Car air conditioner leaks slowly, can it be solved with fluorescent agent?

OK. <>

When there is an air leakage problem in the automobile air conditioner, it should be considered from three major aspects: the air conditioning pipeline, compressor and expansion valve to study. Now let's analyze the countermeasures to be taken to deal with air leakage caused by these three reasons.

Coping methods: 1. When there is a problem with the pipeline, you can consider dismantling and replacing these hoses.

First, 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.

Second, if there is a problem with the expansion valve or a component with similar functions due to the expansion valve, then here, the refrigerant state changes, and the problem is prone to occur. 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 in the surface cooler, there may be trachoma, cracks, etc.

In addition to the above methods, to deal with the air leakage of the air conditioner, it is also necessary to strengthen the maintenance of the car air conditioner, so as to greatly reduce the air leakage of the air conditioner. Maintenance method: 1. Be cautious in air conditioning modification:

It is not advisable to modify the car's air conditioner, because the original air conditioner is matched with the car's engine, and if it is modified at will, it will affect the performance of the car.

It is not possible to solve the problem with fluorescent agents, it is best to go to a repair shop.

We study air conditioning ducts, compressors, and expansion valves.

No, you should go to a repair shop and use professional equipment for repair.

No, fluorescent agents do not stop leaks.

No, you need to use professional maintenance equipment.

It is recommended to go to a professional repair shop for repairs.

It can be solved, and fluorescent agents work wonders for this problem.

No, the two have nothing to do with each other.

Fluorescent powder leak detection, you can directly check the leakage, if you don't solve it, you have to add fluoride for a long time.

It is recommended that you should go to a professional repair shop for maintenance.

In the summer, when we drive, we usually habitually turn on the empty switch of the car. Cars But friends, the cars we use in hot weather Fluorescent agent car air conditioning hazards, air conditioning maintenance methods. Let's talk about it briefly for our friends.

The hazards of fluorescent agents to automobile air conditioning.

When the refrigerant is filled into a new car, a fluorescent agent is added to facilitate the inspection of pipeline leaks. The amount of addition is very small, and it is harmless to the air conditioning system.

The new car needs to fill the air conditioning pipeline system with a special fluorescent agent, and then do a good job of refrigerant filling. After 20 minutes of operation, or after the customer has used it for a period of time, wear special glasses and use ultraviolet spotlights for detection. If there is a leak, the corresponding place will show the green shader celery lantern.

Fluorescent agent is beneficial to repair, improve repair efficiency and shorten misjudgment. Practice has shown that it is not harmful to the system as a whole. It doesn't have to do anything with the human body.

Introduction to car air conditioning and maintenance: maintenance methods.

Adjust the cleaning agent to vaporized liquid and shake well before empty use;

When using this product, the tank inclination is less than 70 degrees; Don't turn it upside down.

Keep away from fire and children.

This is a brief introduction by Bian Xiao Automobile to friends about the hazards of fluorescent car air conditioning school and the maintenance method of air conditioning school. I don't know if my friend has learned after watching it. The air conditioning of the car is the same as the air conditioning we use at home.

Basically, we need to clean the dust inside regularly, or blow it off.

Millions of car purchase subsidies.

Usage: 1. Fully ** refrigerant in the air conditioning system.

2. After the air conditioning system is vacuumed and placed for a period of time, confirm that there is a leakage before proceeding to the next steps.

3. Mix a small amount of fluorescent agent (about a few grams) with a small amount of refrigeration oil (if there is a manual pressure pump, it can also be directly injected).

4. Put the fluorine meter charging hose in vacuum state into the refrigeration oil, open the low-pressure hand valve of the fluorine meter, and under the action of atmospheric pressure, the fluorescent agent is pressed into the air conditioning system together with the oil.

5. Add refrigerant according to the normal operation method.

6. Idle the car, turn on the air conditioner, and continue to fill the refrigerant at the same time, to reach the standard 1 3 or 1 2, the air conditioner of the general model can add about 500 grams, so that the air conditioning system runs for at least half an hour.

7. Use ultraviolet lamps to irradiate all parts of the air conditioner.

8. Put on "identification glasses" and carefully observe the connections of various parts of the air-conditioning system, if there is a leak, the fluorescent agent will seep out with the refrigerant, and the yellow-green fluorescence can be observed through the irradiation of the ultraviolet lamp.

9.Fluorescence leak detectors can quickly detect leaks in vehicle air conditioners and other high-pressure systems, without counting and not missing tests. The tracer dye is injected into the air conditioning system, and the dye will circulate with the refrigerant in the air conditioning system, leaving the dye at the leak point when there is a leak or overleak in the air conditioning system.

The dye at the leak glows under the irradiation of the UV lamp, making it easy for maintenance personnel to find the leak.
