Abstract: A cooling element with a sorption agent, that under vacuum can sorb a vapor-like working agent that evaporates from a liquid working agent in an evaporator and with a regulator organ in a working agent vapor channel between the sorption agent and the evaporator, wherein the entire cooling element is hermetically enclosed by a gas-tight multi-layer film, the multi-layer film has a flexible construction and is under vacuum so encloses the regulator organ, the working agent vapor channel and the evaporator, that the evaporator and the working agent vapor channel remain flexible and the working agent vapor can flow to the sorption agent only through the regulator organ.

Abstract: A cooling element with a sorbent material (4) which in vacuo can sorb a vaporous working medium that evaporates from a fluid working medium in an evaporator (29) and with a shut-off means which, up to the moment at which the cooling process is initiated, prevents the working medium vapor from flowing into the sorbent material (4), with the sorbent material (4) being sealed into a sorbent-containing pouch (22) which comprises a multilayer sheeting material which in turn comprises at least one metallic layer or one metallized layer.
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.
