Heat Recovery Wheels are positioned within supply and exhaust air streams of an AHU in order to recover the heat energy.
In other words, the wheel is positioned in an AHU so that it is divided into two half moon sections.
Stale exhaust air is drawn through one half and fresh outdoor air through the other in a counter flow pattern. The wheel is in rotation all this while.
Sensible heat is transferred as the metallic substrate picks up and stores heat from the warmer air stream and gives it up to the cooler one.
Latent heat is transferred as the desiccant coating on the metallic substrate adsorbs moisture from the air stream that has the higher humidity ratio and releases the moisture into the air stream that has the lower humidity ratio.
