摘要:

针对90℃~200℃的低温余热有机朗肯循环系统,选取SES36、R1233zd-E两种新工质与R245fa、R123两种传统工质在不同的环境温度下基于热力学效率、净功量、系统不可逆损失以及蒸发器出口工质的可用势热力学性能进行了对比分析,分析结果表明工质在不同的热力学性能参数下都有其最佳蒸发温度。而在各自临界温度以下热力性能优劣程度依次为R123,R1233zd-E,R245fa,SES36。综合考虑安全性、环境友好性、设备成本方面,R1233zd-E是良好的R123和R245fa的替代品,SES36次之。

The present study focuses on Organic Rankine Cycle power generation system whose heat source is the industrial waste heat in the temperature range of 90˚C~200˚C, including SES36, R1233zd-E two kinds of new refrigerants and R245fa, R123 two kinds of conventional refrigerants at different am-bient temperatures based on thermodynamic efficiency, system net work, irreversible loss and the outlet of the evaporator refrigerant thermodynamic properties of available potential to make com-parison. The results of analysis show that the refrigerant has the best evaporation temperature un-der different thermodynamic performance parameters. Under the critical temperature, the order is R123, R1233zd-E, R245fa and SES36. Considering the safety, environmental friendliness and equipment cost, R1233zd-E is a good substitute for R123 and R245fa, and SES36 ranks the second.
