A method for generating refrigeration, especially over a wide temperature range including cryogenic temperatures, wherein a non-toxic, non-flammable and low or non-ozone-depleting mixture is formed from defined components and maintained in variable load form through compression, cooling, expansion and warming steps in a refrigeration cycle.
1. A refrigerant mixture which is non-toxic, non-flammable and low-ozone-depleting consisting solely of fluorocarbons wherein the components and their concentrations which make up the refrigerant mixture are such as to form a variable load refrigerant mixture, wherein each of the components of the mixture has a normal boiling point which differs by at least 20 degrees Kelvin from the normal boiling point of each of the other components of the refrigerant mixture, and wherein the normal boiling point of the highest boiling component of the refrigerant mix...
