Abstract
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.关键词
