HEAT EXCHANGE VENTILATION APPARATUS

摘要

Disclosed is a heat exchange ventilation apparatus provided with a total heat exchange element wherein a plurality of partition plates having a heat-transfer property, a moisture permeability, and a water resistant property are overlapped with one another while being spaced at a predetermined interval, to define interlayer passages between the partition plates, and an air intake path and an air discharge path alternately communicate with the interlayer passages; a first blowing unit and a second blowing unit, which respectively blow air through the air intake path and the air discharge path; and reversal units for respectively changing the direction of the airflow passing through the air intake path and the direction of the airflow passing through the air discharge path in the interlayer passages.
