Dear friends,

In my original opinion some concerns on the pre-setting compessor IGV opening:

1.this will result in compressor vibration when start up compressor without any pre-setting IGV opening.

2.And this also need to think of motor startup current. keep motor proper startup current. not overload during compressor start up .

Yesterday I am told the compressor IGV pre-setting opening is not only think of above two points but also have another concern . But didnot give me detailed information.

Who can give me some good explainations on compressor IGV Pre-setting opening?

Thanks in advance for your help.
