摘要
在建筑负荷、系统模拟和能耗分析时,为了获得准确的室内负荷和能牦,传导传递函数(CTF)系数的准确性是至关重要的。然而,当CTF方法计算CTF系数时,很有可能产生不准确甚至错误的结果。鉴于此,本文通过改变单层、三层和六层板壁中材料层的厚度、导热系数、密度以及比热的大小,详细分析了当前应用非常广泛的CTF系数计算方法——状态空间法、直接求根法和频域回归法的适应性和可靠性,并分析了它们产生误差的根源,以便人们在计算和使用CTF系数时,提高精度和避免误差。计算结果表明:当板壁为轻型和中型时,状态空间法和直接求根法保持了良好的精度和稳定性,其相对误差的绝对值都小于5%;当板壁越来越重型时,状态空间法和直接求根法的计算精度开始大幅度波动,其最大相对误差达到了:17.34%和16.83%(单层),38.7%和-17.49%(三层),81.61%和-72.50%(六层)。不管是单层还是多层板壁,也不管板壁特性参数怎么变化,频域回归法相对误差的绝对值都不超过0.6%。总之,频域回归法的计算精度和适应性是三种方法中最好的,而直接求根法的计算精度和适应性稍好于状态空间法。
     随着建筑地上围护结构的隔热保温日益加强,由地下结构传热引起的建筑能耗就变成建筑总能耗中越来越重要的部分。因此,充分、透彻分析和研究地下结构与大地之间的热传递过程,并进一步研究其能耗状况及其计算方法,就成为一件刻不容缓的事情。以往的计算方法大多都采用了传统的数值方法,例如有限差分法、有限元法和有限体积法等,它们都是以单元或网格为基础的,编程实现和实际应用比较复杂和困难。为了克服传统数值方法的这些不足,本文引进一种摆脱了单元或网格的束缚,编程容易实现,而且前、后处理过程非常简单的数值方法——无单元伽辽金方法,来处理复杂的地下结构二维传热问题,并在其求解导热偏微分方程的基础上,分析和研究地下结构的传热特性和能耗状况,从而为工程和设计人员提供依据和参考。本文的具体研究工作及主要结论如下:
     1.第3章引入了无单元伽辽金方法。首先介绍了形函数的构造方法——移动最小二乘法的基本原理;其次,介绍了权函数的选取原则,影响域的确定原则,第一类边界条件的处理方法,并且引进了形函数及其导数的快速算法;然后,从变分原理出发,得到了拉格朗日乘子法和罚函数法系统离散方程组:最后,介绍了程序实现步骤以及计算伽辽金弱形式积分的高斯-勒让德方法,在高级编程语言MATLAB工作平台上自主开发了无单元伽辽金方法程序。
     2.第4章分析了权函数及其影响域的放大系数对无单元伽辽金方法计算精度和收敛率的影响。计算结果表明:无单元伽辽金方法具有非常高的计算精度和收敛率,四次样条权函数最适合处理导热问题。当罚参数取值合适时,罚函数法与拉格朗日乘子法具有相当的计算精度。罚函数法非稳态分析的CPU时间比拉格朗日乘子法少。当放大系数增大时,不管是哪一种权函数,无单元伽辽金方法CPU时间均有大幅度增加。
     3.地下结构传热模型包括了墙壁、地板、屋顶、地基、基脚、砾砂层以及大地土壤层等,考虑了地下水位线和隔热保温对地下结构室内能耗的影响。
     4.提出了基于基准节点间距的分区均匀布置节点方法产生无单元伽辽金方法的离散节点。
     5.对地下水位线、远场边界、土壤导热系数、室外风速以及屋顶离地表面距离分别进行了灵敏度研究,分析了它们对稳态传热地下结构室内能耗的影响,分析了隔热保温层的厚度、长度以及布置位置对稳态传热地下结构室内能耗的影响。
     6.提出了预先计算三个周期的初始条件确定方法,采用3个周期后准稳定分布温度场作为初始条件,计算结果表明这种方法是正确的、合理的。
     7.地下结构非稳态传热的室内能耗对土壤导热系数的变化非常灵敏,因此,确定土壤导热系数需特别谨慎。
     8.隔热保温使得地下结构非稳态传热的地板、墙壁和屋顶热流的振幅和均值的绝对值大幅度减小,时间延迟大幅度增加。
     9.北京地区室外温度的年周期变化最为明显,其次是日周期变化;大地土壤层对室外温度波的衰减剧烈,特别是对周期较短振幅较小的温度波,地下结构越深,衰减程度越大。
Conduction transfer function (CTF) is widely used to calculate conduction heal transfer in building cooling/heating loads and energy calculations. The limitation of a methodology possibly results in imprecise or false CTF coefficients. There are three popular methods, state-space (SS) method, direct root-finding (DRF) method and frequency-domain regression (FDR) method to calculate CTF coefficients. The second chapter of this dissertation investigated the applicability of three methods as Fourier number and thermal structure factor were varied and in detail explained the sources that introduce error in the CTF solutions. The results show that the calculation error of SS and DRF methods becomes increasing as the reciprocal of the product of Fourier number and thermal structure factor becomes increasing. The maximal error reaches17.34%and16.83%(single-layered slab),38.7%and-17.49%(three-layered slab),81.61%and-72.50%(six-layered slab). However, the absolution value of the calculation error of FDR method always remains within0.6%no matter how Fourier number and thermal structure factor are varied. Thus, FDR method is more robust and reliable than SS and DRF methods. And it is more practical to calculate CTF coefficients and may be a better choice to calculate the cooling/heating loads for building structures for the architect/designer.
