摘　　要：结合多元精馏的操作型计算 ,采用了网格穷举法和机理法相结合的成分优化方法 ,对多元混合工质精馏循环进行了数值优化计算 ,得到了压比为 8,温度为 -60 ,-80 ,-10 0 ,-12 0°C等 4个温度位的混合工质最佳成分 ,并进行了实验验证。Combining with the operational calculation of multi component rectification,a new composition optimizing method is initially applied to the numerical optimization of the multi component rectification cycles using mixed refrigerants.We obtained the optimum compositions of the mixture refrigerant for the rectification cycles at the pressure ratio of 8 when the temperature of low temperature heat reservoir is -60 °C,-80 °C,-100 °C and -120 °C respectively.The experimental results are consistent with the results of numerical optimization.
