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。
A UNIFAC model capable of predicting [mmim] DMP / CH3OH solution vapor pressure parameters over the entire concentration range and a Wilson model predicting excess enthalpy parameters are associated. Based on the above model, the thermodynamic characteristics of [mmim] DMP / CH3OH single pass refrigeration cycle were simulated. The results show that the single-effect refrigeration cycle of [mmim] DMP / CH3OH is higher than that of LiBr / H2O and NH3 / H2O systems; Higher than the NH3 / H2O system.
