摘要
介绍NH_3/CO_2复叠式制冷系统以及螺杆式压缩机在CO_2亚临界循环中的研究现状,通过搭建试验系统并进行系列螺杆式压缩机试验,结合螺杆式压缩机优点及试验结果分析,认为螺杆式压缩机适合应用于CO_2亚临界循环。
The research status of NH_3/CO_2 cascade refrigeration system and the application of screw compressor to CO_2 subcritical system are mainly introduced.The experiment system is established to conduct the series tests on compressor.Combined with the advantages of screw compressor and the experiment results analysis,it＇s considered that screw compressor is reliable in CO_2 subcritical system.
