A freezing or cooling plant comprises an apparatus having an evaporator chamber. At the lower end the apparatus is connected with a feed conduit for liquid refrigerant and a suction conduit for suctioning refrigerant vapors. Both conduits communicate with a vessel in such a way that liquid refrigerant from the apparatus may flow to the vessel via both the conduits. By heating the apparatus due to washing of the outer surface of the evaporating chamber of the apparatus, only moderate pressure rises will occur in the apparatus since, after the cooling process is stopped, the apparatus will be emptied of liquid refrigerant and during the remaining washing period will contain solely superheated refrigerant vapors. |
