Two adjacent frequency values of rate are boundary；
Power setting unit, for the working frequency of the compressor to be adjusted to second working frequency.
8. device according to claim 7, which is characterized in that air-conditioning manufacture before, the multiple working frequency by with
Lower device setting：
Frequency setting device, work frequency when minimum frequency of operation and maximum duty for making compressor be limited in the system
It is run between rate, according to the second condition, determines multiple working frequencies of the setting.
9. device according to claim 7, which is characterized in that further include：Power detecting unit, for detecting the compressor
Whether meet the second condition when working in first working frequency, if so, first working frequency is determined
For second working frequency；If it is not, then triggering the second frequency acquiring unit, make the compressor including described first
It is run on the frequency band of working frequency, the second working frequency is determined according to the second condition of the setting.
10. device according to claim 7, which is characterized in that the first frequency acquiring unit includes：
The first adjustment subelement, for making compressor sequentially be transported in multiple working frequencies of the setting from high to low according to frequency
Row；With,
Power detection subelement judges whether the output power of the air-conditioning at that time meets described the in each run
One condition；The first condition is：The output power of the air-conditioning at that time meets the requirement of outside electric power network；
If so, the working frequency of the compressor at that time is determined as first working frequency, and triggers described first and adjust
Whole subelement makes the compressor stop continuing to run in subsequent work frequency.
11. device according to claim 7, which is characterized in that the second frequency acquiring unit includes：
Second adjustment subelement, for make compressor according to frequency from high to low, with default step-length it is described include first work
It is run on the frequency band of working frequency；With,
Vibrating sensor, in the operation, whether the vibration amplitude for detecting compressor in real time to meet the second condition；
If so, corresponding working frequency is determined as second working frequency, and the second adjustment subelement is triggered, made
The compressor stops continuing to run in the working frequency less than second working frequency.
12. according to the device described in claim 7,8,9 or 11 any one, which is characterized in that the second condition is：It is described
The vibration amplitude of compressor meets the requirement of normal work.
13. a kind of air-conditioning, which is characterized in that further include device as claimed in claim 12.
