A new compact, low-cost, economically competitive and environmentally friendly cryogenic system for cooling a continuous gas flow down to about 30 K is under developing at the ILK Dresden, reported in this paper. The paper shows thermodynamic calculations of cycles on neon and neon-helium mixtures. The assessment of the degree of thermodynamic perfection of the neon cycles in comparison of neon-helium cycles is provided. The use of neon and neon-helium mixture in cryogenic cycles for cryostatting at a temperature level of 27…63 K will increase the thermodynamic efficiency of the cryogenic system and reduce the energy costs of obtaining cold at this temperature level. A technological chain/process, as well as the main economic indicators of the system under development are presented. The availability of such an innovative refrigeration system can be used in a wide range of cryogenic and cooling applications.
Key words: neon refrigeration unit / neon-helium mixtures / cryostatting
