Classification of automotive air conditioning systems (by power source)

1. non independent air conditioning: an air conditioning system that directly uses the driving power (engine) of the vehicle to operate. The non independent air conditioner is driven by the main engine to run the compressor and controlled by the electromagnetic clutch. When the power supply is connected, the clutch of the car air conditioner is disconnected, and the compressor is stopped, so as to regulate the supply of cold air and control the temperature in the compartment. The utility model has the advantages of simple structure, convenient installation and layout, and low noise.

Because it needs to consume 10%-15% of the power of the main engine, it directly affects the acceleration performance and climbing ability of the vehicle. At the same time, the cooling capacity is affected by the vehicle speed. If the vehicle stops running, the air conditioning system will also stop running.

Nevertheless, non independent air conditioners have gradually become the leading products in the market due to their low cost (relative to independent air conditioners) and reliable quality. At present, most cars, vans and minibuses use this air conditioner. At present, non independent air conditioners.

2. independent air conditioning: there is a special power source (such as the second internal combustion engine) to drive the operation of the entire air conditioning system. It is generally used for long-distance freight transportation, highland board buses and other vehicles. Due to the need for two engines, the independent air conditioner has high fuel consumption and high cost, and it is very difficult to repair and maintain. It requires very skilled engine maintenance personnel, and engine accessories are not easy to obtain, especially imported engines; In addition, the design and installation are more likely to lead to system quality problems, and the additional drive engine increases the probability of failure.
