Abstract
ABSTRACT
The ventilation system of a hospital operating room is used to provide comfortable
and healthy environment. The healthy environment can be achieved by minimizing
the risk of contamination through filtration and air distribution scheme. This paper
involves numerical study for different ventilation systems studying the effect of air
distribution on bacteria diffusion and the indoor air quality by using (CFD)
techniques. Five different configurations ventilation systems based on Hospital
guidelines standards conditions are applied on a selected model to evaluate the
efficiency of ventilation systems in minimizing the risk of postoperative infection. It is
concluded that the fourth configurations (laminar airflow (LAF) and exhausts from
low level at two sides exhorts) which matching with DIN and ASHRAE Standard is
the most efficient which satisfies the comfort conditions and provides protection
against infection.
