Advanced air distribution technologies for enhanced cleanliness and energy savings in operating rooms

This study investigates the impact of advanced airflow distribution technologies on the cleanliness and energy efficiency of operating rooms. A compound laminar airflow ceiling (CLAC) was developed and evaluated using computational fluid dynamics (CFD) simulations, experimental measurements, and field tests. Results show that the CLAC significantly reduces air circulation zones and solid aerosol particle concentrations in critical surgical areas compared to standard laminar airflow ceilings. The findings also reveal that the enhanced air distribution allows for lower airflow rates while maintaining or exceeding cleanliness standards, enabling potential operational cost savings of up to 40 %.
