Definitions

  • the invention relates to a cryogenic refrigeration device.
  • a concern for the constant improvement of existing cryogenic refrigerators or liquefiers aims to increase their lifespan, decrease 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 Pulse-Tube type.
  • the disadvantages of these regenerative solutions are as follows: These devices have poor performance at temperatures below 30K. This is linked to the low thermal capacity of the materials constituting the regenerator at this temperature level. In addition, in these solutions, it is relatively difficult to thermally link the refrigerator to the system to be cooled as well as to the heat removal system.
  • Another solution consists in using a recuperative thermodynamic cycle of the inverted Brayton type based on a lubricated screw compressor, a counter-current plate exchanger and a centripetal expansion turbine.
  • this solution has the disadvantage of using oil to cool and lubricate the compressor. This requires an operation of oil removal of the cycle gas after compression.
  • the service life of this type of system is relatively short due to the compression technology employed as well as due to leaks at the compressor. This technology also has difficulties in relaxing a two-phase fluid and the energy efficiency is not optimal.
  • Yet another solution consists in using a recuperative thermodynamic cycle of the reverse Turbo-Brayton type based on dry centrifugal compressors, a counter-current plate exchanger and a centripetal expansion turbine (cf. FR2924205A1 ). This solution is however not very suitable for low thermal powers because of the difficulty of miniaturizing the turbomachines used.
  • a cryogenic refrigeration device comprising a working circuit intended to cool a working fluid circulating in said circuit, the working circuit comprising, arranged in series: a compression portion, a cooling portion, an expansion portion and a portion reheating, to subject the working fluid to a recuperative type working cycle comprising compression then cooling then expansion then reheating for a new cycle, in which the compression portion comprises at least one compressor linear piston driven by a linear motor, the expansion portion comprises at least one linear piston holder.
  • the compression ratio achievable by centrifugal compression stage is relatively low due to the low molar mass of the gases usable at cryogenic temperature.
  • the manufacturing cost of such turbomachines is also relatively high and the centripetal machines used are ill-suited to relax a two-phase fluid.
  • An object of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
  • the device according to the invention is defined by claim 1.
  • the compression portion comprises at least one linear piston compressor driven by a linear motor
  • the expansion portion comprises at least one linear piston holder
  • the valve portion (s) comprises at least one linear type control valve actuated by a linear motor and controlled to supply or extract the working fluid from the at least one piston regulator.
  • the nonlimiting exemplary embodiment illustrated in figure 1 is a cryogenic refrigerator, for example having a cold temperature of 77k, capable of liquefying nitrogen at saturation.
  • the purpose of the refrigeration device 100 is preferably to transfer heat from a cold source 13 at low temperature (via a heat exchange with an organ or user 7 to be cooled) to a hot source 15 at higher temperature (for example via a heat exchange with a cooling member 5).
  • the device comprises a working circuit for a working fluid (for example helium).
  • the working circuit forms a loop in which the working fluid circulates in one direction while being subjected to a thermodynamic cycle of the recuperative type.
  • the device may include all or part of the components described below.
  • the device comprises one or more linear motors 1 preferably using flexible bearings 2 (or gas or low friction or magnetic).
  • the bearings shown as an example on the figure 1 are of the flexible bearing type.
  • compressors 3 with piston (s) use for example non-return valves 4 and 14 to communicate with lines 12 high pressure (to discharge compressed fluid) and low pressure 11 (to accommodate expanded fluid in order to return it compress).
  • non-return valves 4 and 14 to communicate with lines 12 high pressure (to discharge compressed fluid) and low pressure 11 (to accommodate expanded fluid in order to return it compress).
  • check valve technologies can be envisaged, for example reed valves.
  • any other type of member making it possible to prevent the return of the compressed fluid in the opposite direction in the circuit can be envisaged.
  • the working circuit comprises one or more exchangers 5 provided for removing heat from the compressed gas towards a hot source and arranged at the outlet of the compressor (s) 3.
  • This cooling exchanger puts the working fluid, for example, in heat exchange with a coolant 15.
  • At least one counter-current heat exchanger 6 is provided downstream in the direction of circulation of the working fluid in the circuit on the high pressure line 12.
  • This heat exchanger 6 can separate the relatively high temperature elements from the relatively low temperature elements 6 of the circuit.
  • the circuit then comprises at least one valve 9 operating at low temperature (that is to say between 4 and 200K).
  • This valve 9 is designed to supply and extract the gas from a piston regulator 10 located downstream.
  • This valve 9 can be actuated by a linear motor 8 of technology equivalent to the technology of motor 1 of the compressor.
