摘要
鉴于夏热冬冷地区的气候特点．针对外保温、内保温和复合墙板的保温三种不同的保温形式，计算墙体构造特性，建立ANSYS有限元模型对比分析不同构造墙体的热工性能。模拟结果表明：外保温墙体的温度波衰减度大，延迟时间更长，抵抗室外温度波变化能力强，热稳定性更好。
According to climatic characteristics of the hot summer and cold winter zone,considering the 3 different forms of heat preservation,including external insulation ,internal insulation and thermal insulation of compositive wall, this paper calculated the characteristics of wall construction, established ANSYS finite element model to compare and analyze the thermal performance of different types of wall. The results of simulation show that the exterior insulation has more attenuation and longer delay time , stronger resistance against wave changes in outdoor temperature and better thermal stabiliity.
