TOROIDAL AIR DISTRIBUTOR (TAD) Russian patent published in 2020 - IPC F24F13/06 

FIELD: ventilation.

SUBSTANCE: invention relates to ventilation and air conditioning equipment and can be used for distribution of supply air to premises for various purposes. Said result is achieved by the fact that in toroidal air distributor containing corrugated element connected to pair of opposite towards each other channels of identical shape and dimensions for air passage, restricted on the side of inlet of flow by end edges, and possibility of arrangement of inlet opening, and outlet opening with overlapping of the latter, and limiting the ends of each of the channels on the side of outlet of the flow by the edges of the outlet opening, wherein element is made in the form of hollow open corrugated toroidal structure (1) with central opening (2), opposed to inlet (3) and outlet (4) windows, arranged in wall of toroidal structure (1) with formation of pair of opposite to each other corrugated channels (5) of same shape and sizes for air passage, wherein channel (5) ends on the flow inlet side are limited by inlet window (3) edges, and channels (5) ends on the flow outlet side are limited by outlet window (4) edges, wherein the latter is covered by wall section of toroidal structure (1) on the side of central hole (2) or outlet opening (4) is covered by wall section of toroidal structure (1) on opposite side of convex side of toroidal structure (1).

EFFECT: technical result of the invention is the creation of an embodiment of the design of the toroidal air distributor, having a simpler design and lower material capacity while ensuring high rate of attenuation of the flow rate of the supply jet.
