Damper

Damper is a device that controls the flow of air in an HVAC (Heating, Ventilation, and Air Conditioning) system. The damper is typically a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature and climate control.

Function

The function of a damper is to control the flow of air in an HVAC system. This is achieved by adjusting the damper's position, which can be either open, closed, or somewhere in between. The position of the damper is typically controlled by a thermostat, which adjusts the damper's position based on the desired temperature in a room or building.

Types of Dampers

There are several types of dampers, including:

• Zone Dampers: These are used in a zoned heating and cooling system to regulate the flow of air to different parts of a building. They are typically controlled by a zone control panel that is connected to multiple thermostats.

• Fire Dampers: These are used in air ducts to prevent the spread of fire inside the ductwork. They are designed to automatically close when they detect heat.

• Smoke Dampers: These are similar to fire dampers, but they are designed to prevent the spread of smoke in a building's HVAC system.

• Volume Control Dampers: These are used to adjust the volume of air flowing through a duct.
