BRIEF DESCRIPTION OF THE FIGURES

[0043] The invention is illustrated schematically in the drawing on the basis of embodiments, and will be described schematically and in detail with reference to the drawing.

DETAILED DESCRIPTION

[0045] FIG. 1 shows a schematic illustration of a vehicle 2 designed as a motor vehicle, which has the embodiment of the air conditioning system according to the invention. The air conditioning system, which is passive here, has a cooling unit 4 as a first component, which is arranged on an inner wall of the vehicle 2, wherein this inner wall delimits an interior of the vehicle 2. The cooling unit 4 has multiple rods 6 arranged in parallel to one another, wherein each rod 6 has carrier material and phase change material made from at least one fatty acid, wherein the phase change material is accommodated in the carrier material. These rods 6 are woven into fibers made of composite yarn 8, wherein these fibers of the composite yarn 8 are oriented here perpendicularly to the rods 6 made of carrier and phase change material.

[0046] It is provided that the at least one fatty acid of the rods 6 has a melting temperature or a melting point of 25° C., for example. In the embodiment of the method according to the invention, it is provided that the at least one fatty acid of the cooling unit 4 absorbs heat from the interior and thus cools it down in the case that a temperature in the interior of the vehicle 2 and/or in the surroundings of the vehicle 2 is greater than the melting point. The cooling unit 4 also acts at or on the inner wall as a thermal barrier with respect to the surroundings of the vehicle 2. The cooling unit 4 is also covered using cover material that separates the cooling unit 4 from the interior.

[0047] In addition, the embodiment of the air conditioning system has an air humidifier 10 as a second component, which is connected to a water reservoir 12 or a water container via a water line 14. The air humidifier 10 consists of paper clay and is designed to convey water from the water reservoir 12 due to a capillary action, wherein the interior is humidified with the water by the air humidifier 10. In one embodiment, it is possible that the water reservoir 12 is also used for other applications in the vehicle 2 at the same time. It is thus possible for the water reservoir 12 to be used for wiper water from a windshield wiper system, to collect condensed water from another active air conditioning system, or to collect water from a fuel cell of the vehicle 2.
