  2. Steam jet cooling - Wikipedia

    en.wikipedia.org/wiki/Steam_jet_cooling

    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 ...

  3. Vortex tube - Wikipedia

    en.wikipedia.org/wiki/Vortex_tube

    Separation of a compressed gas into a hot stream and a cold stream. The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 ...

  4. Absorption refrigerator - Wikipedia

    en.wikipedia.org/wiki/Absorption_refrigerator

    An absorption refrigerator is a refrigerator that uses a heat source to provide the energy needed to drive the cooling process. Solar energy, burning a fossil fuel, waste heat from factories, and district heating systems are examples of convenient heat sources that can be used. An absorption refrigerator uses two coolants: the first coolant ...

  5. Vapor-compression refrigeration - Wikipedia

    en.wikipedia.org/.../Vapor-compression_refrigeration

    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. It is also used in domestic and commercial refrigerators, large-scale warehouses ...

  6. Refrigeration - Wikipedia

    en.wikipedia.org/wiki/Refrigeration

    Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). [1][2] Refrigeration is an artificial, or human-made, cooling method. [1][2] Refrigeration refers to the process by which energy ...

  7. Brayton cycle - Wikipedia

    en.wikipedia.org/wiki/Brayton_cycle

    A Brayton cycle that is driven in reverse uses work to move heat. This makes it a form of gas refrigeration cycle. When air is the working fluid, it is known as the Bell Coleman cycle. [20] This air-cooling technique is used widely in jet aircraft for air conditioning systems using bleed air tapped from the engine compressors. [how?] [dubious ...

  8. Pulse tube refrigerator - Wikipedia

    en.wikipedia.org/wiki/Pulse_tube_refrigerator

    The pressure varies gradually and the velocities of the gas are low. So the name "pulse" tube cooler is misleading, since there are no pulses in the system. The piston moves periodically from left to right and back. As a result, the gas also moves from left to right and back while the pressure within the system increases and decreases.

  9. Injector - Wikipedia

    en.wikipedia.org/wiki/Injector

    For use in producing a vacuum pressure in steam jet cooling systems. For expansion work recovery in air conditioning and refrigeration systems. For enhanced oil recovery processes in the oil & gas Industry. For the bulk handling of grains or other granular or powdered materials. The construction industry uses them for pumping turbid water and ...
