AIR DISTRIBUTION DEVICE Russian patent published in 2004 - IPC

FIELD: venting and air-conditioning equipment.

SUBSTANCE: air distribution device has cylindrical cellular nozzle connected to air duct through inlet pipe. Nozzle cells are formed as diffusers of rectangular cross-section defined by vertical ribs connected to lower and upper cylinder ends. Vertical rib planes are arranged at a tangent to imaginary cylindrical surface defined by inlet ends of cells inside nozzle. Cylinder with opened upper end is arranged coaxially into nozzle and is spaced a minimal distance from inlet cell orifices. Cylinder with opened upper end may rotate around fixed axis and have two outlet diametrically opposite orifices arranged on side surface thereof. Orifices have deflectors providing rotation of air jets exiting cylinder. Inlet device pipe has contraction insert lower end of which is deepened into cylinder with opened upper end. Ejection openings are cut at upper and of cellular nozzle near area of inlet pipe connection. Ejection openings have shutters for regulation of opened orifice areas.

EFFECT: increased intensity of inlet jets attenuation, decreased temperature difference between room air and inlet jets.
