A ventilation and air-conditioning system for a high capacity passenger aircraft having plural passenger decks one above another interconnected by stairways or the like, includes two air recycling units (6, 7) respectively incorporating filter units (61, 71) and blower units (62, 72). The inlets of the air recycling units are respectively connected to used air outlets (60, 70) arranged in an upper cabin (2), while the outlets of the recycling units are respectively connected to two air mixing junctions (9 and 10). The first air mixing junction (9) mixes a recirculation airstream from the first recycling unit (6) with an air-conditioned fresh airstream to provide a first mixed airstream into the upper cabin (2) through an air inlet (93). The second air mixing junction (10) mixes a deck transfer recirculation airstream provided by the second recycling unit (7) with an air-conditioned fresh airstream and directs the resulting second mixed airstream into the main cabin (3) through an air supply inlet (103). Used air is exhausted from the main cabin (3) through exhaust air channels (81, 82) into an exhaust air space (8), from which the air is exhausted overboard from the aircraft.

[ What is claimed is:] [1.] A ventilation and air-conditioning system for a high capacity passenger aircraft having a fuselage, a first deck with a first passenger cabin therein within the fuselage, a second deck with a second passenger cabin therein and being arranged below the first deck within the fuselage, an airspace arranged below the second deck within the fuselage, and an interconnection opening between the first passenger cabin and the second passenger cabin; said ventilation and air-conditioning system comprising:an exhaust valve arranged in the fuselage and selectively communicating the airspace to an external environment outside of the fuselage,an exhaust air channel communicating the second passenger cabin to the airspace,a first air mixing junction having a first recirculated air inlet, a first fresh air inlet, and a first mixed air outlet that is connected for air flow to the first passenger cabin,a second air mixing junction having a second recirculated air inlet, a second fresh air inlet, and a second mixed air outlet that is connected for air flow to the second passenger cabin,a first air recycling unit respectively including at least one first blower unit, at least one first used air inlet connected with the first passenger cabin for air flow therefrom, and at least one first recirculated air outlet connected to said first recirculated air inlet of said first air mixing junction for air flow thereto, anda second air recycling unit respectively including at least one second blower unit, at least one second used air inlet connected with the first passenger cabin for air flow therefrom, and at least one second recirculated air outlet connected to said second recirculated air inlet of said second air mixing junction for air flow thereto,wherein said second blower unit of said second air recycling unit is adapted to be so controlled that a deck transfer air flow rate of used air being removed from the first passenger cabin through said at least one second used air inlet of said second air recycling unit is equal to a first fresh air supply rate of fresh air entering said first fresh air inlet of said first mixing junction.
