Method for performance parameter recording and apparatus, frequency inverter, air conditioner, and storage medium

A performance parameter recording apparatus, applied in a frequency inverter and comprising:

• a first sampling data determination module configured to obtain first sampling data by sampling a performance parameter of the frequency inverter based on a first predetermined sampling period;
• a second sampling data determination module configured to obtain second sampling data by sampling a performance parameter of the frequency inverter based on a second predetermined sampling period, the first predetermined sampling period being smaller than the second predetermined sampling period;
• and
• a fault data storage module configured to store, in response to a fault in the frequency inverter, fault data prior to and subsequent to the fault in the frequency inverter, the fault data comprising the first sampling data and the second sampling data.

A storage medium, having a computer program stored thereon,

• wherein the computer program, when executed by a processor, causes the processor to:
• obtain first sampling data by sampling a performance parameter of the frequency inverter based on a first predetermined sampling period;
• obtain second sampling data by sampling a performance parameter of the frequency inverter based on a second predetermined sampling period, the first predetermined sampling period being smaller than the second predetermined sampling period;
• and
• store, in response to a fault in the frequency inverter, fault data prior to and subsequent to the fault in the frequency inverter, the fault data comprising the first sampling data and the second sampling data.
