A system (10) for air-conditioning an aircraft cabin (12) comprises an air conditioning unit (14) connected to a central mixer (16) in order to supply the central mixer (16) with air at a desired low temperature. A first recirculation system (18) is designed to remove exhaust air from a first aircraft cabin region (12a) and is connected to the central mixer (16) in order to lead the exhaust air from the first aircraft cabin region (12a) into the central mixer (16). A second recirculation system (24) is designed to remove exhaust air from a second aircraft cabin region (12b) and is connected to a local mixer (20, 22) in order to lead the exhaust air from the second aircraft cabin (12b) into the local mixer (20, 22). The local mixer (20, 22) is connected to the central mixer (16) in order to supply mixed air from the central mixer (16) into the local mixer (20, 22). A control device (28) is designed to control the second recirculation system (24) in the normal operation of the air conditioning system (10) in such a way that the second recirculation system (24) removes a predefined air volume flow from the second aircraft cabin region (12b). The control device (28) is also designed to control the second recirculation system (24) in defined operating situations of the air conditioning system (10) in such a way that the air volume flow removed from the second aircraft cabin region (12b) by the second recirculation system (24) is reduced in relation to the predefined air volume flow removed from the second aircraft cabin region (12b) by the second recirculation system (24) in the normal operation of the air conditioning system (10). |
