    • A refrigerator is provided with a refrigerating unit in the form of an apparatus having at least one pair of containers, where each pair includes a first and a second container (18 and 20, respectively) communicating with each other through a pipe (22). Each container contains a substance which, when being heated, gives off a gaseous working medium and, when being cooled, absorbs the gaseous working medium. The first container (18) is arranged to be heated from the storage compartment (16) of the refrigerator, which compartment thereby is cooled. The second container (20) is provided with a heater (34). Each container is provided with an arrangement for, when need arises, conducting heat away from the respective container, which arrangement includes a cooling circuit (26, 28, 30, 32 and 36, 38, 30, 32, respectively), in which a pump (26, 36) brings a cooling liquid to cool the respective container. The liquid is cooled in a radiator (32) arranged on the refrigerator. The cooling circuit is only partly filled with the cooling liquid so that the liquid returns to a level (40) below the container when the cooling liquid circulation is shut off.
    • 冰箱设置有具有至少一对容器的设备形式的制冷单元,其中每对容器均包括通过管道(22)彼此连通的第一和第二容器(18和20)。 每个容器都含有一种物质,当被加热时,它释放出气态工作介质,并且当被冷却时吸收气态工作介质。 第一容器(18)布置成从冰箱的储藏室(16)加热,从而冷却该隔室。 第二容器(20)设有加热器(34)。 每个容器设置有用于当需要时将热量远离相应容器的装置,该装置包括分别具有冷却回路(26,28,30,32,36,38,30,32)的装置,其中 泵(26,36)带来冷却液体以冷却相应的容器。 液体在布置在冰箱上的散热器(32)中被冷却。 冷却回路仅部分地填充有冷却液,使得当冷却液循环被切断时,液体返回到容器下方的水平面(40)。
