摘要
Experimental solubilities of difluoromethane (R32) in polyol ester (POE), polyvinylether (PVE), and polyalkylene glycol (PAG) base oils were measured in the temperatures range from 273 K to 351 K based on the isochoric method. The experimental setup was checked by measuring the solubility of carbon dioxide in n-decane at pressures from 0.1 to 4.6 MPa. The expanded uncertainty (k = 2) of the measured solubility data was estimated to be less than 2.8%. The experimental solubility data were correlated using the Peng–Robinson (PR) equation of state (EOS) and Wilson activity coefficient model. The absolute average deviations of the experimental data and calculated values for R32 in POE, PVE, and PAG base oils were 1.74%, 0.73%, and 0.97%, respectively. The solubility of R32 in three base oil were calculated and compared at same temperatures and pressures, and the results showed that the solubility order of R32 in the three base oils was: PAG > PVE > POE.
