Title of the articleChanges of thermophysical characteristics of external fencing constructions under conditions of real temperature-humidity regime
Abstract.Problem statement. In the outer enclosing structures, due to changes in the moisture content of the materials, the thermophysical characteristics change throughout the year. The purpose of the study is to increase the reliability of calculations of heat and moisture transfer through external enclosing structures and their resistance to heat transfer, taking into account the dependence of thermal conductivity on sorption humidity. Results. The obtained results showed that during the operation of buildings the layers of the outer enclosing structure operate under different humidity conditions and the conditions A and B for all layers in one design are not correct. According to the results of calculations, the values of thermal resistance differ from the design value, presented in SP 50.13330.2012, by 1-16 %. Conclusions. The significance of the obtained results for the construction industry is to improve the normative documentation by increasing the accuracy of calculating the thermal conductivity and, consequently, increasing the accuracy of calculating the thermal resistance.
Keywords.thermal conductivity, sorption humidity, operating mode, external enclosing structures, resistance to heat transfer.
