一、问题的提出时值腊月寒冬,室外滴水成冰,室内开着暖气或空调,温暖如春。室内、外为何有如此大的温差呢?究其原因,建筑中的双层玻璃窗的贡献是巨大的。在我国东北地区,最低气温达到零下30℃,所以一般的建筑都是采用双层玻璃窗的。近年来,在我国的南方地区,现代家庭和办公场所也陆续开始采用双层玻璃窗户设计。稍微有一点物理知识的人都知道,双层玻璃窗具有减少热量从室内向室外传播从而达到保暖的作用。但要是被问到双层玻璃窗为什么具有保暖效果呢?具体保温功效有多少呢?
First, the issue of the value of the twelfth lunar month, outdoor dripping ice, indoor heating or air conditioning, warm spring. Why indoor and outdoor so much temperature difference? The reason, the double-glazed windows in the building’s contribution is enormous. In northeastern China, the minimum temperature reached minus 30 ℃, so the general construction is the use of double glazing. In recent years, in the south of our country, modern homes and offices have also begun to adopt double-glazed windows design. A little bit of physical knowledge knows that double-glazed windows have the effect of reducing heat transfer from the interior to the exterior for warmth. However, if asked why double glazing has a thermal effect? Specific insulation effect how much?
