There are many types of automotive air conditioning compressors, including fixed displacement compressors, variable displacement air conditioning compressors, crankshaft connecting rod compressors, axial piston compressors, rotary vane compressors, and scroll compressors. 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.

First of all, if the car owner has any abnormal noise and is unsure, it is recommended to go to the 4S shop for repair in time. If you ignore it, the abnormal noise will become louder and louder. When the bearing is broken and the axis is crooked, you may have to replace the entire air conditioning system when you repair it. Secondly, during the operation of the air conditioning compressor, it is a common phenomenon that the compressor gets stuck. The main reason for the jam is poor lubrication. When there is a lack of lubricating oil, it is necessary to pay attention to it, because serious abnormal noise may be generated inside the compressor, and even cause the compressor to be worn and scrapped. In this case, you should check whether the clutch is slipping or the conveyor belt is problematic. In addition, the repeated engagement of the electromagnetic clutch can also cause abnormal noise in the compressor.
