在笛卡儿坐标中使用交变方向的隐有差分法于几种掩土建筑造型已经求解了二维瞬时富立叶热传导方程。结构与从安装在普通住宅地下室的仪器中取得的数据比较,验证了这种计算机程序。本模型考虑了可变的土壤性质,不同类型下地坪造型以及热绝缘的各种类型、厚度和位置。虽然在本论文中仅仅提出了对于土复盖结构的结果,然而该程序已被用来分析普通地下室、土护道墙和复盖结构中内部和外部绝缘的各种等级的热脉冲。通过外部建筑围护层的热损失和热获得是位置和年度时间以及建筑材料,绝缘和土壤几何形状的函数。建筑围护材料中和周围土壤中的温度分布与年度时间的关系已表示出来。同时作了经济分析以指出所分析的绝缘等级的经济效益。
In the Cartesian coordinates, the two-dimensional instantaneous Fourier heat conduction equation has been solved for several kinds of cover building modeling using the alternating difference implicit difference method. The structure was validated against data obtained from instruments installed in the basement of a common house. This model considers variable soil properties, different types of floor sculpting, and various types, thicknesses, and locations of thermal insulation. Although only the results for the soil cover structure are presented in this paper, the program has been used to analyze various levels of thermal pulses inside and outside the insulation in common basements, earth retaining wall and cladding structures. The heat loss and heat gain through the external building envelope are a function of location and annual time as well as building materials, insulation and soil geometry. The temperature distribution in the building envelope material and in the surrounding soil has been expressed in relation to the annual time. At the same time, an economic analysis was made to indicate the economic benefits of the analyzed insulation class.
