不同冷冻润滑油对HFO1234yf溶解吸收特性的研究
Investigation of solubility behavior between HFO1234yf and lubricants
摘要
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.关键词
