1. At present, the commonly used air disinfection methods in kindergartens mainly include ventilation, physical filtration, chemical disinfection and ultraviolet irradiation. Ventilation is the first choice for air disinfection and purification, which is not only simple, but also safe and effective. The traditional way is to promote indoor air circulation and reduce indoor germs mainly through window ventilation. Now kindergartens and nurseries are gradually installing fresh air systems, mainly because the air quality in many cities is not very good. In autumn and winter, classes must be suspended when the smog is serious. When the air quality outside is poor, it is self-evident that when the windows are opened, various pollutants such as dust, PM2.5 and waste gas will enter the classrooms and rooms. Air disinfection in kindergarten.
2. Kindergarten air disinfection and purification equipment: air purifier. The air purifier can adsorb, decompose or transform various air pollutants, including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria and allergens. , can improve air cleanliness. The air purifier is used in a closed space to purify the original indoor air circularly. Air purifiers can take away bacteria and viruses in the air, but they can't destroy these microorganisms. In this way, the filter screen of the air purifier will become a hotbed of microbial reproduction and easily become a secondary pollution source.
Air disinfection machine. Air disinfection machine is a machine that disinfects air through the principles of filtration, purification and sterilization. In addition to killing bacteria, viruses, molds, spores, etc. Some models can also remove organic pollutants such as formaldehyde and phenol in indoor air. Air disinfection machine and air purifier are products with similar functions, and air disinfection machine can be regarded as an advanced version of air purifier. When using air disinfection machine, whether static disinfection or dynamic continuous disinfection, doors and windows are required to be closed. It should be noted that the expression of "air disinfection machine" does not explain the disinfection principle. So you need to look at the product parameters yourself to know whether it is ultraviolet disinfection, ozone disinfection, or what kind of "sterilizer" principle to use.
Because neither the air purifier nor air disinfection machine can deliver fresh air indoors, which easily leads to indoor suffocation and air turbidity, more and more kindergartens choose to install fresh air system with ventilation and purification function as one of the measures of air disinfection in kindergartens to ensure the air quality of kindergartens and protect the health of children.
