What should I do if the air conditioner in the car smells, and what should I do if the air condition

1. 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.

2. Replace the cabin air filter.

The air conditioning filter is the easiest place to be overlooked, many car owners don't even know that there is an air conditioning filter on the car, the dirty filter not only does not play the original role, but also causes secondary pollution to the air entering the car, if you want to completely remove the odor in the car, you must block the source. 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.

3. Clean the air duct of the air conditioner.

Replacing the cabin air filter can effectively prevent some dirt and bacteria from entering the car, but if bacteria remain in the air duct, it can also cause odors. Use an air duct cleaner for air conditioners to remove odors in the air ducts. Car owners can purchase air conditioning duct cleaners on demand.

The cleaning method is also very simple, after parking the car in a place with a good air environment, turn on the external circulation switch to turn the air conditioner to the natural ventilation gear, and then aim the cleaning agent at the air supply outlet and spray it evenly into the air duct, after a few minutes, open the window and open the air conditioner to ventilate thoroughly. Of course, this method is also suitable for air ducts that are not very polluted, if it is those vehicles that have not been cleaned for a long time, it is best to go to a professional car maintenance center to do a thorough steam sterilization or photocatalyst for the car is more effective.

4. Clean the evaporator.

The air conditioner evaporator is an important part of the refrigerant evaporation and air refrigeration, and the water vapor in the air will condense on the evaporator, so that the evaporator will be in a humid state for a long time, which is easy to breed mold and produce peculiar smell. Therefore, the evaporator should be cleaned regularly. If the evaporator is slightly polluted, the air supply duct of the air conditioner can be removed and purged with compressed air; If the evaporator is seriously polluted, the evaporator should be disassembled, cleaned with water, and the refrigerant should be refrigerant and filled.

In addition, turn on the cold air at least once a month in winter for 3 5 minutes each time, which is conducive to keeping the evaporator dry and reducing mold growth.

After the rain in the valley, summer is not far from us. We're going to get steamer weather all over the country. But for car enthusiasts, it's the season of frequent use of air conditioning.

However, many people do have a headache for the odor problem in the air conditioner. Some people say that just put a bottle of perfume will do, but the symptoms will not cure the root cause. So how do we deal with the odor in the car effectively and thoroughly?

Hello <>: the evaporation box is dirty and must be cleaned, if it is dirty, the heat exchange can not go out, the whole outside has become a big ice mound, turn off the air conditioner for a while the ice lump melts and it is good, waste of oil and the refrigeration effect is not good, it must be cleaned.

In the refrigeration process, the refrigerant produces some moisture, and mildew occurs after a long time; Spray with foam cleaning agent, rinse it clean after finishing, and disinfect and disinfect after cleaning, so that the system is relatively complete after cleaning.

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 a certain amount, a certain odor will be generated, and with the air conditioner turned on, the air conditioner outlet odor will drift into the air. Since 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 will always exist, and mold will be produced in the long run, and the musty smell will naturally occur.

2.Some non-high-efficiency filter systems at the end of the air supply, such as computer rooms, hotel rooms, etc., although the interior decoration is good, and the fresh air and air supply of the air conditioner are filtered, dust can still be found near some indoor air supply outlets and on the surface of the window sill, and dust will also adhere to the inside of the air conditioner.

3.After the control system is started, the concentration and odor of bacteria in the room increase, which is due to the slow evaporation of the condensate retained on the heat exchange coil, ribs and their surrounding parts to form a high humidity (and high temperature) condition around the coil, and become a suitable environment for microbial reproduction, and a large amount of gas generated during reproduction is suddenly released due to the system drive, becoming the source of foul odor.

1.To clean the condenser and fan of the external unit, there is no need to dismantle the shell, rinse it with tap water, and be careful not to get the water on the electrical parts.

2.Clean the inner filter, open the movable shell and remove it, and rinse it with tap water.

3.Clean the evaporator of the internal machine, open the movable shell and remove the filter screen to see the evaporator with metal fins, prepare a bottle of special air conditioning cleaner (generally sold in large supermarkets), spray the detergent evenly into the evaporator in the state of power failure, and start the air conditioner after waiting for 15 minutes, and the dirty things will flow away with the condensate.

