F25J1/0279 - CPC Classification

Classification description:

Processes or apparatus for liquefying or solidifying gases or gaseous mixtures requiring the use of refrigeration, e.g. of helium or hydrogen Details and kind of the refrigeration system used; Integration with other units or processes; Controlling aspects of the process; Start-up or control of the process; Details of the apparatus used; Details of the refrigerant compression system used Compression of refrigerant or internal recycle fluid, e.g. kind of compressor, accumulator, suction drum etc.

Sub-classes:

F25J1/0281 » {characterised by the type of prime driver, e.g. hot gas expander} 23
F25J1/0285 » {Combination of different types of drivers mechanically coupled to the same refrigerant compressor, possibly split on multiple compressor casings} 13
F25J1/0289 » {Use of different types of prime drivers of at least two refrigerant compressors in a cascade refrigeration system} 12
F25J1/029 » {Mechanically coupling of different refrigerant compressors in a cascade refrigeration system to a common driver} 27
F25J1/0291 » {Refrigerant compression by combined gas compression and liquid pumping} 63
F25J1/0292 » {Refrigerant compression by cold or cryogenic suction of the refrigerant gas} 155
F25J1/0294 » {Multiple compressor casings/strings in parallel, e.g. split arrangement} 82
F25J1/0295 » {Shifting of the compression load between different cooling stages within a refrigerant cycle or within a cascade refrigeration system} 17
F25J1/0296 » {Removal of the heat of compression, e.g. within an inter- or afterstage-cooler against an ambient heat sink} 47
