水平與垂直遮陽效果的解析研究

摘要：【中文摘要】 采用透光計算的方法,以深圳地區為研究對象,從直射、散射和總輻射的角度進行了水平和垂直遮陽系數的計算,分析了不同朝向水平、垂直遮陽裝置的全年遮陽特性,得到了冬、夏季遮陽系數計算公式的回歸系數,并與采用能耗計算方法得出的結果進行比較分析。結果表明,直射輻射遮陽系數和總輻射遮陽系數由于全年不同季節直射、散射所占比例不同而產生不同的變化趨勢,利用透光計算方法和能耗計算方法得到的遮陽系數有較好的一致性,并發現垂直遮陽不宜作為東西向遮陽方式。 【英文摘要】 The shading coefficients of the vertical and horizontal shading devices in Shenzhen based on the direct solar radiation,diffused radiation and the global radiation were calculated,and the annual performance of the horizontal and vertical shading devices in different building orientations was analyzed.The regression coefficients of the shading calculation formula for the winter and summer were got,and were compared with the results of the energy consumption calculation.The results show that direct radiation shading coefficient and the global radiation shading coefficient have the different change trends because of the different proportion between the direct radiation and the diffuses radiation,and the shading coefficients based on the light transmission calculation and the energy consumption simulation have the good consistency,and get the conclusion that vertical shading device is not suitable for west and east shading device. 【中文關鍵詞】 遮陽系數; 水平遮陽; 垂直遮陽; 透光計算【英文關鍵詞】 shading coefficient; horizontal shading; vertical shading; light transmission calculation
