摘要
本文研究了HCFO-1233zd(E)的制备方法、安全性及环境可接受性、热稳定性及材料相容性和制冷系统中的热力学性质,以及HCFO-1233zd(E)在有机朗肯循环、中高温热泵和发泡剂中的应用。结果表明:HCFO-1233zd(E)的热稳定性良好,在150℃并有铜、铝等金属和水存在的环境下未出现分解情况;HCFO-1233zd(E)临界温度比HFC-245fa较高,可以在最大运行压力下比HFC-245fa达到更高的蒸发温度从而提升效率,120℃工况下有机朗肯循环所需的泵功率可降低10.3%~17.3%,净循环效率最多可提升10.6%,可以优化系统整体性能,并且HCFO-1233zd(E)与HFC-245fa的物性十分相似,可以沿用HFC-245fa系统的部件,降低成本。因此,HCFO-1233zd(E)具有较好的工作性能和发展前景,可以作为HFC-245fa的替代制冷剂。
In this paper,the preparation methods of HCFO-1233zd(E),safety,environmental acceptability,thermal stability,material compatibility and thermodynamic properties in refrigeration systems are studied.The application of HCFO-1233zd(E)in organic Rankine cycle,medium and high temperature heat pump and foaming agent is also studied.The results show that:HCFO-1233zd(E)has good thermal stability and does not decompose in the presence of copper,aluminum and other metals and water at 150℃.The critical temperature of HCFO-1233zd(E)is relatively higher than that of HFC-245fa,and it can reach a higher evaporating temperature than that of HFC-245fa at the maximum operating pressure to improve the efficiency.The pump power of organic Rankine cycle can be reduced by 10.3%-17.3%,and the net cycle efficiency can be increased by up to 10.6%at 120℃,which can optimize the overall performance of the system.HCFO-1233zd(E)is very similar to HFC-245fa in physical properties.It can use the components of HFC-245fa system to reduce costs.Therefore,HCFO-1233zd(E)has better working performance and development prospects,and can be used as an alternative refrigerant for HFC-245fa.
