Numerical Modeling of Heat and Mass Transfer Processes in Multilayer Temperature Stratification of Indoor Air

Statement of the problem. The purpose of the scientific article is to develop a computer model of hydro- and thermodynamic processes in a room with a multilayer temperature stratification of air for constructing fields of velocity, temperature and humidity of indoor air under various schemes and modes of operation of the air conditioning system. Results. A system of equations of quasi-linear, inhomogeneous, partial differential equations is proposed, as well as a computer model of heat and mass transfer processes in a room with multilayer temperature stratification of air, reflecting the influence of temperature distribution in humid air in height, taking into account its entropy. Conclusions. The developed computer model allows us to obtain the distribution of velocity, temperature and moisture content of air in a room with a multilayer temperature stratification for various principles of air distribution organization and takes into account the processes of evaporation and condensation on surfaces with low temperatures. This allows us to theoretically justify the choice of rational technical solutions and operating modes of microclimate systems, taking into account the conditions for preventing condensation on the internal surfaces of building and enclosing structures of indoor ice rinks and ice arenas.
