<p>A COOLING METHOD AND ARRANGEMENT A cooling arrangement to be used in liquefying natural gas and in similar applications and having an incorporated cascade circuit with a fractional condensation of a cooling medium and with separation of the phases of the cooling medium, has such a lay-out and is so operated that the warming-up of the expanded cooling medium in a countercurrent evaporative heat exchange and the warming-up of the expanded cooling medium in a countercurrent supercooling heat exchange are in parallel to one another. The separated gaseous phase of the cooling medium is cooled in the countercurrent evaporative heat exchange to be at least partially condensed. Preferably, the countercurrent supercooling heat exchange and the countercurrent evaporative-heat exchange are thermally segregated from one another.</p> |
