摘要
选择两种强亲水性离子液体1-乙基-3-甲基咪唑磷酸二乙酯盐[Emim]DEP和1,3-二甲基咪唑磷酸二甲酯盐[Mmim]DMP为吸收剂.对于H_2O-[Emim]DEP体系和H_2O-[Mmim]DMP体系作为新型工质对应用到吸收式制冷循环中的性能系数和循环倍率进行了计算,同传统吸收式循环工质对H_2O-LiBr体系进行比较,两个体系均具有较高的性能系数,H_2O-[Mmin]DMP体系更加具有成为高效吸收式工质对的潜力.最后分析了发生温度、蒸发温度和吸收温度等因素对循环性能的影响.
Two ionic liquids 1-ethyl-3-methylimidazolium diethylphosphate（[Emim]DEP）and 1-methyl-3-methylimidazolium dimethylphosphate（[Mmim]DMP）,which have super water-absorption capabity,were selected as absorbents in this study.Coefficient of performance（COP）and solution circulation ratio（f）of H_2O-[Emim]DEP system and H_2O-[Mmim]DMP system as new working pairs for absorption refrigeration cycles were calculated and compared with the traditional lithium bromide-water working pair.Two systems both had higher COP.At last,the influences of generation temperature,evaporating temperature,absorption temperature and other factors on the cycle performance were analyzed.
