选择跨临界CO2-[bmim]PF6作为新型的吸收式制冷工质对,考察了CO2在离子液体[bmim]PF6中的溶解度和CO2-[bmim]PF6工质体系的热物性。计算了在给定工况下循环的制冷特性并对结果进行了分析与讨论。
Transition-critical CO2-[ bmim] PF6 was selected as working fluid for absorption refrigeration, the solubility of CO2 in ionic liquid [ bmim ] PF6 and thermodynamic properties of CO2- [ bmim ] PF6 were investigated. The efficiency of the refrigeration cycle at given condition was calculated and the result was analyzed.
