摘要
基于地下建筑的传热机理 ,建立了深埋地下建筑壁面动态传热的数学模型 ,在边界条件的处理上引进了反应系数 ,使动态问题得以解决 ,依据建立起的传热微分方程及边界条件 ,编制了相应的计算机程序 ,应用此程序对地下厂房的热工环境进行了模拟 ,计算出洞室全年壁面吸放热量以及全年逐日出口温度 。
Based on the heat transfer mechanism of underground structure,a mathematical model on the mechanism of heat transfer is set up .The coefficient of response into boundary conditions to make the dynamic problem is solved.The corresponding computer program is drawn up according to the heat transfer differential equation and boundary conditions, and the thermal environment of underground plant is stimulated by using this program.The simulated results include quantity of heat transfer through walls and outlet temperature day by day in a year are calculated .The scientific guideline for the final cooling load and the choice of air conditioner are provided.
