A system for cooling an aircraft region includes an air-conditioning unit for providing cool air, a circulating air conveying device, and a mixing chamber which is connected to the air conditioning unit via an air distribution line and to which circulating air can be fed by the circulating air conveying device. An inlet line which is connected to an aircraft-side connection for an aircraft-external air unit opens into the air distribution line connecting the air conditioning unit to the mixing chamber. Therefore, air flows from the aircraft-external air unit and air flow from the air-conditioning unit are simultaneously provided to the mixing unit and then to the aircraft region.
