Causes of air conditioning odor
Reason 1. After the air conditioner has been used for many years, a certain amount of dust will be squeezed inside the indoor filter screen and copper sheet, which will produce a certain peculiar smell after accumulating a certain amount. As the air conditioner is turned on, the peculiar smell of the air outlet of the air conditioner will float into the air.
Reason 2. After the air conditioner is cooled hot, in many cases, there will be moisture in the interior of the indoor unit. Therefore, when the air conditioner is turned off, the air conditioner without drying and mildew prevention function will stop immediately. In this way, the internal moisture will always exist, mold will be produced in the long run, and the mildew smell will naturally occur.
Reason 3. The system does not operate for a long time, and the fins of the heat exchanger are nearly blocked.
Reason 4. Some non high efficiency filter systems at the air supply end, such as computer room and hotel room, although the indoor 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 windowsill, and a layer of dust is also adhered to the surface of internal components.
Reason 5. After the air conditioning system is started, the indoor bacterial concentration and odor increase instead. This is because the condensate trapped on the heat exchange coil, rib and its surrounding components evaporates slowly, forming a high humidity (and high temperature) condition around the coil, which becomes an environment suitable for microbial reproduction. A large amount of gas generated during reproduction is suddenly released due to the drive of the system, Become the source of stench. It is believed that a large amount of dust brought by fresh air and accumulated in these places not only carries microorganisms, but also provides indispensable nutritional conditions for microbial reproduction.
