In this work, solubilities were measured for R-1233zd(E) in PVE 68 oil between (283.15 and 343.15) K using an isochoric saturation method. The nonrandom two liquid (NRTL) model was applied to represent the solubility behavior of the R-1233zd(E)/PVE 68 oil mixture. According to the experimental data, we studied the differences in enthalpies between pure R-1233zd(E) and the R-1233zd(E)/PVE 68 oil mixture as well as the oil effect on the evaporator performance with different superheating and oil circulating mass fractions (C_g). In the pressure–enthalpy–vapor quality diagram, isotherm curves of pure R-1233zd(E) and the R-1233zd(E)/oil mixture have a separation point called the critical vapor quality that is mainly connected to solubility and C_g. Moreover, the enthalpy change rate (R_h) and nonevaporation quality (NEQ) are also associated with the solubility and C_g, especially at low superheating. A lower solubility and C_g will result in higher R_h and lower NEQ, which are favorable to the refrigeration cycle.

R-1233zd(E) 在 PVE 68 油中的溶解度以及油的存在对蒸发器性能的影响

在这项工作中，使用等容饱和法测量了 PVE 68 油中 R-1233zd(E) 的溶解度（283.15 和 343.15）K 之间。应用非随机二液 (NRTL) 模型来表示 R-1233zd(E)/PVE 68 油混合物的溶解度行为。根据实验数据，我们研究了纯R-1233zd(E)和R-1233zd(E)/PVE 68油混合物的热函差异以及不同过热度和油循环量下油对蒸发器性能的影响分数（Cg _）。在压力-焓-蒸气质量图中，纯R-1233zd(E)和R-1233zd(E)/油混合物的等温曲线有一个称为临界蒸气质量的分离点，主要与溶解度和C g_有关。此外，焓变率 ( R _h ) 和非蒸发质量 ( NEQ ) 也与溶解度和C _g相关，特别是在低过热度下。较低的溶解度和C _g将导致较高的R _h和较低的NEQ，这有利于制冷循环。
