摘要
介绍工业用新型氨/乙烯为制冷剂的螺杆复叠式低温机组。通过对一个深冷项目实例的分析,提供了设计中应注意的要点及解决的方法,并与R22/R23为制冷剂的螺杆复叠式低温机组进行了比较。
A new Screw compressor type cascade low temperature unit is introduced, using R717/R1150 as the refrigerants. Through a low temperature project application example, some analysis for the design is provided. The comparison with R22/R23 cascade unit is described.
