I have a 10 year old Audi A6L 2 0 and the air conditioner is not cool, what could be the reason? Sol

The air conditioner is not refrigerated for the following reasons:

1. Lack of refrigerant. The quality and purity of fluorine are not up to standard, which will directly affect the refrigeration effect of air conditioning;

2. The compressor not working is also a reason. Now the compressor of the air conditioning system is equipped with a clutch, and the compressor only works when the clutch is engaged. If the compressor is damaged and cannot be switched to the pick-up state, then it is natural that the air conditioner does not refrigerate.

If the problem of the air conditioner not being cooled at all can not be solved after pumping the refrigerant and testing the tightness of the air conditioning system, then replacing the compressor is the main work to be done in the next step. Replacing the compressor requires the refrigerant of the air conditioning system to be evacuated and then replaced. After replacing the compressor, it is also necessary to check the tightness of the air conditioning system and fill it with refrigerant.

3.If the solenoid valve coil in the compressor is broken, it will also cause the car air conditioner to not be cool, in this case, only replace the solenoid valve coil, not the whole thing.

How to deal with it needs to determine the cause first, and it is recommended to do a car condition check first. There is a special test, search for "my car" to see.

There are four most common reasons why a car air conditioner is not cool:

1. The quality and purity of fluorine. The quality and purity of fluorine plays a crucial role in car air conditioners, and often poor quality fluorine can lead to inefficient air conditioning.

2. Condenser and water tank. The heat dissipation of the condenser and water tank will also affect the use of the air conditioner, and if it is not cleaned for a long time, the condenser and water tank will be covered with foreign body dust.

3. The use of fluorine. Many car owners think that the more fluorine in the air conditioner, the better, but this is not the case. In the process of fluoridation, the amount of fluorine is neither too much nor less.

If there is less, the pressure in the air conditioning pipe will not be enough, and if there is more, the pressure will be too high. In the above two cases, the air conditioner does not run and refrigerates constantly.

Fourth, the quality of the expansion valve. The expansion valve is an important component in the refrigeration system and is generally installed between the reservoir and the evaporator. Inferior expansion valves can make the refrigerant not work as well as it should.

1. Too little refrigerant causes insufficient refrigerant. If the refrigerant in the air conditioning system is insufficient, the refrigerant injected into the evaporator from the expansion valve will be reduced accordingly, resulting in the refrigerant evaporating in the evaporator, the heat absorbed will also decrease, and the refrigeration capacity will also decrease.

2. Once there is air in the air conditioning system, it will cause the pressure of the refrigeration pipe to be too high, or the refrigerant circulation is poor, which will also cause insufficient refrigeration, mainly due to the poor sealing of the refrigeration system, or the vacuum is not completely evacuated in maintenance.

3. Too much refrigerant causes insufficient refrigeration, too much refrigerant in the empty car, generally occurs during maintenance, caused by excessive refrigerant, the proportion of refrigerant in the air conditioning system has certain requirements, if the proportion is too much, it will affect its heat dissipation, that is, the heat dissipation is large;

4. On the contrary, if the heat dissipation is less, the cooling capacity will be small. Compressor problem, the compressor of the air conditioning system has a clutch, and the compressor only works when the clutch is engaged. If the compressor is damaged and cannot be switched to the pick-up state, the air conditioner will not refrigerate.

If the refrigerant is sufficient and the air conditioner is still not cooling at all, it may be that the compressor has stopped working, and it is necessary to consider repairing or replacing the compressor.

Solution: When the vehicle is not refrigerated, it is necessary to check whether the air conditioning pump can start and operate normally, and check whether the refrigeration dose is normal, if the air conditioning pump can not be started, it should be that there is a problem with the relevant control circuit or there is no refrigerant in the system, resulting in the air conditioning pump in a protective state.

The working pressure of the high-pressure and low-pressure pipelines can be observed by connecting the pressure gauge to judge, and the refrigeration dose can also be intuitively checked through the observation window on the high-pressure pipeline.

If there is a leak in the refrigeration cycle, and the refrigerant is not replenished regularly, the leak can be detected by a leak detector and repaired to replenish the refrigerant. If the expansion valve or low-pressure pipeline is blocked, the liquid storage tank or high-pressure pipeline is blocked, and the pressure bubble of the expansion valve is leaking and the relevant parts can be removed or replaced, and if the pressure bubble is leaking, the expansion valve can be replaced.

