【摘要】 窗户是影响空调房间室内负荷的一大因素。其不仅有温差带来的导热和对流,还有阳光透过窗户与室内辐射换热,从而相对其他围护结构对室内负荷的影响更大。针对夏热冬冷区,以上海地区气象参数为代表,采用冷负荷系数法[1-3]模拟计算了多种遮阳设施下的室内空调冷负荷,从而比较各个种类窗遮阳设施对于空调房间室内负荷的影响。结果表明,采用内外遮阳结合设施之后的窗与无遮阳装置的相比,节能效果更好。在采用的遮阳措施中,以0.4m水平探出遮阳板、内悬挂浅色窗帘及双层玻璃效果最明显。 【Abstract】 Windows is a major factor affecting air-conditioning load. It brings heat conduction and convection caused by temperature difference,as well as the heat transferring by sun radiation,which has greater impact on air-conditioning load compared with other building envelopes. Focusing on the temperature parameters of Shanghai region featuring for hot-summer and cold-winter,the cooling load coefficient method [1-3] is applied to simulate a variety of sunshade facilities for a comparison. The results show that,using the windows with internal and external sun-shade facilities has lower air-conditioning load compared with non-shading ones. Among the selected sun-shading measures,the 0.4m level sun shields,light-colored curtains and double-glazing windows are most effective in energy-saving. 【关键词】 玻璃窗; 遮阳板(外遮阳); 内遮阳; 室内空调冷负荷; 上海 【Key words】 windows; sun shield(external shading); internal shading; indoor air-conditioning cooling load; Shanghai
