摘要
提出将[bmim]Cl/CH3OH应用为吸收式制冷工质对,并从多角度对其应用潜能进行分析。采用静态法饱和蒸气压测定装置、DSC、乌氏黏度计和比重瓶等测定了293.15~353.15K温度范围内[bmim]Cl/CH3OH溶液的汽液平衡、比热容、黏度和密度,拟合得到溶液汽液平衡的NRTL模型参数以及比热容、黏度、密度随浓度和温度的经验关联式。结果表明:[bmim]Cl/CH3OH溶液的性质满足理想吸收式制冷工质对的要求,在吸收式制冷中有较大的应用潜能。
The [bmim] Cl/CH3OH solution as working fluid for absorption refrigeration is proposed and its application potentials are analyzed in different aspects. The vapor-liquid equilibrium, heat capacity, viscosity and density of [bmim] Cl/CH3OH solution were measured respectively with saturation vapor pressure determination system, DSC, Ubbelohde viscometers and pycnometers in the temperature range from 293.15 K to 353.15 K. The NRTL model parameters of vapor-liquid equilibrium and the empirical correlations for heat capacity, viscosity and density as functions of temperature and concentration were obtained. The results revealed that the properties of [bmim] Cl/CH3OH solution can meet the requirements of ideal working fluid for absorption refrigeration and has great application potentials in absorption refrigeration.
