SYSTEM MIT VERGLASUNGSELEMENT UND GASVERSORGUNGSVORRICHTUNG

WO2003021344 A UPAB: 20030513 NOVELTY - The system comprises a glazing element (2) and a gas supply device (4). The glazing element has substrates (18,19) enclosing an intermediate chamber (3) and a gas having a defined composition. A surface of the glazing element facing the intermediate chamber has a coating with controllable optical and/or electrical properties. DETAILED DESCRIPTION - The gas supply device comprises an electrolysis unit comprising a working electrode, a counter electrode and an electrolyte for producing a gas. The glazing element and the gas supplying device are connected together so that the gas can be introduced between the glazing element and the gas supply device in a closed cycle (6). Devices for influencing the moisture content of the gas are arranged in the system. PREFERRED FEATURES:- The coating is made from an electro-chromic layer, preferably made from tungsten oxide, molybdenum oxide, titanium oxide, chromium oxide, vanadium oxide, cerium oxide, iridium oxide, manganese oxide, cobalt oxide, niobium oxide or nickel oxide, and/or electro-chromic polymers; or is a metal hydride layer containing rare earth and/or transition metals. USE - Used for glazing buildings or windows of vehicles, aircraft and ships. ADVANTAGE - The system is simple and reliable.
