1. A method for the production of heat exchanger elements of a type for use in a residential or commercial total energy exchanger comprising:

  • a) producing a plate element with defined outer dimensions and corrugations in the area within a border, wherein the plate element is made from a material having sensible energy recovery capability;

    b) perforating the plate in predefined areas and in predefined dimensions, wherein said perforated area provides a plurality of holes allowing the water vapor to migrate from one side of the plate material to the other side;

    c) filling the perforations with a polymer with latent energy recovery capability, the filling being performed while the polymer is in a dissolved state, the polymer being selected to provide latent energy recovery of a residential or commercial space during a ventilation process where stale exhaust air and incoming fresh air travel through the heat exchanger; and

    d) curing the polymer onto the plate for forming a polymer layer within the perforations;

    wherein the polymer is a sulfonated block copolymer and the heat exchanger element is configured for placement in a total energy recovery ventilator (ERV), whereby the heat exchanger element exchanges heat as well as moisture with respect to air that flows in contact with the heat exchanger element.
