means and a second transfer zone disposed in the outside air passageway, the passage of outside air into contact with the second circulation means resulting in a heat exchange between the heat transfer medium and outside air by which the outside air is heated to become increased heat content outside air and the heat transfer medium is cooled, the heat exchange in said second transfer zone further resulting in the vaporizing of moisture in said outside air, and the regeneration area for regenerating the humidity reducing means being disposed downstream of the second transfer zone in the outside air passageway for receiving increased heat content outside air in a regeneration process by which the increased heat content outside air removes water content of the humidity reducing means.
