VCDs manage the volume of air that flows through ducts, allowing precise control over the distribution of heated or cooled air to different areas or zones within a building. HVAC systems equipped with VCDs are divided into multiple zones.

2024年3月29日 · In HVAC, a motorized fire damper or MFD is a fire-resistance shut-off device that is usually paired with a fire-rated actuator to close completely within a short period of time to prevent fire from spreading from one room to another room. Most MFDs are 2 hours fire-rated.

What is a Volume Control Damper? A volume control damper (VCD) is a device used in HVAC systems to regulate the amount of air that moves through a duct system. It is designed to keep the airflow within a particular range, delivering optimal amounts of air to different parts of the building.

2024年3月13日 · VCD (Volume Control Damper): A VCD is a specific type of damper used within an HVAC system. It regulates the airflow volume through a specific section of ductwork. Unlike a VAV system, a VCD doesn’t necessarily involve temperature sensors or automatic control.

Round throttle valve in galvanized steel for manual use. Housing made of galvanised sheet steel or stainless steel. They push-fit ends are. ACT-H are circular motorised dampers to regulate air flow in duct systems. The damper blade position can be regulated via an analogue / modulating.

2024年3月23日 · In HVAC, VCD stands for Volume Control Damper. It’s a device used to regulate the airflow within the duct system. VCDs are crucial for ensuring proper heating and cooling distribution throughout a building. Here’s a breakdown of VCD functions: Controls Airflow: In HVAC what is VCD?

Volume Control Dampers are mechanical devices installed within the ductwork of HVAC systems. They have movable plates or blades that can open or close to regulate the flow of air through the system. The adjustment of these dampers can be manual or automated, depending on the specific requirements of the HVAC system.

VCD refers to volume control dampers and they are simply control devices installed in the duct systems to regulate air flow. They are created to either increase or decrease the flow of air or halt it, depending on the amount of heat or coolness required in a specific area.

The square/rectangular style VCD is an opposed blade design which provides exceptional control of airflow with little to no turbulence created in the duct work. This design allows the damper to be installed in either direction of airflow.
