Question:

The air-conditioner filter has been cleaned, still has bad smell, how to handle?

The air-conditioner filter has been cleaned, still has bad smell, how to handle?

Answer:

Reason 1, after they use air conditioning, the indoor mesh and copper internal will squeeze some dust, so after accumulated to a certain amount will produce certain peculiar smell, as the open air conditioning, air conditioning wind smell would waft into the air. Reason 2, because the air conditioning after refrigeration and heat, in many cases, the interior of the indoor machine can have the moisture, so after turn off air conditioning, no dry mouldproof function of the air conditioning will stop immediately, so that the internal moisture, in the long run will produce mold, mildew and naturally.
The system is not running for long, and the heat exchanger is close to full. Reason 4, some supply air terminal hepa filter system, such as computer rooms, hotel rooms, although the interior decoration is good, fresh air, air conditioning air supply all pass filter processing, but some of the indoor air diffuser and window surface can still be found nearby dust, machine also stick a layer of dust on the surface of the internal.
After 5, air-conditioning system startup, indoor concentrations of bacteria and odor but increases, this is due to the heat exchange coil, rib and its surrounding parts stuck on the water slowly evaporates form coil around the high humidity and high temperature conditions, to be suitable for microbial breeding environment, breeding a large amount of gas generated due to the system drive suddenly released, becomes the source of the stench. The vast amount of dust that is thought to have been brought and deposited in these places not only carries microbes, but also provides an indispensable nutrient for microbial reproduction.
