What if the car air conditioner doesn't cool? The mechanic will give you four tips.

Now that it has officially entered the hot summer, friends who drive in hot weather will definitely use air conditioning. However, some people find that there seems to be something wrong with the air conditioning and refrigeration in their cars, and the refrigeration effect is not ideal or not. So what is the reason and what should I do? When the mechanic comes to give you four tips, don't waste money dealing with the problem that the air conditioner doesn't cool. Do you know when?

/No.KLOC-0/:The belt of air conditioner compressor is too loose. If you turn on the air conditioner in the car and find that you can hear the sound of "squeaking", then you should pay attention to the fact that the air conditioner is not cooling, and the compressor belt is probably loose. In this case, we need to tighten the belt of the air conditioner compressor. Also, this belt is made of rubber and has a certain service life. If it cannot be used after aging, it needs to be replaced.

Second: insufficient refrigerant. The code name of commonly used refrigerants is R 134A. The result of insufficient refrigerant is to affect the refrigeration effect of air conditioner and lead to insufficient refrigeration. Generally speaking, the environment in which the refrigerant is located is relatively closed. However, after the vehicle has been used for a long time, the parts in the air conditioning system may age and wear, and the space where the refrigerant is located will leak, so the amount of refrigerant is insufficient. So everyone should also pay attention to check this.

No.3: The air conditioner filter is too dirty. We also mentioned the important influence of air conditioning filter on the air we breathe and our health before. If the filter element is too dirty, it will not only cause a lot of impurities in the air inhaled into the car, but also block the filter element of the air conditioner, so that part of the cold air of the air conditioner is blocked, resulting in that we cannot feel the refrigeration of the air conditioner.

Fourth: the condenser is too dirty. If the condenser is not cleaned and all kinds of impurities are tightly wrapped, the condenser will not be able to dissipate heat normally. This is also one of the reasons why the air conditioner does not cool. Seeing this, I believe that everyone has an understanding of the reasons and solutions for the non-cooling of the air conditioner in the car.
