文摘
- •
Performance of the combined flash-binary geothermal cycle is investigated.
- •
Thirty different fluids are screened to find the most suitable ORC working fluid.
- •
Optimum cycle operation conditions presented for geofluids between 150 °C and 250 °C.
- •
Refrigerants are more suitable for the ORC at geothermal sources temperature ≤200 °C.
- •
Hydrocarbons are more suitable for the ORC at geothermal sources temperature >200 °C.
