Which Is Best AC Compressor In Car?

There are many types of compressors, including fixed displacement compressors, axial piston compressors, scroll compressors, etc. Different air conditioner compressors are suitable for different air conditioner systems.

It is important to know the A/C compressor types used in your car. This will save you from the disappointment of buying a compressor that doesn't work efficiently. In other words, the best compressor is the best one for your vehicle's air conditioning system.

Check the ac compressor

1. Check the tightness of the compressor: check with a branch pressure gauge, connect the high and low-pressure hoses of the branch pressure gauge to the high and low-pressure inspection valve of the compressor, and start the engine to run at idle speed.
2. Measurement of the resistance value of the electromagnetic clutch of the compressor: first remove the coil of the electromagnetic clutch from the compressor, and then measure its resistance value with a multimeter. In order to avoid measurement errors, the dial of the meter should be blocked. If the meter pointer does not move during measurement, it means that the electromagnetic clutch coil has a new circuit. If the measured value is less than 350, the coil is shorted, or the solenoid should be replaced.
3. Check the running status of the compressor: whether the drive belt is broken or loose. If the drive belt is too loose, it will slip, accelerate wear and fail to transmit power. Whether there is noise inside the compressor, and whether the compressor clutch is slipping.

The symptoms of quality ac compressor in car

1. Sound: The sound of different types of air conditioner compressors with excellent performance is generally relatively small, and there will be no loud noise or abnormal sound.
2. When the air conditioner is running, the air volume of the air outlet is also a way to measure the quality of the compressor. If the air volume is stable, the temperature in the car is balanced, and there is no difference between the temperature and the air volume of each air outlet. And there is no jitter, indicating that the quality of the air conditioner compressor is good.
3. The temperature inside the car changes rapidly while using it. The refrigerant flow rate in the system varies greatly.
4. Because the air conditioner compressor needs to use refrigerant to convert heating into cold air. If there is no refrigerator, the air conditioner will blow warm air. If the refrigerator is using the correct amount and there are no leaks, it is working properly.
