Have a pungent smell after cleaning your car s air conditioner evaporator?

After using for a period of time or driving a certain mileage, the automobile air conditioning system is in the state of internal circulation or external circulation, and a large number of dust and impurities are adsorbed on the surface of the automobile evaporation box, among which the position of the evaporation box is dark and damp, and it is most likely to accumulate dust and scale.

First of all, the reasons for the peculiar smell after the air conditioner is turned on are:

1. After the air conditioner is used all year round, the indoor filter and copper sheet will squeeze a certain amount of dust, so that after accumulating to a certain amount, a certain odor will be generated, and the air conditioner will be blown into the air with the air conditioner turned on.

2. Because the air conditioner is refrigerated and heated, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without dry and mildew prevention function will be shut down immediately, so that the internal moisture has always existed, and mold will be produced in the long run, and the musty smell will naturally occur.

Knowing the reason, then how do we get rid of odors?

1. If the service life of the air conditioner is not very long, and there is dust in the panel and air outlet, the user only needs to wipe it by himself, and open the panel to remove the filter screen for clean water flushing, which can simply solve the problem of peculiar smell.

2. If the air conditioner is used for a long time and the user cannot simply clean it by himself, we need to contact the after-sales service to clean the air conditioner in time to make the air conditioner more healthy and fresh.

The smell of the car air conditioner after cleaning is because simply cleaning the air duct and blower can not remove the musty odor, to remove the musty odor, it is necessary to clean a key part, that is, the air conditioning evaporation box. The evaporation tank is located in the instrument panel of the vehicle, it is very troublesome to disassemble once, and it can also be simply cleaned, but if simple cleaning cannot be solved, it must be disassembled and cleaned, and this will have to go to a professional repair shop.

I believe that many car owners and friends will have the same trouble: after turning on the air conditioner in summer, there is always a pungent smell (often said: stinky rag smell, earthy smell) from the air outlet, which is particularly disgusting.

When we find out about this, what we often do is to clean the air conditioning system.

to get rid of the odor, but after cleaning, it may only take a while for a while to have a bad smell again.

Description of the symptoms. When I turned on the air conditioner to refrigerate, I could clearly feel that there was an obvious peculiar smell in the cold air coming out of the tuyere, and after discovering this situation, I went to clean the air conditioning pipeline, and the smell was indeed gone in a short time, but it didn't take long for this peculiar smell to come again.

Pathologic analysis. Since the air conditioning lines have been cleaned and the air conditioner filter has been replaced with a new one, it is judged that there is mold or dirt in the evaporation tank, an important part of the air conditioning system, resulting in a peculiar smell of the air conditioner.

Solution. It is necessary to disassemble and clean the inner wall of the evaporation tank and the evaporator inside the evaporation box.

Tips: What is an evaporation tank.

The part that cools the air in the vehicle air conditioning system, which is composed of two parts, the evaporation box housing and the evaporator. Filled with refrigerant.

The evaporator is located in the casing and reduces the air temperature by absorbing a large amount of heat from the surrounding area.

Personally, I thinkIn this case, you may want to consider replacing the cabin air filter. Because the air conditioner filter is dirty, it will produce a more unpleasant odor.

Usually when we are driving a car, if we feel that the temperature in the car is relatively high, we usually choose to cool down by turning on the car air conditioner. As a result, you will be able to have a more comfortable driving experience while driving a car. So the presence of car air conditioning is very important.

The cabin air filter needs to be replaced.

First of all, it is a relatively common phenomenon that the car air conditioner has a peculiar smell, because most cars will produce some different degrees of peculiar smell in the process of turning on the air conditioner after driving for a period of time. Mainly in this case, there is still a peculiar smell after the air duct and evaporation tank are cleaned, so you need to consider replacing the air conditioner filter. This is because if the air conditioner filter is dirty, it will emit odors.

There is a foreign object inside the car air conditioner.

Secondly, after ruling out the above possibilities, if there is still a peculiar smell in the process of hitting the car air conditioner. It is necessary to inspect the car air conditioner, because through the way of inspection, you can check whether there are foreign objects in the car air conditioner. This is because if a foreign substance enters the air conditioner of the car, it is likely to cause odor due to long-term storage.

