在(230~344)K温度范围内测量了制冷剂氟乙烷(HFC-161)的密度数据，并用VDNS型和修正的Rackett型密度方程对HFC-161的液体密度实验数据进行了关联，给出了密度方程的参数。相关结果表明，它们与实验数据有很好的一致性。液体密度与VDS型密度方程和修正的Rackett型密度方程的平均相对偏差分别为0.11%和0.09%。此外，还关联了Peng-Robinson(PR)状态方程，计算了HFC-161的液体密度。与PR方程的平均相对偏差和最大相对偏差分别为1.26%和5.15%，略大于VDNS型和修正的Rackett密度方程。然而，蒸气密度的计算结果与PR方程相吻合。
Density data of the refrigerant ethyl fluoride (HFC-161) have been measured in the range of temperatures from (230 to 344) K. Liquid density experimental data of HFC-161 are correlated by the VDNS-type and the modified Rackett-type density equations, and the parameters of the density equations are given. The correlated results show that they have a good agreement with the experimental data. The average relative deviation of liquid density from the VDNS-type density equation and from the modified Rackett-type density equation are 0.11 % and 0.09 %, respectively. In addition, the Peng–Robinson (PR) equation of state is also correlated to calculate the liquid density for HFC-161. The average relative deviation and maximum relative deviation from the PR equation are 1.26 % and 5.15 %, respectively, which are a little larger than those from the VDNS-type and the modified Rackett density equations. However, the vapor density results have been supplied with the PR equation.
