ABSTRACT
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.
