The air conditioner in the elevator will smell as soon as the cold air is turned on, what s going on

Reason 1: After the air conditioner is used for many years, 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 conditioning outlet odor will drift into the air.

Reason 2, because the air conditioner in the refrigeration heat, 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.

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

Reason 4: 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 conditioning air supply are filtered, dust can still be found near some indoor air supply outlets and on the surface of the window sill, and a layer of dust is also adhered to the surface of the internal parts of the machine.

Reason 5: After the air conditioning system is started, the concentration and odor of indoor bacteria increase, which is due to the slow evaporation of the condensate retained on the heat exchange coil, ribs and their surrounding parts to form a high humidity (and high temperature) condition 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. It is believed that the large amount of dust brought by the fresh wind and accumulated in these places not only carries microorganisms, but also provides indispensable nutrients for microorganisms to multiply.

Solution. Do 1 more step at a time.

Cleaning the filter is not enough Radiator cleaning and disinfection is the key At present, there are still most households that usually only stay at the filter level for cleaning the air conditioner, in fact, this can not completely remove the pollution caused by the air conditioner. Because the filter only filters a part of the dust, some dust will still accumulate on the heat sink through the filter and accumulate a large number of germs. After understanding the real cause of air conditioning pollution, we can do one more step at a time to clean the air conditioner, clean the filter screen and clean and disinfect the air conditioner radiator, so as to effectively inhibit the bacterial breeding of the radiator and bring pollution to the indoor air.

Disinfect 1 time per month.

Clean and disinfect the air conditioner radiator every month In addition to developing the habit of cleaning and disinfecting the air conditioner in 1 more than 1 step each time, it is also necessary to clean and disinfect the air conditioner radiator regularly. Every year, the air conditioner should be thoroughly cleaned and disinfected before the first turn on during the seasonal season, but in the months when the air conditioner is frequently used, such as summer, because people may stay in the air-conditioned room for a long time, the indoor air quality directly affects our health, so the air conditioner needs to be cleaned regularly. The easy way to do this is to disinfect the air conditioner once a month.

The elevator shaft is a nearly confined space, and the operation of the mechanical system and the lubrication system will produce a very strong odor, which is what you call the smell of iron.

However, who will install air conditioning in the elevator, usually the shaft can be solved by using the chimney effect, the car and the ventilation fan.

That's because it hasn't been maintained for a long time, and it needs to be ventilated and cleaned frequently.

After a long time, it needs to be cleaned, and it has nothing to do with Freon, as long as the effect is good!

If it is a new elevator, it will smell plastic, and the old elevator will be dirty if it smells!!

Air conditioning winds can blow out odors, which are generally caused by the following reasons:

The system ran for a long time, and the heat exchanger fin was full of dust, causing clogging;

It is caused by dust adhesion to the surface of the air supply outlet and internal parts of the indoor unit, which is difficult to avoid even in special environments such as computer rooms and hotel rooms where the air is filtered.

The large amount of dust brought by the fresh air and accumulated in these places not only carries microorganisms, but also provides indispensable nutritional conditions for microorganisms to multiply.

The smell of the air conditioner that has not been used for a long time will be very strong when it is started, which is due to the slow evaporation of the condensate retained on the heat exchange coil, fins and their surrounding parts, forming a high temperature condition suitable for microbial reproduction around the coil, and a large amount of gas generated by microbial reproduction will be released under the drive of the air conditioning system, becoming the source of foul odor.

Solution: Small household air conditioners use air as the cooling medium, and the odor of air conditioners is mainly caused by dirt, dust, oil stains, mildew, microbial germs, etc. attached to the air-cooled condenser of the outdoor unit, the evaporator fins and filter screens of the indoor unit. Ordinary users can generally only clean the filter regularly, and other parts of the machine are more suitable to find manufacturers and professionals, who will use professional tools and cleaning liquids to "clean" the air conditioner.

The peculiar smell is caused by poor ventilation of the indoor unit, dust and mildew in the condenser and dust filter. Check whether the fan of the internal unit is running normally, and clean the dust filter and the indoor unit. The lack of water discharge may be caused by the lack of freon, which is manifested as poor cooling capacity, not cold, and freon can be added to make the air conditioner work normally.

You open the air conditioner cover and see if the blades are dusty, and then you see if the air conditioning cover on the outside is still covered, and if it doesn't work, you can ask the maintenance staff to take a look

You have to see if the air filter is clean, if there is too much dust on it, take off the filter and clean it again.

The problem is generally that there is not enough refrigerant.

After many years of use, the general household air conditioner will smell a smell similar to mold when it is turned on, and some friends are difficult to get rid of even if they often clean the filter of the air conditioner for two or three weeks.

Air conditioning winds can blow out odors, which are generally caused by the following reasons:

First, the system has been running for a long time, and dust accumulates between the fins of the heat exchanger, causing blockage;

The second is caused by the adhesion of dust on the surface of the air supply outlet and the internal parts of the indoor unit, which is difficult to avoid even in special environments such as computer rooms and hotel rooms where the air has been filtered;

Third, the large amount of dust brought by the fresh air and accumulated in these places not only carries microorganisms, but also provides indispensable nutritional conditions for the reproduction of microorganisms;

Fourth, the air conditioner that has not been used for a long time will have a strong smell when it is started, which is due to the slow evaporation of the condensate retained on the heat exchange coil, fins and their peripheral parts, forming a high temperature condition suitable for microbial reproduction around the coil, and a large amount of gas generated by microbial reproduction will be released under the drive of the air conditioning system and become the source of foul odor.
