AERATION DEVICE WITH VARIABLE FLOW SECTION FOR NATURAL VENTILATION SYSTEMS AT ARCHITECTURAL MONUMENTS

摘要

FIELD: heating.;SUBSTANCE: aeration device is designed for natural ventilation systems of architectural monuments. The aeration device comprises releasably connected louvre module casing with a louvre grid and valve module casing with at least one damper with the damper suspension unit and the damper deflection angle limiter with a return spring. The damper deflection angle limiter is made as at least one arrester rigidly connected to the rod and controlled by a rope; the rod is set in the guide bushes welded to the valve module casing and the damper suspension unit is fitted by a stopper interacting with the arrester.;EFFECT: increased reliability of temperature-humidity conditions normalisation, elimination of stagnation zones, removal of excessive air from the building inner volume.;4 dwg
