Numerical Studies on Heat Ventilation Air Conditioning (HVAC) System in Operation Theaters: a Review

The current review compiles and analyzes the literature on Computational Fluid Dynamics (CFD) studies related to Heat Ventilation and Air conditioning (HVAC) in Operation Theaters (OT). The paper describes the various types of ventilation systems, used in Operation Room (OR) to maintain the Indoor Air Quality (IAQ). The numerical studies show the effect of the HVAC system in contamination dispersion, temperature distribution and airflow patterns. Numerous researchers have worked considering various aspects such as the thermal comfort of the patient and staff, effect of heat due to lighting equipment and the resultant effect on the contamination flow pattern. The most common issue reported throughout the literature being, the contamination sources and their flow behavior.
