Method and apparatus for supplying conditioned fresh air to an indoor area

A fresh air supply unit comprising:

• a housing having a first side and a second side, a first opening being disposed in said first side, a second opening and a third opening being disposed in said second side;
• an enthalpy wheel having a first side facing surface and an opposite second side facing surface, said enthalpy wheel being rotatably mounted within said housing, approximately half of said second side facing surface being in fluid communication with said second opening, approximately the remaining half of said second side facing surface being in fluid communication with said third opening, substantially the entire first side facing surface being in fluid communication with said first opening;
• and
• a partition being disposed in said housing between a predetermined location on said second side of said housing between said second opening and said third opening and extending to said enthalpy wheel to define, in part, a first air flow path and a second air flow path within the housing, said first air flow path extending between said second opening through said enthalpy wheel to said first opening, said second air flow path extending from said first opening through said enthalpy wheel to said third opening,
• a thermoelectric chip being disposed in said partition, said thermoelectric chip having a first surface in fluid communication said first air flow path and a second surface in fluid communication said second air flow path.
