文摘
Negative air ions from the ionizer are quenched notably by dynamic air movement. Turbulence reduces the air ionizer's efficacy on deposition of submicron particles. Particles with higher dielectric constant are deposited by air ionizer faster. Polydisperse coagulation of submicron particles enhances the number decay greatly.
