Abstract

Trans-1,3,3,3-tetrafluoropropene (R1234ze(E)) and trans-1,1,1,4,4,4-hexafluorobut-2-ene (R1336mzz(E)) are environmentally friendly working fluids with low global warming potential (GWP) that can be used in compression refrigeration and heat pump systems. In this study, a solubility measurement system was established to assess the solubility of R1234ze(E) and R1336mzz(E) in polyalkylene glycol ether (PAG) and polyol ester (POE) at temperatures (283.15–323.15 K). The Henry's constants for four binary systems R1234ze(E)/PAG, R1336mzz(E)/PAG, R1234ze(E)/POE, and R1336mzz(E)/POE were analyzed and compared. Additionally, The non-random two liquid (NRTL) activity coefficient model was applied to correlate the solubility data in this study. The results indicate that R1234ze(E) exhibits higher solubility in PAG lubricant, while R1336mzz(E) is more easily dissolved in POE lubricant. Moreover, the solubility of R1336mzz(E) in both PAG and POE lubricants shows greater sensitivity to pressure and temperature changes compared to R1234ze(E). The results reported in this study can serve as a valuable guide for the choice of suitable lubricants for R1234ze(E) and R1336mzz(E) in different applications.

反式-1,3,3,3-四氟丙烯（R1234ze(E)）和反式-1,1,1,4,4,4-六氟-2-丁烯（R1336mzz(E)）在两种润滑油中的溶解度比较：一项实验研究

反式-1,3,3,3-四氟丙烯（R1234ze(E)）和反式-1,1,1,4,4,4-六氟丁烯-2-烯（R1336mzz(E)）是全球升温潜能值（GWP）较低的环保型工作液，可用于压缩制冷和热泵系统。本研究建立了一个溶解度测量系统，以评估 R1234ze(E) 和 R1336mzz(E) 在温度（283.15-323.15 K）下在聚烷基乙二醇醚（PAG）和多元醇酯（POE）中的溶解度。分析并比较了 R1234ze(E)/PAG、R1336mzz(E)/PAG、R1234ze(E)/POE 和 R1336mzz(E)/POE 四种二元体系的亨利常数。此外，本研究还采用了非随机双液（NRTL）活性系数模型来关联溶解度数据。结果表明，R1234ze(E) 在 PAG 润滑油中的溶解度更高，而 R1336mzz(E) 在 POE 润滑油中更容易溶解。此外，与 R1234ze(E) 相比，R1336mzz(E) 在 PAG 和 POE 润滑油中的溶解度对压力和温度变化的敏感性更高。本研究报告中的结果可为 R1234ze(E) 和 R1336mzz(E) 在不同应用中选择合适的润滑油提供宝贵的指导。

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
