Abstract:
1. Aircraft air-conditioning system which is configured for air-conditioning an aircraft cabin having a plurality of zones, comprising: a first supply line, a first air-conditioning device, a first zone temperature sensor, and a first supply line temperature sensor, which are associated with a first zone of the aircraft cabin, the first supply line supplying air to the first zone, the first air-conditioning device configured for altering a temperature of air flowing into the first zone, the first zone temperature sensor detecting an actual temperature of air in the first zone, and the first supply line temperature sensor detecting an actual temperature of air flowing into the first zone, a second supply line, a second air-conditioning device, a second zone temperature sensor, and a second supply line temperature sensor, which are associated with a second zone of an aircraft cabin, the second supply line supplying air to the second zone, the second air-conditioning device being configured for altering a temperature of air flowing into the second zone, the second zone temperature sensor detecting an actual temperature of air in the second zone, and the second supply line temperature sensor detecting an actual temperature of air flowing into the second zone, an intermediate zone supply line, an intermediate zone air-conditioning device, an intermediate zone supply line temperature sensor, and an intermediate zone temperature sensor, which are associated with an intermediate zone located between the first zone and the second zone and selectively associated with either the first zone or the second zone to vary the length of the corresponding associated zone, the intermediate zone supply line supplying air to the intermediate zone, the intermediate zone air-conditioning device being configured for altering a temperature of air flowing into the first intermediate zone, the intermediate zone supply line temperature sensor detecting an actual temperature of air flowing into the intermediate zone, and the intermediate zone temperature sensor detecting an actual temperature of the air in the intermediate zone, and a regulating device, wherein if the intermediate zone is associated with and adjacent to the first zone, the regulating device regulates a set temperature of the air flowing into the intermediate zone based on the detected actual temperature of the air in the first zone in combination with the detected actual temperature of the air in the intermediate zone, and wherein if the intermediate zone is associated with and adjacent to the second zone, the regulating device regulates a set temperature of the air flowing into the intermediate zone based on the detected actual temperature of the air in the second zone as detected by a second zone temperature sensor in combination with the detected actual temperature of the air in the intermediate zone.
