  • Cold cell or cold chamber
    Patent number: 6141982
    Abstract: A cooling cell, cabinet or chamber having hollow walls which have fitting at top and bottom which can be alternatively used as inlet and outlet for the fresh cooling medium and the depleted cooling medium and collected gas. In a first phase the fresh cooling medium is forced into the bottom of the hollow wall surface to drive out collected gas above the lighter phase of the previously used medium whereupon the fillings are functionally switched so that the fresh medium is introduced from above and the heavy phase of the depleted medium is discharged from the bottom to complete displacement of the latent cooling medium.
