FIELD: heating.SUBSTANCE: wall grid, namely for air passage from air conditioner to outer side, consists of external frame inside which there fixed is a row of parallel deflector plates having essentially concave cross section; plates have at their bottom the drain holes for discharge of rain water to below lying inclined wing that is located between the last lower deflector plate and lower edge of frame; at that, cross section of plates is V-shaped and has external wing that is longer than internal wing and inclined symmetrically relative to internal wing; the above external wing ends with horizontal fold, and plates are assembled so that bottom of above lying plate lies in one plane with horizontal end fold of below lying plate so that two plates form S-shaped air deflection path; at that, the above air is deflected upwards at the outlet by means of two adjacent external wings of two subsequent deflector plates.EFFECT: increasing the wall grid efficiency.10 cl, 3 dwg |
