What should I do if there is a peculiar smell when I turn on the car air conditioner every time I st

There is a peculiar smell when the car air conditioner is turned on because too many bacteria grow in the ducts, evaporation box and air filter element of the car air conditioner, and too much dust accumulates, and the gases, excrements and dust metabolized by the bacteria enter the car through the air conditioning outlet.

How to solve the odor of car air conditioner? 1.For slight odors, you can park the vehicle in the sun, turn the knob to the warm air, then turn the fan to the highest setting, open all the doors, exhaust the dirty air outside, and run for about 5 minutes to effectively remove the odor of the car air conditioner.

2.For new cars, the windows should be opened frequently for ventilation, because the new car evaporator will use chemicals such as glue during assembly, which will emit odors from the air duct and pollute the air in the car.

3.If bacteria remain in the duct, an odor will occur. Using an air conditioner duct cleaner can remove odors from the air duct.

The cleaning method is also very simple. After parking the vehicle in a place with a good air environment, turn on the external circulation switch, turn on the air conditioner to the natural ventilation gear, and then spray the cleaning agent evenly into the air supply outlet air duct. After a few minutes, open the windows and turn on the air conditioner for complete ventilation.

4.Clean the air conditioning system.

This includes cleaning dust and dirt from air conditioner intake pipes and evaporation tanks. An air conditioner evaporator that has not been cleaned for a long time.

Covered with dust and fine hairs. It needs to be carefully cleaned with a brush. If necessary, replace the cabin air filter.

Ducts, evaporation boxes, and air cleaners for automotive air conditioners.

It's inevitable in a dark, damp environment. If the owner can have good driving habits, it can effectively inhibit the growth of bacteria. During daily driving, car owners turn off the air conditioning and refrigeration system a few minutes before parking.

The heat from the natural wind passes through the evaporation tank and causes water vapor on the evaporation tank.

It dries out and makes it difficult for bacteria to multiply.

For slight odors, park your vehicle in the sun, adjust the knob to warm air, then turn the fan to the highest setting, open all doors, and exhaust dirty air outside. This can be done not only with ultraviolet light.

Disinfecting a car can also effectively clean dust from the air duct. Running for about 5 minutes can effectively remove the odor of the car air conditioner.

Evaporation box The outside air flows through the evaporation box, it will inevitably bring moisture and dust, most of the water and dust will be discharged from the car through the air conditioning drainage, but there is still a small part may be attached to the evaporation box, and it will produce mildew and rot smell after a long time.

Air conditioner filter The air conditioner filter is mainly to filter the air, and the air will reach the evaporator only after the air conditioner filter, so the air conditioner filter plays the first protective role. In addition to filtering dust, the air conditioner filter will also absorb odors, and if you do not change the air conditioner filter for a long time, the air volume will not only become smaller, but the odor will also become heavier.

Air Conditioning Air Duct Air conditioning air duct is a ventilation duct, which is easy to accumulate dust, but it is often overlooked.

Outside air The smell of the air conditioner also has a lot to do with the use environment, for example, if you turn on the external circulation when the air quality is not very good, then the air conditioner's own filtration system is not so efficient.

It needs to be cleaned up, there must be something wrong with the air conditioner, and it needs to be cleaned, so that it can be effectively avoided and respiratory infections can be avoided.

You should often turn on the air conditioner, you can also go to the 4S store for cleaning, or spray some perfume. You can also turn on the natural breeze or warm air.

If the air conditioner has an odor, you can open the window for ventilation, and you can install an on-board air purifier in the car.

We put some sachets in the car and open the windows when the air conditioner is turned on, so that there is no smell in the car.

The solution to the odor of car air conditioners.

1. Check the air outlet duct of the air conditioner.

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

2. Check the air conditioner filter.

Air conditioner filters are generally replaced once a year, but if sandstorms or other bad weather occur frequently, it is necessary to replace them once every few months. If the surface of the air filter is dirty, you can simply blow it, but if it is already very dirty, it is not recommended to clear the air filter, because cleaning will cause the filter eye to become larger, so that the filtration effect is significantly reduced.

