Abstract

This article suggests the solution to the up-to-date task of improving and increasing the energy efficiency of buildings and quality of functioning of systems, controlling boilers and heating devices, by using computer simulation and modelling of heat exchange processes of the building and operation of the heating systems. The authors present proven (checked) mathematical models, applicable for external protections, rooms, heaters, boilers, insulated and non-insulated piping. The authors offer an automated system of computer simulation and modelling, which not only allows us to solve mathematical models, but also to complement them with information from a real object and improve them by introducing corrective factors and coefficients.

Highlights

The "Smart House" systems, aiming at improving energy efficiency, are being developed for more than 10 years in Europe, and new materials are being created to achieve heat and energy conservation [1]
It is worth considering that many of years of research on the territory with gentle climatic conditions may not be applicable in the Russian Federation, where climatic conditions differ and vary in the range from -50 to +50 С
The task of mathematical and computer modelling of non-stationary processes of heat exchange, which will help us to investigate the processes of mixing, convection, radiation and thermal conductivity in pipe railings and piping enclosures, protection enclosures, walls, halls, pipelines, heating systems and boilers, is relevant and of vital importance [2]

Introduction

The "Smart House" systems, aiming at improving energy efficiency, are being developed for more than 10 years in Europe, and new materials are being created to achieve heat and energy conservation [1]. It is worth considering that many of years of research on the territory with gentle climatic conditions may not be applicable in the Russian Federation, where climatic conditions differ and vary in the range from -50 to +50 С In this regard, the task of mathematical and computer modelling of non-stationary processes of heat exchange, which will help us to investigate the processes of mixing, convection, radiation and thermal conductivity in pipe railings and piping enclosures, protection enclosures (protective cover), walls, halls, pipelines, heating systems and boilers, is relevant and of vital importance [2]. The authors make an attempt to describe the system of computer modelling of heat-exchange processes in various media and, under certain conditions, which will help to analyze the heating systems, rooms, buildings and other objects in details
