Bactericidal effect of intense pulsed light dynamic air sterilization device

Investigates the bactericidal effect of the sterilization device in the standard test chamber and the duct, as well as the influencing factors of the sterilization efficiency, by the experimental method. The results show that in the standard test chamber, the sterilization efficiency on the white staphylococcus is up to 99.52% when the sterilization device runs 20 minutes. And when other factors are constant, the sterilization efficiency of the sterilization device in the duct decreases with the increase of velocity and the air relative humidity in duct, and the smaller the microbial particles size, the higher the sterilization efficiency is. The application effect of the sterilization device used in an office shows that when the air change rate is 10 h^-1, the microbial concentration tends to be stable by the sterilization device working 50 minutes, and the bacterial eliminating rate reaches 80.6%.
