玻璃是现代生活中重要的建筑材料和生产材料。第一代单层玻璃热阻很小,而且对远红外热辐射几乎完全吸收,传热系数高达6.4W/(m~2·K)左右,是240厚砖墙的4倍左右;第二代粘接密封中空玻璃,由于不产生空气对流的中间层,虽具有一时的隔声、隔热、防结露、降低冷辐射的功能,但其传热系数 Glass is an important building material and production material in modern life. The thermal resistance of the first generation of single-layer glass is very small, and almost completely absorbed by far-infrared heat radiation, the heat transfer coefficient is as high as 6.4W / (m ~ 2 · K) or so, which is about 4 times of that of 240- Adhesive sealed insulating glass, because the air convection does not produce the middle layer, although with a temporary noise, heat insulation, anti-condensation, reducing the function of cold radiation, but the heat transfer coefficient
