Reverse Brayton cryocooler is a closed cycle gas refrigeration machine that produces cryogenic cooling by operating the Brayton thermodynamic cycle in the reverse direction. A gaseous working fluid, commonly helium, neon or a defined gas mixture, is compressed, cooled against the surroundings, precooled in a recuperative heat exchanger and expanded nearly isentropically through a turboexpander. Expansion reduces the gas temperature and produces mechanical work, after which…
