Positive pressure air outlet actuator

Definition and function

The positive pressure air outlet actuator is an electromechanical device used in building air conditioning systems, mainly used to control the opening and closing of air outlets. It uses a built-in motor and mechanical transmission device to realize the opening and closing operation of the air outlet, thereby controlling the indoor air circulation. This mechanism can adjust the size and angle of the air outlet as needed to meet different air supply requirements.

Working principle

Under normal working conditions, the positive pressure air outlet actuator opens or closes the air outlet through the control of the controller, thereby controlling the indoor air circulation.

The motor in the mechanism rotates the transmission device, thereby driving the opening and closing of the air outlet.

Application scenario

The positive pressure air outlet actuator is suitable for air conditioning systems in various buildings, machine rooms, factories and other places, and is an indispensable part of modern building air conditioning systems.

Fire damper mechanism

Definition and function

The fire damper is a device mainly used in building fire protection systems, which is used to automatically close the air delivery duct when a fire occurs to prevent the spread of fire. It is usually installed in ventilation ducts, flues and air-conditioning systems. Once there is a fire in the duct, the closing device of the fire damper will be triggered, and the air delivery duct will be automatically closed, which will isolate the fire source.

Working principle

The fire damper is controlled to open and close by a thermal element or a control device. When the temperature in the duct reaches the set value (such as 70°C or 280°C), the thermal element will trigger the closing device to quickly close the fire damper.

Fire dampers are usually made of metal or non-combustible materials to ensure that they still have good flame retardant properties at high temperatures.

Application scenarios

Fire dampers are an important part of building fire protection systems and are widely used in ventilation ducts and air-conditioning systems of various buildings to improve the fire safety performance of buildings.

Combination of multi-leaf air outlets with positive pressure air outlet actuators and fire dampers

In practical applications, multi-leaf air outlets, positive pressure air outlet actuators and fire dampers may be used together. For example, in a ventilation and air-conditioning system with fire protection requirements, a multi-leaf air outlet with a fire damper function may be used, and its opening and closing may be controlled by a positive pressure air outlet actuator. This can not only meet the air supply demand, but also automatically close the air supply outlet when a fire occurs to prevent the fire from spreading.

In summary, multi-leaf air supply outlets, positive pressure air supply outlet actuators and fire damper mechanisms each play an important role in the building air conditioning system and building fire protection system. Their collaborative work ensures the effective circulation of indoor air and the fire safety of the building.
