摘　　要：电致变色玻璃是1种新型节能玻璃。对电致变色玻璃的光学性能和热工性能进行了测试,并与普通玻璃和低辐射镀膜玻璃的性能进行对比分析。分析结果表明,电致变色玻璃具备4个变色状态,不同变色状态的节能效果不同;最暗状态的遮阳系数最低;各状态下的传热系数基本不变。建议电致变色玻璃与低辐射镀膜玻璃配合使用,不仅可同时增强遮阳效果和保温效果,还能有效降低夏季制冷和冬季制热的建筑能耗。Electrochromic glass is a new type of energy-saving glass.Working principle and energy saving effect of electrochromic glass have not been well known to the public.In this paper,the optical and thermal properties of typical electrochromic glass were tested in the laboratory,and compared with ordinary glass and Low-E glass.The analysis results show that intelligent electrochromic glass has four color-changing states,and each state has different energy-saving effects,in the darkest state,shading coefficient is lowest,but U values is basically unchanged in each state.It is recommended to use it with Low-E glass to enhance the shading effect and thermal insulation effect at the same time,which can effectively reduce the building energy consumption of cooling in summer and heating in winter.
