|
摘要
本文以南京地区为代表,研究夏热冬冷地区的通风双层玻璃幕墙建筑使用现状,选择南京已投入使用的通风双层玻璃幕墙建筑(银城大厦)作为实地热工测试对象,测试对比房间室内外原始工况基本相同。冬季日间,进行了两组通风双层玻璃幕墙不同建筑朝向对比测试、六组不同通风方式和遮阳条件的热工对比测试(以南朝向为例)；夏季日间,进行了一组能耗对比测试、五组不同通风方式和遮阳条件的热工对比测试(以南朝向为例)；夏季夜间,进行了三组不同通风方式的热工对比测试、四组不同遮阳条件的热工对比测试(以南朝向为例)。根据测试结果,对于通风双层玻璃幕墙建筑,在冬季白天首先考虑无遮阳条件。当室外具有良好的太阳辐射时,开启内层幕墙,进行内循环通风方式；夏季日间应采取遮阳条件和外循环的通风方式；夏季夜间通风能有有效的带走室内余热,达到降低室内温度的效果,采用同时开启外循环内循环的通风方式能够达到最佳的效果。
本文同时对通风双层玻璃幕墙冬季、夏季不同工况进行了理论分析和建模,结合南京银城大厦通风双层玻璃幕墙的各项参数,编制程序,对通风双层玻璃幕墙的各层温度,热通道内的空气流速,通风双层玻璃幕墙的综合传热系数进行计算,并分析太阳辐射对其的影响。
最后使用DeST能耗模拟软件对通风双层玻璃幕墙,普通钢化玻璃幕墙,普通中空玻璃幕墙建筑进行全年建筑能耗模拟,对不同朝向、不同气候分区的通风双层玻璃幕墙建筑进行全年能耗模拟和分析。
This paper describes the use conditon of the double glass curtain wall in hot summer and cold winter, taking Nanjing for example. Choose Nanjing Silver City Building for example, the double curtain wall buliding that built and put into use in Nanjing. Select two same condtion rooms both inside and outside conditions as the experimental room. In winter, there are two thermal tests for different directions, and six thermal tests for different shade and ventilation conditions, In the summer day, there is a thermal test for energy consumption of air-conditoning and five thermal tests for different shade and ventilation conditions. In a summer night there are three tests for different ventilation conditions and four tests for different shade conditions. According to test results, during a winter day, shade condition should be first considered in a double glass curtain wall building. When the outdoor solar radiation has a good time, open the inner wall, for ventilation inside. During a summer day, shade conditions and ventilation outside should be taken; During a summer night, summer night ventilation effectively remove indoor heat, to reduce the indoor temperature effect, both ventilation outside and inside should be taken to achieve optimal results.
Thermal performance of the double glass curtain wall is analyzed in this paper,both in the winter and in the summer. According to the parameters of the double glass curtain wall of Nanjing Silver City Building and the thermal analysis of glass curtain wall above, a program is made,which can calculate the temperature of the layers of the double glass curtain wall, the air velocity inside the heat channel, the integrated heat transfer coefficient of the double glass curtain wall. And the effect of solar radiation is also analyzed.
DeST, an energy simulation software, is used to simulation the year-round energy consumption of the building with double glass curtain wall, single glass wall and hollow glass wall.
