Abstract:
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 but adjacent to and linearly aligned with the fist path along at least a portion of their extents and adapted to remove moisture from a desiccant member, the first and second paths having a common separating wall therebetween, 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 precooking device, a cooling condenser device for condensing moisture from the second flow of air with an associated line extending through the second path following the cooling condenser device for removing condensed moisture from the condenser device in the second path to exterior of the second path, a reheating device coupled to the precooling device, and a heating device, the precooling device being one portion of a heat exchanger fixedly positioned immediately in advance of the precooling device and the preheating device being another portion of the heat exchanger fixedly positioned immediately in advance of the reheating device;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; anda final cooling component for the air to be dehumidified, the final cooling component having a first region in the first path between the desiccant wheel and the output end and having a second region outside of the first path, the final cooling component being a heat pipe with its second region in the path of flow of ambient air.
