Energy And Exergy Analysis Of An Organic Rankine Cycle Using R-236fa, R-152a, R-143a, R-134a As Refrigerants
ABSTRACT
This study evaluated
the energy and exergy analysis, efficiency and exergy destruction of an Organic
Rankine Cycle model using R-134a, R-143a,R-152a and R-236fa as the working
fluid of the refrigerants. Engineering Equation Solver (EES) software was used
in the process modelling of the evaporator, expander, condenser and pump of the
Organic Rankine Cycle. The result showed that an increase in operating
evaporator pressure results in increasing net output and efficiency for the
refrigerants. The exergy efficiency of the system is greatly enhanced by virtue
of the ORC arrangement to include cooling and heating products. The result also
showed that the maximum exergy efficiencies of 158.83 and 64.2 were as a result
of the working fluid R-143a and R-152a, thus a good criterion for the efficient
performance of the system. Refrigerant R- 143 a and R- 1 52a has higher exergy
destruction hence the high exergy efficiency as a result of lower exergy loss
