FIELD: ventilation; air conditioning.
SUBSTANCE: invention relates to ventilation and air conditioning. Disclosed is a ventilation duct with a cross section. The ventilation duct includes the corners formed by the duct walls. The ventilation duct can contain curved stiffeners. The air duct (1) is made with three outwardly convex curved walls (2) and a cross-section in the shape of a Reuleaux triangle (3).
EFFECT: invention simplifies the design and reduces material consumption while ensuring high rigidity of the structure and lower aerodynamic resistance to air flow.
