摘要
For the reason of chemical,biological,and radiological (CBR) terrorism attacks and spread of infectious diseases,the security issue of central air conditioning systems aroused the people's serious attention.This paper analyzes the health and security risks caused by the existing central air conditioning systems such as return air,outdoor air intake,indoor humidity and condensation,the routine operation and maintenance.In order to eliminate the risk,and to ensure the systems reliable,operational and performing in the manner designed,countermeasures for safety must be developed.In addition,periodical cleanness and disinfection of the equipment and duct is necessary.If possible,dedicated outdoor air system is a better solution.
