Now, the use of air conditioners is very common in many households. The heat and heat are very unbearable. In summer, I believe that many people are inseparable from the air conditioner. However, in the process of using air conditioners, some problems will inevitably occur. Have you ever found that the air conditioner has been used for a long time, and the air conditioner will emit a strange smell? What is the reason? How to deal with this odor phenomenon?

The air conditioner has a peculiar smell

The reasons for the peculiar smell of air conditioners are generally as follows:

Reason 1: When the air conditioner is running for a long time, a certain amount of dust will accumulate inside the filter screen and copper sheet of the air conditioner, and the fins of the heat exchanger will also accumulate dust, causing blockage after a certain amount of accumulation; a certain odor , When the air conditioner is turned on, the smell from the air conditioner will float into the air.

Reason 2: After the air conditioner cools and heats, in many cases, there will be moisture inside the indoor unit, so when the air conditioner is turned off, the air conditioner without the drying and mildew prevention function will immediately stop, so that the internal moisture will remain If it exists, mold will be produced in the long run, and the musty smell will naturally occur.

Reason 3: The air conditioner that has not been used for a long time will also produce peculiar smell when it is started, because the condensed water accumulated in the heat exchange coil, fins and their surrounding parts will slowly evaporate, forming a suitable high temperature condition for use. to multiply microorganisms around the coil. The large amount of gas produced during the breeding process will be released under the drive of the air conditioning system and become a source of odor.

Reason 4: Some non-efficient filtration systems at the end of the air supply, such as computer rooms, hotel rooms, etc., although the interior decoration is good, the fresh air and air conditioning air supply are filtered, but some indoor air supply openings and windowsill surfaces Can still be found near dust accumulations. A layer of dust also adheres to the surfaces of the internal parts. It is believed that the large amount of dust brought by the fresh air and accumulated in these places not only carries microorganisms, but also provides indispensable nutrient conditions for the reproduction of microorganisms, causing the air conditioner to produce odors.

Reason 5: If you often smoke, spray perfume, make up, etc. in the air-conditioned room, the air conditioner in the room will pass through the air conditioner evaporator (indoor unit) for a long time and be adsorbed on the evaporator or filter. After a long time, there will be a strange smell when the air conditioner is turned on, so the air conditioner room should be kept clean.

How to remove air conditioner odor:

Method 1: Whether it is used frequently or occasionally, clean the air conditioner regularly. You can buy specialized air conditioner cleaners. Open the inner shell, remove the filter, you can see the evaporator with metal fins, and spray evenly into the evaporator when the power is off. After waiting for 15 minutes, turn on the air conditioner, the dirt will flow away with the condensed water, and it is easy to remove the odor.

Method 2: In the process of cleaning the air conditioner, it is not enough to just clean the filter screen, because the filter screen only filters part of the dust, and a lot of dust, mites, pollen and mold will accumulate through the filter screen to dissipate heat a! and accumulated a large number of germs. Cleaning and disinfection of heat sinks is key. When cleaning air conditioners, we can do one more step at a time. While cleaning the filter screen, the air conditioner radiator is also cleaned and disinfected, so as to effectively prevent the bacterial growth of the radiator from polluting the indoor air and truly remove the odor.

Method 3: Air conditioners should be disinfected once a month. When the season changes every year, the air conditioner should be thoroughly cleaned and disinfected before it is turned on for the first time. However, during the months when air conditioners are used more frequently, such as summer, people may stay in air-conditioned rooms for a long time. Air quality directly affects our health, so air conditioners need to be cleaned regularly.

While air conditioners provide a convenient and comfortable environment for our lives, we also need to be diligent in maintaining air conditioners to prolong their service life. After cleaning the air conditioner, you no longer have to worry about smelling bad. We enjoy cool and comfortable air in summer.
