  2. Air cycle machine - Wikipedia

    en.wikipedia.org/wiki/Air_cycle_machine

    Air cycle machines were first developed in the 19th century for providing chilling on ships. The technique is a reverse Brayton cycle (the thermodynamic cycle of a gas turbine engine) and is also known as a Bell Coleman cycle or "Air-Standard Refrigeration Cycle".

  3. Steam jet cooling - Wikipedia

    en.wikipedia.org/wiki/Steam_jet_cooling

    Steam jet cooling uses a high-pressure jet of steam to cool water or other fluid media. Typical uses include industrial sites, where a suitable steam supply already exists for other purposes or, historically, for air conditioning on passenger trains which use steam for heating. Steam jet cooling experienced a wave of popularity during the early ...

  4. Vapor-compression refrigeration - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression...

    A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.

  5. Bleed air - Wikipedia

    en.wikipedia.org/wiki/Bleed_air

    Bleed air in aerospace engineering is compressed air taken from the compressor stage of a gas turbine, upstream of its fuel-burning sections.Automatic air supply and cabin pressure controller (ASCPC) valves bleed air from low or high stage engine compressor sections; low stage air is used during high power setting operation, and high stage air is used during descent and other low power setting ...

  6. Air conditioning - Wikipedia

    en.wikipedia.org/wiki/Air_conditioning

    Air conditioning, often abbreviated as A/C (US) or air con (UK), [1] is the process of removing heat from an enclosed space to achieve a more comfortable interior temperature (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical ...

    en.wikipedia.org/wiki/ATA_100

    The standard numbering system was published by the Air Transport Association on June 1, 1956. While the ATA 100 numbering system has been superseded, it continued to be widely used until it went out of date in 2015, especially in documentation for general aviation aircraft, on aircraft Fault Messages (for Post Flight Troubleshooting and Repair ...
