THE ANALYSIS OF REFRIGERATION CYCLES IN THE TECHNOLOGIES OF PRODUCING OF NEON AND ITS STABLE ISOTOPES AT T= 28 K

摘要

Comparative analysis of the cycles using neon, hydrogen and helium as working substances has been conducted. The refrigerators combined with technological circuits of the separators have been considered. The circuits, in which the refrigerant is one of the final products in order to reduce the number of compressors, have been proposed. Estimated dependencies to forecast the composition of working substance, when the refrigerant circuit is fed by final product, have been received. Energy characteristics of the series of cycles, which are based on available compressor and vacuum equipment, are presented. Individual cost items have been calculated and the reserves to reduce them are identified.
