If you picture an HVAC system with a main supply line and supply ducts running from it to different physical areas (floors, rooms, etc.) then it’s easy to grasp that if you place dampers at intersections, you’re essentially “zoning” your system. The dampers serve to direct, or re-direct air to one location or zone or another.
The function of a damper is to regulate the amount of air (cooled or heated) that enters the ducts for dispersal around a building ultimately ensuring the temperature in a destination zone reaches the desired level, which may differ from the desired temperature in another area.
There’s a distinction to be made here between dampers and vents, which don’t serve the same function. Dampers re-direct air flow in a different direction. Vents, when closed, simply shut off air from reaching its destination.
Like vents, dampers don’t come in “one size fits all”. There are different kinds of dampers and different types of control mechanisms for them. Let’s look at the alternatives, first control mechanisms, of which there two options.
When it comes to the dampers themselves, alternatives include:
Now that we understand dampers, what they are and what they do, one big question remains. What are the benefits they deliver? Here are five that spring quickly to mind.
Generally, the larger facility and the more distinct zones it contains the more likely it is that dampers will make a significant difference. For instance, with dampers you can more easily achieve the desired, but different temperatures required by an office space on one floor and a warehouse area on another.
Dampers can ensure that conditioned area only is fed to the areas that need it, and that conditioned air isn’t wasted on spaces where it is not needed, such as an empty office or a room that is already comfortable.
Dampers contribute to creating a healthy environment by ensuring consistent air circulation and regulated temperatures where needed.
As we noted earlier when discussing types of dampers, some can help significantly reduced HVAC system noise and this, too, improves the facility’s environment.
Dampers perform the function of sealing ductwork, the knock-on effect of which is to reduce or entirely prevent air leaks thus eliminating the chance of already conditioned air escaping. This, of course, improves the performance of the HVAC system generally while also upgrading energy efficiency.
