- FIG. 3 shows a schematic and partial view illustrating an example of structure and operation of a cooling machine comprising such a compression device.
- the compression device 18 shown diagrammatically in FIG. 1 comprises two centrifugal compressors 1, 3 (that is to say two compressor wheels) forming two successive compression stages.
- the two compressors 1, 3 are each driven by a motor 5, 6 respective drive (preferably electric).
- the compressors 1, 3 are driven in rotation directly by their motor 5, 6 corresponding.
- the device 18 comprises a gas circuit comprising a first gas inlet pipe 13 to be compressed connected to the inlet of a first compressor 1, for conveying gas to be compressed in the first compressor 1.
- the circuit comprises a second pipe 14 having an upstream end connected to an outlet of said first compressor 1 for evacuating the compressed gas in this last.
- the second pipe 14 has a downstream end connected to an inlet of the second compressor 3, for conveying the gas that has been compressed into the first compressor 1 in the second compressor 3 in order to perform a second compression (a second compression stage).
- the circuit comprises a third cooling pipe 15 having an upstream end connected to the outlet of the first compressor 1 (for example via the second pipe 14) and two second downstream ends respectively connected to the inlets of the two motors 5, 6. that is, for example, the third conduit 15 has a common portion with the second conduit 14.
- the third conduit 15 forms a bypass of the second conduit 14 between the first 1 and second 3 compressors
- This third conduit may therefore be a bypass of the second conduit 14 (and / or a separate conduit).
- the third pipe 15 takes a fraction of the compressed gas for supplying the second compressor 3 to scan (cool) the two motors 5, 6. This fraction can correspond to one and forty percent of the flow rate of gas leaving the first compressor 1.
- the flow of gas in each of the two branches respectively supplying the motors 5, 6 may be regulated by a set of valves 7, 8 (or any other suitable member including a pressure-reducing member such as an orifice, a capillary ).
- valves 7, 8 respectively located in the two parallel branches provide these distributions of compressed cooling gas to the motors 5, 6.
- the third single line can be split. That is to say, two distinct pipe portions 15 are respectively connected to the two parallel branches and the two valves 7, 8 or equivalent. Similarly it is possible to consider a single control valve located in the common portion of the two branches (in the pipe portion between the second pipe 14 and the two parallel branches connected to the motors 5, 6).
- the compressed gas leaving the first compressor 1 is preferably cooled, for example by a first member 2 for cooling the gas such as a heat exchanger in heat exchange with a heat transfer fluid.
- the cooling of the gas intended to supply the motors for their cooling may be provided on the third pipe 15 (between the second pipe 4 and the two parallel branches) and / or downstream (on the parallel branches.)

- the third conduits 11, 12 may also be used if necessary to recover the gas from possible leaks (for example, seals located near the engines, such as rotating joints for example).
- the mechanical power necessary to compress a flow rate of 1.26 kg / s of nitrogen gas initially at a pressure of 5 bar absolute and a temperature of 288 K at a pressure of 18.34 bar absolute is approximately 200 kW (100 kW per motor).

