摘要

By taking R601 and R245ca as the cycle working fluid

the influence of reheat pressure ratio on low-temperature reheating organic Rankine cycle(ORC) system was investigated

on the basis of the first and second law of thermodynamics.Combined with programming through MATLAB and BEFPROP

the system net work was taken as the objective function to determine the optimal reheat pressure ratio.The results showed that

with an increase in evaporation temperature

the reheat pressure ratio gradually reduced while the system net work increased;the heat efficiency rose but the exergy efficiency decreased.The increase range of system net work was higher than that of the heat efficiency and exergy efficiency.In practical application

the maximum net work of the reheating ORC system should be ascertained according to the working fluid and evaporation temperature.
