Abstract

ABSTRACT
Surgical operating room needs an efficient ventilation system to achieve thermal
comfort and clean environment. This paper aims to improve the air distribution in the
operating rooms with two operating tables configuration. Six test cases with different
numbers, sizes and locations of exhaust air grills have been simulated using CFD
and validated with experimental measurements. The air diffusion performance index
(ADPI) value has been estimated for each case. The results show that the case with
eight exhaust air grills distributed in the four corners of the operating room gives the
highest ADPI (63.06%).
