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.
Claims13
A process to produce cooling, comprising:
- condensing a composition comprising (1) a conventional refrigerant;
- and (2) a fluorinated butene;
- wherein the conventional refrigerant is CFC-114, HFC-245fa or HFC-236fa;
- and thereafter
- evaporating said composition in the vicinity of a body to be cooled;
- wherein said condensing and evaporating takes place in a chiller;
- and wherein said fluorinated butene is selected from the group consisting of FC-1318my, HFC-1327my, HFC-1336yf and mixtures thereof.
A method for replacing an original refrigerant or heat transfer fluid composition with a second refrigerant or heat transfer fluid composition, comprising:
- replacing the original refrigerant or heat transfer fluid with a composition comprising (1) a conventional refrigerant;
- and (2) a fluorinated butene;
- wherein the conventional refrigerant is CFC-114, HFC-245fa or HFC-236fa;
- as the second refrigerant or heat transfer fluid composition;
- wherein said original refrigerant or heat transfer fluid composition comprises CFC-114, HFC-245fa or HFC-236fa;
- and wherein said fluorinated butene is selected from the group consisting of FC-1318my, HFC-1327my, HFC-1336yf and mixtures thereof, wherein the original refrigerant or heat transfer fluid composition and the second refrigerant or heat transfer fluid composition is used in a chiller.
A refrigerant or heat transfer composition comprising (1) a conventional refrigerant;
- and (2) a fluorinated butene;
- wherein the conventional refrigerant is CFC-114, HFC-245fa or HFC-236fa;
- and wherein the fluorinated butene is FC-1318my, HFC-1327my or HFC-1336yf.
