  2. 8
    A method of producing cooling, said method comprising:evaporating said composition of any of claims 1-7 in the vicinity of a body to be cooled and thereafter condensing said composition.
  3. 9
    A method of producing heat, said method comprising:condensing said composition of any of claims 1-7 in the vicinity of a body to be heated and thereafter evaporating said composition.
  4. 10
    A method for replacing a high GWP refrigerant in a refrigeration, air-conditioning, or heat pump apparatus, wherein said high GWP refrigerant is selected from the group consisting of R134a, R22, R123, R1 1 , R245fa, R114, R236fa, R124, R12, R410A, R407C, R413A, R417A, R422A, R422B, R422C and R422D, R423A, R507A, R502, and R404A, said method comprising providing the composition of any of claims 1-7 to said refrigeration, air- conditioning, or heat pump apparatus that uses, used or is designed to use said high GWP refrigerant.
  5. 11
    A method of using the composition of any of claims 1-7 as a heat transfer fluid composition, said process comprising transporting said composition from a heat source to a heat sink.
  6. 12
    A method for making the composition of any of claims 1-7, said method comprising:(i) reclaiming a volume of one or more components of a refrigerant composition from at least one refrigerant container, (ii) removing impurities sufficiently to enable reuse of said one or more of the reclaimed components, (iii) and optionally, combining all or part of said reclaimed volume of components with at least one additional refrigerant composition or component.
  7. 13
    A refrigeration, air-conditioning, or heat pump apparatus containing a composition as claimed in any one of claims 1-7.
