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: A leakage free bushing for placement through a surface of a fitting body. The leakage free bushing has flexible bellows, a moveable sealing element and a stationary sealing seat. The flexible bellows have one end connected to the fitting body in a leakage free manner while its other end is capable of an angular tilt movement with respect to the vertical axis of the flexible bellows. The moveable end of the flexible bellows are covered in order to prevent leakage. The flexible bellows have an actuating knob connected to its outer area which, when rotated, permits mechanical deflection of the bellows. In the inner area of the fitting body at the left of the bellows axis, a transmission assembly is located which transmits the mechanical deflection caused by the actuating knob to the inner space of the fitting body.

Abstract: A sorption container for solid sorption medium, for example, zeolite, consists at least partially of a flexible metal corrugated hose, whose waves are filled on the inside with sorption medium.

Abstract: Disclosed is a cooling container for use in a sorption apparatus. The cooling container is adapted for containing a liquid operating medium, which, during the adsorption phase of operation of the adsorption apparatus, cools off by partial evaporation and solidifies into a solidifying layer starting from the surface of liquid operating medium. In general, the cooling container comprises a vessel and a heat exchanger. The vessel is provided for containing the operating medium, which during the adsorption phase, cools off by partial evaporation and forms the solidifying layer which grows from the surface downwardly into the vessel until the solidifying layer obtains a maximum thickness. The heat exchanger on the other hand is provided for adsorbing heat from a liquid passing through the heat exchanger, and is positioned in the vessel and within the liquid (e.g.

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.
