　　Central air-conditioning has really caused trouble recently.

　　On May 18th, at a news conference on the prevention and control of the new coronavirus pneumonia epidemic in Beijing, Chen Xin, director of the Xicheng District Health and Health Commission, reported that 33 people had concentrated fever in Xicheng District. Thirty-three patients were clinically diagnosed with bacterial respiratory tract infections, and many were positive in group A hemolytic streptococcus. Combined with the epidemiological investigation, clinical manifestations and laboratory test results, the case of new coronary pneumonia has been ruled out by the expert group. Most patients reported that the fever was related to the recent use of central air conditioning, and the pathogen was initially judged as group A hemolytic streptococcus. The news has once again aroused great concern from people. Central air conditioning will cause trouble. If household air conditioners are not sterilized for a long time, will they have problems once they are started in summer?

　　Gao Qing'e, director of the Department of Infectious Diseases and Director of the Emergency Infection Ward of the Fourth People ’s Hospital of Zibo City, said that long-term air conditioning will inevitably cause bacteria or dust to adhere to it. The wind blown during use will make these substances flow in the air. In such a closed environment, it may cause respiratory diseases.

　　In order to eliminate the concerns of citizens and units in air-conditioning disinfection and sterilization, the newspaper ’s special action on air-conditioning disinfection and sterilization benefiting the people has attracted wide attention. Many citizens call the registration hotline, hoping to disinfect and sterilize the air conditioners in their homes and units as soon as possible. More and more people realize the necessity and urgency of disinfection and sterilization of air conditioners.

　　Since the implementation of the special action of air conditioning, disinfection and sterilization, benefiting the people, it has received great attention and active participation from many schools and residents.

　　As of May 27, hundreds of split air conditioners and central air conditioners in Kairui Primary School and Zibo No. 4 Middle School have completed disinfection and sterilization. Some air conditioners in residents' homes have also been disinfected and sterilized. Air conditioners in other units are also waiting for construction.

　　It is worth noting that the reporter discovered some problems after inspecting several scenes with technical staff. For example, most air conditioners in citizens' homes have not been cleaned deeply since they were installed. At most, they only clean the exterior and filter screen of the indoor unit by themselves. This cannot guarantee the harmless operation of the air conditioner. Especially in the office places where some people are relatively concentrated, although the central air-conditioning filters and the like have been cleaned, there is no real disinfection and sterilization, and there are considerable hidden dangers to health and safety.


　　According to professionals, the ventilation ducts, air outlets and filters of the central air conditioner and the evaporator, fan blades and filters of the household split air conditioner are wet, will attract dust, smoke, and easily breed bacteria, mold, and spread viruses, causing users to cross. Infection, so air conditioning cleaning and disinfection is very necessary. Living under uncleaned air conditioners for a long time, it is very easy to be infected with respiratory diseases, legionellosis, allergies, asthma, allergic pneumonia syndrome, unhealthy building syndrome, office disease, etc., among which legionellosis is in North America, Europe, Asia, It has happened in some African countries (including China), with a mortality rate of up to 15%. During the epidemic prevention and control period, disinfection and sterilization of the air conditioning system is particularly important and urgent to protect people's health and safety.
