【英文篇名】 Hourly analysis of the influence of shading coefficient on heating and cooling energy consumption 【作者中文名】 龙恩深; 王勇; 肖益民; 付祥钊; 【作者英文名】 By Long Enshen; Wang Yong; Xiao Yimin and Fu Xiangzhao Chongqing University; Chongqing; China; 【作者单位】 重庆大学; 【文献出处】 暖通空调, Hv 空调; 供暖; 建筑能耗; 节能率; 【英文关键词】 sun-shading coefficient; air conditioning; heating; building energy consumption; energy efficient rate; 【摘要】 以中国福州为例,从当地逐时气象数据入手,分析了建筑空调负荷及供暖负荷的所有时刻对应的逐时太阳辐射,用特征温度法研究当遮阳系数减小时各时刻建筑的空调与供暖能耗及相对变化(节能率)情况。研究发现,由于冬季有太阳辐射各时刻的供暖能耗相对于无太阳辐射各时刻能耗比例很小,故遮阳措施对供暖总能耗的影响不显著,从而证明DOE2关于冬季遮阳系数减小对供暖能耗影响的结论值得商榷;由于夏季有太阳辐射各时刻空调能耗远大于无太阳辐射各时刻空调能耗,故遮阳措施对空调总能耗及节能率的影响非常显著,DOE2软件与特征温度法的结果是正确的;通过对福州全年各时刻空调供暖能耗、建筑负荷及节能率进行解析,揭示了看起来很分散的各时刻能耗及节能率差异数据总体上遵循的某种共性规律,供同行参考。 【英文摘要】 Taking Fuzhou,China as an example and starting with its hourly meteorological data,analyses the hourly solar radiation in all hours with building cooling/heating load and studies the hourly cooling and heating energy consumption and its relative variation rate (energy efficient rate) of the building by using the characterized temperature method when shading coefficient decreases. Finds that the proportion of the heating energy consumption in all the hours with solar radiation in winter to the annual heating...
