ABSTRACT:
An energy recovery unit has an energy recovery wheel located in a plenum. Expelled air from the return duct is delivered to the plenum and after passing through the wheel is expelled by an exhaust fan through a side wall. Makeup air is delivered to the plenum and after passing through the wheel is supplied to the return duct by a fan. The makeup air follows a serpentine path from an intake in a side wall to the return duct.
