以[mmim]DMP-甲醇为工质对的吸收式制冷循环研究

采用离子液体mmim]DMP-甲醇作为吸收式制冷系统工质对，运用文献提出的mmim]DMP-甲醇二元溶液经验方程进行制冷循环计算研究，并将此系统的工作压力、COP等与相同工况下的溴化锂-水、氨-水制冷循环进行比较。研究结果表明：mmim]DMP-甲醇工质对制冷系统工作压力要求适中，COP稍高于NH3／H2O系统，低于H2O／LiBr系统；mmim]DMP-甲醇溶液对金属无腐蚀，其适用范围要大于H2O／LiBr系统，具有一定的应用价值。

Research on absorption refrigeration cycle with [mmim]DMP-methanol

Ionic liquid of mmim]DMP-methanol is adopted as working pairs for absorption refrigeration system. The computation of refrigeration cycle utilizing the working pairs is carried on with the empirical equations of mmim]DMP-methanol provided in the relevant literatures,and the operation pressure and COP are compared with the BrLi-H2O or NH3-H2O absorption refrigeration systems. The results show that the working pressure of new refrigerant system is medium,COP is slightly higher than NH3/H2O system and lower than H2O/LiBr system. But the mmim]DMP- methanol solution is not corrosive to metals and the range of application is wider than H2O/LiBr, and has certain application value.
