    After long-term air adjustment, a certain amount of dust will accumulate in the indoor filter and copper sheet, and when it accumulates to a certain amount, it will produce peculiar smells. When the air conditioning is turned on, odors drift into the air.

    When the air conditioning is cooled or heated, there will be moisture inside the indoor unit. Therefore, after the air conditioning system is turned off, the air conditioning system that does not have the function of drying and mildew prevention will of course be stopped immediately, so that the moisture inside will not disappear, mold will be produced for a long time, and mold will occur naturally.

    The room is not always well ventilated, the air is not good, or the dust floating in the air also smells. When defrosting, the compressor will run at high speed, which may be the smell of high temperature from the main channel of the plastic on the compressor.

    Some air supply terminals are not high-efficiency filtration systems, such as computer rooms and hotel rooms. Although the interior is well decorated, the air is fresh, and the air conditioning air supply is 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 empty interior.

    After the air conditioning system was activated, the bacterial concentration and odor in the room increased. This is because the condensate retained on the heat exchange coil, ribs, and surrounding components slowly evaporates, creating high humidity (and high temperature) conditions around the coil, making it a suitable environment for microorganisms to thrive.

    Clean the evaporator of the internal machine, open the movable case, remove the strainer and look at the evaporator with metal fins. Prepare a special empty bottle of detergent (usually in large supermarkets**). In the power-off state, the detergent is evenly sprayed into the evaporator.

    Wait 15 minutes before starting the air conditioning and the dirt will follow the condensate.

    In fact, for friends with poor hands-on ability and little understanding of the internal structure of air adjustment, it is best not to clean up the air adjustment by yourself, so as not to be embarrassed to disassemble and assemble.

    I think it's because the air conditioner will accumulate some dirt such as dust during long-term use.

    Because the air conditioner is not used for a long time, it will gradually cool down, and it will produce a variety of different flavors.

    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. As the temperature of the evaporator is low, while the air temperature is high.

    Water molecule particles in the air can condense into water droplets on the evaporator, while dust or clothing in the air. Substances such as small fluff on the seat tend to adhere to the surface of the condenser, which can lead to mold and bacteria.

    Solution: 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 and clean the air channel.

    Causes of odor from air conditioners:

    1. The air conditioner that has not been used for a long time will also produce peculiar smell when it is started, because the condensate retained on the heat exchange coil, fin and its surrounding parts slowly evaporates, forming a high temperature condition suitable for the reproduction of microorganisms around the coil, and a large amount of gas produced when the microorganisms reproduce will be released under the drive of the air conditioning system and become the source of foul odor.

    2. If the air conditioner runs for a long time, the air conditioner's filter screen and copper sheet will squeeze a certain amount of dust, and the heat exchanger fins will also be full of dust, which will cause blockage after accumulating to a certain amount; A certain odor is generated, and as the air conditioner is turned on, the odor from the air conditioner will drift into the air.

    3. 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.

    Air conditioning maintenance during normal hours

    1. Remove debris from the vent to ensure proper ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents unobstructed.

    2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the internal machine, so as to achieve the purpose of removing dust and harmful accumulation of multiplying germs. However, it should be noted that since the heat sink is a thin aluminum material, it is easy to deform after being stressed, so it should be carefully brushed.

    3 Clean the dirt on the filter screen. When cleaning the filter, first cut off the power supply, and then open the air inlet grille; Take out the filter, wash the filter with water or a vacuum cleaner, the water temperature should not exceed 40 degrees, wash it with a hot damp cloth or neutral detergent, and then wipe it with a dry cloth, and do not wash the filter with insecticides or other chemical detergents.

    The smell of the air conditioner is caused by the improper use of refrigeration in summer, and the correct way to use it is to turn off the AC about 3 minutes before arriving at the destination, turn on the external circulation, and then open the air volume to the maximum, and blow dry the air conditioning pipeline. When the air conditioner has just been turned on and the wind blowing out has not yet cooled, it will smell a smell similar to mildew and soot. Because of the long-term dampness of the management, there is mildew inside, and it is generally empty.

    The solution to the cause of the smell of the air conditioner is as follows:Reasons: 1. The temperature rises, microorganisms multiply, and after the air conditioning system is started, the indoor bacterial concentration and odor increase, which is due to the slow evaporation of the condensate retained on the heat exchange coil, ribs and their surrounding parts to form high humidity (and high temperature) conditions around the coil, and become an environment suitable 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.

    2. Dust adheres to the system, the system does not run for a long time, and the heat exchanger ribs are nearly full. 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.

