ABSTRACT:
Multicomponent refrigerant fluids for generating refrigeration, especially over a wide temperature range including cryogenic temperatures, which are advantageous over conventional refrigerant fluids especially for certain applications, and which are non-toxic, non-flammable and low or non-ozone-depleting and preferably are maintained in variable load form through compression, cooling, expansion and warming steps in a refrigeration cycle.
