  2. Negative room pressure - Wikipedia

    en.wikipedia.org/wiki/Negative_room_pressure

    Schematic of a network of rooms where air (shown in blue) flows in one direction from the corridor into the negative pressure room (green). Exhaust air is safely removed from the area through a ventilation system. Negative pressure is generated and maintained in a room by a ventilation system that continually attempts to move air out of the ...

  3. Air ioniser - Wikipedia

    en.wikipedia.org/wiki/Air_ioniser

    An air ioniser (or negative ion generator or Chizhevsky's chandelier) is a device that uses high voltage to ionise (electrically charge) air molecules. Negative ions, or anions , are particles with one or more extra electrons , conferring a net negative charge to the particle.

    The fan enclosure is directly behind the board, and the filters can be seen at the top. The safety interlock switch is at the bottom left. In the lower middle is the capacitor. Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of

  5. Negative air ions - Wikipedia

    en.wikipedia.org/wiki/Negative_air_ions

    Common gases that produce negative air ions include single-component gases such as nitrogen, oxygen, carbon dioxide, water vapor, or multi-component gases obtained by mixing these single-component gases. Various negative air ions are formed by combining active neutral molecules and electrons in the gas through a series of ion-molecule reactions ...

  6. Passive ventilation - Wikipedia

    en.wikipedia.org/wiki/Passive_ventilation

    Passive ventilation is the process of supplying air to and removing air from an indoor space without using mechanical systems. It refers to the flow of external air to an indoor space as a result of pressure differences arising from natural forces.

  8. Duct leakage testing - Wikipedia

    en.wikipedia.org/wiki/Duct_leakage_testing

    A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
