Thermal Resistance and Accumulation of Heat by the Wall Construction

Abstract

Nowadays the energy efficiency is one of the main topics in the construction industry and transport infrastructure. Therefore, structural and technological activities are aimed mainly at increasing the wall’s thermal resistance. The object of the study is a multilayer enclosing structure (wall). The goal of the article is the selection of the optimal enclosing structures to increase the thermal stability and energy efficiency of the building. The article shows that the heat accumulation in the wall and its thermal resistance are opposite factors. Results of the study show that the thermal resistance of the wall does not depend on the layers alternation. Stationary and periodic temperature, humidity regimes of the walls depend substantially on the layers alternation. Sufficient thickness of the walls helps to reduce energy consumption for heating of building and structures. Consequently, the savings on energy consumption. The studies were conducted by the methods of thermal engineering.