3. Mold on the evaporation box.

This situation is the most difficult to deal with, generally speaking, you can only turn to a professional auto repair station, ask them to do an air conditioning cleaning, they are in the case of the air conditioner on, spray a special air conditioning cleaning agent to the blower, but this process must not be operated by yourself, otherwise it is easy to damage the blower.

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.

The air conditioner in the car has not been cleaned for a long time, resulting in the air conditioning pipes and air conditioning filters in the air conditioner being filled with bacteria and dust, and the air conditioning evaporator box in the car is not cleaned, resulting in mold and dirt. The other condition is caused by the air conditioning ducts. If the air conditioner is not used for a long time, the water vapor inside the air conditioner will condense into water droplets, which will mold over time in a humid environment, so there will be a special smell inside the air conditioner.

In this case, it is recommended to go to a place such as an automobile assembly shop to thoroughly clean the air conditioning system.

Generally speaking, the smell of the car will only appear after the car air conditioner is turned on, which is a problem with the car evaporation tank. Now some repair shops or 4S shops are equipped with spray guns for visual cleaning and cleaning of evaporation tanks. The endoscope sticks into the car's evaporation box, and you can see dust, hair, and other dirt on the evaporation box on the screen.

The air cleaner should be replaced. Replaceable activated carbon filter for air permeability. It absorbs specific odors.

In addition, if the activated carbon conditioning filter element is not replaced for a long time, when the hot air is turned on, there will be a special odor, indicating that the adsorption of the activated carbon is saturated, and the air conditioner filter must be replaced over time.

The peculiar smell of an air conditioner is often caused by these conditions. If the air conditioner is not lit for a long time, the air duct will produce dust; The air conditioner filter has not been replaced for a long time; In the summer, when the air conditioner is turned on to cool, the air duct condenses the cold air. When the fire is extinguished, the outside temperature rises, causing damp, moldy air to enter the ducts.

In the winter air conditioning system ducts and air intakes, after turning on the hot air heating, the water evaporates and dries, producing a rubber odor. At first glance, it smells like pasta and then disappears, the main reason being that after the last time the air conditioner was used, it directly stopped the engine, causing the humidity inside the air conditioner to linger. Think of the smell of dampness in a confined space.

Please turn off the air conditioner in advance before you arrive at your destination next time.

When the air conditioner was first turned on, there was a special smell. First of all, the cabin air filter needs to be replaced, and if you want to replace the big brand air conditioner filter with activated carbon, then the specific odor will be reduced. Secondly, if there is a specific odor, it is the odor produced by the evaporation tank molded in the car.

You should find a professional car repair shop to clean the visible evaporation tank. I hope it solves your problem right away! Usually in a humid environment, the filter element of the air conditioner is not replaced, and the external environment is poor.

In northern regions, it is better to open the internal circulation and change the filter element frequently.

The main reason is that 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 condense into water droplets, and the humid environment is the most likely to breed bacteria and mold.

The main reason is that 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 condense into water droplets, and the humid environment is most likely to breed bacteria and mold, resulting in musty smell.

Tips to prevent musty smell in your air conditioner.

Turn on the air conditioner in summer, and before stopping and turning off the engine, you should turn off the air conditioner compressor in advance and adjust the mode to external circulation. Let the hot air blow dry the moisture in the aircon air-conditioning tunnels, so that your aircon will never get damp and harbor bacteria, which can cause odors.

Specifically, a few minutes before arriving at the destination, the A C switch is turned off in advance, and the mode is adjusted to external circulation, so that the moisture in the air conditioning duct can be dried after a few minutes. If the air conditioning ducts are kept dry, there will be no breeding ground for bacteria, and the problem of odor will be easily solved.

Car Air Conditioner Type:

1. According to the driving mode, it is divided into: independent (a special engine-driven compressor, with large refrigeration capacity and stable work, but high cost, large volume and weight, mostly used for large and medium-sized buses) and non-independent (air conditioning compressor is driven by the automobile engine, and the refrigeration performance is greatly affected by the engine work, and the stability is poor, and it is mostly used for small buses and cars).

2. According to the performance of air conditioning, it can be divided into: single function type (refrigeration, heating and ventilation systems are installed and operated separately, do not interfere with each other, and are mostly used in large buses and trucks) and integrated cooling and heating (refrigeration, heating, ventilation share blowers and air ducts, which are controlled on the same control board, and can be divided into a combination of cold and warm air working separately and a mixed temperature control type that can work at the same time. Cars are mostly used with mixed temperature control).

