摘　　要：采用谐波法对同一建筑分别位于西安(寒冷地区)和哈尔滨(严寒地区)两地在供暖期其围护结构非稳态传热过程进行了分析,得到了两地室外综合温度拟合曲线以及南外墙内壁面的温度拟合曲线,比较了太阳辐射对严寒地区和寒冷地区室外环境的热作用效应时差.结果表明:非稳态传热分析方法所得结果更能体现室内环境通过围护结构对室外气象参数瞬时变化的动态响应机制.The harmonic wave method is used to analyze the unsteady heat transfer process of a building in Xi＇an（cold zone）and Harbin（severe cold zone）during the heating period.The outdoor sol-air temperature fitting curves and inner-surface temperature fitting curves of the south wall of the building located in two zones are obtained and the effects of solar radiation on outdoor thermal environment in two zones are compared.The results indicate that the unsteady heat transfer method can more accurately reflect the dynamic response mechanism that the indoor parameters are varied with the outdoor meteorological parameters through building envelope.
