摘要
针对可移动文旅舱的高窗墙比特征对室内光热物理环境所产生的不利影响,采用光热性能参数可调的电致变色玻璃(electrochromic,EC)窗替代普通玻璃窗并进行了动态控制策略多目标优化研究。首先,采用局部敏感性分析方法研究了EC窗对室内天然采光、热舒适与舱体能耗影响并与参考方案进行了对比;其次,应用Ladybug Tools性能模拟插件对不同朝向EC窗控制策略组合方案进行模拟,并结合Octopus多目标优化插件与TOPSIS评价法筛选得到不同气候区EC窗动态控制策略。结果表明:与2种参考玻璃窗相比,EC窗可有效改善舱体室内光热物理环境并降低运行能耗,所研究3个城市的有效天然采光照度、单位建筑面积能源消耗和室内热环境预计不满意率改善幅度分别为52%~68%、6.64~9.92 k W·h/m^(2)和2.87%~13.99%;不合理的EC窗控制策略会削弱提升效果甚至无法达到预期效果,在北京地区使用控制阈值分别为5000、20000和60000 lux的EC窗对应单位建筑面积能源消耗相比应用Low-E窗反而会增加3.17 k W·h/m^(2);得到舱体在3个城市的性能综合最优方案以及EC窗控制阈值的推荐值,这些数值将为可移动文旅舱体EC窗控制策略的设计和决策提供参考。
In response to the adverse effects of high window-to-wall ratios in movable cultural tourism cabins on indoor thermal and lighting environment,this paper adopted electrochromic(EC)glass windows with adjustable photothermal properties in place of ordinary glass windows and conducted a multi-objective optimization study of their dynamic control strategies.First,local sensitivity analysis was adopted to assess the impact of EC windows on indoor natural lighting,thermal comfort,and energy consumption compared to solutions for reference.The performance simulation plug-in Ladybug Tools was used to simulate the combined control strategies for EC windows in the same direction,and Octopus for multi-objective optimization and TOPSIS evaluation were integrated to screen and obtain dynamic control strategies for EC windows in different climate zones.Results showed that EC windows significantly improve indoor photothermal conditions and reduce energy consumption compared to reference windows in cabins in three cities,with improvements ranging from 52%~68%in natural lighting,6.64~9.92 kW·h/m^(2) in energy consumption,and 2.87%~13.99%in thermal comfort dissatisfaction.Incorrect EC window control strategies could negate these benefits and even failed to achieve expected effects.In Beijing,using EC windows with control thresholds of 5000,20000 and 60000 lux increased energy consumption by 3.17 kW·h/m^(2) compared to Low-E windows in the same unit area.Recommended optimal solutions for cabin performance and EC window control thresholds were derived,offering guidance for designing effective strategies in different cities.
