A process and an apparatus for converting thermal energy into mechanical energy in a Rankine cycle is provided. The process and apparatus include a working fluid that comprises a fluorinated oxirane. The fluorinated oxirane can contain substantially no hydrogen atoms bonded to carbon atoms and can have from about 4 to about 9 carbon atoms. The process can drive a turbine and, in some embodiments, generate electricity.
An apparatus for heat transfer includes a device and a mechanism for transferring heat to or from the device. The mechanism for transferring heat includes a working fluid that includes a hexafluoropropylene trimer having Structural Formula (1) The hexafluoropropylene trimer having Structural Formula (1) is present in the working fluid in an amount of at least 85% by weight, based on the total weight of hexafluoropropylene trimer in the working fluid.
