Abstract EN
It is known that indoor air quality has a great impact on health and behavior and therefore becomes an economic issue regarding especially health cost and productivity.
The traditional approach to create good indoor air quality involves removing pollution load and addressing thermal comfort by means of standards.
The indoor air is perceived as positive or negative depending on whether the room occupants feel that air is artificial or whether they accept the air as natural, most by a perception of artificial indoor air.
As discussed from the previous work [5] "the efficiency of the ventilation systems depends, in turn, on the location of the supply outlets and extraction ports".
Most mechanical engineers face the common problem" where can we locate the supply outlets and extraction ports and what is the proper direction of the airflow inside the space".
To overcome the problem of ineffective ventilation, guidelines of proper location selection of the supply outlets and extraction intakes should be established.
Ventilation accordance with ASHRAE standards [1], ventilation for acceptable indoor air quality (AIAQ) should be used for areas where specific standards are not given.
Design of a ventilation system must as much as possible, provide air movement from clean to less clean areas.
Building an effective ventilation system to achieve the optimum-hygiene conditions needs more careful and collaborative work.
Making indoor air quality (IAQ) a top priority in the healthcare facilities starts with the building design [7].
The air flow patterns are a very important factor in obtaining good indoor air quality.
This paper discuses an experimental and theoretical study of test room models to investigate the most suitable and effective location of the supply and return grills for better air flow distribution inside the conditioned space.
