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.

Abstract: A sorption cooling apparatus for cooling a thermally insulated cooling container 1, with a sorber container 5 containing a sorber material 7 which, during a sorption phase, sorbs a working fluid which evaporates in an evaporator 2 that is disposed in the interior chamber of cooling container 1 and with a valve 4 between sorber container 5 and evaporator 2, which valve can be shut off and which can stop the flow of the working fluid steam, with an evaporator blower 12 being disposed along evaporator 2, which evaporator blower passes an air stream over the evaporator, and with a sorber blower 10 being disposed along sorber container 5, which sorber blower can circulate air around the container containing the sorbent material.

Abstract: Adsorption cooling apparatus with an intermittently heated adsorbent container (12) containing an adsorbent (19) that exothermically adsorbs a working medium during an adsorption phase and again desorbs at higher temperatures while heat is added during a subsequent desorption phase, and with a condenser (4) that leads condensed working medium through a connection line (10) into the evaporator (4) which is in turn connected with the adsorbent through a working medium vapor line (9), wherein the condenser (4) is coupled to a buffer reservoir (14) that buffers at least a part of the condensation heat of the working medium vapor and that also can again dissipate the stored heat into the surroundings even during the adsorption phase.

Abstract: An ice maker utilizing the sorption principle having an air tight sorption container which stores a solid sorption medium. 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: Sorption cooling system of the present invention comprises a transportable cooling unit and a stationary charging (i.e. desorption) station. The transportable cooling unit includes an adsorption container containing an adsorption medium, a cooling container containing a liquid operating medium, and a heat exchanger contained within the cooling container and being surrounded by the liquid operating medium. An operating medium vapor conduit connects the adsorption container and the cooling container, and includes a shut off device which renders the operating medium vapor conduit selectively closable. The stationary charging station is detachable from the cooling unit, and includes a temperature controlled heating box having an opening for receiving the adsorption medium container of the transportable cooling unit, so that a discharged adsorption medium container can be selectively heated to desorb the operating fluid therefrom to form vapor which is condensed to liquid form and stored in the cooling container.
