Maintaining optimal thermal conditions is one of the most important requirements for buildings and constructions. For optimal control of the temperature conditions of the object, it is necessary to study the characteristics of thermal processes occurring in multilayer enclosing structures (MES). The processes of heat and mass transfer from one medium to another through the enclosing structure (ES) separating them are possible only if the external and internal sources (sinks) of heat or matter are unequal. In connection with this, the actual problem is evaluation of temperature and humidity stresses of the ES of buildings and constructions at unsteady heat transfer modes. The aim of the research is a numerical analysis of unsteady heat and moisture exchange in the MES based on formalized mathematical models (MM). In this paper, we study the MM of unsteady and steady heat transfer in the MES at various initial (IC) and asymmetric boundary conditions (BC) of the third kind. The thermophysical characteristics in a piecewise homogeneous medium (PHM), having removable discontinuities of the first kind, were specified using the generalized Heaviside function, and the constancy of the IC using the generalized Dirac function.
