The car has been used for a long time, and when the air conditioner is used in the summer, it willdiscoverThe cooling of the air conditioner has deteriorated, which is mostly caused by insufficient refrigerant in the air conditioner. Air-conditioning refrigerant is also called refrigerant, which is what we often call refrigerant or fluorine. When fluorine is insufficient, it needs to be replenished in time. So, let’s take a look at the video tutorial on how long to add fluoride to the car air conditioner and how to add fluoride to the car air conditioner.
How long does the car air conditioner add fluoride
There is no fixed cycle for the refilling of fluorine in automobile air conditioners, and it is mainly based on the performance of the vehicle's refrigeration effect to determine whether it needs to be refilled. In the course of use, when the cooling effect of the air conditioner is found to be poor, an inspection should be carried out. The faults are generally caused by fluorine leakage. This is because the air conditioner may have leakage, and the air conditioner pipeline or condenser has slight leakage, which will accelerate the loss of fluorine. Even if there is no leakage, there will be natural wear and tear. Generally, it needs to be refilled every 2-3 years. However, there is no problem with general car air conditioners, and there is no need to add fluorine within 3 years.
There are two ways to add fluoride to automobile air conditioners, namely high-pressure side filling and low-pressure side filling. The high-pressure end is filled with liquid, which is safe and fast, and is suitable for the first filling of the refrigeration system; the low-pressure end is filled with gas, and the filling speed is slow, which is usually used for replenishment. The following are the steps of adding fluoride at the low pressure end:
1. First connect the manifold pressure gauge with the compressor and refrigeration tank
2. Open the refrigerant tank, loosen the nut of the middle injection hose on the manifold pressure gauge until you hear the sound of refrigerant vapor flowing, and then tighten the nut to discharge the air in the injection hose.
3. Open the low-pressure manual valve to let the refrigerant enter the refrigeration system. When the pressure of the system reaches 0.4MPa, close the low-pressure manual valve.
4. Start the engine, turn on the air conditioner switch, and adjust both the blower switch and the temperature control switch to maximum.
5. Open the manual valve on the pressure gauge of the manifold and let the refrigerant continue to enter the refrigeration system until the filling volume reaches the specified value.
6. After filling the specified amount of refrigerant into the system, observe from the sight glass, if there is no air bubbles, it indicates that the filling is complete.
After the fluorine filling is completed, close the low-pressure manual valve on the manifold pressure gauge, close the injection valve installed on the refrigerant tank, stop the engine, and remove the manifold pressure gauge from the compressor. The action should be rapid when removing , So as not to leak too much refrigerant. The following is a specific fluoride video tutorial:
