AHU Air Balance

We have created an AHU Air Balance form that allows the user to either open, close, or release all the vav dampers that the AHU is serving.

How to use AHU Air Balance

The user will go in DB Builder app.

Then, once inside the app, the user will select an AHU that serve vavs (vavs that have refs to the AHU) and then go to Tools in the top menu bar. Inside the drop down menu enter the MISC cathegory, there is going to be an option called "AHU Air Balance".

After the option has been selected there is going to be a popup window with required fields to select.

The required fields to select are:

• Open All Vav Dampers 100%: 
• **Close All Vav Dampers 0%:
• Release All Vav Dampers to Auto:

When a field has been selected, the user can hit Apply and the form will then execute the change.

Example:

Opening dampers

In our example, we want to open all the dampers of the vavs that the AHU is serving.

So we select AHU-1 and open the AHU Air Balance tool. Then select to Open all vav dampers to 100%. Below you can kind of see the damper for Vav-01 at 76%.

After we hit apply, you'll get a popup to double check to make sure the AHU is off to not cause too much pressure. Then it'll take us to the folio app to display all the dampers that it changed.

You can also see Vav-01 Damper was commanded to 100% when before it was 76%. The same process goes if you want to close them to 0% or to release them to auto.
