2. Magnetorheological damper - Wikipedia

   en.wikipedia.org/wiki/Magnetorheological_damper

   A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [ 1 ] [ 2 ] [ 3 ] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.

3. Magnetic damping - Wikipedia

   en.wikipedia.org/wiki/Magnetic_damping

   Magnetic damping [1] is a form of damping that occurs when a magnetic field (i.e. a magnet) travels some distance through or past an electrical conductor (or vice versa).

4. Air-mixing plenum - Wikipedia

   en.wikipedia.org/wiki/Air-mixing_plenum

   The mix of fresh air and recirculated air can thus be adjusted to suit the needs of the building's occupants. Most systems will use motorized dampers to control the air mixing, and controlled by the building management system (BMS), or controls system. Typically as the fresh air and exhaust air dampers are driven from 0% open to 100% open, the ...

5. Magnetorheological fluid - Wikipedia

   en.wikipedia.org/wiki/Magnetorheological_fluid

   In the absence of external pressure the maximum shear strength is about 100 kPa. If the fluid is compressed in the magnetic field direction and the compressive stress is 2 MPa, the shear strength is raised to 1100 kPa. [3] If the standard magnetic particles are replaced with elongated magnetic particles, the shear strength is also improved. [4]

6. Damper (flow) - Wikipedia

   en.wikipedia.org/wiki/Damper_(flow)

   This damper can switch the electrical power to control additional "slave" dampers, minimizing the electrical load on the damper's control circuitry and power transformer. 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. In order to ...

7. MagneRide - Wikipedia

   en.wikipedia.org/wiki/MagneRide

   The dampers are filled with magnetorheological fluid, a mixture of easily magnetized iron particles in a synthetic hydrocarbon oil. In each of the monotube dampers is a piston containing two electromagnetic coils and two small fluid passages through the piston. The electromagnets are able to create a variable magnetic field across the fluid ...

8. Damping - Wikipedia

   en.wikipedia.org/wiki/Damping

   [15] In other words, the resistance caused by magnetic forces slows a system down. An example of this concept being applied is the brakes on roller coasters. [16] Magnetorheological Dampers (MR Dampers) use Magnetorheological fluid, which changes viscosity when subjected to a magnetic field. In this case, Magnetorheological damping may be ...

9. Building airtightness - Wikipedia

   en.wikipedia.org/wiki/Building_airtightness

   Given its impacts on heat losses, good building airtightness may allow installation of smaller heating and cooling capacities. Conversely, poor airtightness may prevent achieving the desired indoor temperature conditions if the equipment has not been sized with proper estimates of infiltration heat losses.
