Abstract :
The organic Rankine cycle (ORC) system, which recovers the engine waste heat, can improve the energy utilization of the engine. This paper analyzed basic ORC and superheat ORC using R123 as working fluid, respectively. The results show that superheating the working fluid cannot gain the output power or improve the system efficiency effectively, while increase the irreversible loss of the system. Meanwhile superheat ORC system induces that the engine waste heat cannot utilize fully. So superheat ORC system is not fit for the engine waste heat.
