厚重型建筑围护结构的传热计算方法

A method for the heat transfer calculation of thick-and-heavy envelope

黄土高原的厚重型被覆围护结构建筑是一种独特的居住建筑,围护结构的传热过程是其室内热环境研究的关键。本文作者首次提出运用有限元和有限差分结合,研究了厚重型被覆围护结构在动态条件下的传热过程,并建立了厚重型被覆围护结构建筑室内热环境的动态数值计算方程组。数学模型计算实例的计算结果与测试数据吻合较好,计算方法正确可行。

The thickandheavy dwelling building in the loess plateau is a unique residential building in the world.To study the heat transfer process of the thickandheavy envelope is a key step for simulating the indoor environment of the dwelling building with thickandheavy enclosure. It's first to combine the method of the finite element and the method of the finite difference to study the heat transfer through the thickandheavy enclosure of the dwelling building.The dynamic equations have been drawn up. A comprehensive program has been worked out based on the mathematical model, the unit dividing may be more handy by using the pretreatment program. The result of this model may be seen to support much more well the experimental conclusions. Based on the above analysis, this paper verifies the validity of the combining method of the finite element and the method of the finite difference to study the heat transfer through the thickandheavy envelope.
