Based on the bubble point and dew point data of mixture refrigerant HFC152a/HCFC22, the interaction coefficient of Peng Robinson equation, which is suitable to calculate the mixture thermodynamic properties, was determined, and the pressure enthalpy diagram and the saturated properties were made. Saturated properties tables covering the temperature range of -80～100 degree centigrade and the pressure range of 10 kPa～3 MPa were listed with the temperature and pressure basis, respectively. The thermodynamic properties include temperature, pressure, specific volume, enthalpy, entropy, exergy, quality etc.. The equations to calculate the thermodynamic properties were also presented.
