Development of a model and methods for calculating the humidity regime in enclosing structures

Abstract

The article presents a historical overview of the development of the moisture transfer model, calculation methods, as well as the emergence of rationing for the protection of enclosing structures from waterlogging. In particular, the historical periodization of the development of features and approaches to the formation of methodological concepts in relation to the development of stationary and non-stationary methods for calculating the processes of steam condensation, diffusion and moisture transfer is considered. The article contains information from legal sources on the regulation of technological conditions for the use of methods for calculating the movement of moisture in enclosing structures. The author examines the existing models of visualization of calculated data by means of software. Further prospects for studying the presented calculation methods in the design of the structure and in construction are formed. The scientific novelty of this study lies in the formation of a conceptual innovative approach to the periodization of the development of methodological foundations for the study of stationary and non-stationary methods of calculating moisture transfer systems in Russia over the past century and up to the present time. The review of archival scientific and regulatory documentation made it possible to determine the vector of the emergence and development of the issue of moisture transfer models and methods for calculating the humidity conditions of enclosing structures. The results of the review indicate the great contribution of Russian scientists to the creation of theoretical foundations and the development of methods for calculating the humidity regime of fences. The occurrence of rationing of the humidity regime of external fences has been identified and analyzed. The chronology of the appearance of the model, methods of moisture transfer and rationing of protection against waterlogging of structures are analyzed. The parameters of the basic concepts of the periodization of the formation of the methodology for calculating moisture transfer in Russia since the early 20s of the last century have been investigated. Innovative visualization tools for stationary and non-stationary methods of calculating moisture transfer by means of software are presented.
