| Abstract |
This study examines how air supply and exhaust configurations in air purifiers affect indoor air purification performance and proposes an
optimized design to improve efficiency under the same airflow conditions. Various commercially available air purifier models were analyzed,
and computational fluid dynamics (CFD) simulations were used to assess airflow patterns and purification effectiveness. Findings show that
the arrangement of air inlets and outlets significantly influences air movement and particle removal. Compared to the common design that
draws air from the top and releases it on all four sides, the tower-type model, with both air intake and exhaust located at the front,
distributed air more evenly and achieved better purification. The proposed model improved air cleaning efficiency by up to 32.59% compared
to existing models, indicating potential for enhanced indoor air quality. These results provide valuable insights for improving air purifier
design through better placement of air supply and exhaust components. Future research will explore the system's performance in different
indoor environments. |
