气悬浮压缩机冷水机组的研究现状及测试

Research Status and Test of Air Suspension Centrifugal Compressor Chiller

该文介绍了国内气体动压轴承的研究现状以及问题,由于气悬浮离心压缩机的样机很少,该文选取了乐金空调(山东)有限公司研制的气悬浮变频离心式冷水机组(型号:MCWFLLH)作为样机进行测试,给出了部分实验数据供参考,从测试数据可以看出气悬浮离心冷水机组的能效比和IPLV接近磁悬浮离心压缩机,而气悬浮变频离心式冷水机组相较于磁悬浮变频离心式冷水机组成本更低、结构更简单、体积更小,所以气悬浮技术是未来发展趋势。

The research status and test of air suspension compressor chiller this paper introduces the research status and problems of domestic pneumatic pressure bearing.Because of the few prototype of air suspension centrifugal compressor,this paper selects the air suspension variable frequency centrifugal chiller(model:MCWFLLH)developed by lejin air conditioning(Shandong)Co.,Ltd.as the prototype for testing,Some experimental data are given for reference.It can be seen from the test data that the energy efficiency ratio of air suspension centrifugal chiller is close to that of the IPLV.Compared with the maglev variable frequency centrifugal chiller,the cost of the air suspension variable frequency centrifugal chiller is lower,the structure is simpler and the volume is smaller,so the air suspension technology is the future development trend.
