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.

Claims (5)

1. An energy recovery unit comprising a plenum, an energy recovery unit located within the plenum and passing through a divider that subdivides the plenum into a pair of compartments, an expelled air duct extending from an inlet through one of said compartments to an exhaust, a makeup air duct extending from an inlet through another of said compartments to a discharge, said intake and said exhaust being located on oppositely directed walls of said unit and said intake and discharge being located on a common wall.
2. An energy recovery unit according to claim 1 wherein said makeup air duct follows a serpentine path from said intake to said discharge.
3. An energy recovery unit according to claim 2 wherein said makeup air duct includes a chamber between said intake and discharge and a fan is located in said chamber to force air to said discharge.
4. An energy recovery unit according to claim 3 wherein said chamber is located between said other compartment of said plenum and said discharge.
5. An energy recovery unit according to claim 1 wherein said expelled air duct includes an inlet portion and an exhaust chamber separated by said one compartment, said exhaust chamber and said inlet portion being juxtaposed with an exhaust fan in said chamber.
