摘要

在原有的溶解度实验台位基础上，研制了一套基于可视等体积饱和法的制冷剂/润滑油溶解实验系统，增加可视窗口的实验本体、调整恒温系统以及改进搅拌系统。采用新研制的实验系统，实验研究了温度范围为283.15~348.15 K制冷剂HFO1234yf与角鲨烷的溶解吸收特性，并采用PR状态方程和HVOS混合规则及活度系数NRTL模型对实验结果进行了关联，计算值和实验值的平均相对误差为1.22 %。此外，温度范围为283.15 ~323.15 K内发现了不互溶分层的现象。

Abstract

On the basis of the original solubility experimental system

a new experimental system using the visual isochoric method was developed to measure the solubility for a refrigerant and a lubricant. In new experimental system

visual experimental cell was added

thermostatic system was adjusted

and magnetic stirring system was modified. Solubilities of HFO1234yf in squalane was measured between 283.15 K and 348.15 K. The experimental data were correlated by PR equation of state with HVOS mixing rule in which the excess Gibbs free energy was represented by the NRTL equation. The absolute average deviation between experimental and calculated data was 1.22 %. Moreover

the immiscibility between HFO134yf and squalane was found from 283.15 K to 323.15 K.
