The automobile air conditioning compressor is the core component of the automobile air conditioning system. In recent years, my country’s automobile industry has developed rapidly, which has also promoted the development of my country’s automobile air-conditioning compressor industry.
Working principle of automobile air conditioning compressor controller and power board
The automotive electric air conditioning compressor is a component used to provide refrigeration and heating functions in electric vehicles. It replaces the internal combustion engine in traditional fuel vehicles. Compared with traditional air conditioning compressors, electric air conditioning compressors have higher energy efficiency and lower noise, and are also easier to maintain and install.
The operating principle of an electric air conditioning compressor is to use an electric motor to drive the rotor of the compressor to rotate, compressing and transporting the refrigerant to the condenser and evaporator, thereby achieving the functions of cooling and heating. In electric vehicles, the electric air conditioning compressor is usually powered by a power battery.
In order to ensure the normal operation and control of the motor, the capacitor can store electrical energy, filter out harmonics in the line, and play a key role in the stable operation of the entire machine.
