What is the smell of the air conditioner in the car in winter

1. In winter, the smell is blown out from the air conditioner of the car, mainly because the air humidity is too high or the intersection of cold and hot air in the air conditioning duct, so that the water molecules in the air condense into water droplets, and then form a damp and dark environment suitable for mold reproduction. When the air conditioner is turned on, the water droplets are attached to the evaporator, and at the same time mixed with some dust impurities, resulting in the inability to exclude, and it is easy to breed a large number of bacteria after a long time, and the surface of the evaporator will become moldy, emitting a smell, and then discharged from the air conditioner outlet.

2. You need to clean the evaporation box regularly, first remove the plastic cover plate under the co-pilot's armrest box, wipe it with a rag dipped in water, and wipe off the dust stains.

3. For slight odors, you can park the vehicle under the sun, adjust the knob to the warm air gear, and then turn the fan to the highest gear, open all the doors to discharge the dirty air outside.

4. The air conditioner filter plays the role of the first layer of protection. If it is used for too long, a lot of dust, germs, mold, etc. will be attached to the filter element, which will not only affect the air quality, but also be extremely harmful to the human body. It is recommended to replace it every six months.

With the development of science and technology, air conditioning has been installed in the current production of cars, which can allow us to enjoy a warm or cool travel experience when traveling. However, many people will find a problem, that is, if their car has been driven for a long time, the air conditioner in the car will have a peculiar smell, which is very unpleasant, and even seriously affects their mood when sitting in the car. So why does the car smell in the air conditioner after driving for a long time?

Here's what I think:

First, because the filter element in the air conditioner has not been cleaned for a long time.

The air conditioner in the car is similar to the indoor air conditioner we usually use, and it also has an air conditioning filter. If the air conditioning filter in the car has not been cleaned for a long time, and the air is humid, making the air conditioning filter warm and humid, it is very easy to breed bacteria and mildew. In this case, it will produce a bad smell that will seriously affect our travel experience.

Second, caused by dust and moisture from the outside world.

When the outside air passes through the ventilation duct of the air conditioner, the dust and moisture in the air will inevitably flow into the air conditioning system duct. At this time, there will be some moisture and dust left in the ducts of the air conditioning system, and if these moisture and dust are not cleaned for a long time, they will inevitably produce mildew and unpleasant odors.

3. Regular cleaning of air conditioners is very important.

In order to keep the air in our car fresh, free of unpleasant smells, and make our car experience more comfortable, it is very important to clean the air conditioner in our car regularly. Only when the bacteria and dust in the air conditioner are cleaned will the air in our car be completely renewed.

Because the car has been driven for a long time, the air conditioner filter will accumulate a lot of dirt, so there will be a peculiar smell in the air conditioner.

Because the air conditioner has been on for a long time, a lot of dust has accumulated inside, breeding a lot of bacteria, causing odors inside the air conditioner.

Because there is mold growth on the air conditioner, and if the air conditioner filter is not changed for a long time, there will be a peculiar smell.

Because this will cause the air conditioner to accumulate dust and carbon, and there will be some unpleasant smells during driving.

Reason: The air-conditioning system has always been wet, in the air-conditioning duct, the intersection of cold and hot air makes the water molecules in the air auspicious air condense into water droplets, and the humid environment is the most likely to breed bacteria and mold.

Solution: Before stopping and turning off the engine, the air conditioning compressor should be turned off in advance, and the Danyan beam mode should be adjusted to external circulation. Let the hot air dry the moisture in the cold air channel of the air conditioner, so that the air conditioner will never get damp and breed bacteria, and produce odors.

The reasons for the peculiar smell of automobile air conditioners are: 1. The air conditioning filter has not been cleaned for a long time: the air conditioning filter has not been cleaned for a long time, and the air is humid in the rainy season, which causes the air conditioning filter to be humid and warm, resulting in mold breeding and musty smell; 2. The pipes of the air conditioning system have not been cleaned for a long time

The outside air flows through the ducts of the air conditioning system, which will combine a small amount of residual moisture with the dust in the air, and if it is not cleaned for a long time, it will also produce mildew and produce a sour and rotten odor. The following is the solution to the odor of the car air conditioner: 1. Clean frequently:

Clean the air-conditioning system or replace the air cleaner frequently to reduce the growth of mould; 2. Master the correct method of turning on and off the air conditioner: generally it is best to turn off the air conditioner 5 minutes before parking, and then turn on the natural wind, so that the temperature in the car can be picked up as soon as possible, and the water droplets condensed will not be condensed in the air conditioning pipe due to the temperature difference after parking, so that the air conditioning pipe can be dried and the breeding of mold and fungus can be blocked; 3. Use natural air fresheners: you can put some pineapple, lemon, apple and other fruits in the car to achieve the effect of removing odors; 4. Always use the auto key of the air conditioner panel:

The temperature in the car is relatively stable, the human body will feel comfortable, and the air quality in the car can be maintained.

I believe that many car owners will have trouble with the car. When the air switch is turned on, it will not only bring cool and empty air, but also bring unpleasant smells when it is closed. So what causes the null switch to smell?

1.It may be that the residual moisture in the air conditioning system ducts combines with the dust in the air conditioner system, which in turn produces mold and causes odors. The surface of the evaporator is moist and warm, and mold can grow if it is not cleaned for a long time. When

2.Another reason is that your air filter is too dirty.

At present, the vehicle air filter element contains environmentally friendly activated carbon. Activated carbon media is specially designed to treat air odors and pollutants in the air, and is also widely used for air air filtration in air ventilation places. Activated carbon media contains 100% surface adsorption capacity, which can effectively remove a large number of odors and harmful gases.

If there are more impurities or pollen attached to it, it will also produce an odor, but the sour taste is generally stronger. Replacing the air filter in time when you notice odors is very important for healthy driving.

3.If you smoke in the car when using the internal circulation mode of air conditioning, it is easy to leave smoke and tar in the distribution box of air conditioning, and it will cause odor in the air conditioning system for a long time.

In short, the peculiar smell of the air conditioning system is caused by many reasons, not the quality of the product itself. Although odor control is not a fatal problem, it is not to be underestimated. Therefore, in view of the above problems, it is recommended that the empty distribution box should be dried with natural wind or warm air in time after sunny days to prevent the air distribution system from becoming moldy due to the large degree of wetness in rainy days, and the air conditioner should be turned off before stopping, and then the natural wind should be turned on to keep the empty distribution box relatively dry, and the pollen filter and [k0] power distribution system should be replaced regularly.
