摘要 针对采暖房间的热平衡方程和墙体非稳态导热方程,给出了采用有限差分方法求解的基本步骤,并对某采暖房间的室内温度非稳态变化规律进行了数值计算和分析,得到了室内温度变化规律.结果显示,严寒地区墙体热惰性大,房间温度受室外温度波动影响较小. The finite difference method solving steps is given basing on the heat balance equation and the wall non-steady state heat conduction equation in this paper.The indoor temperature varying regulation is obtained by means of a numerical calculating and analyzing.As the large walls thermal inertia in cold area,the room temperature is less influenced by the outdoor air temperature.
