摘要
分析了地下建筑的传热特性,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编制了相应的计算机程序,以此程序对地下厂房的热工环境进行了模拟,具体分析了壁面传热的主要影响因素。以分析模拟结果对地下建筑通风空调提供了一些参考意见。
This thesis analyses the heat transfer feature of underground structures, establishes the mathematical model of dynamic heat transfer of wall surfaces in the deep underground structures and introduces the reaction coefficient in the treatment of boundary conditions so as to solve the dynamic issues. The corresponding computer procedure is developed in accordance with the established heat transfer differential equation. Then, the thermal environment is imitated for the underground workshops so that the major factors influencing the wall surface heat transfer are further analyzed in specific. As a result, some referential suggestions are made in the light of imitation results for the ventilation and air-conditioning in underground buildings.
