Detailed knowledge about the properties (such as phase behavior, viscosity, and density) of hydrofluoroolefin (HFO)/lubricant mixtures is necessary for the design and optimization of the refrigeration facility. In this work, measurements on the solubility (p-T-x) of trans-1,3,3-tetrafluoropropene [R1234ze(E)], 3,3,3-trifluoropropene (R1243zf), and 2,3,3,3-tetrafluoropropylene (R1234yf) in polyolester oil (POE46) were performed using the isochoric saturation method at temperatures ranging from 283.15 to 343.15 K. The obtained results were correlated with the NRTL activity coefficient model and the Wilson activity coefficient model, respectively, where the NRTL model shows higher accuracy for the studied mixtures. Moreover, the solubility of R1234ze(E), R1243zf, and R1234yf in different viscosity grade POE oils including POE32, POE46, POE75, and POE85 is compared and discussed.

283.15 至 343.15 K 温度下 R1234ze(E)、R1243zf 和 R1234yf 在 POE46 中的溶解度测量

对于制冷设施的设计和优化，需要详细了解氢氟烯烃 (HFO)/润滑剂混合物的特性（例如相行为、粘度和密度）。在这项工作中，测量了反式 1,3,3-四氟丙烯 [R1234ze(E)]、3,3,3-三氟丙烯 (R1243zf) 和 2,3,3 的溶解度 ( p - T - x )，使用等容饱和法在 283.15 至 343.15 K 的温度下对多元醇酯油 (POE46) 中的 3-四氟丙烯 (R1234yf) 进行分析。所得结果分别与 NRTL 活度系数模型和 Wilson 活度系数模型相关，其中NRTL 模型对所研究的混合物显示出更高的准确性。此外，还比较和讨论了R1234ze(E)、R1243zf和R1234yf在不同粘度等级POE油（包括POE32、POE46、POE75和POE85）中的溶解度。
