摘要 对复合EPS模板再生混凝土剪力墙的传热系数计算进行了研究.基于钢筋混凝土和EPS模板的导热机理,得出各材料导热系数与温度和湿度的关系计算表达式,提出符合围护墙体实际工作环境的传热系数修正计算方法.对比分析4个试件传热系数试验值、文献参考值及修正计算值,结果表明:采用修正计算方法能更准确地反映传热系数真实值,为建筑节能细化设计提供了理论基础.采用传热系数修正计算方法对适用于北京地区气候条件的复合EPS模板再生混凝土剪力墙传热系数进行计算和分析,并与文献参考值进行比较,结果表明:采用修正计算法进行节能设计更为合理. The heat transfer coefficient calculation of the composite EPS template recycled concrete shear-wall was studied in this paper. The relationship between heat transfer coefficients of various materials and temperature,humidity were calculated based on the heat conduction mechanism of the reinforced concrete and EPS template composite. A correction calculation method of heat transfer coefficient was put forward according with the actual working environment.By the comparative analysis of the experimental value,literature reference value and the correction calculation value of the four test specimens,the correction calculation value could more accurately reflect the real value coefficient of heat transfer,and provided a theoretical basis on building energy efficiency design. Taking the composite EPS template recycled concrete shear-wall that applicable to Beijing as an example,the heat transfer coefficient was calculated,analyzed,and compared with the experimental value,which suggested that the correction calculation method for energy saving design was more reasonable.
