摘要

以文献提供的大量精确pVT实验数据为基础

拟合了制冷工质七氟丙烷HFC-227ea的modified benedict-webb-rubin(MBWR)状态方程

给出了32个参数值.该方程适用压力从0.03至53 MPa

密度从2.9至1 800 kg/m3

温度从204至473 K.将该方程计算的HFC-227ea的pVT数据与实验数据比较后表明:两者的气相压力平均绝对值偏差为0.296%

饱和蒸气压平均绝对值偏差为0.213%

液相密度平均绝对值偏差为0.148%.

Abstract

pVT experimental data of HFC-227ea published in literature were collected

and then modified benedict-webb-rubin(MBWR)equation of state of HFC-227ea was fitted. Moreover

the values of 32 parameters in MBWR equation were obtained. This equation is suitable for conditions of the pressure from 0.03 MPa to 53 MPa

density from 2.9 kg/m

to 1 800 kg/m

and temperature from 204 K to 473 K. The average absolute deviations of this equation for gaseous phase pressure

vapor pressure and liquid density are 0.296%

0.213% and 0.148%

respectively.
