Electric Dampers: Reducing Risks and Saving You Money
Electric dampers are a money wise addition to your home or office HVAC system where tight control of the heating and cooling environments can save you lots of money on energy costs. These dampers can accurately control the amount of air that is allowed to flow in or out of a ventilation system by either completely closing off the passage of air or carefully moderating airflow by initializing an actuator to partially open or close the damper as the need may be.
For example, in a low traffic area of the home or office, electric dampers function to restrict airflow to the rooms uncommonly used during the day, such as bedrooms or storage areas. By contrast, electric dampers can be utilized in high-traffic rooms to maximize the energy savings of the system by partially opening or closing the damper as dictated by the system thermostat, preventing high energy usage and high end-of-the-month costs to the user.
Electronic dampers come in two types that are appropriate in various settings. The first type is controlled by two actuators, one which controls the opening of the damper, and the other which controls the closing of the damper. This design allows precise airflow control through the system and can help prevent damage due to blockages and power failures, where a blockage in the ventilation system due to a faulty or wrongly triggered damper could damage the HVAC hardware.
The second type of electronic dampers come spring-loaded for open or closed positions. In other words, the dampers are operated by only one actuator instead of two, and are spring loaded to either open or close in the absence of electricity. This type of damper is ideal when you want to control your fail-safe protocols, such as in the event of a fire: if the electric dampers in your system are designed to shut in the absence of electricity, then smoke will be prevented from passing to other areas of the structure during a fire.
It is important to consider the elements of your design when choosing which types of electronic dampers to use in your home or office ventilation system. Specifically speaking, a spring-loaded actuator that is designed to close in the absence of electricity would be ideal in a low-traffic area of the structure, such as a bedroom, storage area, or garage. This way, no power is required to keep the damper closed, reducing the amount of energy that your system consumes. On the other hand, electric dampers that can precisely control the amount of air passing through your vents can be desirable in high-traffic areas of the structure, or in areas that require strict environmental control, such as a laboratory.
Each of these considerations bears attention when deciding whether or not electric dampers should be utilized in your system. By choosing the right combination of actuators and dampers for your HVAC vents, you can strictly control the energy usage and expenditures that you must make to keep your family in comfort.
