为了更完善地认识新型制冷剂HFO-1234ze(E)的热物性,在公开发表的HFO-1234ze(E)饱和蒸气压实验数据的基础上,通过仔细分析各个实验数据的精确程度,筛选出一套由118组数据点组成的综合数据,经过拟合得到一系列蒸气压方程,对比各个方程对拟合数据的绝对偏差和相对偏差,得到一个适用范围较宽(232.990-380.002 K)且精度良好的四项Wanger型HFO-1234ze(E)蒸气压专用方程.该方程对拟合数据的平均相对偏差为-0.02％.同时,通过新方程计算得到HFO-1234ze(E)的正常沸点以及偏心因子,可以供物性计算和工程运用,具有较高的实际应用价值.%In order to better understand the thermalphysieal properties of the new refrigerant HFO-1234ze (E),the saturated vapor pressure experimental data based on the published HFO-1234ze (E) were studied.After carefully analysing the accuracy of every experimental data,a set of comprehensive data including 118 groups of data points were screened out.After fitting and comparing,four terms Wanger type HFO-1234ze (E)vapour pressure specific formula with a wider range and good accuracy is conducted.The specific formula has an average relative deviation value-0.02％ for the fitting value.At the same time,the normal boiling point and eccentricity factor of HFO-1234ze (E)are calculated from this formula,which are used in calculating the physical properties and applying engineering,with high actual application values.
