Abstract

The present invention relates to fluoroolefin compositions. The fluoroolefin compositions of the present invention are useful as refrigerants or heat transfer fluids and in processes for producing cooling or heat. Additionally, the fluoroolefin compositions of the present invention may be used to replace currently used refrigerant or heat transfer fluid compositions that have higher global warming potential.

First claim

What is claimed is:

1. A refrigerant or heat transfer fluid composition comprising a refrigerant component comprising 2,3,3,3-tetrafluoropropene and at least one compound selected from the group consisting of HFC-254eb, HFC-263fb, and mixtures thereof; and at least one lubricant selected from the group consisting of mineral oils, paraffins, naphthalenes, synthetic paraffins, alkylbenzenes, poly-alpha-olefins, polyalkylene glycols, polyvinyl ethers, polyol esters and mixtures thereof.

2. The composition of claim 1 further comprising an additive selected from the group consisting of anti-wear agents, extreme pressure lubricants, stabilizers, free-radical scavengers, water scavengers, corrosion and oxidation inhibitors, metal surface deactivators, foaming and antifoam control agents, and leak detectants.

3. The composition of claim 1 further comprising at least one ultraviolet fluorescent dye selected from the group consisting of naphthalimides, perylenes, coumarins, anthracenes, phenanthracenes, xanthenes, thioxanthenes, naphthoxanthenes, fluoresceins, and derivatives of said dye and combinations thereof.

4. The compositions of claim 3 further comprising at least one solubilizing agent selected from the group consisting of hydrocarbons, dimethylether, polyoxyalkylene glycol ethers, amides, ketones, nitriles, chlorocarbons, esters, lactones, aryl ethers, fluoroethers, and 1,1,1-trifluoroalkanes.

5. A process for cooling, said process comprising condensing the composition of claim 1 and thereafter evaporating said composition in the vicinity of a body to be cooled.

6. A process for heating said process comprising evaporating the composition of claim 1 and thereafter condensing said composition in the vicinity of a body to be heated.

7. A method for producing heating or cooling in a refrigeration, air-conditioning, or heat pump apparatus, said method comprising introducing a refrigerant or heat transfer fluid composition into said apparatus having (a) a centrifugal compressor; (b) a multi-stage centrifugal compressor, or (c) a single slab/single pass heat exchanger; wherein said refrigerant or heat transfer fluid composition comprises the composition of claim 1 .

8. A method for reducing the GWP of an original refrigerant or heat transfer fluid composition in a refrigeration, air-conditioning or heat pump apparatus, wherein said original refrigerant or heat transfer fluid has a GWP of about 150 or higher; said method comprising introducing a second, lower GWP refrigerant or heat transfer fluid composition of claim 1 into said refrigeration, air-conditioning or heat pump apparatus.

9. The method of claim 8 further comprising removing the original refrigerant or heat transfer fluid composition from said refrigeration, air-conditioning or heat pump apparatus before the second, lower GWP refrigerant or heat transfer fluid is introduced.

10. 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.

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

12. A mobile refrigeration or air-conditioning apparatus containing the composition of claim 1 .

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