Today I will share with you two failures of car air conditioners! 1. It is said that there is an 18-year-old car that has driven a total of 30,000 kilometers. Today, I went out to play on Ching Ming Festival. Turned on the air conditioner. I just started to drive for a while under the cooling system. I heard a squeaking sound, and then I saw the front hood. Smoke, and then the red battery indicator on the dashboard lights up!
After opening the hood, it was found that the belt was broken. Later, after the inspection by the maintenance master, the air conditioner compressor was locked and the belt was broken! Think about it, it’s okay to not turn on the air conditioner at the beginning. This problem occurred after a few minutes after turning on the air conditioner. It must be related to the air conditioner! (This is the first time the air conditioner is turned on this year)
2. There is another car, which is also a new car. It was just picked up when the winter entered, and after a few days, it rear-ended another car. The front bumper of this car, the condenser was injured and damaged, and the air-conditioning refrigerant leaked. Because it is winter, repair it In the process, the repair shop replaced a new condenser and suppressed the experiment, but because it was winter, the temperature was too low and the car air-conditioning refrigerant was not charged. This has not been used for almost half a year, and it is not summer. I am going to charge it with refrigerant. The air conditioner was used, but the repair shop informed that the air conditioner compressor was broken!
The owner said: shouldn't it, my car is only one year old, why is the air-conditioning compressor broken?
What causes the "new" compressor to be so prone to problems?
1. When the heater is turned on in winter, the air conditioner may have been working with it, but I didn't notice it!
As we all know, the front windshield is prone to fogging in winter. Air conditioners are sometimes used for defrosting in winter. Now many models will automatically turn on the air conditioner when blowing the glass. If it is in winter, when the glass is first blown, it may be air-conditioned when using warm air. Has been working, does this greatly reduce the service life of the compressor!
2. If the car causes refrigerant leakage due to various reasons, there is no refrigerant inside the compressor, which will increase the wear and tear of the compressor, which will form a hidden danger. The final result is that the air-conditioning compressor locks up!
Air-conditioning refrigerants are also oily and will also play a role in lubricating the compressor. Experiments have shown that if there is no refrigerant in the inverter air-conditioning compressor, the compressor is more likely to be damaged!
3. At present, many new cars have various air conditioning control methods. Many cars use can line transmission instead of a direct power switch. It is a signal transmitted to the computer. The computer analyzes the signal to make a decision. This transmission One drawback of this method is that the switch cannot be used frequently, which will cause slow response and inaccurate signal analysis! Just like the phone crashes, the operation speed is too fast and it may get stuck!
Because the computer receives the signal and analyzes the signal to make a decision, there is a process, so sometimes you watch the air conditioner Ac turn off, maybe the compressor is still working, if you don’t know it, it may have been working, and it will be out after a long time. problem!
4. Of course, the air conditioner pressure is too high, the fan heat dissipation problem will cause the air conditioner compressor to be damaged in advance, but the above three reasons are that new cars often appear, so be careful!
The above four reasons are the ultimate cause of damage to the compressor, especially the first three are mainly for new models in recent years. Of course, the compressor itself cannot be ruled out. You must pay attention when driving!
Thank you all for reading! Thank you
