The main issue highlighted in the given paper is deviation of microclimate parameters from regulatory values due to improper distribution of air flows in living rooms of blocks of flats. The present work is aimed at obtaining a working mathematical model of natural ventilation system operation, and its further studying for optimization or modernization. The analysis of regulatory documents, research works of national and foreign scientists, developments in the field of natural ventilation and ventilation of residential buildings in general, as well as specific field experiments describing or mentioning similar problems has been carried out. The author’s mathematical model of air exchange in the living room has been presented and analyzed. The boundary conditions in the mathematical model were set as air flow rate and air temperature, and the temperature on the surface of the heater. The features and patterns of air flow distribution inside the room were determined, obtained as a result of mathematical modeling. The distributions of air velocity in the volume of the room were given. Similar problems were indicated for premises of residential buildings of a different functional purpose. Amendments to the existing standards, as well as technical solutions were proposed.
Key words: air exchange / mathematical modeling / aerodynamics / natural ventilation / residential buildings
