摘要
为利用空调冷凝水的冷量同时解决单层玻璃幕墙夏季高温的问题,将冷凝水用于冷却单层玻璃幕墙,并对其进行了水量、造价及能耗分析.通过Ecotect、CFD模拟、对比了冷凝水冷却玻璃幕墙与普通玻璃幕墙在夏季的光环境和热环境.结果表明:冷凝水冷凝水冷却玻璃幕墙应用规模与建筑冷凝水产量有关,其应用会减少夏季日照辐射,减少幅度在30.1%~41.8%.加装了冷凝水冷却玻璃幕墙的房间温度较普通房间降温幅度为6.64%,白天降温幅度在6.64%~12.73%.综合分析,冷凝水冷却单层幕墙能够较为有效地调节室内环境,同时也是一种新的建筑幕墙改良途径和冷凝水利用方式.
Air conditioning condensate water was combined with glass facade in order to utilize the cold of condensate water and decrease the high temperature of glass facade. The condensate water quantity, cost and energy consumption of the condensate water cooling glass facade were analyzed. At the same time, room’s light and thermal environment with condensate water cooling glass facade and ordinary glass facade were compared by using Ecotect, CFD simulation in summer. The results showed that the area of condensate water cooling glass facade was related to the condensate water quantity in buildings. The application of condensate water cooling glass facade can reduce the sunshine radiation from 30.1%~41.8%. Its indoor air temperature can reduce 6.64% compared with the ordinary room, the daytime cooling range is 6.64% ~ 12.73%. In summary, condensate water cooling single glass facade can improve the indoor environment effectively and reduce the temperature of the glass facade, and it is a new way of unitization of air conditioning condensate water.
