Indoor air quality and comfort are directly related to ventilation and air distribution strategies. The purpose of this article is to examine the research done on airflow distribution systems and the efficiency of ventilation in a protected inhabited zone. This analysis demonstrates that different tasks of the ventilation system, such as removing heat, removing pollutants, supplying fresh air to the breathing zone, and protecting occupants from cross infection, need different measures of effectiveness or efficiency when evaluating ventilation systems. The study also provides a thorough foundation by discussing techniques for monitoring and analyzing ventilation and air distribution. Finally, we undertake a discussion on the utility and advantages of various ventilation systems, providing a roadmap for future research. The findings of the investigation provide a foundation for the potential future use of individualized ventilation.
