The paper is devoted to control of air flows in premises with heat release sources. The modern numerical methods of heat and air exchange processes studies grounded on the equations of Navier – Stokes were utilized. The design schema of air exchange control that ensured heating of the lower zone of premise in the cold period of the year was accepted. The results of warm air processes numerical modeling in premises with heat sources placed above the level of the floor were presented. Using the inlet spray feeding schema inducing vibratory process, air temperature and velocity fields were given for increasing heat recovery effectiveness. For the first time air relative humidity distribution fields were obtained by a numerical method.
