It s a hot summer day, and the air conditioner in the car has a strange musty smell, maybe it has so

Yes, there must be a relationship. The solution to the musty smell of the car air conditioner is: 1. Drive the car to the sun, turn the air conditioning system to the warm air shield, adjust the air volume to a larger place, and dry the car for about 10 minutes in the state of the door and window are fully open; 2. Place bamboo charcoal products in the car to absorb musty smell and reduce taste; 3. Replace the air conditioner filter; 4. Use cleaning agent to clean the air duct of the air conditioner; 5. Clean the evaporation box; 6. Turn off the air conditioner before stopping, and let the natural wind dry the water condensed upward in the wind to avoid mold.

It is not possible to do it for a long time without cleaning the air conditioning system, and it is easy to accumulate dirt and harmful substances in parts such as evaporation tanks, and the air in the car will be affected and become unhealthy. In addition to changing the air conditioning filter, it is recommended to thoroughly clean the air conditioning system, including pipes and evaporation tanks. The air conditioning system in-depth care kit, TA contains three products, namely air conditioning decontamination and cleaning agent, air conditioning sterilization and deodorizer, and air conditioning bacteriostatic agent, with visual equipment operation, fast and efficient, safe and convenient, which can thoroughly clean the dirt inside the air conditioning pipe and evaporation tank, and solve the problem of air conditioning odor from the root.

I don't understand myself yet.

Yes, it's hot and humid in the summer, and most of the cars are closed doors, so it's inevitable that there will be a smell. Moreover, it is necessary to pay attention to the maintenance of the environment in the car and replace the air filter in time.

Replace the air conditioner filter and clean the air conditioner ducts.

1. Replace the cabin air filter.

The air conditioning filter element is a place that is easy to be ignored, many car owners don't even know that there is an air conditioning filter element on the car, the dirty filter element not only does not play the original role, but also causes secondary pollution to the air entering the car, and the source must be blocked if you want to completely remove the odor in the car. Under normal circumstances, the service life of an original air conditioning filter is one year or 30,000 kilometers, if the vehicle is often driving on roads with poor air quality, it is necessary to shorten the replacement cycle of the filter element in time.

2. Use the fan to run at a high level.

For slight odors, park your vehicle in the sun, adjust the knob to the warm air setting, then turn the fan on the highest gear and open all the doors to allow dirty air to escape outside. This can not only use ultraviolet rays to disinfect the interior of the car, but also effectively clean up the dust in the air duct, and effectively remove the odor of the car air conditioner after about 5 minutes of operation.

3. Clean the air duct of the air conditioner.

Changing the filter cartridge regularly can keep dirty air out of the car, but in vehicles that have been used for a long time, there will still be dust and mold in the air conditioning system, so it is necessary to use an air conditioning duct cleaner to clean it. At present, there are many brands of air conditioning cleaning agents on the market, ranging from tens of yuan to hundreds of yuan, and car owners can clean up after purchasing. First, find the installation location of the air conditioner filter, spray the cleaning agent from the filter position into the air duct, then turn on the air conditioner to the highest setting, open the window and run for a few minutes.

The air conditioner also needs a compressor and refrigerant, so it is necessary to check the capacity of the refrigerant in advance, and if it is less, it needs to be added in time. Appropriate air volume; (The above direction of the position of the air outlet is adjusted according to the demand) The blowing window is used in winter, just adjust the position of the air outlet to the trapezoidal wind window sign. Rear windshield defrost The square window heating button at the center console opens to heat the rear windshield.

When the hot air blows up, the water vapor in the air inside the car solidifies, causing fogging. In fact, at this time, turn on the outer circulation (which is another button to return the arrow), and then blow the wind direction to the windshield and turn on the AC switch, and the fog will disappear immediately, so there is no need to change the temperature of the air conditioner. Its function is similar to that of the human lungs, which is to filter out impurities and particles in the air.

Because impurities, dust and other substances are always filtered, the air conditioner filter will become very dirty in long-term use. This requires frequent cleaning by the owner.

