Air Duct Design Program - The Best Software For Your Computer' title='Air Duct Design Program - The Best Software For Your Computer' />We describe how to find sometimes hidden manual duct dampers, and which way to set the duct damper lever to increase or decrease airflow through various sections of the ductwork and the building. We illustrate using air supply register controls to fine tune airflow in individual rooms or areas. We explain in detail automatic duct dampers and how they work. We also describe the use of individual airflow booster fans in the ductwork or in other locations to assure adequate cool or warm air supply in all areas.

Air Duct Design Program - The Best Software For Your' title='Air Duct Design Program - The Best Software For Your' />Manual Air Conditioning or Heating Duct Zone ControlsClick to enlarge any imageArticle ContentsClick to enlarge any imageManual heating or air conditioning zone dampers are mechanical doors that are manually by hand open or closed in order to control the amount of warm or cool air flowing to a particular room or area in a building. You can see two black manual duct damper handles on the white asbestos paper covered heating ducts in the photo at above left. By totally or partially closing the damper door, the owner or occupants of the building can balance the flow of conditioned air into various areas. But first you have to find all of the dampers sometimes the ductwork or zone dampers are all located close to the furnace or air conditioner, but in some buildings there may be quite remote dampers. So if air flow is too much or too little in some areas of the building, in addition to checking for crushed or disconnected air ducts, look for a stealth damper whose location may not have been immediately obvious this means looking on all accessible sides of all surfaces of the ductwork. Only a fool would have put a manual duct damper where you cant reach it, rightBecause it can be tough for a new owner of an older home to even imagine, much less find where these duct air flow balancing controls are located, we include more photographs of what a manual duct air flow damper control lever might look like. At below left our red arrow shows the direction of warm air movement out of a supply plenum and into ductwork, and our blue line shows the position of the duct damper blocking most but not all of the airflow. Shown in another example at above right, a manual zone damper or heating duct damper or cooling duct damper is particularly valuable in balancing air flow in buildings whose HVAC system includes long duct runs to some areas and short duct runs to other areas. This damper is in the at about 8. If we take no steps to balance the air flow among building areas, when the blower fan is running, the rooms closest to the blower will receive the most air flow and more distant rooms can be difficult to heat or cool. How do I Set the Duct Damper Handle in What Position In general, the handle of the duct airflow control lever or damper is parallel to the damper itself, so if the zone airflow control handle is across the duct it is closing off air flow. That is, the position of the duct damper handle also indicates the position of the actual damping baffle inside the ductwork. If the duct damper handle is parallel to the direction of the ductwork the damper is probably wide open photo at left. But if airflow control doesnt seem to work as predicted, some further checking is in order, since its possible to mount the duct damper handle improperly. The photo at left shows the duct damper handle turned parallel to the direction in which this old asbestos paper covered heating duct runs, so this airflow damper is in the open position. 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. But when an air duct serves multiple rooms in a building,and when we wish that entire area to receive more or less air flow compared with other building areas,it is simpler and more reliable to use a duct damper or zone damper to control the each heated or cooled area at once. Automatic Heating or Air Conditioning Zone Damper Controls. What is an automatic duct damper and how do they work Automatic heating or air conditioning zone dampers are mechanical doors that open or shut under thermostatic control to provide individual area or heating or cooling zone control in buildings served by a single warm air heater or central air conditioner. In response to individual room thermostats the damper opens to permit conditioned air to flow into that room or building area when needed. An automatic duct damper is usually controlled by a room thermostat, which opens or closes a metal baffle inside of a warm air or cool air heating or cooling duct in order to provide multiple heating zone control in a building. The duct damper is located in an air duct and blocks the flow of warm or cool air into building rooms. It has nothing to do with venting flue gases up a chimney. Our photo shows a motorized zone damper or air duct zone control produced by Trol. ATemp a producer of automatic heating system controls. This unit is an automatic opposed blade duct damper. Here is a commercial automatic air supply register control which contains a booster fan as well. You can spot an automatic zone damper on duct work by noticing that there is an external motor mounted on the ducts in one or more locations. When heating or cooling are not needed in that building area or zone, the duct damper remains in the closed position. Our photo shows a commercial duct damper in a New York City office building. In this case the damper is controlling airflow out of a supply duct into a single ceiling supply plenum and register. Automatic Fire Damper in Ductwork and how they work. The automatic firesmoke damper operates usually by automatically closing a door or doors within the damper on the detection of a temperature increase or by operation of a separate smoke detector.

In event of a fire these doors are intended to be automatically closed. Similar dampers may be installed right in HVAC ducts where the ducts pass between different building areas.
