AIR DUCT NETWORK ELEMENT Russian patent published in 2020 - IPC F24F13/02 

FIELD: heating.

SUBSTANCE: invention relates to air heating, ventilation and air conditioning systems and can be used for flow discharge in air ducts of these systems. Air duct system element comprises rectangular cross-section barrel and branch with rectilinear walls and possibility of arrangement on inner surface, on part of its length, starting from flow inlet into branch, near downstream in shaft of two walls of branch, smaller sides of which are oriented across flow in barrel, guide element with a curvilinear surface facing the flow to provide a continuous flow from the barrel into the branch, wherein branch wall (1) on a part of its length, starting from the flow inlet into branch (1), closer along flow direction in barrel (2) of two walls of branch (1), smaller sides of which are oriented across flow in barrel (2), is shaped, to form recess (3) on outer wall side of branch (1) and guide projection (4) with surface of curvilinear shape on inner side of branch wall (1). Surface of the curvilinear shape faces the flow to ensure continuous flow entry from barrel (2) into branch (1).

EFFECT: technical result is simplification of design while providing low noise level and low aerodynamic resistance to air flow in branch.
