Does the refrigerant of the air conditioner on the car leak

The refrigerant filling should be carried out after vacuuming, and there are four filling methods: weighing filling method, gauge pressure filling method, empirical filling method and quantitative filling method. (1) Weighing and filling method.

The weighing and filling method is a filling method that uses electronic scales to weigh the scale. To operate, place the refrigerant cylinder on the tray of the scale. and connect the filter drier, the liquid dosing pipe and the three-way valve, put the air in the connecting pipe, weigh the weight, subtract the amount of refrigerant that needs to be charged, write down the remaining weight, and then slowly fill the refrigerant until the scale.

The upper can be consistent with the remaining quantity, (2) gauge pressure filling method.

The gauge injection method uses the low-pressure suction pressure of the refrigeration circulation system to determine the amount of charge. When operating, the refrigerant cylinder can be filled by connecting the filter drier, connecting pipe, three-way valve and vacuum pressure gauge, observing the indication value of the pressure gauge when filling, when the pressure is expressed, close the three-way valve to let the compressor run, when the pressure gauge drops to 0, open the three-way valve again, adjust the pressure section time, until the suction pressure is stable and unchanged. (3) Empirical abution method.

The empirical filling method is a method of determining the amount of filling according to the cooling situation of the air conditioner. The connection method is the same as the gauge pressure filling method, when the refrigerant is filled to the vacuum pressure gauge value, close the three-way valve, and run for 30 minutes until the compressor suction pipe is condensed. (4) Quantitative dosing method.

The timing filling method is a method that uses the filler to fill according to the rated filling volume of the air conditioner. Select the appropriate scale of the graduated cylinder, open the corresponding valve, let the refrigerant flow into the graduated cylinder, when the refrigerant reaches the selected scale, open the filler valve, so that the refrigerant in the graduated cylinder flows into the refrigeration system. This method is accurate and applicable to on-site maintenance.

4 bottles of R134 refrigerant to see how many milliliters, this car only adds 680 grams, if it is not good after a month of repair, you don't have to pay rice for repairs again (4S shop) outside it is difficult to say. However, there is a little leakage is very time-consuming, you had better go to the 4S shop to check the guarantee, it is best to add fluorescence in the air conditioning system so that you can find out whether there is a leak or not, there is no best, if there are a few leaks, the car is easy to leak, and there is an accident repair is repaired at the maintenance station, if it is repaired outside, it is the best to add fluorescent energy, and it is done at one time.

If it is slow leakage, you only need to pay once in the 4S shop to repair, the slow leakage process is: the 4S store to give you a car vacuum plus fluorescent Ji and R134 refrigerant, you use it first, when the refrigeration is not very good, you have time to quickly go to the 4S store to review the fast leakage, then solve it on the spot, I hope it will help you.

Theoretically, there will be no shortage of air-conditioned refrigerants forever.

But the air conditioner's piping is linked, so a sealing ring (glued) is needed, but it will always deteriorate one day, so leakage is difficult to avoid.

Add four refrigerants is all the refrigerants of a car, if it is so leaky, the repair shop will already call you to repair the leak, one less bottle is normal, outrageous, you can find him theory. (The question is whether they asked you to repair it last time), it depends on whether there is a leak on the surface of your car, and if you don't find it on the surface, it will be a bit expensive, after all, the car is a high-cost thing.

You can find out if it has been leaked through the following aspects:

1. Look at whether the radiator or copper tube has a cold feeling, if it is not icy, it may be that the refrigerant tube has been damaged, making the refrigerant leak.

2. Adjust the temperature controller, set the temperature 6 to 8 lower than the room temperature, after 15 minutes of operation, the normal air conditioner should have no frost in the hydraulic pipe of the indoor unit, and there is a possibility of leakage freon failure if this phenomenon occurs. There are oil stains on the hydraulic pipe connection of the indoor unit, which also indicates that the air conditioner has leakage freon.

3. If you touch the condensing louver fan behind the air conditioner with your hands, if the temperature does not change, and the compressor is working, it indicates that there is a leakage of freon.

4. The compressor has been working since it was turned on, there is no vibration of shutdown, and the sound of the compressor self-vibration is louder than that of the new air conditioner, which is the abnormal sound caused by the leakage of freon.

5. Find a thermometer, close to the cold air outlet, and see if the thermometer indication is 6 to 8 lower than the room temperature, if the displayed temperature is less than 5 or even the same as the room temperature, and the compressor is still working, it means that the air conditioner Freon may have leaked.

There is also the evaporator that has not been replaced, it may be that the evaporator is leaking, and then it is a leak at the pipe joint, and they will check the leakage point for you when you go to the place where the air conditioner is repaired.

In fact, only the indoor evaporator remains, and the entire countertop may have to be dismantled to check and replace.

Go to the 4S shop to repair it, and you will be responsible for not repairing it.

Add fluorescent agent, you can see it if you leak it, you don't see fluorescent agent if you leak light, then disassemble the workbench.

I still haven't found the leak.

