Volume Control Dampers

While HVAC dampers play a role in controlling the temperature, humidity and freshness of the air in the house and the flow coming from the outside, volume control dampers are meant to manipulate the flow of air inside the house.

Volume control dampers are often part of the larger heating and cooling assembly in homes, and may also be referred to as zone dampers.

Electric Variants

Electric volume control dampers usually work on a motor. One of the types of designs is based on a synchronous motor, which is connected to a rotary switch.

This switch can control the connection of the motor when the damper is either open or closed. In other words, when the damper is open, the motor works accepts current until it closes, and vice versa.

This motor usually derives power from the source used for the rest of the system, which allows for them to be used with low-voltage thermostats and wiring.

To prevent the closing of all the dampers in the system at the same time, which can damage the furnace, the construction of this type of damper limits the blockage of the flow of air along the full passage of the duct.

Spring Return

The other electric variety makes use of a spring and a motor. Opening the motor relies on the spring mechanism, but closed by the power from the motor. The exact specifications of this however, depend on which one of the precautions is being taken.

When the failsafe is for the damper to be open, the absence of power allows it to open and for air to flow.

On the other hand, the failsafe for the damper is closed when power has failed and smoke and fire have to be prevented from spreading.

It is also possible for the dampers to be closed along the route in such a way that they do not cause the absolute blockage of the passage of air, and retain minimal flow.

Divisions

To beef up efficiency, a volume control damper in dubai - PrimeAirCon can be made of more than one smaller segment, which usually serves the areas in the house that need the air control most during the times of the day.

For instance, the ground floor of a house may be catered to during the day, while the occupied rooms may be served at night. In dampers that control the volume of air to provide heating, this will allow the unused parts of the assembly time to cool.
