How often do you add car refrigerant, and how do you add more car refrigerant?

Many people don't know how often the car refrigerant is added, or even do not know that the car needs to add this kind of thing. There are also some friends who think that the car refrigerant needs to be replaced regularly, but this is not the case. How about it, let’s get to know it together.

Automobile refrigerants are also called automobile refrigerants, commonly known as refrigerants. They are divided into environmentally friendly R 134a and non-environmentally friendly R12. Because R12 has serious damage to the atmospheric ozone layer and produces a greenhouse effect, endangering the environment on which humans depend. Restricted and prohibited. Today's car air conditioners are mostly environmentally friendly, and more use R134a refrigerant.

There is no fixed cycle for the filling of automobile refrigerant. It is mainly based on whether the cooling effect of the automobile is good or bad to determine whether it needs to be filled. If the cooling effect is normal, it does not need to be filled. There are many types of air conditioners used in existing cars, and their structures are similar. The maintenance interval should generally be once a year or as needed.

During useFindWhen the cooling effect of the air conditioner is not good, it should be checked. The failure is usually caused by the leakage of refrigerant. This is because the air conditioner may have leaks, and the air conditioner pipes or condensers have slight leaks, which will accelerate the loss of refrigerant. Even if the refrigerant does not leak, there will be natural loss. Generally, it needs to be refilled every 2-3 years. Generally, there is no problem with car air conditioners, and there is no need to add refrigerant within 3 years.

There is also a measure for auto refrigerant refilling. Too much is not good, and too little will not achieve the effect, so we need to pay attention to it. What if the car refrigerant is added too much? The refrigerant can be directly discharged into the atmosphere through the air-conditioning high-pressure pipe valve, but if it is R12 refrigerant, the direct release is not environmentally friendly, and there is still a certain degree of danger, so this is not recommended. The most formal operation is to recycle through the car refrigerant recycling and adding machine: connect the car refrigerant recycling and filling machine pipeline to the high and low pressure pipes of the car air conditioner (red high and blue low), set the required refrigerant capacity to be recycled, and start the machine recycling That's it.

It should be noted that whether it is filling or discharging, you need professional tools and certain skills. It is recommended that you go to a professional repair shop or 4s shop for operation, which is more professional and safer.
