Herein, the application of Carnahan-Starling-vdW-β equation of state (EoS) for 13 refrigerant fluids was investigated. The EoS could predict the saturated liquid densities of these refrigerants over the temperature range of 100-400 K and pressures from zero up to187 MPa with the average absolute deviations of 2.66%. The accuracy of Carnahan-Starling-vdW-β EoS in liquid density prediction was also compared with Peng-Robinson EoS and a perturbed hard-sphere-chain EoS. The surface tension and sound velocity of the saturated refrigerants were also calculated using the Carnahan-Starling-vdW-β EoS within 4.76%. and 5.66%, respectively. Finally, Carnahan-Starling-vdW-β was employed to predict Joule-Thomson inversion curve for some studied refrigerant fluids
