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. beverage) operating medium so that during the adsorption phase, the heat exchanger does not come into contact with the downwardly growing solidifying layer of operating medium, and also so that the liquid operating medium below the solidifying layer transfers the heat adsorbed by the heat exchanger, to the solidified layer of operating medium. Thus, with the cooling container of the present invention, the heat exchanger and liquid (e.g. beverage) passing therethrough are prevented from ever being exposed to temperatures below freezing. Consequently, ice formation within the heat exchanger itself is prevented using a very simply highly effective temperature control mechanism.
