Abstract

The present invention relates to compositions for use in refrigeration, air-conditioning, and heat pump systems wherein the composition comprises a fluoroolefin and at least one other component. The compositions of the present invention are useful in processes for producing cooling or heat, as heat transfer fluids, foam blowing agents, aerosol propellants, and fire suppression and fire extinguishing agents.

First claim

What is claimed is:

1. A composition comprising a refrigerant mixture, said refrigerant mixture consisting of trans-HFC-1234ze, HFC-32 and HFC-125; wherein said trans-HFC-1234ze is present at about 20 weight percent to about 70 weight percent.

2. The composition of claim 1 , wherein said trans-HFC-1234ze is present at about 40 weight percent to about 70 weight percent.

3. The composition of claim 1 , wherein said trans-HFC-1234ze is present at about 50 weight percent to about 70 weight percent.

4. The composition of claim 1 , selected from the group consisting of:
about 30 weight percent HFC-32, about 50 weight percent HFC-125, and about 20 weight percent trans-HFC-1234ze; and
about 23 weight percent HFC-32, about 25 weight percent HFC-125, and about 52 weight percent trans-HFC-1234ze.

5. The composition of claim 1 , further comprising a lubricant selected from the group consisting of polyol esters, polyalkylene glycols, polyvinyl ethers, mineral oil, alkylbenzenes, synthetic paraffins, synthetic napthenes, and poly(alpha)olefins.

6. The composition of claim 1 , further comprising a stabilizer, water scavenger, or odor masking agent.

7. The composition of claim 1 , wherein said stabilizer is selected from the group consisting of nitromethane, hindered phenols, hydroxylamines, thiols, phosphites and lactones.

8. A composition comprising a refrigerant mixture, said refrigerant mixture consisting of trans-HFC-1234ze, HFC-32, HFC-125 and either or both of HFC-134a and HFC-227ea, wherein said trans-HFC-1234ze is present at about 20 weight percent to about 70 weight percent.

9. A method of producing cooling, said method comprising: evaporating said composition of claim 1 in the vicinity of a body to be cooled and thereafter condensing said composition.

10. A method of producing heat, said method comprising: condensing said composition of claim 1 in the vicinity of a body to be heated and thereafter evaporating said composition.

11. A method for replacing a high GWP refrigerant in a refrigeration, air-conditioning, or heat pump apparatus, wherein said high GWP refrigerant is R410A, said method comprising providing the composition of claim 1 to said refrigeration, air-conditioning, or heat pump apparatus that uses, used or is designed to use said high GWP refrigerant.

12. A method of using the composition of claim 1 as a heat transfer fluid composition, said process comprising comprises transporting said composition from a heat source to a heat sink.

13. A refrigeration, air-conditioning, or heat pump apparatus containing a composition of claim 1 .

14. A method of forming a foam comprising:
a. adding to a foamable composition the composition of claim 1 ; and
b. reacting the foamable composition under conditions effective to form a foam.

15. A process for producing aerosol products comprising the step of adding a composition of claim 1 to active ingredients in an aerosol container, wherein said composition functions as a propellant.
