What is the reason for the sour smell of the heater in the car

The smell often emitted by the air conditioner is actually the usual mold and bacteria, its ** is mainly in these places, air conditioning evaporation box, air conditioning duct and air conditioning filter, the reason why there are these unpleasant smells, is because of the use of a long time, dust and mold have accumulated in the filter element.

As a result, there is a peculiar smell in the air conditioning evaporation box and pipes, because every time the season changes, there is no timely cleaning, so that the mold can take root and sprout in it, and produce bacteria, which will lead to some unpleasant smells.

Clean and replace the air conditioner filter regularly, under normal circumstances, as long as the air conditioner filter is not replaced for a long time, it will not produce a large odor. If the odor is still noticeable after replacement, then it is time to clean the air conditioning ducts and evaporation tank.

Tips for getting rid of odors in the car:

1. Buy two lemons and put them in the car, if you want the effect to be faster, cut the lemons into slices, put a few slices in the air conditioner, and then turn on the air conditioner, which will soon make the air in the car clean and fragrant.

2. Burned honeycomb coal: put honeycomb coal, but it must have been burned, and the effect is particularly good. It is best to use honeycomb coal with a complete shape, referring to the principle of adsorption.

3. The peculiar smell of the new car is often a signal that the air in the car is polluted, and harmful substances such as formaldehyde and benzene may be being released. When you are not using the car, make a small bucket of water, add some vinegar, put it in the car, try it a few times, and the smell will gradually disappear. Here's why:

Water can adsorb formaldehyde, and vinegar can play a role in stabilizing formaldehyde.

4. Onion: Cut a few slices of onion, put it in a basin of water, stir it, and then place it in the newly renovated room to remove the odor. This method can be used in the car with a little flexibility. Cut the whole onion into four cloves and place in the car.

5. Turn on the air conditioner less, you can often open the car window to ventilate more and let the indoor air circulate, so that you can breathe fresh air.

"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."

In many cases, this is the case, where the hot air comes in and smells, but the cold air does not.

If there is a peculiar smell, it may be that the small animal has hidden food rot in the car, or there is a foreign object in the airway.

Try to ventilate for a long time, if the smell persists, then go to the master to see, if it is just the beginning, that is, the gas in the airway has been stuffy for a long time and has a smell to empty.

How did the landlord solve it? I'm having the same problem.

Causes of odors:

1. The air conditioner is often turned on at its coldest level.

2. The air volume is always the smallest.

3. Always use internal circulation.

Methods of prevention and control:

1. Try not to turn on the air conditioner as far as possible, and it is not good for the body.

2. Turn on the air conditioner, and the air volume should be placed above the middle range to speed up the flow of air around the condenser tube.

3. It must be based on external circulation, and it does not cost any oil, because the automobile air conditioning compressor is always on. What to do after a sour taste:

1. Turn on the air conditioner.

2. The temperature is adjusted to the highest.

3. The air volume is adjusted to the maximum.

4. Hold for 5 minutes and 10 minutes.

5. Just return to normal use, and pay attention to the use of air conditioners according to the prevention and control methods mentioned above.

--I've had this happen to me too, but it doesn't taste sour after opening it a few times. The above is the best answer I have seen, please refer to it.

Many vehicles smell odors when using heaters. So where do these smells come from and how to fix them?

There are several reasons why cars smell when using heaters:

One, because there is an evaporator.

Also called evaporation tank). The car's warm air mainly comes from the heat from the water tank, which is in the evaporator. Warm air is the cooling system of the engine, and in the process of cooling the engine, a blower is used to blow heat into the cab.

If it is for a long time, a small amount of moisture and dust may adhere to the evaporator, and the evaporator will become moldy, which will produce odors and also affect the air quality in the car.

Everyone must clean up on time at ordinary times. Keep the air in your car fresh.

Second, there is a peculiar smell in the air duct of the air conditioner. The inside of the air conditioner duct stinks due to damp mold. It is recommended to turn off the air conditioner switch, turn on the external circulation air, and continue to blow until the stop is 2 minutes, and then turn on the air conditioner every time. This method dries the moisture in the air duct and prevents mildew.

