FIELD: ventilation.
SUBSTANCE: in plenum ventilation device the heating of the supplied air is performed owing to air flow supplied to finned nozzle from material with high heat conductivity, which is fixed on heating radiator above which a screen from heat-insulating plate material is installed with the slots made in it, and finned nozzle elements pass through them. Air flow contacts the earthed electrically conducting surface of air duct and saturates the air with negative ions. The device is also equipped with a tray from stainless material and a condensate discharge pipe.
EFFECT: maintaining serviceability of the device at ambient air temperatures below zero; improving plenum air quality.
