Lymarenko O. Heat and mass transfer in ventilated layers of protective of protective structures of buildings and constructions

The thesis is devoted to theoretical and experimental research of heat and mass transfer processes occurring in the protective structures of buildings and constructions, namely: the study of heating processes, elements of ventilated channels; determination of heat loss in these elements; justification of the choice of the method of thermal protection of enclosing structures; development of mathematical models of the heat transfer process and methods for determining the basic technological parameters; development of promising technologies for thermal protection of buildings and power equipment; the development of an integrated method of thermal protection and energy saving of buildings and structures. The processes of heat transfer and moisture penetration in various enclosing structures, both in real locations and specially created laboratory stands, have been experimentally studied. An experimental facility has been developed, which allowed defining the basic laws of heat transfer in vertical ventilated channels, on the basis of which data were obtained that allowed assessment of the heat transfer characteristics of these channels, necessary for technological calculations. A complex mathematical model of the heat-moisture regime of the building was created, as well as the method of managing the energy supply of houses, which makes it possible to determine the main energy characteristics.
