| 摘 要： | 针对使用R134a／R23混合制冷剂的自然复叠制冷系统．编制了基于NISTREFPROP的仿真程序。利用仿真和实验对系统各种优化措施的效果进行了分析和验证。两者都表明：分凝措施有利于降低系统蒸发温度、提高COP;而回热可以略微降低系统蒸发温度，但使系统COP降低、压缩机排气温度升高。

| Abstract: | A simulation program based on NIST REFPROP is designed in accordance with an auto-refrigeration cascade system using R134a/R23 mixing refrigerant. Results of all optimal measure of this system are analyzed and tested by simulation and experiment, which show that segregation will increase COP and decrease evaporation temperature; and regeneration causes a little decrease of evaporation temperature, but reduces COP and causes the increase of compressor discharge temperature. |
