摘　　要：叙述了构件动态传热的原理;介绍了ISO 13786国际标准对构件动态热作用的计算方法,对动态传热系数等参数的定义和计算公式给予了详细的描述;并通过6种典型墙体热工参数的计算,与我国目前构件动态热作用计算方法的分析对比,可以看出当选定构件动态传热系数小于0.5 W/(m2·K)作为隔热设计标准时,可以满足GB 50176给出的房间自然通风条件下构件的隔热要求;提出应参考ISO 13786的方法,改进我国构件动态热特性计算体系及评价方式。The dynamic heat transfer theory of building component is presented. Calculation methods of international standard ISO 13786 about dynamic thermal characteristics of building components are described. The definition and calculating equation of parameters such as periodic thermal transmittance etc. are given. Through thermal parameters calculation of six typical walls and analytic comparison with the methods applied in China, it is concluded that when periodic thermal transmittance is less than 0.5 W/（m2·K）as standard, it meets the requirement of GB 50176. It is proposed that ISO 13786 should be considered and utilized to improve the dynamic thermal characteristics calculation and evaluation methods of building components.
