Аннотация: Представлен вычислительный комплекс TEPL, предназначенный для теплотехнического расчета строительных конструкций на основе численного решения дифференциального уравнения трехмерной стационарной теплопроводности. Дискретизация указанного уравнения для численного решения осуществлялась одним из вариантов метода взвешенных невязок - методом контрольного объема. Разработанный комплекс позволяет определить величины сопротивления теплопередаче конструкции, получить картину распределения температур в конструкции. Приведены примеры использования вычислительного комплекса для решения конкретных практических задач.
It is well-known that the problem of economy of energy resources is very actual today. The economy of fuel and energy resources in buildings can be achieved by improving their thermal protection by reducing heat loss through the building envelope. The absence in today's practice of designing buildings a convenient tool for accurate heat engineering calculation does not allow to qualitatively solve the problem of thermal protection of buildings. So, the development of software for the precise and automatic determination of thermal resistance values given on the basis of the calculation of the three-dimensional temperature field is urgent and important problem. The computing program TEPL developed by authors for the thermal analysis of the building structures based on the solution of the equation of steady three-dimensional conductivity is presented in this paper. The numerical solution of differential equations of three-dimensional stationary heat conduction is implemented in the computing program. Discretization of this equation is held by using the method of control volumes. All the geometrical features of analyzed structure, the presence of adjacent elements and inclusions of different types of heat transfer-point (bolts, anchors) and spatial-windows are taken into account when analyzed structure with using this computing program. Thus, heat loss occurring through all elements of structure are accounted and the resulting value of the reduced thermal resistance is the most accurate. The developed program makes it possible to define values of thermal resistance of the building structure, obtain the three-dimensional distribution pattern of temperature in structure. The samples of using program for the solving real practical problems are shown in the paper.
