A method and apparatus for conditioning air through the removal of
moisture from air to be conditioned comprising a first path for a first flow of air to be dehumidified, the first path having an input end and an output end with a first blower between the input end and the output end to effect the movement of air from the input end to the output end; a second path for a second flow of air, the second path being independent of the first path and adapted to remove
moisture from the second flow of air, the second path being in a
closed loop configuration with a second blower for continuously moving the second flow of air around the second path and with a plurality of temperature changing devices sequentially positioned in the second path including an air precooling device, a cooling condenser device for condensing
moisture from the second flow of air, a reheating device coupled to the precooling device, and a heating device; and a
desiccant wheel with a motor to rotate the wheel in a continuous path of travel through a first zone and a second zone, the first zone being in the first path of travel between the input end and the output end, the second zone being in the second path of travel between the heating device and the precooling device.