- first compressor 1 having a power of 95 kW and a typical isentropic efficiency of 86%.
- the compressed gas is then cooled in the exchanger 2. As described above, part of the gas is withdrawn via the valves 7 and 8 to cool the motors 5 and 6.
- the main flow (flow) is then compressed again up to a pressure of 18.34 bar absolute in the second centrifugal compression stage 3.
- This second compressor 3 has for example a power of 95 kW and a typical isentropic efficiency of 86 %.
- the gas is cooled in an outlet heat exchanger 4 before being sent to the outlet 20 of the compression device 18.
- On the 100kW of work / power of the motors 5, 6, typically 5% will be transformed into heat (losses of the electric motor and losses by friction of the rotor with the nitrogen) or about 5kW by motor 5, 6.
- a portion of the nitrogen flow at the outlet of the first cooling exchanger 2 is thus sent through a first valve 7 and a first branch 9 to the first engine 5 for cooling.
- the rise in the temperature of the gas through the engine 5 will typically be limited to 30 K (to limit the warming of the engine 5) by controlling the valve 7.
- the nitrogen at 318 K (288K + 30K elevation) will be mixed with the nitrogen coming from the inlet 13 of the compressor 1. This can raising the temperature of the nitrogen at the inlet of the first compression stage 1 to 294.5 K and can cause an increase in the energy consumption of this compression stage 1 by an increase in the volume flow rate.
- a second cooling member 17 may optionally be provided in the circuit for cooling the gas leaving the engines 5, 6 before it returns to the first compressor 1.
- the cooling gas leaving the engine (s) 5, 6 can be cooled through, for example, a heat exchanger 17 before rejoining the main circuit of the compressor 1.
- the efficiency of the device is improved by lowering the temperature of the cooling gas before returning it to the inlet of the compressor 1.

- the mechanical power necessary to compress a flow rate of 1.26 kg / s of nitrogen gas having an initial pressure of 5 bar absolute and a temperature of 288 K to a pressure of 18.34 bar absolute is about 198 kW (98kW for the first engine 5 and 100kW for the second engine 6).
- the nitrogen is compressed up to 8.87 bar absolute in the first centrifugal compression stage 1 having for example a power of 93 kW and a typical isentropic efficiency of 86%. Then the gas is cooled in the exchanger 2. Part of the gas is withdrawn via the valves 7, 8 to cool the engines 5, 6.
- the main flow is then compressed to 18.34 bar absolute in the second centrifugal compression stage 3.
- This second compression stage has for example a power of 95 kW and a typical isentropic efficiency of 86%.
- the gas is cooled in the second heat exchanger 4 before being sent to the outlet 20 of the compression device (here output of the second compressor 3).
- Part of the nitrogen flow at the outlet of the first cooling exchanger 2 will be sent through the first valve 7 and the branch 9 to the engine 5 for cooling.
- the rise in the temperature of the gas through the engine 5 will typically be limited to 30 K (to limit heating of the engine 5) by controlling the valve 7.
- the nitrogen at 288 K will be mixed with the nitrogen from the inlet 13 of the compressor 1. This will not have any consequence on the temperature of the nitrogen at the entrance of the first floor 1 (unlike the previous device). The overall yield is improved.
- the cooled gas used for cooling the motors 5, 6 can be taken at the outlet of a second compression stage and / or subsequent compression stage.
- stages of relaxation can be coupled to at least one of the engines.
- one or more expansion stages can be mounted on the same motor shaft as one or more compressors.
- At least one bypass valve can be mounted on the cooling circuit so as to limit the flow rate through one or more motors.
- the flow of cooling gas to a motor 5, 6 can be adjusted by one or more members 7, 8 expansion.
- This or these members may advantageously be adjustable so as to slave for example the temperature of one or more engines and / or the cooling rate and / or the temperature of the cooling gas.
- these detent members 7, 8 may optionally cool the gas before entering the engine (s).
- valves 7, 8 may be replaced or associated with one or more turbines and / or tubes Ranque (Vortex tube). Similarly these bodies 7, 8 may be located on the pipe 15 between the second pipe 14 and the two parallel branches.
- rotating joints can be used between the motor (s) 5, 6 and the compression stage (s) 1, 3 or the expansion stage (s) the pressure in the engine cavities is close to the lowest pressure of the compressor, ie the inlet pressure 13 of the compressor. This has the effect of lowering the friction losses between the rotor or rotors and the gas because these losses are proportional to the pressure in the motor cavity.
- the compression device 18 can be part of a low temperature refrigeration machine, for example between -100 ° C. and -273 ° C., and comprising a working circuit 10 containing a fluid of work, the work circuit comprising a device 18 for centrifugal compression and a device 19 for cooling and expansion of the compressed gas in the device 18 for compression.