Attention needs to be paid to the use of car air conditioners.

In winter, the air conditioner should be started regularly, and the winter in some areas is relatively warm, such as Guangdong and Hainan, and some car owners do not use air conditioning throughout the winter.

If the air conditioner is not used for a long time, the rubber ring will deteriorate, and the lubricating oil on the internal parts of the air conditioner will also dry out.

1. The zero live wire of the air conditioner power supply is reversed.

2. The fan or capacitor of the internal or external unit is damaged.

3. Refrigerant leakage or refrigerant quality is not up to standard.

4. The compressor capacitor is damaged or defective.

Hello! It is recommended that you check the fuse first, and then see if there is cold coal, and check the compressor.

Hello, it may be that the compressor is not working.

Summary. This fault is caused by poor heat dissipation of the condenser, blockage of the air conditioning line, excessive pressure, and compressor protection. To repair this fault, you can first clean the dirt behind the condenser and the air conditioning filter, and then check the air conditioning line pressure, evaporation tank temperature, engine load, water temperature signal, etc.

Find out which sensor signal is off, replace the sensor and check the wiring. There is no problem with all of the above, considering that the fault is caused by the pipeline being too dirty or caused by ice blockage, in this case, after the refrigerant is released, the pipeline is thoroughly cleaned, the drying bottle is replaced, and the refrigerant can be refilled. When summer comes, the condenser is cleaned with compressed air before using the air conditioner, which can ensure that the pressure in the air conditioning line is not too high, and can also effectively reduce the wear and tear of the compressor and reduce fuel consumption.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

1. If the air conditioner has no wind or the amount of wind is small, it is necessary to check whether the air conditioning filter is dirty, whether the blower can operate normally, and whether the air conditioning copy motor can be converted normally.

2. The freon of the air conditioning system is missing, and it is necessary to check whether the system is leaking, and after the maintenance is confirmed, add the freon to the standard range.

3. The condenser of the water tank is dirty, and the engine cooling system is faulty, resulting in too high water temperature, such as the cooling fan does not work, etc., resulting in poor heat dissipation of the water tank and the condenser.

4. The data of each sensor such as the air conditioning pressure sensor and the evaporation box transmission sensor are incorrect, resulting in the inability to adjust the air conditioning system correctly.

5. The adjustment solenoid valve of the air-conditioning compressor is damaged, the clutch of the air-conditioning compressor is damaged, and the internal of the air-conditioning compressor is damaged.

6. Caused by the failure of the air conditioning system line or control unit. When the car air conditioner is not refrigerated, you can choose a relatively professional maintenance organization for inspection and maintenance. For example, the 4S shop or brand repair shop of the model brand shall choose the maintenance organization according to its own actual situation.

If there is a leak in the refrigeration cycle, and the refrigerant is not cooling because it is not replenished regularly, the leak can be detected with a leak detector and repaired to replenish the refrigerant. If the expansion valve or low-pressure pipeline is blocked, the liquid storage tank or high-pressure pipeline is blocked, and the pressure bubble of the expansion valve is leaking, resulting in no refrigeration, the relevant parts can be disassembled or replaced; If pressure bubbles leak, replace the expansion valve.

The grinding voltage of the automobile air regulated power supply is not enough, resulting in no cooling. The solution is to maintain a normal supply voltage. The empty power is not enough, resulting in no cooling.

The solution is to match the power of the empty with the required cooling capacity. Adjustment of no cleaning and no maintenance for a long time leads to no refrigeration. The solution is to clean and maintain the air adjustment.

There are many reasons why the air regulator of the car does not cool, such as the aging of the air regulator compressor, the decrease in capacitor capacity, and the failure of the pipeline. A clogged automotive air regulator filter can also cause the air regulator not to cool. Under normal circumstances, the air conditioning and refrigeration air needs to be filtered by a filter element before it can reach the car.

If the [k0] filter is clogged, a portion of the cold air will be clogged. When cold air accumulates near the temperature sensor, the wrong car temperature will be fed.
