摘　　要：为了改善双层玻璃幕墙的节能效果,利用水的高显热蓄热能力,设计了一套家用水循环玻璃幕墙。利用电子水泵将卫生间水箱中的水注入双层玻璃幕墙中间夹层,并定时置换,通过热工计算,比较了不同家用节能玻璃幕墙的热工性能,计算结果显示:温度每上升1℃,水循环玻璃幕墙吸热量为Low-E玻璃幕墙和中空玻璃幕墙的3240倍。计算结果表明,该设计的家用水循环玻璃幕墙可以有效降低夏季室内温度,具有良好的节能作用。To improve the energy - saving effect of double glass curtain wall and use high sensible heat storage capacity of water,the article designs a system of household glass curtain wall with water cycle. The system uses electronic pumps bringing the water from toilet tank into the double glass curtain wall and regularly replaces the water. Through thermal calculation,the article compares the thermal performance of different household energysaving glass curtain wall. The results show that when the temperature increases by 1 degree Celsius, the heat absorption of glass curtain wall with water cycle is 3240 times of the Low - E glass curtain wall and hollow glass curtain wall＇s. The results show that the design of household glass curtain wall with water cycle in the article can effectively bring down the indoor temperature in su mmer and has good energy saving effect.
