Two-phase flow of the throttled refrigerant was investigated in a special divided small-diameter tube equipped with pressure and temperature sensors. Gas impurities affected the manner of onset of vaporization and consequently decreased the overall effectiveness of a vapor cooling circuit. Available literature data on three gases (O2, Xe, N2) was collected and analyzed to establish a simple temperature correlation for the Henry's law constant of gases dissolved in saturated fluorocarbons at a low gas partial pressure around 0.1 MPa. The Peng-Robinson cubic equation of state and the perturbed-chain modification of statistical associating fluid theory (PC-SAFT) were employed to predict the temperature dependency of gas solubility in fluorinert substances.
