Abstract:
A method for providing low temperature refrigeration to a use point comprising:(A) compressing refrigerant fluid comprising neon to produce compressed neon refrigerant fluid, and passing the compressed neon refrigerant fluid to a sealed turboexpander/loader; (B) expanding the compressed neon refrigerant fluid by passage through the turboexpander of the sealed turboexpander/loader to produce refrigeration bearing neon refrigerant fluid; (C) warming the refrigeration bearing neon refrigerant fluid by indirect heat exchange with heat transfer fluid to produce cooled heat transfer fluid having low temperature refrigeration wherein the heat transfer fluid is increased in pressure prior to the heat exchange with the refrigeration bearing neon refrigerant fluid; and (D) passing the cooled heat transfer fluid to a use point and providing low temperature refrigeration to the use point.
