    en.wikipedia.org/wiki/Heat_recovery_ventilation

    Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...

  4. Heating, ventilation, and air conditioning - Wikipedia

    en.wikipedia.org/wiki/Heating,_ventilation,_and...

    Most modern hot water boiler heating systems have a circulator, which is a pump, to move hot water through the distribution system (as opposed to older gravity-fed systems). The heat can be transferred to the surrounding air using radiators, hot water coils (hydro-air), or other heat exchangers. The radiators may be mounted on walls or ...

  5. Underground mine ventilation - Wikipedia

    en.wikipedia.org/wiki/Underground_mine_ventilation

    Flow-through ventilation is the main ventilation circuit for the mine. Air enters the mine from the surface via a shaft, ventilation raise or adit.The air is distributed through the mine via internal ventilation raises and ramps, and flows are controlled by regulators and permanently mounted ventilation fans.

  6. Gas venting - Wikipedia

    en.wikipedia.org/wiki/Gas_venting

    The U.S. Department of Energy reports that a majority of the venting within U.S. gas industry operations in year 2017 occurred at compressor stations and from pneumatically operated controllers and regulators. [6]: 7 Improved maintenance strategies and advanced equipment technologies either exist or are being developed to reduce such venting. [17]

  7. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    In the U.S., every plumbing fixture must also be coupled to the system's vent piping. [1] Without a vent, negative pressure can slow the flow of water leaving the system, resulting in clogs, or cause siphonage to empty a trap. The high point of the vent system (the top of its "soil stack") must be open to the exterior at atmospheric pressure.

  8. Ventilation (firefighting) - Wikipedia

    en.wikipedia.org/wiki/Ventilation_(firefighting)
