Owing to the worse greenhouse gas effect, the global warming problem is becoming more and more serious. Exploring suitable refrigerants to replace high-GWP HFCs is currently one of the key issues of concern in the refrigeration field. Among alternatives, trans-1-chloro-3,3,3-trifluoropropene (R-1233zd(E)) is attracting a lot of fashionable attention in the refrigeration and air conditioning industry. To increase the database of solubility and enthalpy for R-1233zd(E) with polyol ester (POE) and polyalkylene glycol (PAG) oils, as well as reveal the oil retention influence on the evaporator in a vapor compression refrigeration system using R-1233zd(E), the miscibility and solubility behaviors were investigated for R-1233zd(E) with POE75, POE85, and PAG68 oils using an isochoric method between 298.15 and 343.15 K. The non-random two liquid (NRTL) equation was applied to correlate and predict the solubility. Pressure–enthalpy–vapor quality (p–h–X) diagrams were presented for R-1233zd(E) at oil circulation mass fractions (C g) of 2 and 4%. Meanwhile, the differences were analyzed for the enthalpy change and nonevaporated quantity.

“…Deep insights into the solubility level of R-1233zd(E) in PVE 68 oil and solubilities in PVE 68 oil for R-32, R-290, and R-1233zd(E) were compared. We found that the solubilities of R-1233zd(E) in PVE 68 oil are higher than those of R-32 and R-290 in PVE 68 oil under the same conditions.…”

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.
