Key words: organic Ｒankine circulation system( OＲC) ; reheat; thermodynamic performance; low-temperature exhaust heat
Abstract: The thermodynamic performance of reheating OＲC system with different kinds of working fluid was studied to utilize the lowtemperature exhaust heat．The net output work，circulation heat and thermal efficiency at different temperature were obtained ．The performance of the reheating OＲC system was compared with that of the basic OＲC system，and the optimal pressure ratio was also analyzed．
