Classification of Automotive Air Conditioning Systems

Classification of automobile air conditioning systems (by power source)

1. Non independent air conditioning: an air conditioning system that directly uses the driving power (engine) of the car to operate. The compressor of the non independent air conditioner is driven by the main engine and controlled by the electromagnetic clutch. When the power is turned on, the clutch of the automobile air conditioner is disconnected, and the compressor stops, 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 arrangement, and low noise.

The power consumption of main engine is 10% - 15%, which directly affects the acceleration performance and climbing ability of the vehicle. At the same time, its cooling capacity is affected by the vehicle speed. If the vehicle stops running, its air conditioning system also stops running.

However, non independent air conditioners have gradually become the leading products in the market due to their low cost (relatively independent air conditioners) and reliable quality. At present, most cars, minibuses and minibuses use this air conditioner. At present, the air conditioner is not independent.

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 transport, highland board buses and other vehicles. Independent air conditioners require two engines, which result in high fuel consumption and high costs, and their repair and maintenance are very difficult. They require very skilled engine maintenance personnel, and it is difficult to obtain engine parts, especially imported engines; In addition, the design and installation are more likely to cause system quality problems, and the additional drive engine increases the probability of failure.
