“…The development of EoS is also shorter than experimental approaches. Some EoS approaches have been applied to study the VLE of binary refrigerant mixtures, including modified Peng-Robinson (PR) EoS [11,[16][17][18][19][20], PR + non-random twoliquids model [12,14,[21][22][23][24], modified statistical associating fluid theory (SAFT) EoS [25,26], Patel-Teja EoS [13], and Carnahan-Starling-DeSantis EoS [20,27]. Although these calculation works gave good performances, there are few EoS calculation works that consider hydrogen-bonding associations.…”

The binary refrigerant mixtures containing 2,3,3,3-Tetrafluoroprop-1-ene are considered as excellent substitutes for traditional refrigerants. Weak hydrogen bonds exist in hydrofluorocarbons and hydrofluoroolefins. However, for several recently published binary refrigerant mixtures, there is no Vapor–Liquid Equilibrium calculation study considering hydrogen-bonding associations. This work presents a calculation work of the saturated properties of nine pure refrigerants using the Cubic-Plus-Association Equation of State, considering the hydrogen-bonding association in refrigerant fluids. The average relative deviations of the saturated vapor pressure, liquid, and vapor density are less than 1.0%, 1.5%, and 3.5%, respectively. The Vapor–Liquid Equilibrium of ten binary refrigerant mixtures containing 2,3,3,3-Tetrafluoroprop-1-ene is also calculated using the Cubic-Plus-Association Equation of State with the van der Waals mixing rule. The average relative deviations of the liquid-phase and vapor-phase mole fractions are less than 1.0% and 2.0%, respectively. Moreover, the Vapor–Liquid Equilibrium data and the model’s adaptability are analyzed and discussed.
