| description | To measure the vapor-liquid equilibrium (VLE) of refrigerants/lubricants, a refrigerants/lubricants VLE experimental system with high precision was developed based on the cycle method. The circulation system was equipped with a detachable sample tank. It combined the cycle method and weighing method and eliminated the systematic error of isochoric saturation method due to the assumption. Furthermore, it could measure the VLE of refrigerants/lubricants at a temperature range of 263.15 K to 373.15K. The saturated vapor pressure of R290 was measured from 293.35 K to 323.33 K. The relative deviation of the pressure was less than -0.18% when compared to NIST REFPROP9.1. Additionally, the phase equilibrium values of R290 and squalane were measured at 303.35 K. The experimental data and literature data were correlated with the Peng–Robinson (PR) equation of state and one-fluid van der Waals mixing rules in Aspen Plus, and the results indicated maximum relative deviation of pressure of-0.37% and0.76%, respectively. |
