Barometric relief

The barometric relief allows to minimize overpressure in the building caused by the introduction of fresh air. This option is typically installed when fresh air intake is below 25% of the nominal air flow and when the return air pressure drop is below 25Pa.

This option includes exhaust hoods and gravity dampers located in the return air section (Figure 22). When the pressure of the building increase, the gravity dampers open and relieve air to the outside.

If the return air duct pressure drop is higher than the building overpressure, the gravity dampers will not open.

If the return air duct pressure drop is lower than the building overpressure, the gravity dampers will open and releive air outside of the building.
