摘要： 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.

摘要： A method for the pulsating load refrigeration of a component of a Tokamak using a refrigeration device subjecting a working fluid to a working cycle. At least one “periodic and symmetrical” operating mode of the Tokamak includes an operating mode in which plasmas of preset duration Dp are generated periodically with intervals of duration Dnp between two successive plasmas. Dnp=Dp±30%. The cooling device cooling power is increased to a relatively high level in a plasma generation phase and reduced to a relatively low level when the Tokamak is no longer in a plasma generation phase. The refrigerating power variation brings gradual increases and reductions in refrigerating power. The increase in the refrigeration device refrigerating power is triggered in advance, in response to a signal (S) generated during a plasma starting step before the thermal load on the component increases.

摘要： The invention relates to a method for low-temperature cooling/liquefaction of a working fluid, in particular a working fluid including helium or consisting of pure helium by means of a refrigerator/liquefier that includes a working circuit provided with a compressor station and a cold box. The refrigerator/liquefier subjects the working gas within the working circuit to a cycle that includes, in series: compressing the working fluid within the compressor station, cooling and decompressing the working fluid in the cold box, and heating the working fluid with a view to the return thereof to the compressor station. The compressor station includes one or more compression levels, each one using one or more compressors mounted on landings. The method is characterized in that the refrigerator includes a device for injecting a seal gas that is separate from the working fluid on at least one landing of the compressor(s) so as to form a gas seal that guides the working fluid leaks, coming from the working circuit, to an area for recirculating and returning the fluid into the working circuit.