One of the most common is that rats enter the car air conditioner, and the rats will emit a relatively unpleasant odor when they die in the car air conditioner. <>

Regular maintenance of the car air conditioner is required.

Finally, I personally think that if you want to avoid the smell of your car air conditioner, you need to maintain your car air conditioner regularly. Because through regular maintenance, you can let professional masters carry out relevant maintenance work on their own car air conditioners. And in the process of maintenance, the quality problems of the car air conditioner can be found at the first time, so that targeted solutions can be made according to these quality problems.

And to avoid the possibility of peculiar smell from the car air conditioner from the root.

Many drivers may smell a peculiar smell when they turn on the air conditioner of the car, especially when the weather is hot, this smell will be more serious. So the car air conditioner has a peculiar smell, the air duct has been cleaned, and the evaporation box has also been cleaned, why is there still it? You'll know after reading it.

The smell of the car air conditioner may be caused by the accumulation of dust on the filter

Sometimes, after cleaning the air duct and evaporation box, you can still smell a peculiar smell emitted by the air conditioner, which may be because of the accumulation of a lot of dust in the air conditioner filter, you can try to replace the air conditioner filter to alleviate this kind of problem.

When the weather is hot, many people will turn on the car air conditioner refrigeration, in this case, the interior of the indoor unit may produce a large amount of moisture, so when the driver turns off the car air conditioner again, those air conditioners without automatic anti-mildew and drying functions will stop running in the shortest possible time, so that the moisture inside the air conditioner can not be completely removed, can only stay inside the air conditioner, and a large number of molds may be derived in the long run. After a long time, after turning on the air conditioner again, you can smell a relatively pungent musty smell. The solution to this situation is very simple, in fact, you only need to turn off the air conditioner 5-10 minutes before arriving at the destination, and then adjust to the state of natural wind, and wait until the water vapor in the air conditioner is released.

Precautions when using a car air conditioner

When you warm up the car in the morning, try not to turn on the air conditioner to heat, you should wait for 3-5 minutes, until the temperature inside the engine water tank has increased significantly, and then turn on the air conditioner. The temperature of the air conditioner should not be set too high, especially when running at high speeds, it should be kept in a state of cold air or natural wind, because if you are in a warm environment for a long time, the driver may be sleepy. In addition, you should also pay attention to the fact that you should not use the air conditioner to blow the warm air directly on your face.

The air conditioner should be turned off before parking the car, so as to effectively prevent the growth of mold inside the air duct of the air conditioner.

That's because there are foreign objects at the air outlet of the car air conditioner, so the owner still has a peculiar smell after cleaning the air duct and evaporation box, and it is recommended that the owner comprehensively clean the air conditioning system to solve this fault phenomenon.

Because the smell of the car air conditioner mainly comes from the air conditioner filter, you didn't clean the air filter, so there is still a smell.

It may be due to the aging of some wires in your car, or it may be the aging of some leather seats, which is why there is such a peculiar smell.

The main reason for the peculiar smell of the air conditioner is that the air conditioner has three major conditions for mold growth (i.e., warmth, humidity and nutrient source), therefore, after these stubborn impurities stay for a long time, the evaporation box of the vehicle will become a place for bacteria and mold to grow, therefore, every time the air conditioner is turned on, these bacteria and mold will enter the cabin with the air conditioning wind, and be inhaled into the human body, causing headache, fever, sudden sore throat, tonsil infection, asthma, flu symptoms, dermatitis and wounds that are difficult to heal and other adverse reactions. In severe cases, it will also make people feel uncomfortable such as dizziness and chest tightness. For example, when the air conditioning system is running, the water vapor in the air forms condensate on the surface of the condensation evaporator of the air conditioner, in which - - part of the water will remain in the evaporator and air conditioning pipeline after the air conditioner is turned off, and these moisture will combine with microorganisms and pollutants in the air to become a breeding ground for mold in the humid, warm and dark air conditioning system. Or because of the nicotine produced by the driver and passengers smoking in the car, and the smell of rubber, plastic and leather in the car, as well as the smoke, dust and exhaust fumes in the outside air enter the car and pollute the air conditioning system.
