FIELD: heating systems.
SUBSTANCE: invention refers to ventilation systems of rooms, and namely to natural plenum ventilation devices. Device consists of an air-intake branch pipe to be installed in the building wall opening and closed with an intake grid on the external edge. Device is equipped with an adjustable damper and filter. Device is equipped with the air pipeline connected to the air-intake branch pipe, and that air pipeline is installed along inner side of the building wall and located near the heating radiator or at least partially after the heating radiator. In the wall of the additional air pipeline there made is at least one air exhaust window or perforation supplying the air flow to the radiator, and adjustable shutter and filter is located in the additional air pipeline. In addition, the device can include a noise absorber. The latter shall be preferably installed in the additional air pipeline, and namely before adjustable shutter and filter as to air flow. Labyrinth-shaped noise absorber is preferable as well.
EFFECT: providing the possibility of heating the inlet air owing to air flow supply to the heating radiator.
