In the present embodiment, further setting speed is adjusted so that compressor pressure ratio preferably follow it is pre-
If pressure ratio, avoid generating surge phenomenon.
In the present embodiment, when in setting speed section including a predetermined level revolving speed, the setting speed section
Maximum speed it is identical with minimum speed；When setting speed section includes multiple predetermined level revolving speeds, in the setting speed
Maximum speed and minimum speed difference, for example, when including that the 1st grade of revolving speed, the 2nd grade of revolving speed and 3rd level turn in setting speed section
When fast, maximum speed is 3rd level revolving speed, and minimum speed is the 1st grade of revolving speed.About change level-one setting speed, including improve
Level-one setting speed and reduction level-one setting speed: it if a certain moment setting speed is the 2nd grade of revolving speed, improves level-one setting and turns
After speed, setting speed is 3rd level revolving speed；If a certain moment setting speed is the 2nd grade of revolving speed, after reducing level-one setting speed,
Setting speed is the 1st grade of revolving speed.
