摘　　要：准确地确定围护结构动态热特性模型,有利于建筑室内热环境的设计和建筑节能。随着当今计算机速度的不断提高,有限体积法得到了很大的发展。应用有限体积法对华东地区加气混凝土墙体进行非稳态传热研究,并与传统的实心粘土砖外墙能耗进行比较,指出在该地区使用加气混凝土外墙可以实现墙体节能50%的目标。It is useful to determinate accurately the model of thermal dynamic characteristics of building envelop for thermal environment design of inner room and building energy saving.With the increase of operation speed of computer, finite volume method has been substainfially developed. Using this method study on transient heat transfer through the wall made of autoclavecured aerated light weight concrete in the east part of China was made. Energy consumption of such wall mentioned above was compared with that of tradtional brick wall.The result indicated that 50 percent of energy consumeption through wall would be saved when autoclavecured aerated concrete wall was used instead of solid clay brick one.

关 键 词：有限体积法 非稳态传热 加气混凝土外墙 节能
