Autor: Igbong, Dodeye
Zdroj: Cleaner Energy Systems; December 2022, Vol. 3 Issue: 1
Abstrakt: •An energy and exergy analysis is perform for combined recompression sCO2-ORC cycle.•Performance investigation of R1234ze(Z), R1234yf and R245fa working fluids in ORC-bottoming cycle is presented.•combined recompression sCO2-ORC cycle has better performance than single sCO2cycle.•27.6% of total inlet exergy is destroyed in the Gas-heater component.
