在-13°F（-25°C）和257°F（125°C）之间以及高达700 psia（4824 kPa）的范围内，测量了使用制冷剂R-410A的四种粘度等级为32和68 ISO VG的聚烯烃润滑剂的制冷剂蒸汽/液体润滑剂平衡粘度降低。对每种粘度的高混溶性和低混溶性级聚烯烃进行了分析。通过在粘度计顶部空间中保持恒定的气体蒸汽成分，获得了含有润滑剂的溶液中溶解气体混合物的粘度、密度和成分。这种制冷剂的温度滑动很小，但仍被视为共沸混合物。所提供的分馏数据来自单独的等温测量。各温度的等温线详细说明了润滑剂中R-32和R-125平衡气体分馏的组成、混合蒸汽压、润滑剂中总混合混合物的浓度（重量百分比）以及以厘泊（cP）和厘斯托克斯（cSt）为单位的粘度。 单位:双引文:ASHRAE交易，第106卷，第。1

Measurements of the refrigerant vapor/liquid lubricant equilibrium viscosity reduction of four polyolester lubricants, viscosity grades 32 and 68 ISO VG, with the refrigerant R-410A were taken between -13°F (-25°C) and 257°F (125°C) and up to 700 psia (4824 kPa). A high and low miscibility grade polyolester was analyzed for each viscosity. The viscosity, density, and composition of the solubilized gas mixture in solution with the lubricant was obtained with constant gas vapor composition in the viscometer head space. This refrigerant has a very small temperature glide but is considered a zeotropic blend nonetheless. The fractionation data presented were obtained from individual isothermal measurements. The isotherm for each temperature detailed the composition of the equilibrium gas fractionation of R-32 and R-125 in the lubricant, mixed vapor pressure, concentration of the total mixed blend (percent by weight) in the lubricant, and viscosity in centipoise (cP) and centistokes (cSt).Units: Dual
