摘　　要：HFO/离子液体是一种非常有潜力的替代性吸收式制冷工质对。本文筛选了一种低黏度离子液体[DEME][TFSI],并基于等体积饱和法实验系统测量了R1234yf和R1234ze(E)在其中的溶解度。溶解度实验数据对比结果显示:[DEME][TFSI]对R1234yf和R1234ze(E)具有很高的吸收能力,R1234ze(E)在[DEME][TFSI]的溶解度高于R1234yf。利用NRTL方程对R1234yf和R1234ze(E)在[DEME][TFSI]的溶解度实验数据进行了关联,计算结果与实验值的AAD分别为2.1%和0.5%。HFO/ionic liquids are potential alternative working pairs for absorption refrigeration.In this work,a low viscosity ionic liquid[DEME][TFSI]was screened,and the solubility of R1234yf and R1234ze(E)in[DEME][TFSI]was measured based on the isochoric saturation method.The experimental data comparison results show that[DEME][TFSI]has a high absorption capacity for both R1234yf and R1234ze(E),the solubility of R1234ze(E)in[DEME][TFSI]is higher than R1234yf.The experimental data of the solubility of R1234yf and R1234ze(E)in[DEME][TFSI]was then correlated by NRTL equation.The AAD between the calculated results form NRTL equation and the experimental values were 2.1% and 0.5% respectively.
