Abstract
An energy recovery wheel assembly includes a support frame, a motor, and a wheel rotor. The support frame at least partially defines an air-supply section that supplies outdoor air into a building and an air-exhaust section that removes indoor air from the building. The motor is coupled to the support frame. The wheel rotor is coupled to the support frame and driven in rotation about an axis relative to the support frame by the motor.
Claims20
An energy recovery wheel assembly comprising
- a support frame at least partially defining an air-supply section that directs outdoor air into a building and an air-exhaust section that directs indoor air from the building,
- a motor coupled to the support frame, and
- a wheel rotor coupled to the support frame and driven in rotation about an axis relative to the support frame by the motor, the wheel rotor including an outer case, a wheel mount coupled to the support frame, and energy absorption media located between the outer case and the wheel mount,
- wherein the energy absorption media is made up of a plurality of sheets, the energy absorption media having a depth within a range of about 15 inches to about 40 inches, each sheet having a thickness within a range of about 0.003 inches to about 0.01 inches.

An energy recovery wheel assembly comprising
- a support frame at least partially defining an air-supply section that directs outdoor air into a building and an air-exhaust section that directs indoor air from the building,
- a first wheel rotor coupled to the support frame and configured to rotate about an axis relative to the support frame, and
- a second wheel rotor coupled to the support frame and configured to rotate about the axis relative to the support frame,
- wherein the first and second wheel rotors each include energy absorption media that is configured to transfer at least one of heat and moisture between air flowing through the air-supply section and air flowing through the air-exhaust section as the first and second wheel rotors are rotated about the axis.

A method of recovering energy from air in a building, the method comprising
- displacing outdoor air from outside of the building through an air-supply section of an air handling unit toward an interior of a building,
- displacing indoor air from the interior of the building through an air-exhaust section of the air handling unit that is separate from the air-supply section,
- rotating a first wheel rotor about an axis that extends parallel to and is located between the air-supply section and the air-exhaust section,
- rotating a second wheel rotor about the axis,
- wherein the first and second wheel rotors each include energy absorption media that is configured to transfer at least one of heat and moisture between air flowing through the air-supply section and air flowing through the air-exhaust section as the first and second wheel rotors are rotated about the axis.
