HIGH EFFICIENCY SENSIBLE AND LATENT HEAT EXCHANGE MEDIA WITH SELECTED TRANSFER FOR A TOTAL ENERGY RECOVERY WHEEL

摘要

A sensible and latent heat exchange media comprises a gas permeable matrix. The gas permeable matrix provides passageways therethrough through which an air stream can flow through the sensible and latent heat exchange media. The gas permeable matrix is formed of a sensible heat exchange material that is capable of absorbing sensible heat from a warm air stream and releasing the absorbed sensible heat into a cool air stream as the air streams flow through the sensible and latent heat exchange media. A layer of a coating composition comprising a molecular sieve is applied to at least a portion of the surface of the sensible heat exchange material. The molecular sieve has a plurality of pores of a substantially uniform size such that the molecular sieve is capable of adsorbing moisture from a humid air stream flowing through the sensible and latent heat exchange media, and is capable of releasing the adsorbed moisture into a dry air stream flowing through the sensible and latent heat exchange media, but is not capable of adsorbing contaminants from either of the air streams. The sensible and latent heat exchange media is extremely efficient in transferring both sensible and latent heat between air streams.
