Résumé

Application of hydrocarbon mixtures enables the creation of simple, reliable and durable refrigerating and cryogenic Joule-Thomson microcoolers for the temperature range of -73 to -183 °C. The temperature, thermal, power and hydraulic performances of a series of prototypes are presented. The results of tests demonstrate that small, single stage, sealed, lubricated compressors can be applied to these purposes. The start-up and steady operation hydraulic performance of those machines are quite similar to the performance of domestic refrigerators. The last, together with the fact that in the studied microcoolers the lubricated compressors are used at temperatures down to -183 °C, ensures a large resource of operation. That is just the reason that holds out a hope for prospects in a broad field of applications for the studied prototypes, despite their lower power performances in contrast to gas microcoolers.
