ⅠCommercial Vehicle A/C Compressor Market
The compressor is a key component of the air conditioner and one of the decisive factors affecting the performance of the air conditioner.
The air-conditioning compressor is the heart of the refrigeration system, acting as a suction, compression and circulation pump. The compressor can be regarded as the interface between the low-pressure end and the high-pressure end of the refrigerant circuit. The refrigerant is sucked and compressed from the low-pressure side to increase its temperature and pressure, and then pumped into the high-pressure side, reciprocating.

Taking bus as an example, traditional passenger bus air conditioning systems mostly use mechanically driven piston compressors or screw compressors. Most of the new energy bus air conditioners use inverter horizontal scroll compressors. At present, most air conditioner manufacturers in China purchase imported horizontal inverter scroll compressors.

China's increasing demand for horizontal type electric compressors has provided market demand for scroll compressors. The continuous increase in demand ...
... has caused a shortage of supply for the inverter compressor.

Most of China's horizontal scroll compressors rely on imports. The main suppliers are: Emerson, Hitachi and Panasonic. As China’s current electric air-conditioning compressor technology is still immature, the power is small, and it takes a certain time to increase the output. At the same time, the price of imported compressors is relatively high. Therefore, the shortage of compressor supply will continue in the short term, which may affect the new The production capacity of energy vehicle air conditioners.

Passenger car air-conditioning compressors mainly include swash plate type, scroll type and rotary vane type.
1.The swash plate compressor is the leading product of the reciprocating compressor. It has been developed for many years and the technology is relatively mature. It is mainly used in large displacement passenger cars with high energy consumption.
2.Scroll compressors have no reciprocating motion, are more efficient, have low noise, and run smoothly. Compared with variable displacement swash plate compressors, they have lower cost and are more suitable for small displacement vehicles.
3.The rotary vane compressor is small in size and weight, easy to arrange in a small engine compartment, and is suitable for mini vehicles.

Ⅱ Electric Compressor Market
The electric compressor is powered by a battery, and the controller controls the motor speed, thereby controlling the cooling capacity and adjusting the temperature. The scroll compressor's high efficiency and high speed endurance determine that it is suitable for use with high-speed motors, and the electric control unit adjusts the speed of the motor to improve the energy efficiency of the air conditioning system. It is more suitable for use in electric vehicles and has a higher individual value.

Electric air-conditioning compressors are divided into two types according to the electric drive mode.
One is the all-electric compressor, which is driven only by electricity, and is divided into independent and non-independent according to the drive mode;
the other is the hybrid drive compressor. The engine and electric motor hybrid drive the compressor, which can switch between the engine drive mode and the electric drive mode to save energy consumption of the car.

Currently, stand-alone electric compressors are the main choice for existing new energy vehicles. For an independent all-electric air-conditioning system, the electric vehicle motor directly drives the air-conditioning compressor to cool, so that the air-conditioning compressor can run at the set optimal constant operating speed of the motor without being affected by the operating conditions of the entire vehicle. Generally, the compressor is not driven by a motor through a transmission belt. Coaxial drive schemes are generally adopted at home and abroad. This type of compact structure can adapt to more automotive platforms.

In the field of air-conditioning compressors for new energy vehicles, the required driving force is completely different, so the technical barriers are very high. Before 2015, Japanese companies completely monopolized the new energy vehicle air-conditioning compressor market, and even the old German manufacturer Bitzer Refrigeration could hardly compete with it, and the latter almost monopolized the global passenger car air-conditioning compressor market. After 2015, Chinese compressor companies began to make efforts, their technical strength gradually increased, and their market share gradually increased.
