About This Item
Full Description
The fractionation of two refrigerant blends was studied using the gas equilibrium method. The amount of fractionation was measured by maintaining a constant composition of the refrigerant gas vapor over the lubricant, which was equal in composition to the liquid refrigerant gas blend introduced into the viscometer. Specifically, the concentration of the dissolved refrigerant gas in the lubricant ranges from 0.6% to 78% by weight in the specified temperature range of -25°C to 125°C (-13°F to 257°F) and within the highest test pressure of 500 psia (3.45 MPa). The polyolester chosen for this study was a 32 ISO VG complex branched acid pentaerythritol product. Smoothed graphical data presented were obtained from individual isothermal measurements. These individual isothermal measurement temperatures detail the composition of the equilibrium gas fractionation of R-32 and R-134a in the lubricant, mixed vapor pressure, concentration of the total mixed blend as percent by weight in the lubricant and viscosity in centipoise (cP) and centistokes (cSt). The raw data are presented in a smoothed graphical form based on a fixed vapor composition.
