摘　　要：为了更好地发挥电致变色玻璃主动调控光谱的属性,为电致变色玻璃在建筑上的应用提供理论指导,以两玻一腔中空玻璃为例讨论了可见光透过率和遮蔽系数(节能效果)变化。研究发现,获得更大的可见光透过率差(褪色态-着色态)重点是要提高电致变色玻璃透过率,但相比于成本更高的电致变色玻璃,提高Low-E玻璃透过率更为现实。为了更大限度地发挥电致变色玻璃的节能特性,分别将电致变色玻璃放置于中空玻璃的室内侧与室外侧测试,结果表明当电致变色玻璃位于室外侧时,遮蔽系数变化幅度最大(0.46),更能适应多种场景下的使用,但同时也对电致变色玻璃的膜层性能提出了更高的要求。In order to make better use of the properties of active spectrum control of electrochromic glass and provide theoretical support for the application of electrochromic glass in architecture,the sealed insulating glass unit was taken as an example to discuss the changes of visible light transmittance and shielding coefficient(energy saving effect).It is found that in order to obtain a larger visible light transmittance difference(bleach state minus color state),the key point is to improve the transmittance of electrochromic glass.However,compared with the electrochromic glass with higher cost,it is more realistic to improve the transmittance of Low-E glass.In order to give full play to the energy-saving characteristics of electrochromic glass,the electrochromic glass was placed on the outdoor side and indoor side of insulating glass respectively for testing.The results show that when the electrochromic glass is located on the outdoor side,the change of shielding coefficient is the largest(0.46),which is more suitable for a variety of scenarios.At the same time,the better performance of electrochromic glass film is required.
