20130000332 | Method and Equipment for Pulsed Charge Refrigeration - The invention relates to a method and device for pulsed charge refrigeration of a member from a Tokamak. The method uses a refrigeration device that subjects a working fluid such as helium to a work cycle comprising: compression, cooling, and decompression, as well as heat exchange with the member and heating. The refrigeration power produced by the refrigeration device is increased to a relatively high level when the Tokamak is in a plasma generation phase, and the refrigeration power produced by the refrigeration device is decreased to a relatively low level when the Tokamak is no longer in a plasma generation phase. Said method is characterized in that the increase in refrigeration power produced by the refrigeration device is automatically triggered in response to a signal produced during a step for starting plasma in the Tokamak. | 01-03-2013 |
20130014518 | Refrigeration Method and Apparatus with a Pulsating LoadAANM Aigouy; GeraldAACI La Croix De La RochetteAACO FRAAGP Aigouy; Gerald La Croix De La Rochette FRAANM Briend; PierreAACI SeyssinetAACO FRAAGP Briend; Pierre Seyssinet FRAANM Deschildre; CindyAACI SassenageAACO FRAAGP Deschildre; Cindy Sassenage FRAANM Fauve; EricAACI BolleneAACO FRAAGP Fauve; Eric Bollene FRAANM Bernhardt; Jean-MarcAACI La BuisseAACO FRAAGP Bernhardt; Jean-Marc La Buisse FRAANM Delcayre; FranckAACI River Sur FureAACO FRAAGP Delcayre; Franck River Sur Fure FR - A method for the pulsating load refrigeration of a component of a Tokamak, said method using a refrigeration device subjecting a working fluid such as helium to a working cycle, the Tokamak comprising at least one operating mode called “periodic and symmetrical,” according to the method, the refrigerating power produced by the refrigeration device being increased to a relatively high level when the Tokamak is in a plasma generating phase (Dp) whereas the refrigerating power produced by the refrigeration device is reduced to a relatively low level when the Tokamak is no longer in a plasma generating phase (Dnp), characterized in that during the “periodic and symmetrical” operating phase of the Tokamak, the refrigerating power of the refrigeration device is regulated according to a forced variation also of the “periodic and symmetrical” type, that is one wherein the respective durations of generation of a high level of refrigeration and of generation of a low level of refrigerating power differ at most by 30%, and in that the variation in refrigerating power brings about gradual increases and reductions in refrigerating power, and in that the increase in refrigerating power produced by the refrigeration device is triggered in advance, in response to a signal (S) generated during a plasma starting step in the Tokamak, that is before the thermal load on the component increases. | 01-17-2013 |

20130291585 | Installation and Method for Producing Liquid Helium - The invention relates to a method and an installation for producing liquid helium, said installation comprising a cooling/liquefaction device comprising a working circuit that subjects a helium-enriched working fluid to a thermodynamic cycle in order to produce liquid helium, said circuit comprising at least one working fluid compression body and a plurality of heat exchangers. The installation also comprises a plurality of fluid recovery lines having respective upstream ends to be selectively connected to respective reservoirs, and a first collection line having an upstream end connected to the recovery lines and a downstream end connected to a receiving body that can supply the working circuit with a working fluid. The installation is characterized in that it comprises at least one second and one third collection line that each have an upstream end connected to the recovery lines and a downstream end connected to the working circuit, the upstream ends of the second and third collection lines being connected at separate determined positions of the working circuit, that respectively correspond to separate temperature levels of the working fluid in the working circuit. | 11-07-2013 |
