摘要/Abstract

摘要： 光致变色玻璃的透光率随光辐射强度的不同而变化,因此,光致变色玻璃可用于调控阳光进入建筑,是具有节能功效的智能玻璃。然而,目前光致变色玻璃在建筑中应用的研究较少,缺少科学评价其节能性能的方法。本文以制备的卤化银光致变色玻璃为研究对象,建立了光致变色玻璃节能性能简化模拟方法。利用DeST能耗软件研究了光致变色玻璃应用于不同建筑中的节能效果,计算和比较了两种变色特性的光致变色玻璃在不同建筑中的冷热负荷和照明能耗。研究结果显示:光致变色玻璃在建筑面积较大且窗墙比0.6以上的公共建筑中,全年节能率最高超过10%;在建筑面积和窗墙比较小的建筑中,其主要作用在于阻隔紫外线和防眩光。本文的方法和结果可为光致变色玻璃节能性能的研究提供参考,对光致变色玻璃的应用推广具有一定的促进作用。

Abstract: The transmittance of photochromic glass varies with the intensity of light radiation. Hence, photochromic glass is a smart glass with energy-saving effect, which can be used to regulate the sunlight into the building. However, there are few studies on the application of photochromic glass in buildings, and there is a lack of scientific methods to evaluate its energy-saving performance. In this paper, a simplified simulation method for energy-saving performance of the as-prepared photochromic glass was established. Focusing on the energy-saving effect, different types of buildings were modeled by the energy consumption software (DeST), and the cooling and heating load and lighting energy consumption of buildings with photochromic glass were calculated and compared. The results show that, photochromic glass has an annual energy-saving ratio up to more than 10% in public buildings with large building areas and window to wall ratio above 0.6. Furthermore, in buildings with smaller building areas and window wall ratio, its main role is to block ultraviolet light and prevent glare. The results and methods of this paper can provide a reference for the research of energy-saving performance of photochromic glass, and have significance to promote the practical application of photochromic glass.

Key words: photochromic glass, smart glass, building energy conservation, window wall ratio, lighting energy consumption, cooling and heating load
