Title:

SYSTEM AND METHOD FOR AIR-CONDITIONING AN AIRCRAFT CABIN

Document Type and Number:

WIPO Patent Application WO/2010/012415

Kind Code:

A4

Abstract:

The invention relates to a system (10) for air-conditioning an aircraft cabin (12), said system comprising 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 used air from a first aircraft cabin region (12a) and is connected to the central mixer (16) in order to guide the used air from the first aircraft cabin region (12a) into the central mixer (16). A second recirculation system (24) is designed to remove used air from a second aircraft cabin region (12b) and is connected to a local mixer (20, 22) in order to guide the used 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) during the normal operation of the air-conditioning system (10) in such a way that the second recirculation system (24) removes a pre-defined 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 pre-defined 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).
