摘要
离子液体[mmim]DMP/CH_3OH溶液是具有一定应用潜力的新型吸收式制冷工质对,基于实验和文献数据,提出了针对该工质对的溶液饱和蒸气压、比热容和过量焓的经验方程,并绘制了p-t-x,h-ω图。在此基础上,对新工质对的单效吸收式制冷循环进行了分析,并与传统工质对进行了对比。结果表明:在一定工况范围内,[mmim]DMP/CH_3OH新工质对在循环倍率、COP等持性参数优于NH_3/H_2O体系,堪与LiBr/H_2O体系相媲美。
[mmim]DMP/CHaOH solution used as a new working pair in absorption refrigeration has wide application potential. Empirical equations of saturated vapor pressure, heat capacity, excess enthalpy about this working pair were obtained based on experimental and literature data, p- t- x, h-w charts were drawn. Base on these, new working pair used in the single-effect absorption refrigeration cycle were studied, and compared with traditional working pairs. The results revealed that [mmim]DMP/CH3OH as working pair is better than NHa/H2O system and is on a par with LiBr/H2O system in circulation ratio, COP and other characteristic parameters in the certain operating conditions.
