空心玻璃微珠薄膜对建筑物外围护结构隔热性能的影响

Effect of Hollow Glass Microsphere Thin Film on Heat-Insulation Performance of Building Envelope

分析了建筑物外围护结构采用单层玻璃、双层玻璃及其外表涂覆空心玻璃微珠(HGM)薄膜时的隔热性能,以及HGM薄膜的传热系数和隔热效率,并采用建筑能耗分析模拟软件DOE-2对其隔热效率进行计算.结果表明:在建筑物及其外窗玻璃表面涂覆HGM薄膜后,能够有效降低建筑物的室内温度;在建筑物普通外墙表面涂覆HGM薄膜后,也可降低其室内温度.

The heat-insulation performance of the building envelope with sing-layer plate glass,double-layer plate glass and hollow glass microsphere（HGM）thin film as well as the heat conductivity coefficient and heat-insulation performance of HGM thin film were analyzed,and a simulation software DOE-2was used to calculate heat-insulation performance of buildings in this paper.The results show that the buildings and window glasses coated with HGM can efficiently decrease the room temperature,and the outer wall with HGM can decrease the room temperature,too.
