Diagnose and detect ac problems

The system of car air conditioner is an individual sealed circulatory system. It is related to the comfort of the ride, the economy and the safety of the car which is operate normally. To check the air conditioning system of the car.First, you must be familiar with it and understanding the air-conditioning system of the car, master its refrigeration principle, system configuration, structure, function, etc.; and be proficient in the interrelationship and the function of configuration; It is aware of the various possible or easy to produce Symptoms, it causes and troubleshooting methods of the failure.

Inspecting and the testing of refrigeration compressors:
The refrigeration compressor is the heart of the system of automobile air-conditioning. It is responsible for the compression and circulation of the system’s refrigeration working fluid. Usually it should be check and test for compression efficiency and leakage.

To test the compression efficiency of the compressor, without disassembling the system, it is necessary to connect a three-way pressure gauge set for testing.

When there is a certain amount of refrigerant in the system, the engine accelerates. At this time, the pointer of the low-pressure gauge should obviously drop, and the high-pressure pressure will also rise significantly. The greater the throttle, the greater the drop of the pointer, indicating that the compressor is performing well; if it accelerates The low pressure meter pointer drops slowly and the drop rate is not large, indicating that the compression efficiency of the compressor is low; if the low pressure meter pointer basically does not reflect when accelerating, it means that the compressor has no compression efficiency at all.

The most vulnerable part of the compressor to leak is the shaft seal (Oil seal). Since the compressor often rotates at high speed and the temperature of operating is high, the shaft seal is prone to leakage. When there are oil traces on the clutch coil and suction cup of the compressor, the shaft seal will leak definitely.
The main reasons that easily cause compressor damage are:
1. The air conditioner system is not clean, and particulate impurities are sucked in by the compressor;
2. Excessive refrigerant or lubricating oil in the system causes damage to the compressor by “liquid hammer”；
3. The temperature of compressor operating is too high or the operating time is too long;
4. The compressor is short of oil and is severely worn;
5. The electromagnetic clutch of the compressor slips and the friction temperature is too high;
6. The power configuration of the compressor is too small;
7. The manufacturing quality of the compressor is defective.
