SUPPLY AIR DISTRIBUTION DEVICE (VERSIONS) Russian patent published in 2020 - IPC F24F13/06 

FIELD: ventilation and air conditioning.

SUBSTANCE: invention relates to ventilation and air conditioning equipment and can be used to supply inlet air to rooms and objects for various purposes. In supply air device containing cylindrical housing with inlet and outlet coaxial holes, connected to housing on outlet side diffuser branch pipe with possibility of connection of its larger round base and flow-through diffuser coaxially located in diffuser branch pipe with formation in diffuser branch pipe of annular gap with possibility of its overlapping and conjugation of larger round base of flow diffuser, diffuser is made with opening angle exceeding opening angle of branch pipe, and a large round base interfaced with a large round base of the branch pipe, with formation in the latter of the annular gap narrowed by the side wall of the acute-angled V-shape in the cross-section by the plane in which the branch pipe axis is located. In device for supply of fresh air, comprising cylindrical housing with coaxial inlet and through holes, flow diffuser with round base and possibility of conjugation of the latter, axial arrangement of flow diffuser with formation of annular gap and arrangement of outlet hole, housing is made in the form of a cylinder, in the bases of which there are inlet and through holes respectively, wherein the diffuser is made in the form of a hollow cone coaxially located in the cylinder, evenly along the perimeter of the side wall of which there are holes for air passage, and in the cone base there is an outlet hole, wherein the cylinder base, in which the through hole is located, is conjugated with the cone base with formation in the annular gap cylinder of the acute-angled V-shape in the section by the plane, in which the cylinder axis is located.

EFFECT: design of a design version of a device for distributing supply air, having a simpler process structure while providing high intensity of damping of the speed of the supply jet.
