According to a survey conducted by the School of Public Health of Fudan University in Shanghai, the fin evaporator behind the household air conditioner filter is a source of bacterial contamination in air conditioners. The detection rate of bacteria is up to 91259/cm2, and the rate of mold over-standard is as high as 84%.


The temperature and humidity of the fin evaporator of the air conditioner are suitable, and the indoor ventilation in the winter is small, so it is easy to become a hotbed for the growth of germs. Molds in air conditioners may spread through the air, invading human skin, respiratory system, etc., while Escherichia coli, Staphylococcus aureus, etc. may cause digestive diseases such as diarrhea.


Therefore, experts recommend disinfecting the filter and fin evaporator with air-conditioning special cleaning agent before using warm air conditioning in winter. During use, disinfect once every other month. When the use of the warm air conditioner is stopped, it is necessary to disinfect again, so that it can better prevent the breeding of indoor air by germs.


In addition to thorough disinfection, it is important to maintain the flow of indoor air. In winter, although the outdoor temperature is low, ventilation is required twice a day. The better ventilation time is from 9:00 am to 11:00 am, and from 2:00 pm to 4:00 pm, the outdoor temperature is high during these two time periods, so it will not make people feel too cold, and they can avoid the fumes. The peak of the meal. Ventilation in a one-way room is not less than 20 minutes each time, and the room with convection air is ventilated for 10 minutes.
