Abstract
An aircraft air-conditioning system is disclosed, which includes at least one heat exchanger to which coolant circulating in a cooling circuit of a cooling system and air are fed. The coolant cools the fed air in the heat exchanger, and the air leaving the heat exchanger enters the aircraft cabin. The coolant of the cooling system is always in the liquid state in the cooling circuit. The liquid coolant can also cool an aircraft seat or a sitting area of the aircraft seat.
Claims14
An aircraft with an air-conditioning system, comprising:
- an aircraft cabin having a plurality of regions and a plurality of seats, including a first region that surrounds a first seat, the first seat sized to accommodate a seated passenger;
- at least one heat transfer device configured as a heat exchanger, which is associated with and cools the first region, and to which is fed a coolant circulating in a cooling circuit of a cooling system, wherein the coolant of the cooling system is always in a liquid state in the cooling circuit;
- a central air-conditioning system operatively connected to the heat exchanger and supplying air to the heat exchanger, wherein the coolant in heat exchanger cools the air, and the air leaving the heat exchanger flows into the aircraft cabin;
- a first seat feed line located within the first seat and connected to the central air-conditioning system, the first seat feed line discharging air from the central air-conditioning system into the first region;
- and
- a heating device that heats the air flowing into the first region, the heating device and the heat exchanger each being located within the first seat feed line,
- wherein a temperature of the discharged air and or an amount of discharged air is configured to be individually adjusted for the first region.
A method for air conditioning of a first region of a plurality of regions in an aircraft cabin, the first region surrounding a first aircraft seat sized to accommodate a seated passenger, the method comprising:
- circulating coolant in a cooling circuit of a cooling system, wherein the coolant of the cooling system is always in a liquid state in the cooling circuit;
- routing the circulating coolant to at least one heat transfer device configured as a heat exchanger, which is associated with the first region;
- and
- supplying air from a central air-conditioning system of the aircraft through a first seat feedline within the first air craft seat, the heat exchanger being located in the first seat feed line such that the air flows through the heat exchanger to cool the air;
- discharging the air cooled by the heat exchanger from the first seat feed line into the first region of the aircraft cabin;
- and
- heating air flowing through the first seat feed line with a heating device located in the first seat feed line,
- wherein a temperature of the discharged air and/or an amount of discharged air configured to be individually adjusted for the first region.
