PLATE-TYPE CROSSFLOW AIR-TO-AIR HEAT EXCHANGER HAVING DUAL PASS COOLING

摘要

A heat exchanger (40) for dehumidifying a stream of air including heat conducting channel walls (42) which serve as the heat exchange surface for precooling and reheating air during the dehumidification process. Cooling conduits (48) are positioned in a plane parallel to a plane defined by the heat conducting walls (42), such that cooling occurs both in the intake and exhaust airstreams, and the airflow is redirected in a small plenum chamber (44) located at an end of the channels adjacent the cooling conduits (48). A system is also provided which includes a plurality of heat exchangers in series sharing a common cooling coil and a common plenum chamber.
