摘　　要：有机朗肯循环作为回收发动机废热的有效手段,在商用车领域受到关注。R245fa是常见的有机朗肯循环工质,随着碳排放标准日趋严格,GWP高于150的制冷剂未来将面临淘汰。本文中提出一种新型低GWP制冷剂R1233zde替代R245应用于有机朗肯循环,物性与R245fa相近,GWP为7。并针对有机朗肯循环,建立了系统仿真模型,比较相同工况下两种工质的性能参数:蒸发温度,泵耗功和循环热效率。分析表明R1233zde泵耗功相比减少约15.05%~17.02%,R1233zde最大热效率比R245fa高7.03%。Organic Rankine cycle gains attention from commercial vehicle field as a feasible method to recover engine waste heat.R245fa is a regular working fluid utilized in ORCs.With increasingly stringent carbon emission standards,refrigerants with GWP higher than 150 will be abandoned in the future.In this paper,a new competitor R1233zde with low GWP is proposed as an alternative to R245fa for organic Rankine cycle.Thermodynamic properties of R1233zde are extremely close to R245fa but with low GWP 7.A steady state simulation of ORC system is established to compare parameters performance including evaporating temperature,pump power consumption and cycle efficiency between the two working fluids under the same operating condition.Results show that pump power consumption of R 1233zde is reduced by 15.05%-17.0 2%and the optimal cycle efficiency of R1233zde is 7.0 3%higher than R245fa.
