  • Patent number: 7213411
    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.

  • Patent number: 5440896
    Abstract: Apparatus for cooling a medium within a container includes a container having a chamber with a medium to be cooled located therein. The container being capable of transferring heat energy from an interior surface of the container wall to an exterior surface. The apparatus also includes an evaporation unit having liquid operating medium which is in contact with the exterior surface of the container and a sorption medium container containing sorption medium coupled to the evaporation unit. The sorption medium unit being capable of adsorbing and desorbing operating medium vapor provided by the operating medium. When the liquid operating medium evaporates and is adsorbed by the sorption medium, additional operating medium evaporates causing the operating medium temperature to decrease.

  • Patent number: 4007601
    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.
