采用混合工质R1234ze(E)/R245fa的ORC系统性能具有明显的提升。

Abstract

The temperature slip characteristic of zeotropic-mixtures

which can effectively improve the performance of the ORC system

has an essential investigation value. First the ORC system test bench was introduced

and then a zeotropic-mixture system model for a thermodynamic analysis was established. Next

the effect of zeotropic-mixture mass flow rate on the ORC system operation performance and the heat transfer characteristics were experimentally studied

and the results compared with those of the ORC with pure working medium system. The results indicate that the performance of the ORC utilizing zeotropic-mixture R1234ze (E)/R245fa has an obvious improvement.
