摘　　要：根据电路原理和克希荷夫电流定律,提出了一种计算建筑多层墙体的非稳定传热的热流网络模型3R2C仿真模型,该模型可用于模拟和分析多层围护结构非稳定传热。该方法简单易于编程实现,且比较和验证的结果表明这种模型在计算建筑围护结构非稳定传热时速度快、精度高、结果准确可靠。Based on circuit principle and Kirchhoff electric current theory, this paper presents a simple simulation model （3R2C model） of transient heat transfer through building envelope, which is applied to simulate and analyze the process of multilayer envelope transient heat transfer. This method is easy to program, and the results of comparison and test demonstrate that the 3R2C model is accurate, simple and efficient in calculating building envelope transient heat transfer.
