FIELD: gas transfer equipment.
SUBSTANCE: proposed ventilation device contains compartment with centrifugal air exhaust fan, drive gas-turbine engine with internal and external envelopes forming channel for hot air, process hatches on diameter of external envelope, and high-pressure compressor. Drive gas-turbine engine is furnished additionally with air conduit to discharge hot air into atmosphere through one of its open process hatches, using as ejector active air delivered into air conduit along separate pipe from high-pressure compressor.
EFFECT: reduced temperature in compartment of drive gas-turbine engine.
