An adjustable iron plate or shutter fitted across a boiler flue to regulate the draught. Often provided with an automatic electro-mechanical device that closes the damper to prevent heat from escaping through the funnel during burner stop periods.
This is a plate that can be opened or closed to control and balance the airflow throughout the air handler's ductwork. This control is most obvious in systems with a ‘zoning' option where cooling can be confined or regulated in individual rooms. Click on the ' Ductless air conditioners' link to learn more about these systems.
A device that is located in ductwork to adjust air flow. This movable plate opens and closes to control airflow. Dampers are used effectively in zoning to regulate airflow to certain rooms. There are basically two types of dampers: Manual and motorized. A manual damper generally consists of a sheet metal (or similar material) flap, shaped to fit the inside of a round or rectangular duct. By rotating a handle located outside of the duct a technician can adjust (see Balancing) air flow to match the needs of a particular area or room. A motorized damper is generally used in a zoned system (see Zoning) to automatically deliver conditioned air to specific rooms or zones. In particular, the following types, can be distinguished: Multiple leaf dampers, comprising of a number of blades (or shutters) of opposed or parallel leaf type. Single leaf dampers (the flap being mounted at one end), commonly called splitter dampers. Hit-and-miss dampers, having two or more slotted slide mechanism. Butterfly dampers, with two flaps in "V" arrangement.
a plate which is adjusted inside the flue or vent of a fireplace or furnace that controls the draft from the flame or that may prevent loss of conditioned air from within a building or back drafting of outside air
A device to regulate flow of gas through a stack or duct and to control draft in a heater. A typical damper consists of a flat plate connected to a shaft, which can be rotated, similar to a butterfly valve. A damper may have more than one blade.
The mechanism responsible for the regulation of airflow in a fan system; dampers consist of inlet dampers, which regulate airflow into the system, and outlet dampers, which control air movement out of the system.
A manually or automatically controlled device to regulate draft or the rate of flow of air or combustion gases. Volume damper. A device that, when installed, will restrict, retard or direct the flow of air in a duct, or the products of combustion in a heat-producing appliance, its vent connector, vent or chimney therefrom.
In a duct or chimney, a damper is a valve or plate that stops or regulates the flow of air. 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. In the case of cutting off air, it is often manual, turned by a handle on the outside of a duct.
A foot pedal found on pianos. Normally a felt pad presses against the piano strings so they don't keep ringing as you play other notes (the pad "dampens" the ringing). Pressing down the damper pedal moves the felt pad off the strings so they can ring. On a synth, pressing the damper pedal extends the "sustain" portion of the sampled waveform. On the 01, a damper pedal can be plugged into the DAMPER jack on the back panel. Pressing and releasing the damper pedal inserts a MIDI Control Code into your sequence. If MIDI Control Codes are disabled, the damper will work when you play live, but the MIDI control codes will not be recorded in SEQ mode. If your damper isn't being recorded in SEQ mode, check to see if the damper is enabled: 1. Press GLOBAL 2. Press UP once (to move the highlight to the bottom line) 3. Press "D" or "E" to highlight "CTRL:" 4. Press UP ARROW so the display shows "CTRL:ENA".
Damper is a traditional Australian outback food prepared by swagmen, drovers and other travellers. It consists of a wheat flour based, unleavened bread baked in the coals of a campfire. Damper is an iconic Australian dish.
This is the term used for the flat spring used in some single or dual spring applications. The flat spring allows a more complex spring for valve control without raising the spring tension considerably.