Summary. Hello, the most common reason for leakage of refrigerant in car air conditioner is condenser damage and compressor problems. The condenser is located at the front end of the vehicle, and it is very easy to leak the refrigerant in the event of a collision or impact, and the compressor is also prone to leakage after wear and tear due to long-term operation.

You can suppress it first, reach 15 pipeline pressures, keep it for an hour without leakage, and the whole system will have no problem. If you can't find the leakage, and it will be missing every once in a while, in this case, just replace the compressor, the compressor does not leak in the stationary state, and once it works, there will be leakage. The ** replacement of the brand compressor is 600 yuan, plus the cost of maintenance 800 yuan can be repaired.

Baojun 510 adds two bottles of fluoride a year, and it becomes air the next year.

How to deal with the leakage of the car air conditioner into the car:

1. Replace the drain pipe: the drain pipe is aged, loose or bent and needs to be repaired.

2. Dredging the drainage: the drain is blocked, and the dew cannot be discharged. Clogged pipes can be unblocked.

3. Adjust the body: the indoor unit is tilted excessively, the direction of the pipe joint is too high, and the water flow cannot flow.

4. If the air conditioner is too cold, increase the temperature of the air conditioner appropriately.

Maintenance method of car air conditioner:

1. The temperature of the air conditioner should not be too low: Choosing the right air conditioning temperature is the first step in air conditioning maintenance.

2. Control the direction of the air outlet: the principle of the air outlet of the automobile air conditioner: turn the air outlet up when the air conditioner is turned on, and the air outlet will be down when the heating is turned on.

3. Don't turn on for too long: Using the air conditioner for a long time will cause the condenser pressure to be too large, which will cause loss to the refrigeration system.

4. Properly open the large air volume: the air conditioner will suck in a lot of dust when it is used, and the easiest way is the most effective to blow out the wild Shimin floating dust on the inner surface of the air duct by regularly turning on the strong wind.

5. Turn off the air conditioner when driving at low speed: try to turn off the air conditioner when driving at low speed, and do not make the starting song machine run at a higher speed in order to improve the efficiency of the air conditioner when the traffic is jammed, which will shorten the service life of the engine and the air conditioning compressor.

1.Visual leak detection:

This method is the easiest and most convenient. As long as there is a drowsy or oil stain, that place could be a leak. If there is only a little bit of oil stains, you still can't see it, which is the disadvantage of the visual method.

2.Leak detection of nitrogen and soapy water:

Fill the air refrigeration system with nitrogen to create a certain pressure, and then apply soapy water. If it bubbles, it means it's leaking.

3.Gas differential pressure leak detection:

Using the air pressure difference, you can know whether the refrigerant is leaking by amplifying it through the sensing amplifier.

4.Electronic Leak Detection:

Use a special leak detector to test the quality of the air refrigerant. However, electronic leak detection products are easily damaged and need to be carefully stored.

5.Fluorescent Leak Detection:

The special brightness of a fluorescent lamp is applied to the refrigerant, and the location of the leak can be determined by the different colors of the light. If there is a leak, it will be illuminated with a fluorescent lamp, and the leak will be shown with a yellow light, so that the leak can be accurately located and the problem can be dealt with quickly.

Millions of car purchase subsidies.

1.How to deal with the leakage of the car air conditioner into the car: Replace the drain pipe: The drain pipe is aged, loose or bent and needs to be repaired. If you don't have a search for it, replace it.

2.Dredging the drain: The drain is clogged and the dew cannot be drained. Just unclog the clogged pipes.

3.Adjust the body: the indoor unit is tilted excessively, the direction of the pipe joint is too high, and the water flow is not circulated in the world. It needs to be adjusted in the repair shop.

If the car is closed and regrets the leakage of the air conditioner cooler, then this is because of the aging of your secret file seal, which can prevent leakage as long as the seal ring is replaced, I hope to help the car to you.

When the car is using the air conditioner, check whether the air conditioner's pipes, compressor and expansion valve are abnormal. When there is a problem with the pipes, consider removing and replacing these hoses. If it is due to the compressor problem, the closure tightness of the stroke end of the compressor is insufficient, at the end of the stroke, the refrigerant is highly compressed, and there may be ultra-high pressure.

If there is a problem with the expansion valve, the expansion valve or a similar function, then the refrigerant state changes here, and it is easy to have problems. The probability of this happening is not high, and it should not be too troublesome to change it if it happens. However, it is also possible that the seepage is in the surface cooler, and there may also be trachoma, cracks and the like in the finger band.

Automobile air conditioning refrigerant leakage is very troublesome, and it is necessary to check the leakage point in the **. When inspecting, it is more troublesome than the sail cover air, and it is necessary to disassemble the air conditioning pipes and find the test leakage point piece by piece, so it needs to be repaired and repaired by professionals.

If there is a leak in the refrigerant fluid of the automobile air conditioner, it may affect the effect of the air conditioner refrigeration, so you should go to the repair shop for testing and maintenance as soon as possible.

What else can I do? Find the cause of the leak, fix it, and refill the "refrigerant"!

If the refrigerant leaks in the car air conditioner, you'd better go to the auto repair shop for repairs!
