And the .pass rates of remaining indicators are all above 80% , while only the pass rate of total number of β - hemolytic streptococcus in blow - in air is 100%. Therefore, a certain degree of pollution exists in the centralized air conditioning system. Conclusion Contamination in central air conditioning ventilation system is not optimistic.＇ Daily health management, cleaning and disinfection of air - conditioning should be done well, ensuring indoor air quality in the operation of air - conditioning system.
