The organic Rankine cycle was modeled using Aspen Plus, with heat transfer oil as the heat source and water at the liquid level as the cooling source; R245fa was used as the working fluid. The simulation assumptions were as follows: the temperature of the heat transfer oil was 120, while that of the cooling water was 20. The flow rates of both can be adjusted according to the actual heat exchange requirements； The mass flow rate is 0.06 kilomoles per second, the evaporation pressure is 0.5 MPa, and the condensation pressure is 0.15 MPa; the isentropic efficiency of the expander is 0.78, the isentropic efficiency of the pump is 0.9, and the ambient temperature in the laboratory is 20°C. How to do it? I need advice, urgently!
