Products knowledge

The thin one is the high pressure intake pipe and the thick one is the low pressure pipe. The pipeline of automobile air conditioner mainly has three sections: the pipe between the inlet and outlet of the compressor and the pipe between the condenser and the expansion valve.

The pipes at the inlet and outlet of the compressor are all equipped with a rubber pipe for shock absorption. The thicker one is the low-pressure pipe (the surface temperature of the compressor is low, and condensed water is visible), and the thinner one is the high-pressure pipe ( When the compressor is working, the temperature is high and it is a little hot.

The condenser to the expansion valve is a very thin aluminum tube. The temperature of the refrigerant coming out of the condenser is low, but the pressure attenuation is small, so it can also be called a high-pressure tube. There are also two joint diameters, which can be used to rotate the compressor main shaft. , judging from the method of gas inlet and outlet of the two interfaces.

It can also be identified by the letters next to the compressor connector. The joints of some compressors are mostly marked with S or D to distinguish them. S is a low-pressure joint and D is a high-pressure joint.

Car Air Conditioning Compressor:

1. The automotive air-conditioning compressor is the heart of the automotive air-conditioning refrigeration system and plays the role of compressing and transporting refrigerant vapor. There are two types of compressors: non-variable displacement and variable displacement. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

2. According to different working methods, compressors can generally be divided into reciprocating and rotary types. Common reciprocating compressors include crankshaft connecting rod type and axial piston type. Common rotary compressors include rotary vane type and scroll type. Mode.

3. Chinese name Automobile air-conditioning compressor Status The heart of the automobile air-conditioning refrigeration system Compresses and transports refrigerant vapor Classification Invariable displacement and variable displacement. The automotive air-conditioning compressor is the heart of the automotive air-conditioning refrigeration system and plays the role of compressing and transporting refrigerant vapor.

4. Compressors are divided into two types: non-variable displacement and variable displacement. Air-conditioning compressors are generally divided into reciprocating and rotary types according to their internal working methods. According to different working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors.

5. The displacement of the fixed displacement compressor increases proportionally with the increase of the engine speed. It cannot automatically change the power output according to the cooling demand, and has a relatively large impact on the engine fuel consumption. Its control generally collects the temperature signal of the air outlet of the evaporator.

6. When the temperature reaches the set temperature, the electromagnetic clutch of the compressor is released, and the compressor stops working. When the temperature rises, the electromagnetic clutch is engaged and the compressor starts to work. The fixed displacement compressor is also controlled by the pressure of the air conditioning system. When the pressure in the pipeline is too high, the compressor stops working.

7. The variable displacement compressor can automatically adjust the power output according to the set temperature. The air-conditioning control system does not collect the temperature signal of the air outlet of the evaporator, but controls the compression ratio of the compressor according to the change signal of the pressure in the air-conditioning pipeline to automatically adjust the air outlet temperature. In the whole process of refrigeration, the compressor is always working, and the adjustment of the refrigeration intensity is completely controlled by the pressure regulating valve installed inside the compressor.

8. When the pressure at the high-pressure end of the air-conditioning pipeline is too high, the pressure regulating valve shortens the piston stroke in the compressor to reduce the compression ratio, which will reduce the refrigeration intensity. When the pressure at the high pressure end drops to a certain level and the pressure at the low pressure end rises to a certain level, the pressure regulating valve increases the piston stroke to improve the refrigeration intensity.
