Abstract
A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels,

A method for making a heat and humidity exchanger core, the method comprising:
- forming a plurality of discrete panels, wherein forming each of the plurality of discrete panels comprises attaching first and second water-vapor-permeable membrane sheets to opposing first and second sides respectively of a corresponding separator;
- and
- stacking the plurality of discrete panels in a spaced-apart relationship, wherein stacking the plurality of discrete panels in a spaced-apart relationship comprises providing a plurality of spacers between each pair of adjacent ones of the discrete panels to provide a channel between each pair of stacked adjacent ones of the discrete panels.
A method for making a heat and humidity exchanger core, the method comprising:
- a) forming a laminated material, wherein forming the laminated material comprises attaching first and second water-vapor-permeable membrane sheets to opposing sides of a separator material;
- b) cutting the laminated material into a plurality of discrete panels;
- and
- c) stacking the discrete panels in a spaced-apart relationship by providing a plurality of spacers between each pair of adjacent ones of the discrete panels to provide channels between the discrete panels of each pair of adjacent ones of the discrete panels.
A panel for use in an ERV core, the panel comprising:
- a separator having projections to either side of a plane of the separator;
- first and second water-vapor-permeable membrane sheets attached to the projections on opposing first and second sides of the separator, the separator holding the first and second water-vapor-permeable membrane sheets in a spaced-apart parallel relationship, wherein the projections cooperate with the first and second water-vapor-permeable membrane sheets to provide channels extending laterally across the panel between the separator and the first and second water-vapor-permeable membrane sheets.
