An air conditioner system for electric motor vehicles reduces the thermal load on the air conditioner system during air conditioning using a desiccant-coated heat exchanger and improves energy efficiency thereof using waste heat obtained while cooling electric devices during regeneration of a desiccant-coated heat exchanger.

A nebulizer system for a motor vehicle may include a tank for a liquid, a nebulizer chamber, and a filter system capable of filtering the liquid contained in the tank for the liquid before it passes into the nebulizer chamber. The nebulizer chamber may have a nebulizer nozzle provided with an acoustic wave output device such that the liquid from the tank forms a mist of droplets of the liquid. The mist is intended to pass into a passenger compartment of the motor vehicle. Additionally, the nebulizer system may have an input module for air. The inlet module may have an air injection volute capable of channeling the air in the direction of the internal volume of the nebulizer chamber.

A vehicle air purification system includes a first flow path which includes a first heating device (130-1), a first adsorption block (140-1), and a first flow path switching mechanism (150-1); and a second flow path that includes a second heating device (130-2), a second adsorption block (140-2), and a second flow path switching mechanism (150-2); and an air distribution mechanism (120) configured to distribute air flowing from the vehicle cabin to the first flow path and the second flow path; and a control device (20). The control device (20) controls components at a timing that can inhibit the flow of air from a flow path on the side where purification target substances to be purified are being desorbed into the vehicle cabin.

A device for reducing a carbon dioxide and water content in an enclosed air volume has first and second sorption units for sorbing carbon dioxide and water. The first and second sorption units can be transferred from a sorption mode into a desorption mode and vice versa. In the sorption mode, the first and second sorption units sorb carbon dioxide and water from raw air of the enclosed air volume. In the desorption mode, the first and second desorption units desorb carbon dioxide and water to supplied regeneration air. An air distribution device can switch the first and second sorption units, based on the carbon dioxide and water content, alternately from sorption mode into desorption mode such that, in at least one operating state of the device, one of the first and second sorption units is in sorption mode while the other is in desorption mode.
