What is the use of VCD in HVAC?

What is the use of VCD in HVAC?

A zone damper (also known as a Volume Control Damper or VCD) is a specific type of damper used to control the flow of air in an HVAC heating or cooling system.

Where do I put the volume control damper?

You can always rely on leading volume control damper manufactures like KAD Air Conditioning for high quality with affordable range of products. The Volume control dampers help to adjust the air flow volume to the other parts of this duct system.

What is a VCD in ventilation?

Description. Volume control dampers need not be overly complicated. The only requirements are that they should have a low leakage when closed, not create too much resistance when open and should be easy to operate. For ease of use, HVC Series VCD Volume Control Dampers are unparalleled.

Which actuator is used in HVAC system?

Air Volume Modulating Actuator. Air volume modulating actuators are used for the air volume control damper and the variable air volume (VAV) box in HVAC systems.

What is volume dampers?

A damper in an HVAC system, also known as Duct Damper or Volume Balancing Damper is a movable plate, situated in the ductwork that regulates the flow of air and redirects it to specific places of a house. The usage of dampers is typically seen in zoning or zone control systems.

How does a HVAC actuator work?

The AC actuator moves air distribution doors to two or more positions to direct air flow for heating and A/C vents. The AC actuator is located underneath the dashboard attached to air distribution doors in the hvac box. Once there, the door will stay in that position until the driver moves the function selector again.

Why dampers are used in HVAC?

What resolution is VCD?

704×480
The VCD standard also features the option of DVD-quality still images/slide shows with audio, at resolutions of 704×480 (NTSC) or 704×576 (PAL/SECAM).

What is VCD subject?

Visual Communication Design is an ideal study to undertake if you enjoy drawing and designing for screen and print communications. You’ll also examine the design industry and the professional practice of three different contemporary designers from each of the design fields; communication, environment and industrial.

What is a VCD in HVAC?

, Mechanical Engineer VCD (Volume control damper) is used to stabilize the flow through the air terminal in an HVAC System. For example, you have an FCU connected to 5 diffusers through duct. This is the simple answer.

What is a VCD damper used for?

VCD (Volume control damper) is used to stabilize the flow through the air terminal in an HVAC System. Volume Control Damper Designed for use in heating, ventilating and air conditioning systems. Joints are welded and protected by aluminum spray coating to prevent rusting.

How does a motorised VCD work?

Motorised VCDs are also used in which an actuator open and close the damper. In the case of VAV, air flow through the branches are controlled by the VAV itself. Manual adjusting / closing of the damper is not required. For this purpose VAVs contains, a damper, a damper actuator , controller, a digital thermostat (fixed in the room).

What is a variable frequency drive (VFD) in HVAC?

Variable Frequency Drive (VFD)… What Is It, And Why Use It In HVAC? A Variable Frequency Drive (VFD) controls the speed of a motor, specifically a three phase motor. To better understand a VFD, let’s examine the motors they control.
