A system may include a beverage compartment with a beverage positioned therein, a wetted material disposed about the beverage, at least one sorption cartridge, and a vacuum pump. The sorption cartridge may be in communication with the beverage compartment, and the vacuum pump may be in communication with the sorption cartridge to create a vacuum in the sorption cartridge and the beverage compartment, causing water to evaporate from the wetted material and be captured by the sorption cartridge, thereby lowering the temperature of the wetted material and in turn cooling the beverage. In some instances, the sorption cartridge may be detached from the vacuum pump and the beverage compartment to discharge the captured water therein by way of solar energy. In other instances, the sorption cartridge may be in communication with a heater assembly to blow heated air through the sorption cartridge to discharge the captured water therein.

A vehicle refrigerator is disclosed. The vehicle refrigerator may include a body, a refrigerating system and a driving system.
