What kind of pipe does the car air conditioner suppress? How much does the car air conditioner suppress?

For automobile air-conditioning failures, refrigerant leakage occupies most of the causes. Generally, after we investigate and solve the leakage problem, we need to check whether the air-conditioning system still has a leakage problem through a pressure test. Then, what is the control of the car air-conditioning suppression? How much pressure should we hit?

What kind of control does the car air conditioner suppress?

Under normal circumstances, the suppression of automobile air conditioners is done by pressing high-pressure pipes; for vacuuming, it is done through low-pressure pipes.

How much is the suppression of car air conditioning?

Under normal circumstances, the suppression of car air conditioning will generally hit about 20-30 Bar. If the air conditioner pressure can be stabilized at 20-30Bar, it means that the air conditioner leakage problem has been solved, and the car air conditioner has good sealing performance, and then the air conditioner can be vacuumed and added refrigerant.

About adding refrigerant to air conditioner

After the pressure test and vacuum pumping are completed, we can directly add refrigerant. To add refrigerant, set the filling capacity, time and type on the refrigerant recovery and filling machine according to the maximum capacity of the refrigerant marked on the vehicle air conditioner. After confirmation, the refrigerant recovery and filling machine can automatically start adding refrigerant.
