一种确定墙体权重系数的简单方法

A Simple Method for Determining the Weighting Factors of Walls and Roofs

本文给出一种利用单层壁的反应系数,去求解多层壁墙体的权重系数的方法.该方法避免了传统求解多层壁墙体的权重系数时,丢根而引起的计算精度问题.同时,该方法计算量较小、简单灵活、速度快,便于建筑热工负荷计算和能耗模拟.

In this paper, a simple method for computing the weighting factors of walls androofs is developed, when the Z—heat transmission equations of a wall or a roof are obtained with the thermal response factors of its homogenous slabs, the weighting factors of it can be solved by a rational approximation method. This procedure can avoid the rootmissing problem involved in traditional method. An example has shown that it is superior and convenient for analyzing energy consumption of building.
