The Balancing Damper Increases Efficiency and Comfort
Properly balancing airflow is essential in setting up a ventilation system in a home or industrial environment. Without this, some rooms will receive too much air and some rooms will not get enough air, causing rooms to be too hot or too cold. The role of the balancing damper is to create a more efficient and comfortable environment, reducing costs to the user as well as providing additional benefits.
Simply using the floor or wall register to regulate the air supply entering a room is not an ideal solution. Registers may completely seal off the airflow, which can cause the branch duct to pressurize or split possibly leading to wasted energy. A balancing damper fits into a duct with a gap around the edges to prevent such pressure from building. Also, the dampers on a floor or wall register may be very noisy. These dampers may also be easily moved when cleaning which can change the rate of airflow. Having proper dampers installed can help prevent these problems.
When the HVAC system is not balanced, it tends to run for a longer period of time as the system tries to adjust to the temperature set by the user. If the duct damper is balanced, proper heating and cooling of each room is achieved. In light of today's rising energy costs, an efficient airflow system is more crucial than ever.
Duct dampers adjust the airflow to each register. When a balancing damper is used, the system is allowed to heat and cool each room properly. Manual balancing dampers can be adjusted from the duct system . They are usually located at duct points and limit the air flow from the main source by sliding open and shut.
The role of the balancing damper is critical in a forced air system since the cooling load drives the size of the duct work. Heating a space usually requires significantly less air than is needed to cool the space. In the winter, however, you may need more heated air because the environment loses heat faster. Factors such as construction and insulation need to also be taken into account.
It is important to evaluate a system on the front end for new construction to ensure efficiency and balance of the airflow. After the fact, it is sometimes not possible to balance a system regardless of the number of dampers or valves that can be installed. Consulting an experienced HVAC expert is crucial when embarking on new construction.
In environments where the duct work may not be easily accessible, a remote balancing damper can be utilized, providing control in balancing airflow at the diffuser or wall plate.
Balancing your HVAC system's airflow creates a more comfortable environment, and will also allow the system to run more efficiently. The more efficiently the system runs, the lower the energy cost to the user. Incorporating the use of a balancing damper will also prevent noisy registers and the possibility of accidental adjustment.
