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.

- 9. A heat exchanger element comprising a plate element with defined outer dimensions and corrugations to increase the exchange surface in the area within a border, said border being defined by a peripheral rim that extends completely around the area containing the corrugations, the peripheral rim including a first portion that is open along a corresponding edge of the plate and defines one of an inlet and an outlet of a flow channel, the first portion lying in a different plane relative to adjacent portions of the peripheral rim so as to represent a locally deformed area of the peripheral rim, said inlet or outlet of the flow channel being spaced from the corrugations and is therefore only defined by a non-corrugated portion of the plate, the plate element being further defined by a first face and a second face, said plate element being made from a material having sensible energy recovery capability, and said plate element has perforations in predefined first areas and in predefined dimensions, each perforated area providing a plurality of perforations, each perforation being made so as to extend from the first face to the second face, said perforations being filled with a polymer with latent energy recovery capability, wherein the polymer comprises a sulfonated block copolymer that has a water vapor transmission rate suitable for use in a total energy recovery ventilator (ERV).

16. A method for the production of an energy recovery ventilator (ERV) that is defined by a plurality of heat exchanger elements comprising:
-
a) producing a plurality of plate elements, each plate element having defined outer dimensions and corrugations in the area within a border that extends completely around the area containing the corrugations, wherein the plate element is made from a material having sensible energy recovery capability, wherein the entire border is free of corrugations and defines free edges of the plate element; b) perforating the plate in predefined areas within the border and in predefined dimensions and locations, wherein said perforated area provides a plurality of holes; c) filling the perforations with a polymer with high latent energy recovery capability, the filling being performed while the polymer is in a dissolved state and by a technique that results in the polymer being directed into the perforations, wherein said plurality of holes when filled with the polymer allows the water vapor to migrate from one side of the plate material to the other side; d) curing the polymer onto the plate for forming a polymer layer within the perforations; and e) combining the plurality of plate elements in stack form to define the energy recovery ventilator that is configured for residential and commercial applications to receive both exhaust air and incoming air, wherein the plurality of plate elements are constructed to act upon both the exhaust air and the incoming air by heat and moisture exchange therebetween. - View Dependent Claims (17, 18, 24)
