Do you have an unpleasant smell when you turn on the air conditioner in your vehicle?

Recently, the continuous high temperature has made the heat unbearable, and the first thing the friends do when they get in the car is to turn on the air conditioner. But recently, a partner told him that he found that the car air conditioner had an unpleasant smell when it was just turned on, so every time before getting in the car, he turned on the air conditioner of the car first, and waited for the air conditioner to blow for about 2-3 minutes before getting into the car. I think many car owners and friends will encounter this situation, what to do if the car air conditioner smells, do you usually have any tips for blowing the air conditioner?

When many car owners find that the air conditioner has a peculiar smell, they will use items such as perfume to cover up the smell. However, Guohe Express reminds that this is not a suitable way to maintain the car to remove the odor of the air conditioner, and it will treat the symptoms but not the root cause, and even make the odor more serious. Because the perfume is acidic, the smell is emitted and collects on the air conditioner evaporator, which is easy to mold and deteriorate, resulting in peculiar smells.

Let's talk about the way to remove the odor of the air conditioner for car maintenance.

1. When the air conditioner emits peculiar smells, it is likely that we have not replaced the air filter and air conditioner filter. The air filter and air conditioning filter are car air purifiers, and their main function is to filter out dust and other impurities, so that we can breathe healthy air in the car. If it is not changed for a long time, the surface will be filled with dust, and the adsorption function will be reduced, so that we will smell odors.

2. Clean the air-conditioning system.

Vehicles with a long driving life, there will be some mold in the air conditioning system more or less, it is possible that the air conditioning odor is emitted from here, it is recommended that car owners can clean up the air conditioning system with fresheners, or they can go to a professional car repair chain shop to clean up.

Car Maintenance: Tips for Blowing Air Conditioner.

1. When the car is about to reach the destination, first turn off the air conditioner and let the car blow the natural wind, which can make the temperature in the air conditioning pipe rise, keep the air conditioning pipe happy and dry, and prevent the generation of mold.

2. Occasionally adjust the air speed of the air conditioner to the maximum, so that the residual dust and impurities in the air conditioner are blown out to prevent rapid accumulation.

3. Clean and replace the air conditioning system and filter element regularly.

4. In the long-distance running, you can consider taking a break from the air conditioner if necessary, so that the pressure of the car refrigeration system will not be too high and cause damage, which is good for the maintenance of the refrigeration system.

In fact, the smell of the car air conditioner is more or less caused by our improper maintenance of the car. When you notice an odor, know the correct way to deal with it, and it is best to go to a car repair shop to check it. Finally, it's important to have the right car maintenance tips.

Reason analysis: The refrigeration principle of air conditioning is to absorb heat through the rapid evaporation of refrigerant, so that the temperature of the air flowing through it drops rapidly. Due to the low temperature of the evaporator and the high temperature of the air, the water molecule particles in the air will condense into water droplets on the evaporator, and the dust in the air or the small fluff on the clothes, seats and other substances are easy to attach to the surface of the condenser, which will lead to mold and bacteria will multiply in large numbers.

Long-term inhalation of such air by the human body will affect the health of the driver and passengers, so the air conditioning system should regularly replace the air conditioning filter element and clean the air passage.

Because the air conditioner has a large amount of foreign matter accumulation, it needs to be cleaned in time.

It's time for your cabin filter to be replaced!

There is a peculiar smell when the heating air conditioner is turned on in winter, how to clean it by the old driver?

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.

The air conditioner filter is generally replaced once a year, but it also depends on the situation, and it is possible to change it once every three months when the air conditioner is used frequently or the external environment is very poor. The air conditioner filter is dirty."

The unpleasant smell of the vehicle when the air conditioner is turned on may be caused by the clogged air conditioning pipes. It is recommended that you go to a four-S shop or an auto repair shop to check it out.

Because the air conditioner evaporation box and ventilation duct are moldy, when the air conditioner is turned on, the air will enter the car through the evaporation box to cool down, in the process of passing through the air outlet, bacteria, dust and other things in the air will enter the evaporation box and ventilation duct, and in the long run, there will naturally be a smell when the air conditioner is turned on.

If the air conditioner in the car smells, you have to consider whether the air conditioning filter is dirty, and many car owners never clean the car air conditioner after using it. And the air conditioner filter needs to be cleaned regularly, if it is not cleaned regularly, it will produce a lot of dirt and bacteria, so the air conditioner will have a peculiar smell when it is turned on.

The wrong practice of using an air conditioner.

1. Don't turn on the air conditioner all winter.

Winters are warmer in some areas, and some car owners don't use air conditioning all winter. In fact, not using the air conditioner for a long time will cause the rubber ring to deteriorate, and the lubricating oil on the internal parts of the air conditioner will also dry out.

2. The direction of the air outlet of the air conditioner can be adjusted at will.

Some car owners do not pay attention to adjusting the direction of air conditioning when using air conditioning, which is not conducive to giving full play to the best effect of air conditioning. According to the principle that cold air sinks and hot air rises, the correct approach should be to turn on the air outlet upwards when the air conditioner is turned on, and the air outlet is downward when the heating is turned on.