    Clean the evaporator of the inner machine, open the movable shell, remove the filter, you can see the evaporator with metal fins, prepare a bottle of special air conditioning cleaner, spray the detergent evenly into the evaporator in the state of power off, wait for 15 minutes to start the air conditioner, and the dirty things will flow away with the condensate. Find a small brush to sweep the dust off the air conditioner's air outlet, and then install all the removed items back on.

    1. The air conditioner has been used for a long time, and 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 when the air conditioner is 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 also stop running, so that the internal moisture will produce mold in the long run, and there will naturally be a peculiar smell.

    3. The system has not been running for a long time, and the heat exchanger ribs are nearly full.

    4. Some air supply filter systems, fresh air and air conditioning air supply 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.

    Odor treatment. The air conditioner should not only be used, but also be regularly maintained and cleaned, especially the filter should be cleaned regularly, not only the filter, but also the heat sink is a common sanitary dead end, and if it is not cleaned for a long time, it will also breed bacteria and cause the smell of the air conditioner.

    While cleaning the filter, it is necessary to regularly clean and disinfect the radiator of the air conditioner, clean it in place, and not let go of every corner, so as to ensure that the air conditioner blows clean air.

    Before the air conditioner is turned on for the first time, it should be thoroughly cleaned and disinfected once a month, and in case of frequent use, it should be cleaned and disinfected once a month.

    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.

    Dust in the air can also smell, or the air in your room isn't too good. At the time of defrosting, the compressor will run at high speed, which may be the smell of the plastic on the compressor when it encounters high temperatures.

    How to remove the odor of the air conditioner

    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.

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

    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, wait for 15 minutes to start the air conditioner, and the dirty things will flow away with the condensate.

It is believed that the large amount of dust brought by fresh air and accumulated in these places not only carries microorganisms, but also provides indispensable nutrients for microorganisms to multiply, resulting in odors in air conditioners. This answer applies to most of the air conditioner models from brands such as Midea, the KY-15, the N7Y-Pha, etc.

    The smell of the air conditioner is very good! Hello, I'm glad to answer for you<> dear, the smell of the air conditioner smells very good because: reason 1, after the use of the air conditioner for many years, the indoor screening and copper inside will reduce a certain amount of dust, so after the accumulation of a certain amount of odor generated, open the air conditioner, the smell of the air conditioner will be dispersed to the air.

    Because after the air conditioner is refrigerated and heated, in many cases, there will be moisture inside the indoor unit, so when the air teasing is turned off, the air conditioner will stop immediately without dry mold function, so the internal moisture is always there, and it will produce molds for a long time, and there will naturally be a musty smell. Reason 34The system was not running for a long time, and the heat exchanger fins were almost clogged.

    Some inefficient filtration systems at the end of the air**, such as computer rooms and hotel rooms, are well decorated. Fresh air and air conditioning filtration, but dust can still be found near some indoor air channels and window sills, a layer of dust on the surface is stuck to the surface of the internal parts, the air conditioning system starts, indoor bacteria and odors, but the concentration increases, this is due to the heat exchange coil, the ribs and the surrounding area of the retained condensation slowly evaporates to form coil mold fingers closed under high humidity and high temperature conditions, suitable for microbial breeding environment, cultivating a large number of gases generated due to the sudden release of system drive, bad odor **. It is believed that the large amount of dust that is blown by the breeze in these places not only carries microorganisms, but also provides them with the necessary nutrients for their reproduction.

    It is not enough to clean the filter, cleaning and disinfection of the heat sink is key. At present, most households usually only stay in the filter layer when cleaning the air conditioner, in fact, this cannot completely remove the pollution caused by the air conditioner. Since the filter only filters out a portion of the dust, there will still be some dust that accumulates in the radiator through the filter and accumulates a lot of bacteria.

    To understand the real cause of pollution of air conditioners, we can do 1 step to clean the air conditioner at one time, clean the filter of the air conditioner and clean and disinfect the fins at the same time, so as to effectively inhibit the radiator bacteria from polluting the indoor air. In addition to developing the habit of cleaning and disinfecting the air conditioner every time, it is also necessary to clean and disinfect the air conditioner fins regularly. In the season of changing seasons every year, the air conditioner should be thoroughly cleaned and disinfected before the first start-up.

    However, in the months when air conditioners are frequently used, such as summer, it is necessary to clean air conditioners regularly as people may stay in air-conditioned rooms for a long time, and indoor air quality directly affects our health. The easy way to do this is to disinfect your air conditioner once a month. Hope mine can help you <>
