ABSTRACT:
A unitary humidity exchange cell (HUX) is dislosed that includes at least one composite membrane, disposed between at least one first chamber for flow of the first fluid therethrough and at least one second chamber for flow of the second fluid therethrough. The composite membrane include an at least partially sulfonated humidity-conducting polymer comprising residues derived from at least one arylvinyl monomer; and a reinforcing substrate bonded thereto. The product finds utility in a variety of physical and chemical processes and products whereby moisture or other highly polar liquid or gas transfer, exchange removal or delivery is important. A notable application is the Membrane Energy Recovery Ventilator (MERV) in which both heat, ions and moisture is transferred between two air streams, one intake and one exhaust, from an air-conditioned building.
