摘要
建筑节能设计中外墙保温材料选择不当,导致传热性能较差,因此,本文以外墙内外保温层厚度理论为基础,通过计算外墙节能设计墙体平均传热系数,构建外墙导热数值模拟模型。通过模拟实验可知,建筑节能设计中外墙设计可显著减小建筑墙体内外温差,提升墙体内部温度,增加室内温度均匀性;数值模拟计算的墙体平均传热系数结果与试验实测值具备较好的一致性,并降低了建筑能源消耗,具有一定的借鉴意义。
Improper selection of thermal insulation materials for exterior wall in building energy-saving design results in poor heat transfer performance, therefore, this paper based on the theory of the thickness of the inner and outer insulation layer of the outer wall,the outer wall design was carried out, and the numerical simulation model of the heat conduction of the outer wall was constructed by calculating the average heat transfer coefficient of the energy-saving design of the outer wall. Through the simulation experiment, it could be seen that the exterior wall design could significantly reduce the temperature difference between the inside and outside of the building wall, improve the internal temperature of the wall, and increase the indoor temperature uniformity;the average heat transfer coefficient of the wall calculated by the numerical simulation was consistent with the measured value of the test, and reduced the energy consumption of the building, which had a certain reference significance.
