Cross flow air to air heat exchanger
WebJul 30, 2024 · Generally, heat exchangers are classified by the way the air moves through the unit. In a counter-flow exchanger, hot and cold air streams flow parallel in opposite directions. In a cross-flow unit, the air … WebA cross-flow air exchanger has the two air streams going in a perpendicular motion. Whether you choose a cross-flow air-to-air exchanger or a counter-flow air-to-air exchanger depends solely on your needs. Counter-flow heat exchangers are generally long and rectangular. Efficiency ratings are somewhere around 80%. Cross-flow heat …
