据专家统计,建筑物室内的热能耗散量中大约有1/2～2/3是以人体和室内各物体所发射出的长波段红外线形式从窗口散发掉的为了节能就必须有效地防止红外线从窗口辐射掉。最近,美国一家平板玻璃生产厂研制成一种具有优良隔热性能的新型平板玻璃,就具有阻挡红外线穿透的能力。即在一般的平板玻璃上,采用一种真空喷镀的工艺,沉积上一层超薄的金属膜层。从外表上看,这种新型玻璃与普通玻璃并无差别,但是.它却能将室内射向该玻璃的红外线反射回去
According to expert statistics, about 1/2 to 2/3 of the heat energy dissipated in a building’s interior is emitted from the window by long-wavelength infrared radiation emitted by human bodies and indoor objects. In order to save energy, it must effectively prevent infrared rays. Radiate from the window. Recently, a flat glass production plant in the United States has developed a new type of flat glass with excellent thermal insulation properties, which has the ability to block infrared penetration. That is, on a typical flat glass, a vacuum sputtering process is used to deposit an ultra-thin metal film layer. From the outside, this new type of glass is no different from ordinary glass, but it can reflect the infrared rays emitted from the room to the glass.