Automobile air conditioning device is referred to as automobile air conditioner. It is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide a comfortable riding environment for the occupants, and reduce the fatigue of the journey.

Clean the air conditioner filter directly.

After purchasing a special air conditioner foam cleaner, take out the air conditioner filter of the air inlet of the car air conditioner, open the doors and windows, adjust the air conditioner to the highest setting, spray the cleaning agent into the air intake, and close the air outlet of the air conditioner at the same time to avoid the cleaning agent flowing out during operation. Start the car and let the cleaning agent circulate in the air conditioning system to ensure that the cleaning agent circulates to all channels of the air conditioning system, effectively cleaning the system, killing bacteria and refreshing the output air. After cleaning, the dirt in the air conditioning system will flow out of the air conditioning duct system located in the chassis with the cleaning agent, so it is recommended to replace the air conditioning filter with a new one or clean the original filter element and install it back in place.

The smell of the air conditioner in the car may be caused by mold in the air conditioner evaporator and bacteria accumulating and multiplying on it, and the air conditioner filter element may also cause the air conditioner to have a peculiar smell if it is not replaced for a long time. If the air conditioner is just turned on in the car and there is a peculiar smell, it is recommended to replace the air conditioner filter with a new one, or clean the original filter and then install it back in place.

The most likely odor in the common air conditioning structure is the evaporation box (evaporator), and the evaporation box is an important part of air conditioning and refrigeration. The "refrigerant" passes through the evaporation box, and the evaporation box absorbs heat through heat exchange with the outside air to achieve the refrigeration effect. A small amount of moisture and dust may adhere to the evaporation chamber, which will cause mildew and odor over time.

The air conditioner filter is mainly to filter the air, and the air will reach the evaporator only after the air conditioning filter, so the air conditioner filter plays the first layer of protection. In addition to filtering dust, the air conditioner filter will also absorb odors, and not changing the air conditioner filter for a long time will also produce odors.

The air conditioning air duct is the ventilation duct, and the air conditioning air duct is easy to accumulate dust, but it is often overlooked. The odor of the air conditioner also has a lot to do with the use environment, for example, if the air quality is not very good, the external circulation is opened, and the air conditioner's own filtration system is not efficient.

1) The solution to the odor of the air conditioning exhaust duct.

The best way is to choose an open, sunny environment, open the door, turn on the external circulation to the maximum (do not turn on the air conditioner), or turn on the warm air for 5-6 minutes to blow the smell out.

2) The solution to the odor of the air conditioner filter.

The air conditioner filter is generally replaced once a year, but it is feasible to change the air conditioner once every three months when the air conditioner is often used or the external environment is extremely poor. If the air conditioner filter is dirty, you can simply blow it, but you should avoid cleaning it many times, otherwise the filtration effect of the air conditioner filter will be significantly reduced.

3) The solution to the odor on the evaporation box.

This kind of odor is more difficult to deal with, usually it is recommended that you go to a professional maintenance company to do air conditioning cleaning, cleaning is when the air conditioner is turned on, spray special air conditioning cleaning agent to the blower.

The air conditioner in the car should be removed and cleaned regularly to remove formaldehyde;

Formaldehyde in new cars is mainly used in seats, seat cushions, floor cushions, interiors, paints, adhesives and other materials. Choose photophyll materials to decompose formaldehyde in the car, and the first two years of use of the new car are the time when formaldehyde volatilizes the most. Pay attention to the aldehyde removal method of the new car.

First, the packaging plastic in the car should be removed as soon as possible, so that the harmful gases can be released quickly.

2. Open windows for ventilation.

Every time you open the window for ventilation before the car starts, and then leave, or usually stop the car window to flow out of a small crack, keep the car ventilated, can effectively reduce the concentration and odor of harmful gases in the car.

3. Place activated carbon.

There are car-only ones. Balonidite can play a key role in the adsorption and decomposition of formaldehyde.

Four: Place the peel of the fruit.

When the odor in the car is very strong, in order to remove the odor in the car as soon as possible, you can put some fruit peels or fruits in the car, so that the fragrance of the fruit can cover up other unpleasant odors in the car, but this method has no effect on removing formaldehyde.

There are odor treatment methods for the air conditioner in the car, such as running the fan at high speed, replacing the air conditioner filter, cleaning the air duct of the air conditioner, etc.

