ABSTRACT:
A heat exchanger for dehumidifying a stream of air including heat conducting channel walls which serve as the heat exchange surface for precooling and reheating air during the dehumidification process. Cooling conduits are positioned in a plane parallel to a plane defined by the heat conducting walls, such that cooling occurs both in the intake and exhaust airstreams, and the airflow is redirected in a small plenum chamber located at an end of the channels adjacent the cooling conduits. A system is also provided which includes a plurality of heat exchangers in series sharing a common cooling coil and a common plenum chamber.
