FIELD: ventilation.SUBSTANCE: invention relates to ventilation equipment and can be used in systems of ventilation, air heating and room air conditioning. In panel air distributor comprizing outer perforated plate, forming outer air-distributing surface of air distributor and inner perforated sheet with coefficients effective cross-section from 0.2 to 0.5, installed mutually parallel relative to each other at a distance not exceeding of one diameter of perforated hole, as well as with mutually shifted axes of perforated holes, additionally from the side of inner perforated sheet static pressure chamber is installed with a flat bottom, parallel to inner perforated sheet and located at a distance from inner perforated sheet, equal to, at least, three diameters of one hole of perforation of inner perforated sheet, at that in the center of the static pressure chamber bottom there is connection, cross-section area of which is equal to from 0.15 to 0.3 area of the external perforated air-distribution surface.EFFECT: technical result is formation of turbulent rapidly damping fan-shaped plenum air flow, propagating with high damping rate of speeds and temperatures along aerodynamic axis of air distributor, with opening angle of flow from 70 to 180°.1 cl, 3 dwg |
