Air-conditioning system (10) for aircraft, in particular for commercial aircraft, with a bleed air source (12), a bleed air line (22-30) comprising a main valve (16), and an air-conditioning unit (32), wherein a mass air flow conveyed from the bleed air source (12) through the bleed air line (22-30)
Air-conditioning system (10) for aircraft, in particular for commercial aircraft, with a bleed air source (12), a bleed air line (22-30) comprising a main valve (16), and an air-conditioning unit (32), wherein a mass air flow conveyed from the bleed air source (12) through the bleed air line (22-30) to the air-conditioning unit (32) can be controlled by means of the main valve (16). According to the invention it is envisaged that a by-pass line (36-50, 58, 60) comprising a by-pass valve (34) and by-passing at least a part (22-26, 16) of the bleed air line, is present between the bleed air source (12) and the air-conditioning unit (32).

1. Air-conditioning system (10) for aircraft, in particular for commercial aircraft, with two independent redundant air-conditioning system sections, each section comprising a tapped air source (12),a tapped air line (22-30) comprising a main valve (16), andan air-conditioning unit (32),wherein a ma
1. Air-conditioning system (10) for aircraft, in particular for commercial aircraft, with two independent redundant air-conditioning system sections, each section comprising a tapped air source (12),a tapped air line (22-30) comprising a main valve (16), andan air-conditioning unit (32),wherein a mass air flow conveyed from the tapped air source (12) via the tapped air line (22-30) to the air-conditioning unit (32) can be controlled by means of the main valve (16), characterised in that between the tapped air source (12) and the air-conditioning unit (32) there is provided a by-pass line (36-50, 58, 60) comprising a by-pass valve (34) and by-passing at least a part (22-26, 16) of the tapped air line, the by-pass line (42-50) being part of a second air system that is at least partly independent of the air-conditioning system (10), which by-pass line is designed so that it can be operated to supply the air-conditioning unit with a sufficient mass air flow. 2. Air-conditioning system according to claim 1, characterised in that the tapped air line (22-30) contains an ozone converter (24). 3. Air-conditioning system according to claim 1, characterised in that the design and construction of the by-pass valve (34, 50) differs from that of the first valve (16). 4. Air-conditioning system according to claim 1, characterised in that the by-pass valve (34, 50) comprises a damping control. 5. Air-conditioning system according to claim 1, characterised in that the by-pass valve (34, 50) is an on-off valve. 6. Air-conditioning system according to claim 1, characterised in that the by-pass valve (34, 50) can be controlled by a control unit of the air-conditioning system (10). 7. Air-conditioning system according to claim 1, characterised in that the second air system is a cooled service air system and/or a fuel tank inerting system. 8. Air-conditioning system according to claim 1, characterised in that the tapped air source (12) is an auxiliary turbine (14). 9. Method for air conditioning an aircraft, in particular a commercial aircraft, comprising an air-conditioning system with two independent redundant air-conditioning system comprising the steps: providing a tapped mass air flow;passing the tapped mass air flow via a tapped air line to an air-conditioning unit;passing at least a part of the tapped mass air flow sufficient for supplying the air-conditioning unit to the said air-conditioning unit via a by-pass line in the event of a malfunction of the tapped air line, the by-pass line being part of a second air system that is at least partly independent of the air-conditioning system.
