    An air purifier or air cleaner is a device which removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as being beneficial to allergy sufferers and asthmatics , and at reducing or eliminating second-hand tobacco smoke .

  3. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    Air ioniser and purifier with its dust collection plates removed. Air ionisers are used in air purifiers to remove particles from air. [3] Airborne particles become charged as they attract charged ions from the ioniser by electrostatic attraction. The particles in turn are then attracted to any nearby earthed (grounded) conductors, either ...

    en.wikipedia.org/wiki/HVAC_control_system

    After the control of air flow and temperature was standardized, the use of electromechanical relays in ladder logic to switch dampers became standardized. Eventually, the relays became electronic switches, as transistors eventually could handle greater current loads. By 1985, pneumatic controls could no longer compete with this new technology ...

  6. Central heating - Wikipedia

    en.wikipedia.org/wiki/Bang–bang_control

    In control theory, a bang–bang controller (hysteresis, 2 step or on–off controller), is a feedback controller that switches abruptly between two states. These controllers may be realized in terms of any element that provides hysteresis. They are often used to control a plant that accepts a binary input, for example a furnace that is either ...
