A SEAL FOR ENERGY RECOVERY WHEELS HAVING SPACED APART LATERAL WALLS

摘要

The present relates to a seal for an energy recovery wheel. The seal comprises a main body defining an inner surface, and a pair of lateral walls extending from each lateral side of the main body. Each lateral wall respectively comprises a free edge defining a lip. The inner surface and lateral walls define a space therebetween. The seal provides for air travelling from one section of the energy recovery wheel to another to turbulate within the space. The inner surface is generally flat and the space may comprise a cavity. The lateral walls may be flexible or rigid. The present also relates to a combination of the seal with the energy recovery wheel.
