ENTHALPY EXCHANGER ELEMENT AND METHOD FOR THE PRODUCTION

摘要

Enthalpy exchanger elements which allow the creation of enthalpy exchangers whereby the efficiency of sensible energy exchange and latent energy exchange can be varied and controlled and especially improved. Also, a method for the production of enthalpy exchanger elements is provided including • a) perforating a flat plate element (1) according to a predetermined perforation pattern within the plate outer dimensions; • b) forming the plate element (1) into a desired embossing pattern and geometrical shape; and • c) applying to at least one side (1 a) of the plate element (1) a polymer film (3) with water vapor permeation characteristics (water vapor transfer ratio, WVTR).
