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,
Claims27
A heat and moisture exchanger comprising:
- a plurality of panels, each of the panels comprising
- a flexible separator formed to provide projections to either side of a plane of the separator;
- and
- first and second thin water-vapor-permeable membrane sheets attached to the projections on opposing faces of the separator, the separator holding the first and second water-vapor-permeable membrane sheets in a spaced-apart parallel relationship, the panel stiffened by the attachment of the membrane sheets to the separator, the projections formed to provide first channels operable for carrying a first flow between the separator and the first and second water-vapor-permeable membrane sheets in a first direction across each of the panels;
- the panels stacked in a parallel spaced-apart relationship to provide open second channels between adjacent ones of the panels, the second channels extending to carry a second flow through the heat and moisture exchanger in a second direction transverse to the first direction.

A panel for use in an ERV core, the panel comprising:
- a separator formed to provide projections to either side of a plane of the separator;
- first and second water-vapor-permeable membrane sheets attached to the projections on opposing faces of the separator, the separator holding the first and second water-vapor-permeable membrane sheets in a spaced-apart parallel relationship, the projections formed to provide channels extending across each of the first and second water-vapor-permeable sheets between the separator and the sheets.

A method for making a heat and humidity exchanger, the method comprising:
- forming a plurality of panels by attaching first and second membrane sheets to opposing sides of a separator formed to provide projections to either side of a plane of the separator, the first and second membrane sheets attached to the projections;
- and
- stacking the panels in a spaced-apart relationship with spacers separating the panels to provide channels between each pair of adjacent panels.