At the same time, don't adjust the temperature too low, the temperature is too low, but it will make people feel uncomfortable and will affect their health. Generally, the temperature difference between the inside and outside of the car is within 10 degrees; If the temperature difference is too large, fog frost will appear on the glass, affecting the driver's vision. Refrigeration and air conditioning to open the internal circulation can not only ensure the effect but also save fuel and energy, is a good way, but after a long time, the air in the car is not circulated, people will feel uncomfortable, we also need to properly close the internal circulation to introduce a little fresh air.

There is no power supply for the car, even if it is open, there is no problem, but when you start the car next time, the compressor of the vehicle will be turned on directly, which will consume more fuel to a certain extent, and will also consume the durability of the car battery and affect the normal operation of the car. At this time, you need to wait for the water temperature to rise, do not turn on the air conditioner before the water temperature rises, so that the heat will be lost, the water temperature will rise more slowly, and when the water temperature is about to reach normal, turn on the air conditioner, open the internal circulation, so that the temperature will come up quickly.

Yes. It may be that there are a lot of bacteria in it, and timely replacement can still maintain your health.

Yes, if there is such a situation, you must change the filter element in time, and this situation is because the temperature of the air conditioner is too high, so there will be a musty smell.

Of course, you need to change the filter element, and something that is often used like the air conditioner in the car, it is best to choose some good quality when buying.

It should be, it is very likely that there is a problem with the filter element in this air conditioner, so it will lead to the problem.

Car air conditioners have a musty smellThere are two main reasons, dirty air conditioner filtersIt's just one of them, and the other isDirt in the evaporator of the air conditioner。In order to better understand why dirty air filters and evaporators can cause musty odors, let's first explain how the air conditioning system works, and then propose a specific solution.

How car air conditioners workRefrigeration principle:We all know thatThe liquid evaporates into a gas that absorbs the heat of the surrounding air and thus achieves cooling, and this is also the simple principle of automotive air conditioning and refrigeration. After the refrigerant (R-134A) comes out of the evaporator, it becomes a high-pressure gas through the compressor, then becomes a high-pressure liquid after circulating to the condenser, and then becomes a low-pressure liquid through the extrusion of the expansion valve, and finally enters the evaporator to transform into a low-pressure gas by absorbing the heat of the surrounding air, and so on and so on to form a refrigeration cycle.

The cooled air around the evaporator is fed into the car by the blower to achieve the effect of refrigeration.

Heating principle:Automobile air conditioning heating generally adopts water heating, that is, the coolant in the engine cooling system is used as a heat source, introduced into the car for heat exchange, and then the heated air is sent into the car through the blower.

The cause of musty smell in car air conditionersEvaporator dirty:It can be seen from the refrigeration cycle of the automobile air conditioner that the evaporator has been in the environment of alternating cold and hot for a long time, and has been circulating between heat absorption and heat release, and its installation position is deep in the instrument panel. Then the evaporator will inevitably become a "hotbed" for mold breeding in such a dark, humid and cold environment for a long time, and the cold air blown by the blower will also have a musty smell, and the dirty evaporator is also one of the important reasons for the musty smell of the air conditioner.

The air conditioner filter is dirtyIf you do not replace it for a long time, the accumulation of particles will be more and more, coupled with the flow of some humid air such as rainy days, it will gradually make the air conditioning filter lose its filtering effect and gradually mold and produce peculiar smell.

Solutions and prevention methods for musty odor of automobile air conditionersFor evaporator dirt:If the evaporator is not dirty (no musty smell), you can turn off the ac before stopping the refrigeration cycle each time, and then turn on the natural air circulation for 1 2 minutes to blow away the humid air around the evaporator to keep it in a dry external environment, which can effectively prevent the problem of mold in the evaporator. If the evaporator is already dirty, you need to go to a repair shopNo dismantling and cleaning

Of course, for car owners with strong hands-on ability and time and money, they can also buy equipment by themselves, and refer to the manual to simply complete evaporator cleaning, atomization and disinfection of the whole car.

Summary: The musty smell of automobile air conditioner is generally caused by the dirtiness of the evaporator and air conditioning filter, which needs to be cleaned and replaced accordingly to solve it. Here, it is not advisable to cover up the musty smell by putting items such as perfume, because the presence of moldy fungi in the air not only does not decrease, but can harm the health of the family in the long run. Therefore, when the vehicle air conditioner has a musty smell, it should be dealt with at the after-sales maintenance point in time.

