Turbo-refrigerators Using for Cooling the Cryotherapeutic Units

The Paper is devoted to rationale for using refrigerators, working on air refrigeration machine cycle, for cryostating low-temperature space of cryotherapeutic complexes. The low energy efficiency of cryotherapeutic complexes restricts its extensive practical application. The reason for this energy efficiency is that liquid nitrogen with boiling point 78 K is used for exhausting heat at the level 120 – 140 K. The replacement of nitrogen cooling system by the turbo-refrigerator with operating temperature 140 K reduces the energy consumption to the one procedural cycle from 23 to 5.85 mJ.
