Özet:

 


Organic Rankine Cycle (ORC) is a
system that uses working fluids with hydrocarbon components instead of water and
generates power from the heat recovery of different heat sources. In this
study, the exergy analysis of a simple ORC, which produces electrical energy
with the help a geothermal source (125°C), was performed. R123, R152a, R245fa
and R600a were determined as the fluids to be used in the Cycle. In this
analysis, which was carried out according to the pinch point temperature
differences (5-20°C) in the evaporator, the exergy performance of the cycle
components was evaluated for the geothermal resource unit flow rate and the
variation of the exergy efficiency of the system was calculated. With the
increase of the pinch point temperature difference in the evaporator, the
decrease of the system’s exergy efficiency became maximal (11.7%) with the use
of R152a as a refrigerant and the loss in the system’s exergy efficiency became
minimal (9.03%) with the use of R123 as a refrigerant.
