When you enter a mall, office, or classroom, the air is usually clean and comfortable. That’s not magic, but rather the HVAC system doing its job. An important part of it is fresh air in all those premises, particularly those using the VAV system, which is the Variable Air Volume system.
Now, calculating fresh air for a VAV system may sound super complicated, but really, it’s a lot simpler once you break it down. So, let’s do this step by step.
What Is a VAV System?
With a VAV system, the quantity of air supplied to each room is varied.
Instead of always blowing the same amount of air everywhere, it varies the airflow according to the room’s needs. This helps to conserve energy and keep people more comfortable.
