Abstract
Abstract The invention relates to a humidity exchanger element comprising of a matrix formed by laminating single-faced corrugated sheets and an active silica-alumina aerogel just synthesized and adhered on said sheets and on the gap between the fibers of said sheets; the main constituents of said sheet being an inorganic fiber selected from the group consisting of ceramic fiber, glass fiber, slag fiber, carbon fiber and mixtures of them, the thickness of said sheet being in the range of 0.18-0.25 mm, the wave length of said corrugated sheet being in the range of 2.5-4.2 mm, and the wave height of said corrugated sheet being in the range of 1.5-2.3 mm; and the composition of said aerogel being 97-85% of silicon dioxide and 3-15% of aluminum oxide.
