Patent ID: 8215120

Claim:
A process for cooling a storage container for storing a medium, said process comprising: a) directly or indirectly connecting the storage container (S) that is to be cooled to a refrigeration circuit ( 2 - 8 , V, T, a, a′), circulating in said refrigeration circuit a cold medium, which is identical to or different from the medium that is to be stored in the storage container that is to be cooled, c) compressing (V), cooling (E), and expanding (T) said cold medium to produce cold, and d) using at least a partial stream of said cold medium ( 5 , 7 ) for cooling the storage container (S) that is to be cooled, wherein (i) said storage container (S) is directly connected to said refrigeration circuit, and the direct connection of the storage container (S) to the refrigeration circuit ( 2 - 8 , V, T, a, a′) is carried out by sending the cold medium that circulates in the refrigeration circuit through the storage container (S) that is to be cooled, or (ii) said storage container (S) is indirectly connecting to said refrigeration circuit, and the indirect connection of the storage container (S) to the refrigeration circuit ( 2 - 8 , V, T, a, a′) is carried out by the cold medium circulating in the refrigeration circuit releasing (E′) its coldness to an auxiliary refrigeration circuit ( 13 , 14 ) having a further cold medium, and said further cold medium is sent through the storage container (S) that is to be cooled.
