Abstract: 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.

Abstract: A method and devices for the solidification of aqueous substances by the direct evaporation of water from the substance and the sorption of the water vapor in a sorption agent in a vacuum system, wherein the aqueous substance and the sorption agent are evacuated from the surrounding pressure level to a system pressure of below 5 mbar (absolute) by means of a vacuum pump and the nonsorbable gases thereby suctioned by the vacuum pump are suctioned through the sorption agent. The mass of the used sorption agent is at least half the mass of the water fraction in the substance. The solidification process is realized in less than 2 min, particularly less than 20 sec. The aqueous substance is solidified in a solidification container that can be removed from the vacuum system, the vacuum system is subsequently vented, and the solidified substance removed from the vacuum system together with the solidification container.

A vacuum pump is connected to the sorption container and is operatively coupled to an icing container. The icing container is clamped to a flat sealing surface. The vapor contained in the icing container is removed by the vacuum pump causing a decrease in vapor pressure. An aqueous liquid is fed through a closeable feeding line from a supply container to the icing container so that the aqueous liquid solidifies within the icing container.

Abstract: An evaporative refrigerator or cooler comprising a bundle of spaced, porous walled tubes closed at one of their ends and vented to a vacuum at the other end is disclosed. The tube bundle is surrounded by a water jacket having a hot water inlet distribution manifold and a cooled water outlet through a plenum chamber. In operation, hot water is pumped into the jacket to circulate around the tubes, and when this water meets the vacuum existing inside the tubes, it evaporates thereby cooling the water in the jacket. If cooling proceeds to the point where water penetrating or surrounding all or part of the tubes freezes, operation continues with local sublimation of the ice on the tubes while the circulating water attempts to melt the ice. Under some conditions, both sublimation and evaporation may take place simultaneously in different regions of the device.
