The technology of realizing AC control by changing the frequency of AC is called frequency conversion technology.
The core of the DC frequency conversion technology is the frequency converter, which realizes the automatic adjustment of the operating speed of the compressor through the conversion of the power supply frequency, and changes the fixed grid frequency of 50 Hz to a variable frequency of 30-130 Hz.
At the same time, it also makes the power supply voltage adaptable to 142-270V, so the DC frequency conversion technology can adjust the power output of the compressor in a wider range, and can adapt to a wider range of grid voltage fluctuations.
The flexible frequency conversion technology is to adjust the power supply frequency through the frequency converter, so that the power frequency of 50HZ is converted into 30~60HZ, and the compressor adopts a dual-frequency compressor, so as to realize the frequency conversion adjustment of the cold dryer and obtain a wide range of compressor output power adjustment.At the same time, the soft start mode starts the compressor at a low frequency, which reduces the starting current of the compressor, reduces the loss of the compressor, and prolongs the stability and service life of the compressor.
In addition, the perfect cooperation of the scroll compressor with excellent performance and the frequency converter is adopted. When the load of the compressor changes greatly and liquid refrigerant enters the compressor, it can adapt to the liquid compression to prevent the compressor from being damaged.
