The article is devoted to solving the urgent task of increasing the efficiency of air distribution by swirled-compact air jets to ensure the normative parameters of indoor air. It is shown that in order to achieve maximum efficiency of air distribution it is necessary to provide air supply with air jets, which intensively attenuate before entering the serviced area. The mathematical model of air supply with swirled-compact air jets in a non-stationary mode is improved. Airflow simulation was performed using CFD FLUENT (Ansys FLUENT) software using Spalart-Allmaras turbulence model and the k – ε model. Graphical and analytical dependencies based on the experimental studies are presented. The dynamic parameters of the swirled-compact air jet during its leakage in the alternating mode and the formation of a dynamic indoor climate in the room are determined. The method of complex 4D numerical simulation of air velocities in the room depending on time and coordinates at the same time is developed and the dynamic change of the velocity plot is determined.