According to the control mode, it is divided into manual type (toggle the function key on the control board to control the temperature, wind speed, and wind direction) and electro-pneumatic adjustment (using the vacuum control mechanism, when the air conditioning function key is selected, the temperature and air volume can be automatically controlled within the predetermined temperature).

3. According to the control mode, it can be divided into: automatic adjustment (using the calculation and comparison circuit, through the sensor signal and pre-setting signal to control the adjustment mechanism to work, and automatically adjust the temperature and air volume) and the automatic adjustment of microcomputer control (with the microcomputer as the control center, to achieve all-round, multi-functional optimal control and adjustment of the air environment in the car).

Generally, cars have this problem in summer, which is normal. So why? In summer, when the cold air is turned on, the evaporator not only cools down and cools, but also condenses water.

If you don't turn off the AC ahead of time, let the evaporator return to room temperature, and let the fan blow away the moisture, then the evaporator will "stay wet" for a period of time after you turn off the air conditioner. High temperature, humidity, mold growth frantically, as soon as the fan is turned on, there is a musty smell. Not only the evaporator, of course, but also the ventilation ducts.

Driving in the summer, you can hardly sit in it if you don't turn on the empty switch. After sun exposure, the temperature in the car can reach 50-60 degrees, but sometimes when you turn on the empty switch, you will feel a strange smell. So, what can be used to solve the odor in the empty switch?

Why do car empty tunes smell weird?

After the air is opened, when the cold air body encounters the empty water molecules in the gas, it is easy to produce water droplets to stay in the air conditioning tube, and the humid environment is very easy to breed bacteria and mold.

Tips to prevent air odors.

Do not turn off the engine when parking with the empty switch in summer. At this time, press the AC button in the car, first turn off the empty switch in the car, and then turn on the external circulation mode, and use the hot air body to directly blow out the residual moisture in the air switch system. Your air sound will never get wet, it won't grow bacteria, and it won't produce odors.

Keep the pipes dry so that there is no soil where bacteria can grow, and the problem of odor is easily solved. Of course, it is also possible to do this in advance when you are about to arrive at your destination, which also saves some time.

Open the windows before opening.

In summer, the temperature is very high. At this time, when the vehicle is exposed to sunlight, benzene, formaldehyde and other toxic gases will be emitted from the vehicle. At this time, if you turn on the empty switch as soon as you enter the car, you may inhale these toxic gases.

Here's the right way to do it. When using the vehicle, if the vehicle is exposed to sunlight, do not turn on the empty switch as soon as you get into the vehicle. First, open all the windows, turn on the blower, then close the doors and windows for a few minutes, turn on the empty switch.

Not only does this release toxic substances, but it also helps the car to cool down quickly.

Tilt and blow upwards.

If Zhenshan wants to let the car cool down faster, it is to choose to blow up obliquely, so as to use the law of hot air rising and cold air falling to cool down the car from top to bottom.

Switching between inside and outside defects.

When driving for a long time, it is necessary to master the switch between internal and external circulation. The internal and external circulation function can control the air quality in the car, and the air can help keep warm. However, it is also necessary to judge whether the outer loop can be opened according to the environment at the time.

If there is a traffic jam on the city road, it is not advisable to turn on the external circulation, so that the exhaust gas of other vehicles can easily enter the car.

Millions of car purchase subsidies.

The smell of the car air conditioner is because when the car air conditioner is working, because the temperature of the evaporation box can be as low as nearly 0 degrees Celsius, which is equivalent to a refrigerator, the breeding of fungi is not obvious, once the compressor stops working, the refrigerant stops circulating, the temperature of the evaporation box rises, and the environment on its surface becomes warm and humid, which is the hotbed of fungus breeding. The way to solve the odor: as long as a few minutes before each flame-off, manually turn off the air conditioner refrigeration (usually the AC button), but keep the air conditioner blower running for a period of time (that is, keep the fan on and continue to blow for 1 to 2 minutes), so that the air conditioner evaporation box rises to the ambient temperature and evaporates the moisture on its surface as soon as possible, so as to avoid its moist surface becoming a breeding ground for fungi, and the odor will disappear.
