Webenergy recovery wheels and certain types of fixed-plate heat exchangers with permeable membranes can trans-fer latent, and therefore total, energy. Effectiveness The ratio of … Web( Enthalpy is a measure of heat.) As the wheel rotates between the supply and exhaust air streams it picks up heat energy and releases it into the colder air stream. The driving force behind the exchange is the difference in temperatures between the opposing air streams (the thermal gradient).
