Working principle of automobile compressor
Working principle of automobile air-conditioning compressor The compressor of the automobile air-conditioning system is directly driven by the engine, which is realized by a belt drive mechanism. When the compressor is not working, the compressor can be disconnected from the engine, which is achieved by an electronic clutch. When the air conditioning system stops working, you should always check the tightness of the belt to determine whether the clutch is operating correctly. Sometimes the clutch affects the compressor shaft seal due to damage to the bearing, causing refrigerant leakage at the compressor shaft seal.
The working principle of a fixed-displacement compressor is to increase in proportion to the engine speed. This kind of compressor cannot automatically output the 100-year power according to the demand of air conditioning and refrigeration during operation. At the same time, it uses The fuel consumption of the engine is relatively large. The fixed displacement compressor also collects the temperature of the evaporator air outlet. When the temperature reaches the set value, its compressor electromagnetic clutch will be released, and the compressor will stop working. The variable displacement compressor is just like the inverter air conditioner in the household air conditioner. It can automatically adjust the output power according to the set temperature. The air conditioning control system does not need to collect the temperature of the evaporator outlet, but through the pressure in the air conditioning pipeline The speed of the compressor is adjusted to adjust the temperature of the air outlet. The compressor has been working throughout the whole process. The cooling strength of the air conditioner is all controlled by a pressure regulating valve installed inside an old compressor.
