Formation of standardized parameters of air in rooms largely depends on climatic features of the area. It is known that at low ambient temperatures (below -15°C) and with standard heating and ventilation systems in rooms, relative air humidity in rooms is about 5% with the minimum of 15%. There is an issue related to determination of the efficiency of heat-and-moisture treatment of air in chambers with irrigated porous packing, which depends on such factors as the geometric shape of channels, hydrodynamic conditions for interaction of the wetted surface of the packing, water film flowing down the surface of the irrigated packing, and air flow moving towards the water film. The present paper presents results of numerical modeling for heat and mass transfer processes using the STAR-CCM+ software package. The k-ε model was used as the turbulence model. Research data can be used to assess quantitative characteristics in contact apparatuses of various configurations.
