In the present study, the characteristics of thermal efficiency and turbine power outputs are investigated for power generation system of waste heat energy from ship engine using HFO-1234yf as an environmentally acceptable green refrigerant. Also, these characteristics of HFO-1234yf are compared with that of conventional working fluids such as HFC-245fa, ammonia, and isopentane. The cycle simulations are carried out with both cases of warm water temperature difference and cold water temperature difference varies. In terms of cycle thermal efficiency, the values of HFO-1234yf were smaller than that of other working fluids. The turbine power outputs were comparable to that of HFC-245fa and isopentane in each case. From these results of cycle simulations, HFO-1234yf can be appropriate candidate for HFC-245fa as a working fluid of power generation system of waste heat energy from marine engine.
