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.
Claims17
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, each discrete panel comprising a cut portion of the first and the second water-vapor-permeable membrane sheets attached to respective opposing sides of a cut portion of the separator material;
- 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.
