4hw.com.cn: when we use the air conditioner in summer, every time we just turn on the air, there will be a peculiar smell. After the air conditioner is used for a long time, it may smell a peculiar smell when the air conditioner is refrigerated, which indicates that the air conditioner may not be very clean inside. Do you know what causes this?
How to deal with the peculiar smell of the air conditioner
Causes of peculiar smell in air conditioning and refrigeration
1. After the air conditioner is used for a long time, there will be a lot of dust in the filter screen and copper strip. If the dust accumulates to a certain amount, it will produce peculiar smell. When the air conditioner is turned on, the peculiar smell in the air conditioner will blow into the air with the wind.
2. After the air conditioner is cooled and heated, there will be more moisture in the interior of the indoor unit. When the air conditioner is turned off, the air conditioner will be turned off without timely drying and mildew prevention. As a result, the moisture in the air conditioner always exists. Mould will be produced after a long time, and the mildew will be emitted when the air conditioner is turned on.
3. There are foreign matters in the air conditioner cabinet. Due to the large space in the cabinet air conditioner, some mice and cockroaches will cause pollution after entering. It may be that cockroach eggs and some cockroach bodies are inside.
4. It is also possible that the old refrigerant and compressor oil of the air conditioner leaks. After starting, the internal and external units can operate. The air outlet is windy, but it has a strong odor. However, if the air conditioner is not refrigerated, the sound of gas leakage can be heard. This should be that the air conditioner cooler leaks and mixes with the compressor oil to produce a mixed odor.
5. The new air conditioner may smell of plastic or medicine. The smell of plastic is caused by the frequent expansion and contraction of plastic parts in the new air conditioner, while the smell of liquid medicine is from the anti-oxidation liquid medicine coated on the hydrophilic aluminum foil of the evaporator
6. Some air supply terminals are not high-efficiency filter systems, such as computer rooms and hotel rooms. Although the interior decoration is good and the fresh air and air conditioning air supply are filtered, dust can still be found near the air supply outlets and on the windowsill surface. There is also a layer of dust on the surface of the internal parts of the machine. When the air conditioner is blowing, the dust will be dispersed.
7. After the air conditioning is started, the condensed water on the heat exchange coil, fins and their surrounding parts will slowly evaporate to form a high humidity (and high temperature) condition around the coil, and become an environment suitable for microbial propagation. A large amount of gas generated during propagation is suddenly released due to the system drive, which becomes the source of odor.
How to deal with the peculiar smell of air conditioning and refrigeration
1. Spray some metal cleaner on the indoor evaporator.
2. Clean the air conditioner regularly
(1) While cleaning the filter screen, clean the cooling fins of the air conditioner, preferably disinfect them, so as to prevent the growth of bacteria in the cooling fins and avoid indoor air pollution.
(2) It's better to disinfect once a month. The radiator of air conditioner can't be disassembled. Because of the particularity of its mechanism, it can't be effectively cleaned only by wiping with a wet cloth or cleaning with a brush, and it may also damage the radiator. The normal air conditioner disinfectant should be used to disinfect the air conditioner fins. Remove the dirt and germs on the heat sink, the cooling effect of the air conditioner will be better, and there will be no foul smell.
