摘要
通过采用EnergyPlus软件分别研究了安徽合肥地区在非空调环境下电致变色玻璃窗对办公建筑室温和热舒适性影响,以及在空调环境下,电致变色玻璃窗对办公建筑能耗的影响.结果显示,在无空调环境下,与普通6 mm玻璃窗相比,夏季高温时间减少了 245 h,全年热舒适时间增加了 753 h;与Low-E玻璃窗相比,夏季高温时间减少了164 h,全年热舒适时间增加了 333 h.而在有空调环境中,电致变色玻璃窗的全年能耗相比于6 mm普通玻璃窗提高了 23.9％,相比于Low-E窗提高了 7.7％.电致变色玻璃窗可以有效改善室内热环境、提高室内的热舒适并且可以显著减少能耗.
Abstract
This paper used EnergyPlus software to study the impact of electrochromic glass windows on room temperature and thermal comfort of office buildings in Hefei,Anhui Province in non-air-conditioned environment;and the impact of electrochromic glass windows on office building energy consumption in air-conditioned environments.The results show that in a non-air-conditioned environment,compared with ordinary 6mm glass windows,the high temperature time in summer is reduced by 245 hours,and the annual thermal comfort time is increased by 753 hours throughout the year;compared with Low-E glass windows,the high temperature time in summer is reduced by 164 hours,and the annual thermal comfort time is increased by 333 hours.While,in an air-conditioned environment,the annual energy consumption of the electrochromic glass windows is 23.9％higher than that of the 6mm ordinary glass windows,and 7.7％higher than that of the Low-E windows.Electrochromic glass windows can effectively improve the indoor thermal environment and the thermal comfort and can significantly reduce energy consumption simultaneously.
