The influences of air change rates and particle generation on indoor particulate concentrations in a cleanroom were studied by eight numerical simulation cases. Results show that the influence of ACH on indoor particulate concentration is very significant than that of particle generated concentration when ACH great than 4.0 h-1. And ACH = 4.0 h-1 seems a suitable value for central air conditioning (AC) systems in residential buildings and public buildings.
