Application of mixtures of hydrocarbons as multi-component working substances enables development of simple, reliable and durable Joule-Thomson refrigerators designed for the cooling temperatures within the limits of (–183 ...–73) °С. The temperature, thermal, power and hydraulic parameters of a series of prototypes of the refrigerators developed on the basis of hermetic, small, single stage, lubricated reciprocal compressors mass-producing for various refrigerating sets are reported. The application of the lubricated compressors in the refrigerators down to and including the cooling temperature of –183 °С enables durability of the refrigerators. It has been just this case which offers promise for widespread application of the developed prototypes of the low-temperature equipment incorporating the refrigerators in spite of their slightly lower power efficiency as compared with gas refrigerating machines.
