System and method for air-conditioning an aircraft cabin

摘要

A system for air-conditioning an aircraft cabin includes an air conditioning unit connected to a central mixer, a first recirculation system designed to remove exhaust air from a first aircraft cabin region and connected to the central mixer, and a second recirculation system designed to remove exhaust air from a second aircraft cabin region and connected to a local mixer. A control device is designed to control the second recirculation system to reduce an air volume flow being removed from the second aircraft cabin region when shifting from a first operating state (e.g., normal operation) to a second operating state (e.g., defined operating situations such as when quick cooling is desired). The air volume being removed from the first aircraft cabin region may be increased accordingly in the second operating state.

1. A system for air-conditioning an aircraft cabin, the system comprising:
an air conditioning unit connected to a central mixer in order to supply the central mixer with air at a desired low temperature, a first recirculation system which is designed to remove exhaust air from a first aircraft cabin region and is connected to the central mixer in order to lead the exhaust air from the first aircraft cabin region into the central mixer, a second recirculation system which is designed to remove exhaust air from a second aircraft cabin region and is connected to a local mixer in order to lead the exhaust air from the second aircraft cabin region into the local mixer, the local mixer being connected to the central mixer in order to supply mixed air from the central mixer into the local mixer, and a programmable control device which is designed to control the first and the second recirculation systems in a first operating state of the air conditioning system in such a way that the first recirculation system removes a first predefined air volume flow from the first aircraft cabin region and the second recirculation system removes a second predefined air volume flow from the second aircraft cabin region, wherein the control device is also designed to control the first and the second recirculation systems in a second operating state of the air conditioning system in such a way that:
an air volume flow removed from the second aircraft cabin region by the second recirculation system in the second operating state is reduced in relation to the second predefined air volume flow removed from the second aircraft cabin region by the second recirculation system in the first operating state of the air conditioning system, andthe air volume flow removed from the second aircraft cabin region by the second recirculation system in the second operating state is also reduced in relation to an air volume flow removed from the first aircraft cabin region by the first recirculation system in the second operating state wherein in the second operating state, the second recirculation system is controlled to reduce air volume flow removed from the second aircraft region without completely stopping the operation of the second recirculation system.
