ਸ਼੍ਰੇਣੀ ਆਰਕਾਈਵ Counterflow heat exchanger

In the counterflow heat exchanger, two neighboring aluminum plates create channels for theair to pass through. The supply air passes on one side of the plate and the exhaust air onthe other. Airflows are passed by each other along parallel aluminum plates instead ofperpendicular like in a crossflow heat exchanger. The heat in the exhaust air is transferredthrough the plate from the warmer air to the colder air.
Sometimes, the exhaust air is contaminated with humidity and pollutants, but airflows nevermix with a plate heat exchanger, leaving the supply air fresh and clean.
