摘要
为研究影响兰州地区住宅建筑供暖能耗的因素,在围护结构参数完全符合国家现行寒冷地区住宅建筑节能要求的前提下,以兰州市2栋住宅建筑为基准模型,运用De ST-h软件对供暖季的热负荷进行逐时模拟计算,分析窗墙比、体型系数、朝向三大因素对总供暖热负荷的影响,得到了兰州地区住宅建筑南偏西30°朝向与南偏东30°朝向、正南方向相比,总热负荷最小,但最大热负荷最大的结论,为南偏西建筑进行供热调节实现节能提供依据。南向墙面内凹的住宅建筑不宜通过面积热指标法来估算热负荷。
In order to study the influence factors of Lanzhou area residential buildings of heating energy consumption,under the premise of envelope parameters in full compliance with the current national cold region residential buildings energy-saving efficiency requirements,regarding Lanzhou city two residential buildings as benchmark models,using DeST-h software to calculate the heat load in all heating season,analyzing the window-wall ratio,shape coefficient,towards of three factors effect for the all heating load,the main conclusions of the calculations are follows:the Lan zhou area 30 degrees west of south towards compared 30 degrees east of south towards and due south towards of the total heat load are minimum,but the maximum thermal load are maximum,so the South West building heating regulation is energy-saving measures.The south wall of concave residential buildings are not suitable to estimate the heat load by area thermal index method.
