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 consisting of about 30 weight percent to about 90 weight percent HFC-1234yf and about 70 weight percent to about 10 weight percent HFC-134a.

2. The composition of claim 1 , wherein said HFC-1234yf is present at about 40 weight percent to about 90 weight percent.

3. The composition of claim 1 , wherein said HFC-1234yf is present at about 50 weight percent to about 90 weight percent.

4. 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.

5. 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.

6. 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 R134a, R407C, or 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.

7. 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.

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

9. The refrigeration, air-conditioning, or heat pump apparatus of claim 8 , wherein the apparatus is a stationary apparatus.

10. A composition comprising of a refrigerant portion, said refrigerant portion consisting of about 30 weight percent to about 90 weight percent HFC-1234yf and about 70 weight percent to about 10 weight percent HFC-134a and 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.

11. A composition comprising of a refrigerant portion, said refrigerant portion, consisting of about 30 weight percent to about 90 weight percent HFC-1234yf and about 70 weight percent to about 10 weight percent HFC-134a and a stabilizer, water scavenger, or odor masking agent.

12. The composition of claim 11 , wherein said stabilizer is selected from the group consisting of nitromethane, hindered phenols, hydroxylamines, thiols, phosphites and lactones.
