Device for the Combined Reduction of the Carbon Dioxide and Water or Moisture Content, Motor Vehicle, and Method

A device for combined reduction of a carbon dioxide and water content in an enclosed air volume, the device comprising:

• a first sorption unit configured to sorb carbon dioxide and water;
• a second sorption unit configured to sorb carbon dioxide and water;
• wherein the first sorption unit and the second sorption unit each comprise a plurality of sorbents;
• wherein the first sorption unit and the second sorption unit each are configured to be transferred from a sorption mode into a desorption mode and from the desorption mode into the sorption mode, wherein, in the sorption mode, the first sorption unit and the second sorption unit each sorb carbon dioxide and water from a raw air of the enclosed air volume, and wherein, in the desorption mode, the first sorption unit and the second desorption unit each desorb carbon dioxide and water to a supplied regeneration air;
• an air distribution device configured to switch the first sorption unit and the second sorption unit, as a function of the carbon dioxide and water content in the enclosed air volume, alternately from the sorption mode into the desorption mode and from the desorption mode into the sorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in the sorption mode while the other one of the first and second sorption units is in the desorption mode.
