<p>An enthalpy exchanger, comprising a heat-conducting wall along both sides of which two respective media can flow in mutual enthalpy-exchanging contact, which wall is provided with a hydrophilic cover layer with at least the following properties: (a) a strong adhesion; (b) a substantially complete covering; (c) a maximum thickness of 50 µm; (d) a heat resistance which is small relative to the total heat resistance; (e) a moisture absorption capacity such that water absorbed during wetting spreads as a film over the cover layer; (f) little surface roughness; (g) little susceptibility to degradation, erosion, growth of micro-organisms and adhesion of dirt; (h) morphological, chemical and physical uniformity; which cover layer is applied by chemical means by first activating each relevant surface and subsequently forming the cover layer by chemical reaction from an aqueous solution.</p> |
