电致变色玻璃窗对上海居住建筑室内热环境的影响

Effect of electrochromic window on thermal environment for a residential building in Shanghai

采用EnergyPlus软件研究了非空调条件下电致变色玻璃窗对室内空气平均温度和热舒适的影响。结果表明,与Low-E玻璃窗相比,夏季和秋季电致变色玻璃窗房间室温高于29℃的时间分别减少了217h和13h,春季、夏季和秋季的舒适时间分别增加了19,135,132h。电致变色玻璃窗可以改善室内热环境并提高室内的热舒适。

Based on the use of the EnergyPlus software,analyses the effect of Low-E window and electrochromic window on indoor mean air temperature and thermal comfort in a residential building in Shanghai under non-air-conditioned environment.The results show that compared with the Low-E window, the cumulative time of the room temperature higher than 29 ℃in the room with the electrochromic window decreases 217 hours in summer and 13 hours in autumn respectively.Meanwhile,the thermal comfortable time increases 19 hours in spring,135 hours in summer,132 hours in autumn respectively.Electrochromic window can improve indoor thermal environment and thermal comfort.
