    Patent number: 8544293
    Abstract: A vacuum sorption apparatus includes a first volume region (1) in which a sorber (2) which periodically sorbs or desorbs a refrigerant and a condenser (3) are located, and a second volume region (4) located below the first, in which an evaporator (5) is located, wherein a separating body (6) is located above the evaporator (5) to minimize a free surface area of the liquid refrigerant. The separating body (6) is configured to be vertically movable to compensate for different filling level heights of the refrigerant.
