Automatic Opening Vents (AOVs)
Automatic Opening Vents (AOVs) can be used in both natural and mechanical smoke ventilation systems. They can be activated to control the ambient temperature and maintain comfort, or to aid with smoke clearance in the event of a fire, to allow a means of escape and access for firefighters. Added convenience can be achieved through automation so that the system reactions to triggers sent from sensors rather than a human response.
What is a SHEV system?
Smoke and Heat Exhaust Ventilation systems are designed to exhaust smoke and heat from a building, providing a safer means of escape for occupants and improved access for firefighters. They are often used in the communal areas of a building where access is key to fighting fire.
When a building is on fire, smoke is the main killer, so the importance of an effective SHEV system should not be underestimated. AOVs are a vital component in the removal of asphyxiating smoke. Removing the smoke and heat also helps reduce the chances of flashover, where building fires significantly accelerate.
Smoke ventilation
The key benefit to AOVs in a SHEV system is the effective exhaustion of asphyxiating smoke. Automatic Opening Vents represent a highly cost-effective means of venting areas to aid smoke clearance, in order to provide means of escape and improve access for firefighting teams.
AOVs are triggered upon the detection of smoke. The smoke sensors throughout the building will relay messages to the smoke control panel. This in turn intelligently triggers the AOV, that will provide efficient ventilation to open while keeping those that could hinder ventilation closed.
What’s more, indoor environments can be drastically improved for occupants by operating automatic openings vents. In environmental systems, AOVs can operate on a smart algorithm to provide comfort when required and improve efficiency. Operating in this manner means at times when increased ventilation is required, the system can trigger the opening of the vents before the environment reaches critical levels.
In light of the above information, there are many uses for AOV systems in smoke ventilation. With that said, what are the AOV products currently available to you?