3. Turn on the air conditioner for a long time.

Some car owners often turn on the air conditioner after getting on the car, and the use of the air conditioner for a long time will make the condenser pressure too large, which will cause loss to the refrigeration system, so each time the air conditioner is used for too long, if the temperature in the car has reached a comfortable temperature, you can turn off the air conditioner and turn it on again after a while.

It depends on whether it's a new car or an old car.

1. The reason for the peculiar smell of the new car is that the evaporator of the new car will use glue and other chemical agents during assembly, which will emit peculiar smell from the air duct and pollute the air in the car.

2. The reason for the peculiar smell of old cars is that the residual moisture in the pipes of the air-conditioning system and the dust in the air combine to produce mold; The aircon filter is too dirty.

New car odor solution:

1. Put some bamboo charcoal in the car.

2. Place apples or lemons.

3. Install a car electronic aromatherapy.

Old car odor solution:

1. Clean the air-conditioning system.

2. Clean or replace the air filter.

3. After cleaning, place bamboo charcoal, lemon, electronic aromatherapy, etc. according to the method of the new car to ensure that the air in the car is fresh and pleasant.

In addition, in order to turn on the air conditioner in the future, pay attention to the following points:

1. The heating temperature in the car in winter should not be too high, for two reasons: first, the temperature difference between the inside and outside of the car is too large, and people are prone to cold and discomfort; Secondly, too high ambient temperature is easy to make people drowsy, which is not conducive to driving safety.

2. 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.

3. Use the external circulation in the area where the environment is relatively clean to purify the air in the car, and do not forget to use the internal circulation system when driving in the area with the dirty external environment.

4. Frequently check and replace the pollen filter and clean the air conditioning evaporation box, which can effectively remove the odor and bacteria of the air conditioning system.

5. In the process of using the air conditioner, it is necessary to prevent condensation, and the air conditioner will blow out the moldy smell after cleaning, because the condensation in the air conditioning pipe forms a dark and humid environment, which is very suitable for the reproduction of mold. The way to prevent it is to turn off the air conditioner a few minutes before parking and turn on the natural air later, so that the temperature in the air conditioning duct rises before stopping, reducing the temperature difference with the outside world and keeping the air conditioning system relatively dry.

6. Vehicles equipped with manual air conditioning equipment also need to turn on the air-conditioning system frequently in winter to protect the performance of the air-conditioning system.

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.

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.

1.The reason why new cars produce odors is that other chemicals such as evaporators and glue are used during assembly, which can emit odors from the air ducts and pollute the air inside.

2.The reason for the peculiar smell of the classic car is that the residual water in the pipeline of the air conditioning system and the dust in the air body combine to produce mold; The empty filter is too dirty.

The musty smell mainly comes from the empty adjustable evaporator. Darkness, humidity, and warmth are the top three conditions for mold growth. The air control system has the above conditions, and almost all automobile air control can not avoid mold on the evaporator.

The wetter and warmer the region, the more likely it is to travel and cultivate, such as the southern region and Beijing during the rainy season.

When the air passes through the evaporator blades, the water vapor in the air will condense into water droplets on the blades, and the condensed water can absorb some of the impurities and dust in the air leading to the cab air. Typically, the water that has absorbed impurities and dust flows to the bottom of the empty heating unit housing and is discharged through the conduit to the outside of the vehicle. The "leaky" liquid we see under the car in the summer is actually this water that absorbs impurities.

Millions of car purchase subsidies.

The reason for the peculiar smell of the car air conditioner is that the air conditioner filter has not been cleaned for a long time and the outside air flows through the air conditioning system ducts.

1. The air conditioner filter has not been cleaned for a long time, and the air is humid in the rainy season, which causes the air conditioner filter to be humid and warm, resulting in mold breeding and musty smell.

2. The outside air flows through the air conditioning system pipes, which will combine a small amount of residual moisture with dust in the air, and if it is not cleaned for a long time, it will also produce mildew and produce sour and rotten odors.

Here's how to fix the smell of your car air conditioner:

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

2. Master the correct way to turn on and off the air conditioner, generally 5 minutes before parking, it is best to turn off the air conditioner, 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 because of the temperature difference after parking, so that the air conditioning pipe can be dried and block the breeding of mold and fungus.

Car air conditioners should be used correctly:

1. First of all, start the empty waiter to adjust the external circulation. It is advisable to put the windows down completely, ventilate the car, and close the door when the engine heats up after a few minutes. At this time, don't be in a hurry to close the window, turn the air supply of the empty cover to the maximum, so that the hot air in the car will almost dissipate after two or three minutes of driving, and then press the air conditioning button, the cooling effect will definitely be much better.

2. Do not use the air conditioner for a long time after parking. Some car owners close their doors and windows, turn on the air conditioner, and rest in the car to cool down. This can easily lead to an increase in carbon monoxide concentrations and poisoning in the car.

3. The direction of the air outlet of the air conditioner is also very particular. According to the physical principle of air circulation, cold air sinks and forms a convection current with hot air. Therefore, when the air conditioner is turned on, the air outlet will be upward, allowing the convection of hot and cold air in the automotive market, increasing the cooling rate.
