A method of obtaining refrigeration at a cryogenic level comprising a gaseous fluid fed in the form of an incoming stream to sustain a refrigerative load. The incoming stream is stepwise cooled and expanded with liquefaction. The liquid fluid formed is used to sustain a refrigerative load, evaporating as a consequence, and the vapour constitutes a return stream which is adiabatically compressed so as to attain a temperature close to the temperature of the incoming stream before the liquefaction thereof.
A method of obtaining refrigeration at cryogenic level comprising compressing a gaseous fluid constituting an incoming stream, stepwise cooling the incoming stream, expanding the incoming stream with its liquefaction, feeding the liquid fluid so formed to sustain at least one refrigerative load wherein the liquid is transformed into vapour constituting a return stream flowing back from the refrigerative load sustained, and adiabatically compressing the return stream flowing back from the refrigerative load so as to attain a temperature close to the temperature of the incoming stream before the expansion thereof with liquefaction;
