Common disinfection methods of central air conditioning

Central air conditioning is a brand-new air treatment system, which is widely used in public places, commercial office buildings, hotels and many other places. However, after the central air conditioning system is used for a period of time, due to long-term recycling and long-term non-cleaning and disinfection, it is easy to produce problems such as bacteria, viruses, dust, odor and mold. In order to ensure indoor environmental sanitation and reduce cross-infection, it is necessary to carry out air conditioning disinfection regularly.

Here are several disinfection methods of central air conditioning:

1, chemical disinfection method: use chemical drugs with sterilization ability to disinfect the air conditioner, such as peracetic acid, chlorine-containing impregnating solution, ultraviolet purifier, etc.

2. Gas disinfection: the air conditioning system is injected with appropriate amount of chlorine, ozone and other gases to achieve the purpose of killing bacteria and viruses.

3. Physical disinfection method: air and surface are disinfected by physical means such as ultrasonic wave, high-pressure steam, high-frequency vibration and electron beam.

The above are three commonly used disinfection methods for central air conditioning at present. Before disinfection operation, the disinfection scheme should be determined first, and appropriate drugs and tools should be selected for disinfection. In the process of disinfection, we should cooperate with the system occupants and strictly implement the operation and safety regulations to ensure safe operation and avoid secondary pollution. After regular disinfection and cleaning, the central air conditioner can maintain the effect of fresh air, let people breathe fresh and healthy air, and avoid human health being affected.
