In this article the results of air distribution device with opposite non-coaxial air jets interaction and also air distribution device with swirl air jets investigations are presented. Research concerns the air flow velocity and temperature decreasing coefficients determination and also both noise level and aerodynamic resistance coefficient were considered.

W artykule przedstawiono wyniki badań urządzeń do nawiewu powietrza. Badania dotyczą współczynników zmniejszania prędkości oraz temperatury strumieni powietrza, a także hałasu oraz współczynników oporu aerodynamicznego.

Modem air distributive devices allow to form the different types of stream with parameters that can differ and by fading rates. Among the wide variety of air distributor devices, on principle of action will consider a few especially interesting. All transferred methods provide the necessary method of serve of air in every concrete case, what provide the normative parameters of ventilation. The construction of air distributive which will unite all higher marked stream depending on requirements to organization of ventilation is offered.

Results of experimental investigations of air supply into the room by air distribution device with interaction of opposed non-coaxial air jets for creation more intensive turbulization air flow in the room are presented. Experimental investigations in order to composed matrix have been carried out; graphicaI and analytical calculation dependences have been obtained as well 3-factor chart has been designed. Obtained results of these investigations give possibility to realize engineer calculations of air distribution with interaction of opposed non-coaxial air jets.
