Over the next 150 years Londinium developed into a centre for trade and business, and also the administrative centre for the Roman-occupied areas in the rest of England. The new city included buildings like a basilica, an ampitheatre, temples to gods such as Mithas (a Persian deity), a forum and the Governorâs Palace.
AOV is simply an abreviation for Automatic Opening Vent. An AOV system is a control system designed to vent air or smoke for use in natural & smoke ventilation.
AOV control systems are used mainly to control the ventilation of smoke in a fire. Changes to building regulations were made due to the results of investigations into smoke inhalation. When a detector or call point is triggered an AOV control system will open actuators, windows or vents to create ventilation. This clears smoke for people leaving the building and vents smoke out of the area that has been triggered.
