New Energy Vehicle Air Conditioning Compressor, Zhengzhou

Air-conditioning compressors for new energy vehicles refer to compressors used in vapor compression refrigeration and heating systems in new energy electric vehicles, which provide power for the circulation of working fluid in refrigeration and heating systems, and are driven by the compressor's own motor. The refrigerants used mainly include R134a, R1234yf, R410A, R407C and CO2.
Due to the change of the driving mode, the main technical characteristics and performance requirements of the new energy vehicle air-conditioning compressor are as follows:
(1) High efficiency, low noise, light weight, and miniaturization.
(2) Adapt to more stringent operating conditions and wider operating range.
(3) High security and reliability.

Electric scroll compressors are generally used in the new energy vehicle industry. This type of compressor has the following advantages: (1) There is no suction valve and no clearance volume, so the volumetric efficiency is high.
(2) The multi-chamber scroll compressor works continuously, the torque pulsation is small, and the compressor works smoothly; there is no suction valve, which reduces the noise source caused by the suction valve, and the noise is low; the turning radius of the moving plate is small, and the shaft The system is easy to achieve dynamic balance and has little vibration.
(3) There are few moving parts, the relative motion speed of the movable and static scrolls is low, there is little friction and wear, the mechanical efficiency is high, and the reliability is improved.
The air-conditioning compressor market is dominated by foreign-funded companies, such as Sanden, Denso, Valeo, Hanon, etc. Since my country’s electric vehicle market le
