METHOD OF MAKING AND USING A MEMBRANE FOR HEAT AND MOISTURE EXCHANGE BETRWEEN GAS STREAMS

A membrane for heat- and moisture-exchange between two gas streams is made by first coating a sheet-like textile support with a water-binding hygroscopic filler containing a binder, then heating the coated sheet-like support to between 140° C. and 240° C. The heated and coated support is deep drawn...

Zusammenfassung:A membrane for heat- and moisture-exchange between two gas streams is made by first coating a sheet-like textile support with a water-binding hygroscopic filler containing a binder, then heating the coated sheet-like support to between 140° C. and 240° C. The heated and coated support is deep drawn to impart to it a three-dimensional shape. Finally the deep-drawn coated support is interposed as the membrane between the streams such that moisture in one gas stream is transferred depending on moisture content or concentration level to the other gas stream, and heat is transferred depending on temperature differential.