Third, the air conditioner filter has a peculiar smell. The air conditioner filter has a service life, and if it is broken, it needs to be replaced, otherwise it will also produce mildew and cause odor after a long time. And over time, the bacteria in it will gradually accumulate, which is not good for human health.

After the air conditioner is used for too long, dust will accumulate inside the machine's filter and copper sheet. After accumulating to a certain amount, a foul smell is formed. When the air conditioner is turned on, the smell of the air conditioner wafts into the air.

Therefore, daily driving should regularly check the air conditioning pipes or other parts for debris, dust or stains, and if so, use a special air conditioning cleaner to clean the air conditioning pipes. The cabin air filter is an easily overlooked component, and some car owners don't even know that the air conditioning filter in their car needs to be cleaned and replaced regularly.

A dirty cabin air filter not only filters dirty air, but also causes secondary pollution to the fresh air that enters the car. Therefore, when you usually use it, you must regularly clean your vehicle, maintain your car, keep the car ventilated, and prevent harm to people's health.

It may be that the external circulation is opened, it may be that there are water stains inside the air conditioning duct, the water stains are deteriorating, it may be that the filter screen is moldy, or it may be that long-term smoking has fallen the smoke and dust into the pipe, or it may be that the carpet seat interior is dirty.

It could be a problem with the air conditioner on the car, or it could be a problem with the air conditioning system, or it could be a problem with the evaporator. It could also be some bacteria and mold.

Your heater cabinet is covered with dust, which induces a lot of mold to grow on it, so there is a peculiar smell. You can only solve the problem by thoroughly cleaning the dust on the copper sheet of the heaterbox. However, this is very troublesome, there are a lot of things to disassemble, it takes a lot of effort, and it only takes ten minutes to tie it.

And by the way, clean the heating pipes.

Hello, this kind of problem is mostly the odor emitted by the air conditioner filter that has not been replaced for a long time. There is also the air conditioning air duct has not been cleaned, and the dirty things inside are moldy and issued, it is recommended to replace the air conditioning filter and clean the air conditioning air duct.

Part of the heat of the warm air is exchanged from the exhaust gas, so the cold air has no smell, this problem may also be caused by the damage of the exhaust gas circulation pipe, which is very common, and it is very common to repair it quickly and affect the health of the body.

Three ways to reduce odors:

First, turn off the air conditioner in advance when you are about to arrive at your destination, and turn on the natural air and external circulation;

Second, open the window for ventilation before starting each car;

Third, when there is a peculiar smell, use the cleaning agent to sterilize the external circulation air duct, and replace the filter element of the air conditioner.

For friends living in the north, the heating must be turned on as soon as you get on the car in winter, and it can be said that the winter life in the north is given by heating. However, sometimes you may encounter a smell as soon as the car turns on the heater, so what is the cause of the smell of the heater?

When the car is turned on, the heater smells?

There are several reasons why the car will smell when the warm air is turned on:

1. The air conditioner filter has not been cleaned for too long, and it cannot effectively filter pollutants in the air;

2. There are foreign objects in the air-conditioning pipeline or too much condensate produced by refrigeration in the air-conditioning pipeline, forming a damp and dark environment suitable for mold reproduction;

3. The smell of food residues falling on the carpet in the car or spilled desserts and drinks, and the damp carpet will also become a source of unpleasant auspicious smell.

What to do if the car smells bad

If you want to completely ** the smell of warm air, then we must first find the source of the odor.

Carpets in the car should be kept dry and clean, and it is best to be exposed to the sun regularly to reduce the production of mold.

We can also try to drive the car to a well-ventilated area and then turn on the doors and hot air switches to try to let the smell dissipate.

How to remove odors from the inside of the car

You can put some bamboo charcoal bags in the car, which can adsorb formaldehyde, benzene and sulfur dioxide and other toxic substances in the car, and can also absorb certain odors. Flowers, tea, high-quality car perfume and agarwood pendants can effectively alleviate the smell of alienation in the car.

Expansion: The heating system of the car is a device that sends the air inside the car or the outside air into the car into the heat exchanger to absorb a certain heat energy, thereby increasing the humidity of the air, and uses a blower to send hot air into the car to increase the temperature in the car. The function of the automobile air conditioning heating system is to send cold air into the heat exchanger, absorb the heat of a certain heat source, increase the temperature of the air, and send the hot air into the car.
