Abstract

Large cryogenic helium systems created for cryogenic maintenance of objects with superconducting devices work in the mixed modes in most cases. For the characteristic of features of such systems it is thermodynamic correctly defined conception of liquefier, refrigerator and mixed operating modes. Some examples of definition of working zone on the characteristic of cryogenic helium plant are resulted. Meeting difficulties on last stage for cooling of cryogenic helium systems together with cryostatting objects are marked.
