Study of the temperature and moisture regime of building walls in various construction areas

Abstract

The article is devoted to the problems of assessing the balance of moisture transfer when calculating protection against waterlogging of building envelopes. For the calculation, several localities have been selected in which the wall of a building with given climatic parameters and internal air parameters for a living space were modeled. In order to model protection against waterlogging, 3 cities were chosen: Smolensk, Izhevsk and Dudinka. A calculation to protect the building envelope from waterlogging has been carried out. The values of resistance to vapor permeation and heat transfer of each layer of a multilayer building envelope have been calculated. The complex of maximum humidification was assessed, on the basis of which the values of the temperature of the greatest humidification were determined. The values of the actual resistance to vapor permeation and the required resistance to vapor permeation were calculated relative to the plane. Three examples of possible moisture transfer balance were obtained. It was also determined that the construction of the building wall under study is permitted in Smolensk and Dudinka. The researched wall cannot be used in Izhevsk.
