Advancement of applied thermodynamics made it possible starting in the late 1960’s to tackle the problem of developing a highly-efficient single circuit throttling refrigeration cycle. It was shown by means of the exergy analysis that the Carnot efficiency of the well-known throttling refrigeration cycle may be essentially improved by using multi-component refrigerants (MR). Further, based on both thermodynamics of multi-component mixtures and experimental data on multi-phase vapor-liquid and solid-liquid equilibrium, highly-efficient MRs were proposed for different applications down to cryogenic temperatures. A combination of thermodynamics and technology allows us to design and build highly-reliable cryocoolers which are now commercially-available, based on one-stage oil-lubricated compressors. These low-cost coolers provide refrigeration in the temperature range from 65 K to more than 130 K depending on the MR composition. The development of this technology along with present applications, are discussed.
