ELI5: Explain Like I'm 5

Airflow

Airflow is the movement of air around a place, like when the wind blows. Airflow can happen inside our homes, offices, or even outside.

Think about when you blow air from your mouth or fan air with a paper fan. You create airflow. Air can move fast or slow depending on how much force you use to create it.

In buildings, airflow is important because it helps keep us cool in hot weather and warm in cold weather. You know how sometimes you feel a draft of cold or hot air? That's because of airflow.

When we turn on an air conditioner or a fan, it creates airflow – cold air is pushed out of the air conditioner or fan and moves around the room. The same thing happens with a heater.

Sometimes, you might hear people talking about air quality. Good airflow helps us have good air quality because it moves stale air (which can have dust or other particles in it) out and brings in fresh air from outside.

In a nutshell, airflow is simply the movement of air from one place to another, and it can help keep us comfortable and healthy.
