Sunrise Air Conditioning specializes in smoke exhaust ports production

In high-rise residential buildings, it is required that:

(1) The smoke exhaust outlets should be installed on the ceiling of the smoke prevention zone or on the wall close to the ceiling, and the horizontal distance from the smoke prevention zone to the farthest point should not exceed 30 meters.

(2) When natural smoke exhaust is used in corridors or rooms, the total area of the exhaust openings should not be less than 2% of the smoke control zone area.

(3) The exhaust vent should be in a closed state at all times, and can be manually opened during a fire or remotely activated by the fire control room or automatically opened in联动 with the alarm system.

(4) Mechanical smoke exhaust outlets and fans should be equipped with interlock devices. When any smoke exhaust outlet is opened, the smoke exhaust fan will automatically activate.

The exhaust outlets are equipped with either automatic or manual opening mechanisms, typically closed on the building's walls or ceiling. They can be activated automatically or by hand when needed to expel the heat and smoke generated by fires. Their primary functions include: reducing the temperature of the smoke at the fire scene, preventing the spread of the fire; and avoiding deaths due to smoke-induced oxygen deficiency among the victims at the fire scene.

Duct smoke outlets can be categorized by different control methods, including plate-type smoke outlets, multi-blade smoke outlets, remotely controlled multi-blade smoke outlets, and multi-blade fire-resistant smoke outlets, among others.

Duct smoke outlets are typically installed in ceilings or walls. They can be manually activated, reset, or remotely opened and reset, and can also be linked to activate the exhaust fan. In the event of a fire, smoke detectors detect the fire and send an alarm signal to the control center. The remote control device at the control center then issues commands to automatically open the valve plate of the smoke outlet.

The multi-leaf smoke exhaust outlets are normally in a closed state. They can be manually opened, reset, or remotely opened and reset, and can also be linked to start the smoke exhaust fans. In the event of a fire, the smoke sensors detect the fire and send an alarm signal to the fire control center. The remote control device at the control center then automatically opens the valve plates of the exhaust outlets.
