An air-conditioning system and associated method for air-conditioning an aircraft cabin including a first zone and a second zone of variable length and at least one intermediate zone is provided. The intermediate zone is selectively associated with the first zone or the second zone. Air at a first set temperature is supplied to the first zone, and air at a second set temperature is supplied to the second zone. Likewise, air at a third set temperature is supplied to the intermediate zone. A regulating device regulates the third set temperature such that if the intermediate zone is associated with the first zone, the third set temperature corresponds substantially to the first set temperature; but if the intermediate zone is associated with the second zone, the third set temperature.
