The invention provides a variable frequency centrifuge set, a control method thereof, a storage medium and an air conditioner. The variable frequency centrifuge set comprises a compressor, a main control cabinet, a condenser, an evaporator and frequency converters; the frequency converters comprise at least two modular frequency converters; and the at least two modular frequency converters communicate with a controller of the variable frequency centrifuge set through an industrial Ethernet. According to the scheme provided by the invention, the communication distance between the frequency converters and the main control can be improved, the distributed modularized frequency converter design of the centrifuge set is realized, and compressors with different power levels can be supplied withpower.
Description
technical field [0001] The invention relates to the field of control, in particular to a frequency conversion centrifugal unit, a control method thereof, a storage medium and an air conditioner. Background technique [0002] The frequency conversion centrifugal unit is usually composed of compressor, condenser, evaporator, main control cabinet, frequency converter and other components. Due to the structure of the centrifuge unit, there are strict requirements on the size of each component. For units with different cooling tons, the size of the main components such as compressors, condensers, and evaporators will change greatly, and the frequency converter will be affected by factors such as size and power. Large-scale revisions are required for device selection and structural design. Therefore, the scope of application of each frequency converter will be limited to several centrifuge units. Due to the variety of inverter models, the workload of R&D personnel will be doubl...
