The difference in understanding the inverter air conditioner is that the compressor and the electronic control system are different.

       The compressor of the DC inverter air conditioner uses a DC motor, and the electronic control system is more complicated, which is attributed to synchronous control. The compressor of the inverter air conditioner uses a communication motor. The electronic control system is relatively simple, which is attributed to asynchronous control. DC inverter air conditioner saves 20%~30% of electricity than communication inverter air conditioner. DC frequency conversion is better than communication frequency conversion in terms of comfort, mute, life, and control accuracy.

       1. Communication frequency conversion skills The operation principle of communication frequency conversion air conditioners is: frequency conversion skill is a skill that changes the power frequency through the frequency converter and then changes the speed of the compressor. After the frequency converter, the conversion from communication to DC is performed first, and then the frequency converter is converted from DC to communication, and then the speed of the communication motor is controlled. The control of the inverter is to transmit the indoor temperature information to the microcomputer through the sensor, output a waveform with a certain frequency change, and control the frequency of the inverter. When the indoor temperature drops rapidly or increases rapidly, the indoor air conditioning load increases, the compressor speed increases, and the cooling capacity is added proportionally. On the contrary, when the indoor air conditioning load decreases, the compressor operates normally or decelerates. Communication Inverter compressors are essentially three-phase communication asynchronous motors, and the rotor rotates after the mutual effect of the magnetic field between the stator and the rotor. But its special planning makes it possible to change the speed of the motor by changing the frequency and voltage of the power supply of the control panel in a large range, so it is called communication frequency conversion. Features: Compared with fixed frequency air conditioners, the power of communication inverter air conditioners is higher, the noise is lower, and the control is sensitive. Its cost is lower than that of DC inverter air conditioner. Inverter air conditioner controller
       2. The principle of DC frequency conversion technology: The operation principle of DC frequency conversion air conditioner is to convert the 50Hz power frequency communication power supply to DC power supply and send it to the main circuit of the power module. The power module is also controlled by the microcomputer, the difference is that the module outputs It is a DC power supply with variable voltage, and the compressor uses a DC motor, so the DC inverter air conditioner can also be called a full DC variable speed air conditioner. The rotor of the DC inverter compressor is made of rare earth permanent magnet materials. Its operating principle is: the direct effect of the rotating magnetic field generated by the stator and the rotor permanent magnet magnetic field completes the compressor operation. It can change the speed of the motor by changing the DC voltage sent to the motor. The DC inverter air conditioner has no inverter link, which is more power-saving than communication frequency conversion in this regard. Features: There is no electromagnetic induction effect of the stator rotating magnetic field on the rotor of the DC inverter compressor. The control board overcomes the electromagnetic noise and rotor loss of the inverter compressor. The electronic control board has higher power and lower noise than the inverter compressor. Characteristic, the power of DC inverter compressor is 10%-30% higher than that of communication inverter compressor, and the noise is 5dB-10dB. However, the cost of DC inverter air conditioner is higher than that of communication inverter air conditioner.
