The automotive air-conditioning compressor system is a device that realizes cooling, heating, ventilation and air purification of the air in the cabin. It can provide a comfortable riding environment for passengers, reduce the driver's fatigue strength, and improve driving safety. The air conditioning unit has become one of the indicators to measure whether the car is fully functional.

Types of Automotive Air Conditioning Compressor Systems

1. According to the driving mode, it is divided into: independent type (a dedicated automobile air-conditioning compressor clutch drives the compressor, with large cooling capacity and stable operation, but high cost, large volume and weight, mostly used for large and medium-sized passenger cars) and non-independent type (The clutch of the automobile air-conditioning compressor is driven by the automobile engine, the refrigeration performance is greatly affected by the engine work, and the stability is poor, and it is mostly used in small passenger cars and cars).

2. According to the performance of air conditioning, it is divided into: the first single function type (the refrigeration, heating and ventilation systems are installed and operated separately, without interfering with each other, and are mostly used in large passenger cars and trucks) and the heating and cooling integrated type (refrigeration, heating, ventilation) The blower and air duct are shared and controlled on the same control panel. When working, it can be divided into a combined type in which the cold and warm air can work separately, and a mixed temperature adjustment type in which the cold and warm air can work simultaneously.

According to the control mode, it is divided into manual type (toggle the function keys on the control panel to control the temperature, wind speed and wind direction) and electro-pneumatic adjustment (using the vacuum control mechanism, when the air conditioning function key is selected, it can be automatically adjusted within a predetermined temperature) control of temperature and air volume).

3. According to the control method, it is divided into: automatic adjustment (using the calculation and comparison circuit to control the work of the adjustment mechanism through the clutch signal of the automobile air-conditioning compressor and the pre-adjustment signal, and automatically adjust the temperature and air volume) and the automatic adjustment controlled by the microcomputer (using the microcomputer as the The control center realizes all-round and multi-functional optimal control and adjustment of the air environment in the vehicle).

Arrangement of the air conditioning system

Different types of air conditioning systems are arranged differently. At present, the most widely used air conditioning system in cars is the cooling and heating integrated air conditioning system. Its layout type is to assemble the evaporator, warm air radiator, centrifugal blower, operating mechanism, etc., which is called the air conditioner assembly.

Components of a car air conditioning system

Modern air conditioning system consists of automobile air conditioning compressor, automobile air conditioning compressor clutch, refrigeration system, heating system, ventilation and air purification device and control system.
