制冷循环中经济器设置的数量对压缩机功率的影响分析

Analysis of Effect on Compressor Power by Economizer Numbers in Refrigeration Cycle

介绍制冷系统设置经济器的必要性以及中间压力的确定。以丙烯为制冷介质,通过工程实例对比设置一级经济器及两级经济器的制冷系统中离心压缩机的功率。

This paper describes the necessity of economizer set in refrigeration system and determination of intermediate pressure. Using propylene as refrigeration medium,this paper through engineering examples contrasts the centrifugal compressor powers of refrigeration system equipped with one-level economizer and two-level economizer.
