The damper actuator on Blackhawk supply for example controls the opening and closing as a component of a heating, ventilation, and air conditioning (HVAC) system. The damper can be opened to enable air from outside the building to enter to chill the interior, or it can be closed to keep the inside air contained. Damper actuators are available from manufacturers in both electrical and pneumatic versions. Variations include spring return, rotary, and linear. The type of damper actuator employed is determined by the type and layout of the building’s HVAC system.
A damper actuator aims to enable outside air into an HVAC system or adjust the dampening system to prevent air from entering. It’s possible that an air conditioning system doesn’t need to run at full capacity to chill every room in a building. Using outside air is cost-effective and less taxing on the overall mechanical system if the ambient temperature is acceptable. Air from the system that has been further cooled will enter the structure, and the actuator also can drive warm air out as one of the airs inside cools.
In systems controlled by air pressure, pneumatic damper actuators are used. Spring is usually used to move the actuator, and it is activated by changes in air pressure within the system. Motors, on the other hand, control electric actuators. Other actuators for HVAC dampers include spring-return and non-spring-return actuators, which are often powered by motors.
In some damper actuators gotten on Blackhawk supply for example, a solenoid is included. This aids in the opening and closing the damper by turning available energy into the motion required to complete the task. Stainless steel solenoids, which can withstand corrosive environments, are commonly used in commercial HVAC systems. The actuators can also be mounted in various ways, many of which require the purchase of separate kits. Customers can also have damper actuators customized based on factors like airflow volume.
You should know that all damper actuator works in tandem with other air-conditioning components. Before installing a damper, the type of seals, the number of damper sections, and the air velocity must all be considered. The static operating pressure under normal conditions is also a factor. Figuring the damper torque or damper area can be used to compute these variables. Mathematical formulas assist in determining the appropriate size and kind of actuator.
