Optimization of air distribution patterns by arrangements of air inlets and outlets: case study ...

In this research, possible methods to improve the air distribution pattes of an operating room (OR) employing CFD method were investigated. Laminar airflow (LAF), turbulent airflow (TAF), and LAF with the air curtain were examined. It was found that LAF and LAF with the air curtain cases were superior to TAF-based cases. The study showed that the LAF and LAF with the air curtain cases as the proposed configurations have an acceptable capability to maintain the indoor air conditions within the range recommended by the standards. According to the simulations, the LAF with the air curtain case is the most suitable case in terms of the contamination risk, and it was recommended to be implemented in the existing OR.
