Title of the articleEvaluation and regulation of water vapor condensation in enclosing structures.
Abstract.problem statement. It is known that the resistance to vapor permeability of material layers and their combination change the patterns of water vapor condensation in enclosing structures. The purpose of the study is to establish the features of a constructive solution for the temperature formation at the beginning of condensation of enclosing structures and to estimate the duration of condensation in the given climate. A correlation has been established between the proportion of resistance to vapor permeability of the outer layer in the resistance to vapor permeability of the fence as a whole and the temperature of the onset of condensation. A regression equation has been obtained with an approximation reliability of 0.924, which makes it possible to determine D by the parameters of the enclosing structures. It is shown that by changing the parameters of the enclosing structures (D shares) it is possible to regulate them, and, according to the selected value, to design the enclosing structures with the required ratio D. A graphical method has been developed for determining the calendar duration of water vapor condensation in the given climate by comparing the enclosing structures with the annual course of the outdoor air temperature at the construction site. Conclusions. Tools for the design of enclosing structures have been obtained, which will reduce or eliminate the condensation of water vapor in the given climate.
Keywords.enclosing structures, vapor permeability resistance, water vapor condensation, temperature of the onset of condensation, duration of the condensation period.
