摘　　要：介绍了DeST中基于状态空间法建立的建筑动态热过程模型。首先介绍了建立建筑热过程模型中的主要问题和基本方程 ,指出建立建筑热动态模型必须求解壁体传热的偏微分方程 ,必须同时考虑构成房间的各个部件的影响以及房间之间的相互影响。以此为前提 ,详细介绍了DeST对这些问题的处理方法和具体算法 ,并以实例阐明DeST对建筑热环境的模拟分析。最后为了突出状态空间法的特点 。Explains the dynamic building thermal process model of DeST based on state space solution method. Starts with a presentation of problems to be encountered and the equations to be solved when constructing such a thermal process model. Points out that it is imperative to solve the heat transfer equations of opaque envelopes correctly and consider the interaction among components in a room and among rooms in a building in details. Then describes detail procedures on how to solve these problems and how to carry out a building thermal environment simulation by DeST with some examples. Finally compares the state space method with other solution methods.