     As above-ground components of the building thermal fabric become more energy efficient, the heat transfer between the building and the ground becomes relatively more important and can no longer be neglected. Thus, it is necessary to design and analyze adequately the ground-coupled heat transfer problems. Most of the former calculation methods are based on conventional numerical solutions such as finite difference, finite element or finite volume technique. These methods are based on the mesh or element. Therefore, it is very complex and difficult to apply and program. To overcome the problems, in this dissertation, the element-free Galerkin method (EFGM) was introduced in chapter3. In the EFGM, the construction of the approximation requires only nodal data—no element structure is needed. The numerical integration of the Galerkin weak form needs only simple integration cells—no element connectivity is needed. The EFGM requires no postprocessing for the output of field variables which are derivatives of the primary-dependent variables since these quantities are already very smooth.
     In this dissertation, the EFGM was utilized to cope with the complex two-dimensional ground-coupled heat transfer problems. The energy status and heat transfer characteristics of underground structures were analyzed and investigated in detail. They can be used as a reference for the engineer and designer. The work and main conclusions of this dissertation are as follows:
     1. In chpter3. firstly, the fundamental principles of the moving least square approximation, which was employed for the construction of the shape function in the EFGM. were introduced and derived in detail mathematically. Secondly, the selection principles of both weight function and domain of influence were discussed. The penalty function and Lagrange multiplier techniques were used to enforce the essential boundary conditions due to their simplicity. A fast algorithmic of the shape function and the derivative was introduced. Thirdly, the discretization of the governing equations by EFGM using both penalty function and Lagrange multiplier techniques was derived from the variational principle. Finally, Gauss-Legendre integration method was used to compute the integration of the Galerkin weak form. The process of the EFGM program was interpreted. Based on the MATLAB work desktop, the EFGM program for the ground-coupled heat transfer problems was developed.
     2. The effects of weight functions and the scaling parameter on the accuracy and convergence rate of the EFGM were discussed in detail by comparison with the analytical solutions of several thermal examples. The results show that the EFGM has very high accuracy and convergence rate. The quartic spline weight function is the most appropriate for heat conduction problems. When an appropriate penalty parameter values, the penalty function method has almost given the same accuracy as the Lagrange multiplier method. In the unsteady analysis, the CPU time of the penalty function method is less than the Lagrange multiplier method. When the scaling parameter increases, no matter what kind of weight function, the CPU time has increased substantially.
     3. The heat transfer model of underground structures involves the wall, floor, roof, foundation, footing, gravel sand and the soil layer. The influence of the water table line and thermal insulations on energy consumption of underground structures is taken into consideration.
     4. Based on the definition of basic distance of nodes, zone uniform distributing node method is put forward for generating discrete nodes in the EFGM.
     5. In the steady-state analysis, the sensitivity analyses of the water table, far field boundary, soil thermal conductivity, outdoor surface wind speed and distance of the roof from the ground surface were carried out. The relationship between energy consumption of underground structures and correlative parameters was investigated in detail. Furthermore, the relationship between energy consumption of underground structures and insulation thickness, length and layout of the location was investigated in detail.
     6. In order to obtain initial conditions in the unsteady analysis, three cycles pre-calculation method was proposed. The third cycle quasi-steady distribution of temperature field was taken as initial conditions. The results show that this method is correct and reasonable.
     7. In the unsteady analysis, parameter sensitivity investigations show that indoor energy consumption of underground structures is very sensitive to the soil thermal conductivity. Therefore, the soil thermal conductivity must be determined cautiously.
     8. In the unsteady analysis, due to insulation, the absolute value of the amplitude and mean of the floor, wall and roof heat flux significantly decreased, and the time delay substantially longer.
     9. The amplitude of1year period harmonic is highest and the second is1day period in Beijing. Sinusoidal temperatures are all attenuated by the soil layer, especially for the shorter period and smaller amplitude waves. The deeper underground structure locates, the bigger the level of the attenuation is.
