Definitions
- the present invention relates to a cryogenic refrigeration device and method.
- the invention more particularly relates to a cryogenic refrigeration device for transferring heat from a cold source to a hot source via a working fluid circulating in a closed working circuit, the working circuit comprising in series: a portion of compression, a cooling portion, a detent portion and a warming portion.
- the cold source may be, for example, liquid nitrogen to be cooled and the hot source of water or air.
- Refrigerators known to cool superconducting elements generally use a reverse Brayton cycle. These known refrigerators use a screw-lubricated compressor, a countercurrent plate heat exchanger and an expansion turbine.
- US-3,494,145 discloses a refrigeration system using geared couplings requiring oil bearings. This type of device uses rotating joints such as mechanical seals between the working gas and the gear housing and oil bearings. This architecture increases the risk of leakage of the working gas and the possible pollution of the working gas by the oil. This system also relates to a low speed type motor.
- US-4,984,432 discloses a refrigeration system using liquid ring type compressors or turbines operating with a low speed motor using conventional bearings such as ball bearings. This technology concerns volumetric compressors and turbines.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the invention proposes a cryogenic refrigeration device for transferring heat from a cold source to a hot source via a working fluid circulating in a closed working circuit, the working circuit comprising in series: a substantially isothermal compression portion of the fluid, a substantially isobaric cooling portion of the fluid, a substantially isothermal expansion portion of the fluid and a substantially isobaric heating portion of the fluid, the compression portion of the work circuit comprising at least two compressors arranged in a series and at least one compressed fluid cooling exchanger disposed at the outlet of each compressor, the expansion portion of the working circuit comprising at least one expansion turbine and at least one expanded fluid heating exchanger, the compressors and the or the expansion turbines being driven by at least one engine said to high fast sse comprising an output shaft whose one end carries and rotates by direct coupling a first compressor and the other end carries and rotates by direct coupling a second compressor or an expansion turbine.
- embodiments make it possible to obtain a system without oil pollution and without contact. Indeed, the combination of centrifugal compressors, centripetal turbines and bearings according to the invention reduces or eliminates any contact with the fixed parts and the rotating parts. This avoids any risk of leakage.

- the exchangers 2, 4, 6 may be distinct or consist of separate portions of the same exchanger in heat exchange with the hot source 1.
- the refrigerator comprises several motors (70 see Figure 2) said high speed.
- high speed motor is usually meant engines whose rotational speed allows direct coupling with a centrifugal compression stage or a centripetal expansion stage.
- High speed motors 70 preferably use magnetic or dynamic gas bearings 171 (FIG. Figure 2).
- a high speed motor typically rotates at a rotational speed of 10,000 rpm or several tens of thousands of revolutions per minute.
- a low-speed motor runs rather with a speed of a few thousand revolutions per minute.
- the refrigerator Downstream of the compression portion comprising the compressors in series, the refrigerator comprises a heat exchanger 8 preferably of plate type against the current separating the elements at room temperature (in the upper part of the circuit 200 shown in FIG. cryogenic temperature elements (in the lower part of the circuit 200).
- the fluid is cool (corresponding to area D of Figure 3).
- the cooling of the gas from the ambient temperature to the cryogenic temperature is carried out by countercurrent exchange with the same gas working gas at cryogenic temperature which returns from the expansion portion after heat exchange with the cold source 15.
- the circuit Downstream of this cooling portion constituted by the plate heat exchanger 8, the circuit comprises one or more turbines 9, 11, 13 of expansion, preferably centripetal type, arranged in series.

- the ratio between the number of compression stage (compressors) and the number of expansion stages (turbines) is a function of the target cold temperature. For example, for a refrigerator whose cold source is 273 K, the number of compression stage will be substantially equal to the number of stage of relaxation. For a refrigerator with a cold source of 65 K, the number of compression stages is approximately 3 times greater than the number of stages of expansion.
