How to judge when car air conditioners need to add fluorine
Judge when car air conditioners needHow to add fluoride When the air conditioner is working normally, there are still bubbles in the glass hole, indicating that the amount of fluorine is in short supply and needs to be increased. When the air conditioner is working normally, there are no bubbles in the glass hole. When the air conditioner is stopped, there are no short bubbles, indicating that the amount of fluorine is large and needs to be discharged.
There are two ways to add fluoride to car air conditioners. One is high-pressure end filling, which is suitable for filling after leak detection and vacuuming. Please note that the compressor must not be turned on in this method, the engine must be stopped, and the refrigerant tank must be turned upside down. The other is filling at the low-pressure end, which is filled with gas and the filling speed is slow.
Judge whether fluoride is needed through the liquid microscope of the liquid storage dryer. When the air conditioner is working normally, bubbles continue to appear in the liquid mirror, indicating that the amount of fluoride is insufficient and needs to be increased; if there is a large amount in the liquid mirrorFoam indicates that the fluoride is seriously insufficient, and it is necessary to check the leakage, repair the leakage site, and add an appropriate amount of fluoride.
Car fluorination is to protect the performance of the air conditioning system and extend its service life. In order to judge whether fluorine is needed, it is necessary to observe the working condition of the car air conditioning system first. If the refrigeration effect of the air conditioner is significantly reduced, the temperature cannot reach the set value, or the refrigeration time becomes longer, it is likely that fluorine needs to be added.
Fluorine is a kind of refrigerant, which is the basis for the refrigeration of automobile air conditioning. There will also be some losses in the process of driving, so automobile air conditioners also need to be fluorined. However, there is no strict regulation on the cycle of fluoridation of car air conditioners. Under normal circumstances, it can also be added every 2 to 3 years. The time of fluoridation can also be judged according to the refrigeration of car air conditioners.
What is the fluoridation tutorial for car air conditioners?
The following steps are required for fluorination of car air conditioners: Confirm whether the air conditioning system needs to be fluoridated. If the air conditioning system has problems such as poor refrigeration effect and extended refrigeration time, fluorine may need to be added. Confirm the amount of fluoridation. The amount of fluorine can be determined by checking the pressure of the air conditioning system. In general, it needs to be checked on the pressure gauge.
First, start the car, turn on the AC switch, turn on the blower to the maximum, and wait for three minutes to put the fluorine tube into the fluorine nozzle.
The method of fluorination of car air conditioners is as follows: a DIY filling tube for car air conditioners. A bottle of R134A refrigerant 250 grams is fine. Now start to test the pressure of the car: first, rotate the thimble at the end of the DIY supplementary tube bottle opener counterclockwise to the top, and then screw the refrigerant bottle into the bottle opener and tighten it.
Prepare a complete and qualified refrigerant filling tool. Connect the car air conditioner and the filling tool to adapt the connector. Vacuum. Inject liquid refrigerant from the high-pressure side, so as to complete the fluorination of the car air conditioner. The phenomenon of fluorine deficiency in the air conditioner: the low-pressure pipe (thick pipe) is dry and touched by hand, and there is no feeling of ice.
Steps for adding fluorine at the low-pressure end: First, connect the manifold pressure gauge to the compressor and refrigeration tank, open the refrigerant tank, loosen the nut injected into the middle hose on the manifold pressure gauge until you hear the sound of refrigerant steam flow, and then tighten the nut to drain the air injected into the hose.
The fluorination of automobile air conditioners needs to be carried out using a Freon filling meter, and the refrigerant is added through the meter on the low-pressure side. The specific operation steps are as follows: understand the filling meter to the high-pressure and low-pressure ports of the vehicle.Connect the storage tank of refrigerant. Open the valve of the filling meter. Start the vehicle engine and turn on the air conditioning system.

The method of car air conditioner fluorination is as follows: a car air conditioner DIY filling and replenishment tube. A bottle of R134A refrigerant 250 grams is fine. Now start to test the pressure of the car: first, rotate the thimble at the end of the DIY supplementary tube bottle opener counterclockwise to the top, and then screw the refrigerant bottle into the bottle opener and tighten it.
Before adding fluorine, first of all, it is necessary to confirm whether there is leakage, and check the high and low pressure with the manifold pressure gauge assembly. If it is found that its cooling effect is poor during use, it should be checked. The fault is generally caused by refrigerant leakage. Before adding fluoride, first check whether there is a leak, and check the high and low pressure with the manifold pressure gauge assembly.
First, start the car, turn on the AC switch, turn on the blower to the maximum, and wait for three minutes to put the fluorine tube into the fluorine nozzle.
The commonly used method of filling fluorine in automobiles is to operate through the low-pressure filling system. First of all, it needs to be connected to the air conditioning system through the low-voltage port. Then, by mastering the appropriate amount of fluorine, the fluorine gas is slowly injected into the air conditioning system until the specified pressure or weight is reached.
Prepare a complete and qualified refrigerant filling tool. Connect the car air conditioner and the filling tool to adapt the connector. Vacuum. Inject liquid refrigerant from the high-pressure side, so as to complete the fluorination of the car air conditioner. The phenomenon of fluorine deficiency in the air conditioner: the low-pressure pipe (thick pipe) is dry and touched by hand, and there is no feeling of ice.
Judge the empty carThe method of adjusting when fluorine is needed is as follows: When the air conditioner is working normally, there are still bubbles in the glass hole, indicating that the amount of fluorine is lacking and needs to be increased. When the air conditioner is working normally, there are no bubbles in the glass hole. When the air conditioner is stopped, there are no short bubbles, indicating that the amount of fluorine is large and needs to be discharged.

The process of air conditioning fluorination: start the car and turn on the car air conditioning system;Wait for 5-10 minutes after turning off the ignition to stop the air conditioning system completely; make a deflating sound from the outside and add Freon.
First, connect the manidifold pressure gauge to the compressor and the refrigeration tank. Open the refrigerant tank, loosen the nut injected into the middle hose on the manifold pressure gauge until you hear the sound of refrigerant steam flow, and then tighten the nut to discharge the air injected into the hose. Open the low-pressure manual valve to let the refrigerant enter the refrigeration system.
First, start the car, turn on the AC switch, turn on the blower to the maximum, and wait for three minutes to put the fluorine tube into the fluorine nozzle.

The thimble in the end of the DIY supplementary tube bottle opener rotates counterclockwise to the top. To find the low-voltage interface, there is generally a small blue or black hat at the left end under the hood. There is an L on the hat, and the small hat is screwed down. Start the car engine and turn on the air conditioner AC switch.
