摘要:【中文摘要】 采用透光計(jì)算的方法,以深圳地區(qū)為研究對(duì)象,從直射、散射和總輻射的角度進(jìn)行了水平和垂直遮陽(yáng)系數(shù)的計(jì)算,分析了不同朝向水平、垂直遮陽(yáng)裝置的全年遮陽(yáng)特性,得到了冬、夏季遮陽(yáng)系數(shù)計(jì)算公式的回歸系數(shù),并與采用能耗計(jì)算方法得出的結(jié)果進(jìn)行比較分析。結(jié)果表明,直射輻射遮陽(yáng)系數(shù)和總輻射遮陽(yáng)系數(shù)由于全年不同季節(jié)直射、散射所占比例不同而產(chǎn)生不同的變化趨勢(shì),利用透光計(jì)算方法和能耗計(jì)算方法得到的遮陽(yáng)系數(shù)有較好的一致性,并發(fā)現(xiàn)垂直遮陽(yáng)不宜作為東西向遮陽(yáng)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(guān)鍵詞】 遮陽(yáng)系數(shù); 水平遮陽(yáng); 垂直遮陽(yáng); 透光計(jì)算【英文關(guān)鍵詞】 shading coefficient; horizontal shading; vertical shading; light transmission calculation
