| 摘要 |
The invention relates to working fluids for energy conversion in a thermal ORC process for combined generation of electrical and heat energy. The heat source used is in particular thermal water. The working fluids used are partially or perfluorinated hydrocarbons and/or partially or perfluorinated polyethers and/or partially or perfluorinated ketones. In one embodiment of the invention, the working fluid used is a combination of 1,1,1,3,3-pentafluorobutane and a fluorinated polyether having a molecular weight of 340 and a boiling point of 57°C at 101.3 kPa.
