ThenThe invention relates to a method for filling a forna cryogenic storage medium, in particular cryogenic hydrogen,nprovided storage container, in particular a cryogenic pressure tank of anMotor vehicle, wherein before filling with new, offna large reservoir in the liquidnCondition removed cryogenic storage medium at least a subsetnstill as residual gas in the septic tank / cryo-pressure tankncontained storage medium discharged from the storage containernwhich is further using the refrigeration potentialnof the large storage tank cooled andnthus preconditioned for refilling.nThe residual gas is used to precondition the storage tanknso long in a cycle from the storage tank andnby a the refrigeration potential of the large reservoirnusing heat exchanger in a buffer tanknpassed and compressed out of this by means of a cryopumpnand led back to the storage tank,nuntil this storage container with a view to refillingnwith storage medium from the large storage tanknis sufficiently cooled. |
