摘要
在建筑的供暖和空调系统设计中,太阳辐射对供暖和空调负荷有重要的影响.合理遮阳是暖通空调领域节能的一个途径.根据天津地区典型气象年的气象资料,对该地区住宅建筑南向墙遮阳板的构造进行建模分析,并对其节能前景进行预测.在保证冬季日照的前提下,对于天津地区南向墙遮阳板宽度宜取0.5～0.9m,距窗户上沿距离0.5～0.8m.安装遮阳板后,南向窗每个夏季可减少太阳辐射得热80～110MJ/m2.
Solar radiation has great effects on heating and cooling load of buildings. Therefore, window shading has energy-saving potential in the field of heating ventilating and air conditioning (HVAC). The effect of solar gain of exterior shade on southern windows is simulated according to typical meteorological year data of Tianjin. Simulation results show that the width of southern window shade should be 0.5—0.9 m and the distance between shade and upside of windows should be 0.5—0.8 m in Tianjin to ensure sunlight and solar radiation received by windows in winter, and the reduction of solar gain through southern windows of buildings in summer can be 80—110 MJ/m^2.
