1-Ethyl-3-methylimidazolium chlorine ([Emim]Cl) and 1-ethyl-3-methylimidazolium bromide ([Emim]Br) as an additive to working fluid [lithium bromide aqueous solution (H2O/LiBr) and lithium chloride aqueous solution (H2O/LiCl)] of absorption cycles were proposed. The vapor pressure of H2O + LiCl + [Emim]Cl (mass ratio LiCl/[Emim]Cl = 2) in the temperature from 314.79 to 435.48 K, H2O + LiCl + [Emim]Br (mass ratio LiCl/[Emim]Br = 2) in the temperature from 317.62 to 431.27 K, and H2O + LiBr + [Emim]Cl (mass ratio LiBr/[Emim]Cl = 2) in the temperature from 303.10 to 409.91 K was measured by the boiling point method. The mass fractions of the absorbent were from 0.30 to 0.60. The experimental data were regressed using the Antoine-type equation, and the average absolute relative deviation (AARD %) between the experimental data and calculated values of three systems was 0.44, 0.51, and 0.54%. Compared with that of the previously reported ionic liquids, ([Emim]Ac) as an absorbent for LiBr + H2O, vapor pressure of these four systems follows the order LiCl + [Emim]Cl + H2O < LiCl + [Emim]Br + H2O < LiBr + [Emim]Cl + H2O < LiBr + [Emim]Ac + H2O. The proposed ternary systems have better water affinity and can be promising alternative working fluids in the absorption cooling system.

三元体系LiCl + [Emim] Cl + H2O，LiBr + [Emim] Cl + H2O和LiCl + [Emim] Br + H2O的蒸气压测量
1-乙基-3-甲基咪唑鎓氯（[Emim] Cl）和1-乙基-3-甲基咪唑鎓溴化物（[Emim] Br）作为工作液[溴化锂水溶液（H 2 O / LiBr）和氯化锂的添加剂提出了吸收循环的水溶液（H 2 O / LiCl）。H 2 O + LiCl + [Emim] Cl（质量比LiCl / [Emim] Cl = 2）在314.79至435.48 K的温度下的蒸汽压，H 2 O + LiCl + [Emim] Br（质量比LiCl / [Emim] Br = 2），温度为317.62至431.27 K，H 2通过沸点法测量了在303.10至409.91K的温度下的O + LiBr + [Emim] Cl（质量比LiBr / [Emim] Cl ＝ 2）。吸收剂的质量分数为0.30至0.60。使用Antoine型方程式对实验数据进行回归，实验数据与三个系统的计算值之间的平均绝对相对偏差（AARD％）为0.44、0.51和0.54％。与先前报道的离子液体（[Emim] Ac）作为LiBr + H 2 O的吸收剂相比，这四个系统的蒸气压遵循LiCl + [Emim] Cl + H 2 O <LiCl + [Emim ] Br + H 2 O <LiBr + [Emim] Cl + H 2 O <LiBr + [Emim] Ac + H 2O.拟议的三元系统具有更好的水亲和力，并且有望成为吸收式冷却系统中的替代工作流体。
