When using Aspen to simulate the organic Rankine cycle, how to determine the optimal evaporation temperature and optimal condensation temperature

When using Aspen to simulate the organic Rankine cycle, how do you determine the optimal evaporation temperature and the optimal condensation temperature? Find the formula.
That’s a good question; I look forward to answers from experts.
This question should be sent to the process section.
I have simulated it before, and to share my simple personal opinion, first of all, the physical property method must be chosen correctly; that is the most important thing. 1: The optimal evaporation temperature is the boiling point of the organic medium plus 5°C, to turn it into superheated steam. 2: Is this Rankine cycle a simple 4-component system, or one that includes temperature recovery? 3: It depends on what your cooling medium is – low-temperature cooling water or regular cooling water – and what the temperature difference for heat exchange is.
