摘　　要：利用墙体热工系统分析了节能外墙构造方式对围护结构延迟和衰减作用的影响,以银川地区居住建筑为例,计算了具有相同传热系数和热惰性指标的不同构造方式的墙体对室外温度扰量的延迟时间与衰减倍数,比较分析了三种墙体的保温方式对室外温度扰量平抑能力的差异。分析结果表明,墙体构造方式对热稳定性有明显的影响,其中外保温构造衰减倍数最大,而夹芯保温构造延迟时间最长。With the wall thermal system the paper analyzes the impact of energy-saving exterior wall configuration form on the time lag and decrement factor.Taking the residential buildings in Yinchuan areas for example,the paper calculates the time lag and decrement factor to the disturbance quantity of the outdoor temperature for the walls of different configuration forms with the same heat-transfer coefficient and heat inertia index,the paper also analyzes the difference of stabilizing ability to the disturbance quantity of the outdoor temperature in three kinds of wall thermal insulations.The results show that the wall configuration form has obvious effect on the thermal stability,in which the decrement factor of the outside thermal insulation configuration form is maximum,while the sandwich thermal insulation configuration form has the longest time lag.
