Why does the air conditioner smell sour?

1.Perfume is useful for shading the smell, but it cannot be sterilized.

The statement of honeycomb coal, its flavor absorption principle is correct, but it is not practical, unless you put the used honeycomb coal neatly and neatly.

Place at the air outlet.

To get rid of odors, the most critical issue is to get rid of the odor source, eliminate bacteria, and live a healthy life!

2.The gas emitted by the outdoor unit of the air conditioner is non-toxic, and it is the air conditioner condenser that cools the hot air, but the air conditioner outdoor fan motor with a higher air temperature is the non-toxic hot air.

Dirty filter dust, dust accumulation, evaporator ribs, and condensate pans can breed and deposit mold during long intermittent periods, the so-called earthy or musty odor. If this kind of odor occurs, it can be completely eliminated through normal cleaning and maintenance.

In the refrigeration mode of inverter air conditioner, when the indoor temperature reaches the set temperature, the outdoor unit stops running, and the air odor will appear when the indoor unit is switched to air supply mode. In this case, the odor is often difficult to eliminate with normal cleaning methods. It may be caused by the hydrophilic aluminum foil coating material used in the heat exchanger of the air conditioner room.

At present, the common method is refrigerant heat exchange components.

Precautions for the use of air conditioners.

The air conditioner cleaning place is a humid place, the rated leakage action current of the leakage protector should not be greater than 15mA, the rated leakage action time should not be greater than that, the cleaning shell, handle, plug, switch and load line must be intact, and the corresponding safety protection equipment and appliances must be worn and used correctly according to the regulations.

If the air conditioner is to be used for a long time without use. Be sure to clean all aspects of the air conditioner. It is also necessary to do a certain inspection, after the cleaning of the air conditioner, only turn on the fan of the air conditioner and run for about 1-2 hours, so that the inside of the air conditioner is not dry at all, and then use a dust jacket to cover the air conditioner.

What causes the sour smell of an air conditioner? I'll answer that if your air conditioner has a sour smell, then there is a problem with the air conditioner, please ask the drilling industry personnel to repair it.

The sour smell of the net and stagnant water that has not been cleaned for a long time.

The air conditioner's filter and water tray should be cleaned frequently.

Taking Gree air conditioner as an example, the reasons for the sour smell of the air conditioner are as follows:

1. If you do not use the air conditioner for a long time, and when you use the air conditioner again, you find that the air conditioner has a sour smell, it may be because the refrigerant of the air conditioner or the lubricating grease of the air compressor is oxidized, and the high temperature is generated to decompose the chemical oxides when you work again, resulting in the sour smell of the air conditioner.

2. It may be that when the air conditioner is started, the condensate retained on the heat exchange coil and other parts of the air conditioner is formed after the dual action of temperature and humidity, and this microorganism will produce a sour smell under the operation of the air conditioner, so the internal evaporator of the air conditioner also needs to be cleaned regularly, and the sour smell can be removed after the internal evaporator is cleaned.

3. The air conditioner has a sour smell, which may be because the filter screen of the air conditioner has not filtered the dust, and then the dust has mildew, so there will be a sour smell.

It should be noted that this answer applies to most of Gree's air conditioner models.

If you don't use the air conditioner for a long time, it's best to use the natural wind for more than ten minutes when you use it for the last time. Otherwise, the water vapor in the air conditioner will remain, and it will become moldy and smelly. Therefore, even if you don't turn on the AC, it is recommended to turn on the fan frequently, after all, the air from the fan is filtered, which is cleaner than the air coming in from the window.

But it's strange that some people buy car purifiers separately, and that stuff compares.

1. Causes of peculiar smell: 1. Due to long-term use, the filter screen and copper sheet will squeeze a lot of dust, and after a certain amount, it will produce peculiar smell, which will drift into the air with the air conditioner turned on. 2. After turning on the refrigeration, if there is moisture in the room, when the air conditioner is turned off, the drying and mildew prevention function will stop running, so that the internal moisture will produce mold for a long time, and it will naturally have a peculiar smell.

3. The system has not been running for a long time, and the heat exchanger ribs are nearly full. 4. Some non-high-efficiency filter systems at the end of the air supply, fresh air and air conditioning are filtered, but dust can still be found near some indoor air supply outlets and on the surface of window sills. 5. After the air conditioning system is started, the condensate retained on the heat exchange coil, ribs and their peripheral parts slowly evaporates to form high humidity conditions around the coil, which becomes an environment suitable for the reproduction of microorganisms.

It may be that there has been no cleaning for a long time, the refrigeration mode is in the air supply mode, or the condensate has not been drained.

The air conditioner has not been cleaned for a long time, resulting in thick dust on the filter screen, and the evaporator ribs and condensate tray may also breed a large number of bacteria during the use of a long intermittent period, and the internal components of the air conditioner have become a hotbed for bacteria breeding and spreading if they are not cleaned for a long time. In this case, the sour smell of the air conditioner is in these bacterial metabolites, because it contains sour substances.

When the room temperature reaches the set temperature of the air conditioner, the external unit starts to stop running, and the indoor unit will be in air supply mode, which will send out a sour smell, and some people will even think that it is the smell of dead rats in the pipe.

It is also possible that the condensate generated during refrigeration in the air conditioner is not drained cleanly, resulting in a peculiar smell after a long time. Studies have reported that there are nearly 50 kinds of volatile substances in air conditioning condensate, and some of these compounds are phenolic and benzene substances, so there will be a special odor.

The reason for the sour smell of the air conditioner is the contamination of the air conditioner filter, the problem of the air conditioner plumbing, the corrosion of the water tank and evaporator, and the lack of good indoor ventilation.

1. Pollution of air conditioning filters.

Air conditioner filters are an important part of dust, pollen and other filter substances in the air. If it is not cleaned and replaced for a long time, some bacteria and mold will grow, and these bacteria and mold will produce a sour gas, which will cause the air conditioner to emit a sour odor.

2. Air conditioning duct problems.

There may be dirt or bacteria in the air conditioning ducts, and when the air conditioner is running, the moisture in the internal pipes often provides a breeding ground for bacteria and mold to survive, which will produce odors and be transmitted to the room with the hot and cold air of the air conditioner.

3. Corrosion of water tank and evaporator.

The water tank and evaporator in the air conditioner are the parts of the closed circulation of water vapor, and the long-term existence of water stains, as well as poor water quality, will cause dirt deposition, corrosion, and thus produce acid pre-chain nuclear odor.

4. There is no good indoor ventilation.

Not having good indoor ventilation can lead to low indoor air quality, which can produce a sour odor. In winter areas, it is necessary to keep the indoor airtightness high, so that air pollutants are more likely to accumulate.

Maintenance tips for air conditioners

1. Remove debris from the vent.

The debris of the air conditioning vent must be cleaned up, so as to ensure the effect of ventilation, and it is also necessary to see whether the outdoor machine is loose, whether there are foreign objects in the outdoor ventilation grille, and the unobstructed vent is very important for the normal use of the air conditioner.

2. Check other items.

In addition to the maintenance of air conditioners, you need to pay attention to the above maintenance methods, you also need to check the switches, plugs, plug boards and power supply lines, for the parts that are easy to be damaged, you should also check it, such as photocatalysts, sterilization and temperature removal and air guide plates and other parts must be checked to see if there is any abnormal situation, only these parts are good, the air conditioning can operate normally, and you can find professional technicians to maintain air conditioning, which will be more secure.
