Definitions
- the invention relates to a cryogenic refrigeration device.
- the invention more particularly relates to a cryogenic refrigeration device comprising a working circuit for cooling a working fluid circulating in said circuit, the working circuit comprising, arranged in series within a loop: a compression portion, a cooling portion, a valve portion (s), a detent portion, and a warming portion, for subjecting the working fluid to a recuperative-type work cycle comprising compressing and then cooling and then relaxing and warming in order to of a new cycle.
- the invention also relates to a cryogenic gas liquefier comprising such a refrigeration device.
- a concern for the constant improvement of existing cryogenic refrigerators or liquefiers is to increase their service life, reduce the minimum operating temperature, increase their reliability. In particular, it is particularly advantageous to eliminate maintenance operations and to eliminate the use of oils.
- a first known solution consists in using a regenerative thermodynamic cycle of the Stirling or Inc.-Tube type.
- the disadvantages of these regenerative solutions are as follows: These devices have poor performance at temperatures below 30K. This is related to the low heat capacity of the materials constituting the regenerator at this temperature level. In addition, in these solutions, it is relatively difficult to thermally bond the refrigerator to the system to be cooled and the heat removal system.
- Another solution is to use an inverted Brayton type thermodynamic recuperative cycle based on a screw-lubricated compressor, a plate counter-current exchanger and a centripetal expansion turbine.
- This solution however has the disadvantage of using oil to cool and lubricate the compressor. This imposes a de-oiling operation of the cycle gas after compression.
- the life of this type of system is relatively short because of the compressor technology used as well as because of the compressor leaks. This technology also has difficulties to relax a two-phase fluid and the energy efficiency is not optimal.
- the compression ratio achievable per centrifugal compression stage is relatively low because of the low molecular weight of the gases that can be used at cryogenic temperature.
- the manufacturing cost of such turbomachines is also relatively high and centripetal machines used are poorly adapted to relax a two-phase fluid.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the device according to the invention is essentially characterized in that the compression portion comprises at least one linear piston compressor driven by an engine.
- the trigger portion comprises at least one linear piston holder
- the valve portion comprises at least one linear type control valve actuated by a linear motor and driven to supply or extract the working fluid of at least a piston regulator.
- embodiments of the invention may include one or more of the following features:
- the device comprises at least one linear piston holder coupled to the linear motor which drives at least one linear piston compressor, that is to say that at least one linear motor couples at the same time a linear piston holder and a linear piston compressor,
- the device comprises at least one linear type control valve coupled to the linear motor which drives at least one linear piston compressor, that is to say that at least one linear motor couples at the same time a linear piston compressor. and a linear type control valve, the device comprises at least one linear piston holder coupled to a linear alternator separate from the motor of the at least one compressor, that is to say that at least one linear alternator couples a linear piston holder to said alternator,
- the working fluid is cooled to a temperature of between 4K and 200 K
- the compression portion of the working circuit comprises several linear piston compressors,
- the expansion portion of the working circuit comprises a plurality of linear piston holders each associated with a respective linear type regulating valve (9),
- the working circuit comprises a high-pressure line connecting a high-pressure outlet of a compressor to the inlet of a pressure reducer, said high pressure line comprising a check valve system, at least one heat exchanger, compressed gas cooling, and a linear type control valve,
- the working circuit comprises a low pressure line connecting an outlet of a pressure reducer to the inlet of a compressor, said low pressure line comprising, a linear type control valve, at least one heat exchanger gas heating and a check valve system,
- the at least one heat exchanger comprises a countercurrent heat exchanger putting in heat exchange the working fluid flowing in the high and low pressure lines,
- the at least one heat exchanger puts the working fluid in heat exchange with at least one of: water, air, nitrogen, helium, hydrogen, methane , neon, oxygen or argon,
