Experimental Methods for Determining the Unsteady-State Heat and Moisture Behavior of Building Enclosing Structures

Improvement of methods for determining heat transfer resistance and unsteady-state heat and moisture regime of enclosing structures is one of the current topics in modern building thermophysics. This article describes methods for determining heat transfer resistance and methods for determining coefficients that influence the temperature and humidity conditions of enclosing structures, regulated by interstate standards. A description of the innovative method of heat transfer resistance allowing to determine the reduced heat transfer resistance of enclosing structures in the summer proposed by V.P. Vavilov, A.V. Grigoriev, A.I. Ivanov is given. and D.A. Nesteruk. A useful model by S.G. Golovnev, K.M. Mozgalev, A.E. Rusanov is presented. The method for increasing thermal homogeneity allowing generating operating conditions when conducting laboratory studies to study the characteristics of vapor permeability of materials is described by G.P. Vasiliev, V.A. Lichman, A.M. Vinogradov, I.A. Vasiliev, V.G. Silaeva. A device by A.S. Petrov is presented, which allows generating operating conditions during laboratory studies to investigate the characteristics of vapor permeability of materials.
