FIELD: transport.SUBSTANCE: invention relates to cabin ventilation systems. In case leak in aircraft air conditioning system (16) mixer (24) zone is detected, emergent vent valve (38) is changed to open position, said valve as-closed being intended for prevention of air exchange between aircraft zone (40) adjoining said air mixer (24) and aircraft cabin (12). Air from aircraft zone (40) adjoining the air mixer (24) is fed via emergent vent valve (38) to aircraft cabin (12). Aircraft cabin (12) emergent vent system comprises electronic control unit (14), mixer (24), air conditioning system (16), emergent vent valve (38) and air feeder.EFFECT: efficient ventilation at failure of air conditioning system.12 cl, 3 dwg |
