Abstract

Method and installation for refrigerating the same application by means of several refrigerators/liquefiers disposed in parallel, the refrigerators/liquefiers in parallel using a working gas of the same nature having a low molar mass, that is to say having a mean total molar mass of less than 10 g/mol such as pure gaseous helium, each refrigerator/liquefier comprising a station for compressing the working gas, a cold box intended to cool the working gas at the output from the compression station, the working gas cooled by each of the respective cold boxes of the refrigerators/liquefiers being put in thermal exchange with the application with a view to supplying cold to the latter, in which a single compression station compresses the working gas for each of the respective separate cold boxes of the refrigerators/liquefiers disposed in parallel, the single compression station comprising only compression machines of the lubricated-screw type and systems for removing oil from the working fluid output from the compression machines, so that the compression machines and the oil-removal systems are shared by the refrigerators/liquefiers disposed in parallel.
