What is the potential outcome of improper admission of fresh air into a room?

Improper admission of fresh air into a room can lead to the creation of stagnant air pockets. This happens when fresh air is introduced in a way that disrupts the natural airflow patterns in the room. If the air enters at an improper angle or too forcefully, it may not circulate effectively. Instead of mixing with the existing air, it can cause certain areas to receive little to no airflow, leading to stagnation. Stagnant air pockets can result in several issues, including discomfort from inadequate ventilation, an increase in indoor pollutants as the air fails to move and disperse properly, and potentially the growth of mold or other allergens. Proper air distribution is crucial in maintaining a healthy indoor environment, and improper admission disrupts that equilibrium.
