| 摘 要： | 为满足CFCs替代研究和工程实际应用的需要,根据Перелъщтейн饱和液体密度关系式,提出了一种适用于推算乙烷系氟里昂饱和液体密度的基团贡献法.利用该方法在已知临界温度和临界比容或临界密度的条件下,可以对所有乙烷系氟里昂的饱和液体密度进行推算,该方法推算的平均偏差不超过1%,最大偏差不超过15%,可满足CFCs替代物研究和应用的需要.

| Abstract: | To meet the demands of the study of CFCs alternatives and the engineering application,a group contribution method is proposed to calculate the saturated liquid's density of freon in ethane class based on the equation of saturated liquid density of Перелъщтейн.On condition that the critical temperature and critical density or critical specific volume are known,the density of saturated liquid can be calculated with high accuracy.The obtained mean deviation and the maximum one are less than 1% and 15% separately,which can meet the demands of alternatives' studies and application. |
