[ What is claimed:] [1.] A method for generating refrigeration comprising:(A) compressing a variable load refrigerant mixture comprising at least one component from the group consisting of fluorocarbons, hydrofluorocarbons and fluoroethers and at least one component from the group consisting of fluorocarbons, hydrofluorocarbons, hydrochlorofluorocarbons, fluoroethers, atmospheric gases and hydrocarbons to produce a compressed variable load refrigerant mixture;(B) cooling the compressed variable load refrigerant mixture to produce a cooled compressed variable load refrigerant mixture;(C) expanding the cooled, compressed variable load refrigerant mixture and generating refrigeration to produce a lower temperature variable load refrigerant mixture; and(D) warming the lower temperature variable load refrigerant mixture.
