How to put in excess car refrigerant

In the scorching summer, I believe everyone will continue to live with the air conditioner, but in addition to the high-frequency use of air conditioners in summer, it is also a season where air-conditioning problems erupt in large numbers. Once the air conditioner fails to cool down, you will never understand it without personal experience.

In the case of vehicle air-conditioning refrigerant leakage failure, many friends will not calculate the capacity of the vehicle when filling the refrigerant by themselves, which causes the phenomenon of overfilling the refrigerant. So what should I do when the car refrigerant is added?

How to release the car refrigerant?

Regarding the emission of automobile refrigerant, the most formal operation is to recycle it through the automobile refrigerant recovery and addition machine.Specific steps are as follows:

Ready to work:Before discharging the recycled refrigerant, prepare an automobile refrigerant recycling and filling machine and a refrigerant tank with sufficient remaining capacity.

Connecting pipeline:Connect the pipeline of the automobile refrigerant recovery and filling machine to the high and low pressure pipes of the automobile air conditioner (the red connects the high pressure pipe and the blue connects the low pressure pipe).

Recycling refrigerant:After the pipeline connection is correct, and the refrigerant recovery and filling machine has completed its self-checking, set the capacity of the refrigerant to be recovered and start the recovery. At this time, the automobile refrigerant recovery and filling machine will automatically start to discharge the excess refrigerant. Recycle.

Of course, since there is a formal method, there is an informal method. The informal method is to directly discharge the refrigerant into the atmosphere through the air-conditioning high-pressure pipe valve. However, since the direct discharge of refrigerant is not good for environmental protection, and there is also a certain degree of danger, we do not recommend that you do this.

Summarize:

Regardless of whether it is adding refrigerant or discharging refrigerant, this requires special addition and recovery tools. At the same time, the operator must have a certain basis for automobile air-conditioning. Therefore, we always recommend that you go to the 4S shop to deal with it. If you do it yourself, it will be self-defeating.
