Compositions comprising a fluoroolefin
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.
1. A composition comprising a refrigerant consisting essentially of HFC-1234yf and HFC-32 and optionally trans-HFC-1234ze, wherein the refrigerant consists essentially of from about 20 weight percent to about 99 weight percent HFC-1234yf.
2. The composition of claim 1 , wherein said refrigerant consists essentially of from about 40 weight percent to about 99 weight percent HFC-1234yf.
3. The composition of claim 2 , wherein said refrigerant consists essentially of from about 40 weight percent to about 99 weight percent HFC-1234yf and from about 1 weight percent to about 60 weight percent HFC-32.
4. The composition of claim 1 , wherein said refrigerant consists essentially of HFC-1234yf, HFC-32, and 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 at least one selected from the group consisting of tracers, UV dyes, compatibilizers, solubilizing agents, corrosion and oxidation inhibitors, stabilizers, water scavengers and odor masking agents.
7. The composition of claim 6 , wherein said stabilizer is selected from the group consisting of nitromethane, hindered phenols, hydroxylamines, thiols, phosphites, and lactones.
8. A method of producing cooling, said method comprising: evaporating the composition of claim 1 in the vicinity of a body to be cooled and thereafter condensing said composition.
9. 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.
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, R410A, R407C, R507A and R404A, said method comprising providing the composition of claim 6 to said refrigeration, air-conditioning, or heat pump apparatus that uses, used or is designed to use said high GWP refrigerant.
11. A method of using the composition of claim 1 as a heat transfer fluid composition, said process comprising transporting said composition from a heat source to a heat sink.
12. A refrigeration, air-conditioning, or heat pump apparatus containing a composition of claim 1 .
13. The apparatus of claim 12 comprising a refrigeration apparatus.
14. The apparatus of claim 12 comprising an air-conditioning apparatus.
15. The apparatus of claim 12 comprising a heat pump apparatus.
16. The composition of claim 1 , wherein said refrigerant consists of HFC-1234yf and HFC-32 and optionally trans-HFC-1234ze, wherein the refrigerant consists of from about 20 weight percent to about 99 weight percent HFC-1234yf.
