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.
Claims12
A process for heating said process comprising evaporating a composition comprising a refrigerant consisting of 1,1,1,4,4,4-hexafluoro-2-butene and thereafter condensing said composition in the vicinity of a body to be heated.
A method for producing heating in a heat pump apparatus, said method comprising introducing a 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 heat transfer fluid composition comprising a refrigerant consisting of 1,1,1,4,4,4-hexafluoro-2-butene.
A method for reducing the GWP of an original refrigerant in a 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 consisting of 1,1,1,4,4,4-hexafluoro-2-butene into said heat pump apparatus.
A method for replacing R11, R123, or R245fa in a heat pump apparatus comprising providing a composition comprising a refrigerant consisting of 1,1,1,4,4,4-hexafluoro-2-butene into said heat pump apparatus.
A heat pump apparatus containing a composition comprising a refrigerant consisting of 1,1,1,4,4,4-hexafluoro-2-butene.