  • This valve 9 is preferably actuated at the same frequency as the regulator 10, however, its movement is out of phase with respect to the regulator 10 so as to maximize the efficiency of the regulator 10.
  • the piston or regulators 10 operate at low temperature and may or may not be mechanically linked to the motor 1 of the compressor.
  • the gas expanded by the regulator 10 is returned to the compressor 3 via a low pressure line 11 (through the valve 9).
  • One or more heat exchangers 7 are provided to heat the working fluid and thus extract heat from the cold source 13.
  • the expanded fluid passes in particular through the exchanger 6 against the current before returning to the compressor 3 ( via the corresponding valve 4).
  • the operation of this refrigerator 100 can be as follows.
  • the working gas (helium in this example) in the gas phase (for example at 20 ° C.) is compressed through the piston compressor 3 from a low pressure (for example 10 bar) to a high pressure (for example 18 bar).
  • the non-return valves 4, 14 are used to make the compression chamber of the compressor communicate alternately with the low pressure line 11 and the high pressure line 12.
  • the helium is heated at the outlet of the compressor (for example to 110 ° C).
  • the helium is then cooled through a first exchanger 5 using a water flow 15 (or any other suitable cooling agent).
  • the temperature of the helium is reduced to 25 ° C.
  • the helium then passes through the countercurrent exchanger 6, its temperature is lowered, for example to 79K. Downstream, the regulation valve 9 is used to make the expansion valve 10 communicate alternately with the low pressure line 11 and the high pressure line 12.
  • This piston regulator 10 is notably configured to operate with a two-phase or liquid fluid.
  • the expansion work from the regulator 10 can be transferred via the common shaft of the linear motor 1 to the compressor 3.
  • the helium then passes through the reheating exchanger 7 where it cools the cold user member 13 (nitrogen in this example).
  • the cooled nitrogen gas 13 is for example liquefied to saturation by extracting heat from it.
  • the temperature of helium is for example brought to 76 K.
  • the helium then passes again through the countercurrent exchanger 6 where it is heated (for example to 20 ° C).
  • the helium then returns to the compressor 3 to carry out a new identical cycle via the valve 4.
  • the figure 2 illustrates another embodiment of the invention.
  • This example represents a gas liquefier, in particular hydrogen.
  • This liquefier uses the same main elements as those described above.
  • the working gas for example at 20 ° C (in the gas phase) is compressed in two piston compressors 20 and 21 arranged in series.
  • each compressor 20, 21, (via a high pressure line and a valve 14), the gas is cooled by a heat exchanger 22, 23. This hydrogen is then cooled through a first heat exchanger 24 against a current.
  • Part of the flow of cooled gas can be allowed to pass, via a bypass 15 comprising a first linear valve 9, through a first piston regulator 25 so as to extract heat with hydrogen.
  • this first piston 25 regulator can be linked to the first compressor 20 via a linear motor (not shown for the sake of simplification but may be of the same type as that described above). Similarly, the first regulator can be coupled to a separate engine (alternator).
  • the first control valve 9 upstream of the first regulator 25 is preferably actuated via a linear motor (not shown for the sake of simplification but may be of the same type as that described above).
  • the hydrogen (expanded or otherwise) can then be cooled through a second counter-current exchanger 26, and if necessary through a third counter-current exchanger 27.
  • This hydrogen expanded in the first regulator 25 can be returned directly to the first compressor 20 (via the counter-current heat exchanger (s) 24, 26. That is to say that the hydrogen expanded in the first regulator 25 can be returned to the compressors without undergoing a second expansion or cooling.
  • the remaining hydrogen is then expanded in a second linear regulator 28 (via a valve 9 for linear control).
  • the second expander 28 is preferably of the two-phase piston type for extracting heat with hydrogen in order to partially liquefy it.
  • This second expander 28 with piston can be mechanically linked (coupled) to the second compressor 21 (via a linear motor not shown for the sake of simplification as above) or to a separate alternator.
  • the second control valve 9 located upstream of the second regulator 28 can also be actuated by a linear motor (not shown for the sake of simplification).
  • control valves 9 controlling the circulation of the fluid between the regulators 25, 28 and the compressors 20 can if necessary be actuated by a single common actuator.
  • the two-phase mixture obtained after passage through the second regulator 28 can then be sent to a cryogenic separator 29.
  • the gaseous phase of hydrogen is returned to the first compressor 20 through exchangers 27, 26, 24 against the current.
  • the working fluid used can be any other fluid than helium or hydrogen, for example nitrogen, methane, neon, oxygen or argon.
  • the working circuit can thus be of the open or closed type.
