Abstract:

Utilizing various refrigerants with different boiling points, multicomponent mixed-gases Joule-Thomson refrigerators (MJTRs) are suitable for refrigeration applications at temperatures ranging from liquid nitrogen to the lowest effective refrigeration temperature of the single-stage vapor compression refrigeration system. There are extensive and significant requirements for this refrigeration technology in fields of biomaterials, medicine, energy, material sciences, and even the state security. This paper gives a detailed review of our team's achievements on the MJTR for 20 years, including component selection and thermophysic properties of mixed-refrigerants, recuperator features, cycle configuration optimization, composition shift, as well as developments of -186℃ cryo-chamber and skid-mounted natural gas liquefier.

Key words: low temperature range MJTR, thermophysical properties, recuperator, composition shift, cycle optimization
