Damper (flow) A damper is 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. Its operation can be manual or automatic. Manual dampers are turned by a handle on the outside of a duct.

- Turning the handle to a position parallel with the duct line will open the damper completely. Turning the handle to a position that’s perpendicular to the duct will close off the line and block any airflow. Handle positions that sit in between open and close deliver more or less conditioned air to specific zones.

Dampers Dampers regulate room temperature and efficiently balance the supply of air coming from an HVAC unit by reducing the level of air flow or heat to unoccupied rooms. This supplies the home or building with more air flow to areas of greater need.

The AIRMATIC air suspension system. Bumpy country road or modern motorway: the AIRMATIC air suspension system adapts the suspension to the prevailing conditions. The damping of each wheel self-adjusts according to the current driving situation and the condition of the road. This happens fast and precisely by means of two separate valves for rebound and compression in each damper. AIRMATIC thereby provides maximum ride comfort for any situation.

Glossary Damper-a metal device inside the fireplace chimney used to reduce or close the opening between the firebox and flue; stops cold chimney drafts. Direct Vent-in reference to a gas fireplace, it has a chimney that can vent horizontally or vertically to the roof using a double wall flue. It has a completely enclosed firebox with a pane of glass that cannot be removed. It draws air for combustion through a double wall flue and expels gases to the outside as well.

Guide to Zone Dampers for Heating & Cooling Air Duct Controls How to install & use manual or automatic HVAC zone dampers Using an Air Supply Register as a Heating or Cooling Air Flow Damper or Control. As we show here, an alternative to manual heating or cooling air zone dampers is the use of mechanical louvers that can be opened or closed at individual supply air registers.

A Stuck Damper Between the Refrigerator & Freezer A stuck damper restricts that airflow, causing the air in the refrigerator to become warm -- sometimes too warm to keep the food fresh. Other features of a refrigerator's cooling system might also be affecting the damper's operation, so it may not be an isolated problem.

Chimney However, the advantage of a throat damper is that it seals off the living space from the air mass in the chimney, which, especially for chimneys positioned on an outside of wall of the home, is generally very cold. It is possible in practice to use both a top damper and a throat damper to obtain the benefits of both.

- File damper is a device designed to impede the spread of fire through walls, floors and partitions. Its construction includes a galvanized steel frame and a fusible link, a heat sensitive device (usually set at 165° F). When the fusible link opens it releases the damper components to close.

How does a vent damper increase furnace efficiency? automatic vent damper . The typical automatic vent damper is an electrically controlled flap that sits in the vent connector, just downstream (after) of the draft hood (draft diverter). It's just a fancy sock to stop air leaking up the chimney when the furnace is off. There are also heat activated vent dampers, but these are less common.

- Type-A Fire Damper: Used when the airflow interruption from the stack of blades in the fire damper frame is not a prime concern or consideration. Type-A dampers are the easiest and fastest type to install and are mostly used in low-pressure part of duct systems (up to 2” w.c.). Type-B Fire Damper: Used when airflow or velocity in the duct is a concern.

What is a Barometric Damper? One of the most misunderstood items inside a boiler room is a barometric damper. The barometric damper is used to control the draft inside a boiler. It is installed on boilers that use a Category I vent. To understand how the barometric damper operates, we need to understand what draft is. We all know that when air is heated, it will rise. Hot air is less desnser than cool air and it weighs less.

- Another type of automatic backdraft damper is. referred to as a stack cap or a discharge cap. Stack. caps are simply two opposed blade dampers mounted. atop a roof fan, complete with a protective wind band. that allows air to be exhausted while excluding the ele-. ments when not operating (see Figure 2). Figure 1.

Pros and Cons of Using a Backdraft Damper Cons. While the damper may be helpful in keeping cold air outside, this may be limiting when cool air is welcome indoors. This is because the damper is designed to facilitate air flow in one direction only: out of the house. The damper cannot help harness cool air when it occurs during the summer.

- rahul gopinath. An air handler, or air handling unit (often abbreviated to AHU), is a device used to condition and circulate air as part of a heating, ventilating, and air-conditioning (HVAC) system. Usually, an air handler is a large metal box containing a blower, heating and/or cooling elements, filter racks or chambers, sound attenuators, and dampers.
