Abstract
The article is devoted to decision of actual task of air distribution efficiency increasing due to swirl and spread air jets to provide normative air parameters in the production apartments. The mathematical model of air supply with swirl and spread jets in that type of apartments is improved. It is shown that for reaching of air distribution maximal efficiency it is necessary to supply air by jets, that intensively extinct before entering into a working area. Results of air flow simulation are presented. The graphical and analytical dependences are shown. Dynamic parameters of air flow that is created due to swirl and spread jets has been determined. Results of experimental investigations of air supply into the room by swirl jets are presented. The results of the theoretical and experimental investigations of dependence of the attenuation coefficients and coefficient of device local resistance from the angle of inclination of the twisting plates are presented. It was established that an increase in the angle results in increase of the attenuation coefficients and in decrease of the resistance coefficient of two-flow air distributor (TFAD). The optimum angle of the plates is determined considering aerodynamic and energy aspects.
