Abstract: An automatically operable dynamic purge system that is incorporated into a heat recovery wheel that comprises a number of radial seals that direct a controlled area of supply air into the exhaust air stream passing through the heat recovery wheel. Two possible configurations include a single purge and a double purge. For the single purge, one seal is fixed in location on one face of the wheel and a second seal is dynamic and is on the opposite face. For the double purge, two seals are fixed in location on one face of the wheel and a third seal is dynamic and is on the opposite face. In each case the dynamic seal is secured by an automatically operable wiper blade. This wiper blade is attached near the center of the wheel such that it rotates, in turn, allowing the seal to rotate while remaining approximately radial to the wheel.

Abstract: A rotary wheel system, including a rotatable frame with a plurality of removable, interchangeable media segments, has a hub assembly, a plurality of spokes radially extending from the hub assembly, in between which each media segment is located. Each I-beam shaped spoke is formed of a primary spoke and a secondary spoke, separated along the center section. The hub assembly includes specially designed brackets for detachably connecting the spokes to the hub assembly. A rim assembly includes a plurality of rim segments and special brackets for fastening each end of each rim segment to the spokes. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a reader to quickly ascertain the subject matter of the technical disclosure and will not be used to interpret or limit the scope of meaning of the claims. 37 CFR 1.72(b).
