建筑环境设计模拟分析软件DeST第2讲 建筑动态热过程模型
Building environment design simulation software DeST(2): dynamic thermal process of buildings
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,从算法和建立动态热过程模型的方式上对该方法与其他几种方法进行了比较。
Abstract:
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.
