摘　　要：仿真设计了一种使用R134a/R23混合制冷剂的自然复叠制冷系统,对该系统的特性进行了分析。在此基础上,采取回热、分凝等措施对系统进行优化,对优化后系统的特性进行了比较和分析,发现分凝措施有利于系统性能改进,而回热不能促进系统性能明显改进,但与分凝合用时可以降低分凝器设计和制作难度。An auto-refrigeration cascade system which using R134a/R23 mixing refrigerant is designed, and the property of this system is studied. Then the optimized measures such as regeneration and segregation are used to the system. By comparing and analyzing, it is found that segregation can upgrade the system capability, and regeneration cannot upgrade the system capability remarkably, but it can release the design and manufacture pressure of partial condenser when it is used together with segregation.
