INLET AIR SUPPLY DEVICE Russian patent published in 2020 - IPC F24F13/06 

FIELD: ventilation.

SUBSTANCE: invention relates to ventilation and air conditioning equipment and can be used to supply inlet air to rooms for various purposes. In the invention, improvement of manufacturability with provision of the jet flow high range and low aerodynamic resistance is achieved by the fact that in the supply air supply device, containing vertically oriented branch pipe and elastic threads with possibility of fixing along perimeter, ends of which are located below branch pipe end, wherein nozzle (1) is made cylindrical, with external flanging (2) on lower end, in which uniformly along perimeter there are holes (3) on number of threads (4), wherein the latter are double-ended and passed through holes (3) such that one end of each thread (4) is fixed in corresponding hole (3) by means of end assembly (5), and free end of thread (4) is located below end with flanging (2).

EFFECT: technical result of invention is creation of version of design of device for supply of fresh air, having high manufacturability while ensuring high range of supply jet and low aerodynamic resistance.
