摘　　要：关联了能够在整个浓度范围预测[mmim]DMP/CH3OH溶液蒸汽压参数的UNIFAC模型和预测过量焓参数的Wilson模型。基于上述模型,对[mmim]DMP/CH3OH吸收式制冷单效循环热力特性进行了仿真分析。结果表明:[mmim]DMP/CH3OH单效制冷的循环倍率高于LiBr/H2O和NH3/H2O系统;[mmim]DMP/CH3OH单效制冷循环COP略低于LiBr/H2O系统,但在整体性能上要高于NH3/H2O系统。In order to predict the vapor pressure and the excess enthalpy of [mmim]DMP/CH3OH in the whole range of [mmim]DMP mole fraction, the UNIFAC model and the Wilson model are correlated. Based on the above models, thermodynamic performances of [mmim]DMP/methanol absorption refrigeration are investigated and analyzed. From the results, some conclusions are obtained as follows. The circulation ratio of the [mmim]DMP/methanol absorption refrigeration is higher than that of the LiBr/H2O and NH3/H2O absorption refrigeration. The COP of the [mmim]DMP/methanol absorption refrigeration is lower than that of the LiBr/H2O absorption refrigeration, but generally higher than that of NH3/H2O absorption refrigeration.
