Recently, energy need
is exponentially increasing in the world while energy sources are decreasing
rapidly. Therefore, this issue requires energy sources to be used more
efficiently and urges professionals to utilize energy from low temperature
energy sources such as waste heat and low temperature renewable sources. In
this study, energy and exergy analyses of several clean working fluids are
comparatively studied in several organic Rankine cycle configurations. CO2,
N2O, and SF6 fluids are compared with the conventional
R23 in three ORC configurations, namely the basic ORC cycle, regenerative ORC
cycle, and reheat and regenerative ORC cycle, respectively. Effects of various
selected system and environmental parameters on the system performances are
comprehensively investigated. Even though R23 shows the best energy and exergy
performances than those of other investigated working fluids at low-temperature
applications, N2O and CO2 provide a clean solution to
high GWP (global warming potential) R23 with similar performance
characteristics at low and high temperature power generation applications.
