Automatic Dampers Functions and Usages in Heating, Ventilation, and Air Conditioning
Automatic dampers have a variety of functions and different applications. The one thing that automatic dampers all have in common is that they control the flow of some sort of air or gas. By utilizing automatic dampers you can automatically control when the damper opens or shuts based upon predetermined user settings.
Utilizing automatic dampers can help you save money when it comes to your electricity bill. Dampers make airflow more efficient by controlling airflow into different areas of a building or house called "zones".
By using automatic dampers you can make sure the electricity or heating you are using to power your air flow it being used to its full potential. Automatic dampers most commonly come in flue dampers, zone dampers, and fire dampers. Automatic dampers prices' vary depending on their intended use, the materials they are composed of, and the size of them.
Automatic dampers are used in Heating, Ventilation, and Air Conditioning (HVAC) ducts, boiler and furnaces, and fire dampers which will shut off the flow of oxygen to a room when it reaches a specific temperature indicative of a fire.
Automatic dampers are controlled by damper actuators. Damper actuators are powered by a motor and control the plates inside the damper known as blades. Damper actuators; when they either open or close the blades; control the flow of smoke, air, and other gases.
The two basic types of damper actuators that are used in automatic dampers are electric damper actuators and pneumatic damper actuators. Electric damper actuators are commonly available with features known as thermal protection, reverse and direction action, or an economical low power supply feature.
Pneumatic actuators in automatic dampers have an original position that they start in with a setting related to the pounds of pressure exerted on the blades. How much the blades open or close in a pneumatic damper actuator is directly related to the feedback spring. The spring is designed to either open or shut the damper depending upon the psi exerted on the automatic dampers' plate.
The most common application of automatic dampers is the control of airflow into specific regions in an HVAC system in a house or building. Think of shutting the vent in a room you don't want to air condition in your house. Automatic dampers work the exact same way but whenever a certain pre-specified temperature is reached the automatic dampers will either open or close to control the air flow in that particular room or zone.
This application is especially useful for home owners in regions where it becomes extremely hot or cold during certain seasons. Whenever you are at work or away from the house if you have HVAC duct automatic dampers set up you can control for it to shut down the airflow to particular rooms.
No one wants to walk into an uncomfortably hot or cold house whenever they return home from work during seasons of extreme weather. There is no reason to heat or cool your upstairs bedroom though during the middle of the day if you are not even there. Automatic duct dampers can allow you to specify what certain rooms will be maintained at certain temperatures while shutting off airflow to others. This airflow can be set to be turned back on at a specific period of time as well so if you work late, your bedroom will be heated 30 minutes before you return home.
