Regenerative heat exchanger for dehumidification and air conditioning with variable airflow

摘要

A heat exchanger for cooling and/or dehumidifying a stream of air which eliminates the need for a large air diffusing plenum chamber. Heat conducting channel walls serve as the heat exchange surface for precooling and reheating air during the dehumidification process. The cooling conduits laterally intersect the airflow channels in order to force cooling to occur both in the intake and exhaust airflow channels, and the airflow is redirected 180 in a small plenum chamber located at an end of the channels adjacent the cooling conduits. Adjustable dampers may be added for additional control of airflow in and out of intake and exhaust ports for the purpose of regulating the cooling and dehumidifying processes.
