BELLOW TYPE AIR DISTRIBUTOR (BTAD) Russian patent published in 2021 - IPC F24F13/06 

FIELD: ventilation and air conditioning technology.

SUBSTANCE: invention relates to ventilation and air conditioning technology and can be used to supply air to rooms and objects for various purposes. The bellows-type plafond air diffuser includes a housing with the possibility of accommodating an associated circular perforated reflector. The distributor body is made in the form of a cylindrical cup with a bottom in the lower part and a lateral elastic corrugated bellows wall. The bottom is made in the form of a round reflector with air outlets. The bellows wall is made with U-shaped or U-shaped transverse corrugations in the profile longitudinal section of the nozzle. The corrugations consist of alternating transverse protrusions and depressions. In the outer recesses, air outlets are made, located at the same distance from each other. The axes of the air outlet openings are located perpendicular to the longitudinal axis of the glass and/or in the walls of the outer protrusions closest to each other. On the side of the outer depressions dividing them, coaxial air outlet openings are made in pairs.

EFFECT: simplification of the design, reduction in overall dimensions while ensuring a high degree of air mixing, as well as expansion of technological capabilities in terms of visual indication of the presence of air flow.
