Energy recovery ventilator with condensate feedback

摘要

Condensate accumulating in the incoming outside air flow passages of a heat exchanger is fed back into the exhaust flow passages of the heat exchanger to provide improved heat transfer in the heat exchanger, and to avoid the necessity for drainage of the condensate from the heat exchanger. The heat exchanger includes a plastic multi-tube panel core and a solid plastic housing, with opposed-flow heat exchange and inlet-outlet extensions from only one side of the core.
