China’s health administrative departments have inspected the cleaning and disinfection of central air conditioning system.  The results find that there have persons in charge to be responsible for the management, cleaning and maintenance of ventilation system in the public buildings.  Most of fresh air vents are in the reasonable places equipped with filters, emergency shutdown, regional operating and cleaning windows, as well as the regular components cleaning of filters, cooling towers and air handling units and recording reports.

The cleaning and disinfection of central air conditioning system in public buildings is seen as a kind of hard work, with high cost and complex technologies.  Serious pollution on ventilation and water systems will increase the air conditioning load and power consumption, as well as the spread risk of respiratory infectious diseases and other diseases.  Meanwhile, central air conditioning system cleaning work needs special technology which should be certified by national occupation qualification.

China will promote the training of central air conditioning system cleaning to normalize and enhance the technicians’ acknowledge and operational level.  The first training course will be in March.
