Do you want to know how many air changes per hour your building is getting? This article will show you how! Air changes are essential for many reasons, but it can be challenging to determine how often they occur. Luckily, there are a few simple ways to check your AFC count yourself and save money on the HVAC system! Here are three tips for checking how many air changes happen in an hour:
- Use a stopwatch or timer. You’ll need this to see how long it takes from one change of the air until another happens because these events happen too quickly (usually about 15 minutes).
- Check outside windows if they’re open. If they’re closed, compare how much time has passed until the next time you feel a breeze or how much longer it takes for your skin to feel dry.
- Draw a square on paper (or use graph paper) and draw how many minutes an hour is (60). The number of courts that have changed since one air change will give you your answer!
I hope these tips helped you with how to check AFC count.
