FIELD: automotive industry. SUBSTANCE: proposed device includes plenum and exhaust ventilation system. Plenum ventilation system has air intake vent hatch cover, heater and blowing nozzles of windshield, upper and lower parts f car body. Exhaust ventilation system has air intake grills near glazed surfaces communicating with luggage compartment through air ducts. Novelty is that exhaust ventilation system air ducts are placed in communication with air intake of car engine air cleaner through additional air channel. The latter is provided with outer side hole and controlled shutter overlapping its inner or outer hole with constantly open air intake of air cleaner. Definite relationship between sections of holes of air channels provides gauge pressure of air in car body. Proposed system precludes sweating and icing of car window glasses, when warming up at below zero temperatures, without additional power consumption. EFFECT: enhanced efficiency of exhaust ventilation and increased service life of engine air cleaner. 2 cl, 4 dwg
