摘要
以白玻璃窗、Low-e玻璃窗、电致变色玻璃窗为研究对象，通过EnergyPlus软件模拟，分析了采用眩光控制的电致变色玻璃窗在不同气候区对太阳直射辐射透过量以及散射辐射透过量的影响。Low-e玻璃窗太阳辐射透过量约为白玻璃窗的1/2。白玻璃窗总辐射透过量与电致变色玻璃窗的透过量的比值范围为9.5～18，相对于散射辐射透过量，电致变色玻璃对直射辐射透过量的影响较大。在上海、广州、昆明可完全消除眩光，而哈尔滨和北京仍然存在眩光现象。
Abstract
This paper adopts the EnergyPlus software to analyze the properties of the transmitted beam and diffuse solar radiation for the electrochromic window in five climate zones, as well as the clear glass window and the Low-e window. The control strategy of the electrochromic window is glare control. The Low-e’s transmitted solar radiation decrease about 50% compared with the clear glass window. The ratio of total transmitted solar radiation of the clear window and electrochromic window is from 9.5 to 18. Compared with the diffuse solar radiation, the eletrochromic window has a greater effect on the transmitted beam under glare control strategy. The glare phenomenon can be completely eliminated in Shanghai, Guangzhou and Kunming, while not in Harbin and Beijing.
