摘　　要：动态性是围护结构传热的本质属性,动态热响应机理是其动态运行规律的体现。围护结构在夏季的动态性比在冬季表现更为典型,因此该文开展隔热建筑的围护结构动态性机理及应用研究。通过研究围护结构的动态热响应机理提出围护结构最大防热量G_(max),该指标兼顾多种工况下围护结构热性能的评价。以夏热冬冷地区的重庆为例进行模拟分析。研究发现:G_(max)<60 W/m^(2)时,提升墙体最大防热量可有效提升其动态热响应性能;G_(max)在60~90 W/m^(2)之间时,提升墙体最大防热量可较少提升其动态热响应性能;G_(max)>90 W/m^(2)时,提升墙体最大防热量反而会降低其动态热响应性能。The dynamic property is the essential property of heat transfer in the envelope,and the dynamic thermal response mechanism is the embodiment of its dynamic operation law.The dynamic behavior of the envelope structure in summer is more typical than that in winter.Therefore,this paper studies the dynamic mechanism and application of of thermal isolation building envelope.By investigating the dynamic thermal response mechanism of the building envelope,this paper propose a novel metric called G_(max),which comprehensively evaluates the thermal performance of the envelope structure under diverse operational conditions.Chongqing,which is hot in summer and cold in winter,is taken as an example for simulation analysis.The results show that when G_(max)<60 W/m^(2),the dynamic thermal response performance can be effectively improved by increasing the_(max)imum heat isolation G_(max)of the wall.When G_(max)=60~90 W/m^(2),the dynamic thermal response performance can be less improved by increasing G_(max).When G_(max)>90 W/m^(2),the dynamic thermal response performance of the wall will be reduced by increasing G_(max).
