Among them, 12 units of air-conditioning use of air-conditioning units to send air, the amount of dust on the inner surface of the duct, duct dust on the inner surface of microorganisms, Legionella pneumophila and other qualified rate was significantly improved than before cleaning, statistical differences were statistically significant. Conclusion The centralized air-conditioning and ventilation system in public places can meet the sanitation requirements stipulated by the state after being cleaned and disinfected by a qualified professional cleaning organization in accordance with the “Standard”. To strengthen the regulation of central air conditioning and ventilation systems and industry self-regulation, in order to provide people with comfortable and hygienic and safe living and working environment.