Yes, the air conditioner filter should be replaced after a period of time, otherwise it is not good for your health.

Car air conditioners have a musty smell, not because the filter has been used for too long. Rather, it is because I usually do not clean the air conditioner in the car, so there will be a lot of dirt left on it, resulting in a musty smell in the air that blows out.

If the air conditioner of the car has a musty smell, it may be that the filter has been used for a long time, so I suggest that you can go to the 4S store to replace the air conditioning filter.

Indeed it is. This year, there is a lot of rain, especially in the south, after the rainy season, the car is also prone to mold, of course, it will be the fastest time for bacteria to grow. Water vapor will also adhere to the air conditioner evaporator, and there will also be aspergillus, yin mold, and penicillium.

These molds can also cause headaches and fevers in people!

How to deal with the musty smell of car air conditioner?

1.Soak up the sun.

The most cost-effective way is to remove the musty smell from the car and the air conditioner. You can find a sunny day to pull the car down under the sun, let the car air conditioning system in the warm air gear, and then turn on the air volume to the maximum, and bask in the car for more than ten minutes with the doors and windows fully open. In addition, check whether the air filter is clean or replaced.

There are many air conditioning air duct cleaners on the market, and you can also buy your own bottle to rinse it yourself!

2.Use bamboo charcoal.

Bamboo charcoal also has a very large adsorption force, can absorb moisture, chloride and sulfide and other harmful substances, put a few packs in the car is also a good deodorant products. In addition, bamboo charcoal also has a two-way humidity control effect, of course, it can also ensure that the humidity in the car is balanced, and inhibit the production of microorganisms in the car.

At present, it is common to see more activated carbon air purifiers in the market, which also increase the more healthy negative ions in the air, so that the air is fresher and cleaner. Riders can also buy a small bag and put it in the car, in addition to the built-in bamboo charcoal car mat and pillow and foot mat are also **!

3.Car car perfume.

Perfume is also suitable for when the smell is not too serious, sprinkle some perfume in the car or place a bottle of perfume, which can not only reduce some odors, but also be more romantic. However, it is also a reminder that most car owners love lemon-flavored perfumes, most of which are acidic, easy to gather in the air conditioner evaporator, and easy to mold and deteriorate, and will also produce peculiar smells. If you prefer perfumes, it is better to use neutral and milder flavors!

1. Clean the air conditioning system or replace the air filter element frequently to reduce the growth of mold;

2. Master the correct method of turning on and off the air conditioner, it is generally 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 block the breeding of mold and fungus.

3. Use natural "air fresheners", you can put some pineapples, lemons, apples and other fruits in the car, which can achieve the effect of removing odors.

4. Frequently use the auto button of the air conditioning panel to make the temperature in the car relatively stable, the human body will feel comfortable, and the air quality in the car can be maintained at the same time.

A large number of laboratory tests have shown that mold in the air conditioning system mainly includes three types of molds that are harmful to human health: Aspergillus, Yin mold and Penicillium, which can cause the human body such as:

Fever, sudden sore throat, tonsil infection, dermatitis and asthma are other adverse reactions. Therefore, the correct use of car air conditioning to reduce the growth of bacteria is very important for the health of passengers.

1.Open the window first and then turn on the air conditioner In summer, the outside temperature is high and the sun is sufficient, and after the car is exposed to the sun, the interior will emit carcinogenic gases such as benzene and formaldehyde. In this case, if you turn on the air conditioner as soon as you enter the car, you may inhale these toxic gases.

Do: Do not immediately enter the car after sun exposure, or do not enter the car after entering the car.

2.After turning on the air conditioner, some car owners let the wind blow at will, or blow flat to themselves, or even choose the windshield mode, in fact, it is not appropriate to do so, because of the windshield.

3.Switching between internal and external circulation When driving for a long time, it is necessary to make full use of the internal and external circulation function of the air conditioner. There may be new car owners who don't know much about it.