1. Use a fan to run at high speed.

For slight odors, you can park your vehicle in the sun, turn the knob to the warm air position, then turn the fan to the highest, open all the doors to exhaust the dirty air outside. This not only disinfects the car with ultraviolet light, but also effectively cleans the dust in the air duct. After running for about 5 minutes, it will effectively remove the odor of the car air conditioner.

2. Replace the air conditioner filter.

Aircon filters are the most overlooked place. Many car owners don't even know that there is an air conditioning filter in the car. An unclean filter element not only cannot play its original grand tremor function, but also causes secondary pollution to the air entering the car.

In order to completely remove odors from the car, it is necessary to block the source. Generally speaking, the service life of the original air conditioner filter is one year or 30,000 kilometers. If the vehicle is often driven on roads with poor air quality, it is necessary to shorten the filter replacement cycle in time.

3. Clean the air duct of the air conditioner.

Changing the filter cartridge regularly can keep dirty air out of the car, but after a long period of use, the air conditioning system will still have dust and mold. At this time, it is necessary to use an air conditioner duct cleaner for cleaning. Owners can clean it themselves after purchase.

Find the installation location of the air conditioner filter, spray the cleaning agent from the filter position into the air duct, then turn the air conditioner to the highest setting, open the window and run for a few minutes.

Common sense of daily maintenance of car air conditioner:

1. Outdoor parking in summer, the sun is quite fierce, and the parking time is long under the scorching sun, so do not use the air conditioner immediately after the vehicle starts. First open all the windows, start the external circulation, exhaust the hot air, and wait for the temperature in the cabin to drop, then close the windows and turn on the air conditioning.

2. In order to save fuel, some car owners turn off the air conditioner when they get out of the car and go to the toilet. Therefore, the air conditioner will be turned on and off frequently, which is not right, because it is easy to damage the air conditioning system.

3. For daily driving, it is best to turn off the air conditioner a few minutes before parking, turn on the natural wind later, and make the temperature in the air conditioning pipe rise before parking, so as to eliminate the temperature difference between the cherry blossoms and the outside world, so as to keep the air conditioning system relatively dry. Avoid the growth of a large number of molds due to moisture.

4. During the use of the automobile air-conditioning system, the surface of the small water tank of the blower, refrigeration system evaporation box and heating system accumulates a lot of dust, moisture, bacteria and other dirt, which causes damage and allergic reactions to the human respiratory system and the air conditioning system itself, and the air-conditioning system itself will also cause faults such as poor refrigeration effect and small air output. So, in general, the cabin air filter is cleaned every 5,000 km or 3 months, and the cabin air filter is replaced every 20,000 km or 12 months.

Summer is here, and everyone has a summer of mediation while driving. However, after half a year of useless empty adjustment, it emitted an unbearable odor. The smell is really unbearable for the stuffy interior environment.

In fact, this is the peculiar smell in the air conditioning system, and the dirt in the air conditioning system is mainly concentrated in the air duct of the air conditioner, the air conditioning filter element and the evaporation box. So, how to clean the air conditioning system quietly?

1.Replace the air filter.

This is the easiest way to get rid of empty odors because there is a lot of empty air filters and dirt on the cartridge, which usually has odors. Therefore, if the odor is not very severe, you can choose to replace the air filter.

2.Clean the air ducts.

If replacing the air conditioner filter still doesn't solve the odor problem, try cleaning the air duct of the air conditioner. There are two main steps to cleaning the air duct:

Spray the cleaning liquid and disinfectant special for cleaning into the air outlet, stop for a few minutes, and open the air to blow out. Remember to use a basin to catch the air outlet when it is open to prevent dirty water from flowing out of the car.

Spray the cleaning solution and sanitizer into the air intake. Stop for a few minutes and start the car to open the empty, then catch it with a basin to prevent dirty water from flowing out.

3.Clean the evaporator.

If both of the above methods fail, only the evaporator can be cleaned. If it's not severe, spray the cleaner through the air inlet into the evaporator and wait a few minutes for the dirt to flow out. If the evaporator has too much dirt, you can only go to a professional 4S repair shop or car beauty shop to disassemble and clean it for repair.
