目前,制冷行业内关于双级压缩的理论和研究都是相对于活塞式压缩机和螺杆式压缩机而言,在涡旋式压缩机日益盛行的今天,迫切需要关于涡旋式双级压缩的试验和应用。本文从实际应用出发,介绍涡旋式单机准双级压缩系统的优点、计算及其在机组中的实际应用,最后从试验的角度验证涡旋式单机准双级压缩机的优点。
At present, the theory and research on two-stage compression in the refrigeration industry are both relative to piston compressors and screw compressors. With the increasing prevalence of scroll compressors, there is an urgent need for a two-stage compression Test and application. Based on the practical application, this paper introduces the advantages and calculation of scroll single-quasi-two-stage compression system and its practical application in the unit. Finally, the advantages of scroll single quasi-two-stage compressor are verified from the experimental point of view.
