Abstract
Thermal stability of the enclosure structures is one of the most important objective in the building design. Thermal processes in the wall depend not only on the internal and external air temperature, but also on many other factors. Therefore, complexity of this process make heat conservation in the room to be an actual problem. This paper presents dependence between thermal stability of the enclosure structure and its design. It was shown that thermophysical characteristics of materials directly affect the thermal processes in the wall. For the research, three frequently used types of enclosure structure in Russia were taken. For each wall was found the average temperature and cooling time. As a result, it was found that the higher values of thermal conductivity, specific heat and material density are, the higher average temperature of the wall is.
Highlights
Nowadays the problem of energy efficiency is one of the most discussed issues [1,2,3,4,5]
The purpose of the study is to establish the connection between the energy efficiency of the enclosure structure and its thermal stability
First type of the enclosure structure consists of three layers and has a total thickness 595 mm (Fig.4)
Summary
Nowadays the problem of energy efficiency is one of the most discussed issues [1,2,3,4,5]. Energy consumption for heating buildings is about 40% of all extracted fuel [6]. The main energy task in the construction industry is design of buildings and constructions with effective use of energy [7, 8]. Operating principle of the enclosure structure is to keep heat in the house as long as possible [14,15,16]. For this reason, it is so important that material can be able to resist the stresses caused by change of temperature. These materials show the importance of heat transfer problem in structures
