摘要
对两级复叠制冷系统低温级设计中诸如制冷剂和润滑油的选择、润滑油分离、低温换热器和载冷剂的性能等问题进行讨论,同时结合试验结果,指出R23替代R13时一些问题的处理方法。
Discusses some problems of the low temperature stage refrigeration system for two-stage cascade refrigeration system, such as selection of refrigerant and lubricant, oil handling,the performance of the low temperature heat exchanger and secondary coolant applied to the cascade refrigeration system. Also focuses on some problems for replacing R13 with R23.
