  2. Evaporative cooler - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooler

    Evaporative cooling of ordinary helium forms a 1-K pot, which can cool to at least 1.2 K. Evaporative cooling of helium-3 can provide temperatures below 300 mK. These techniques can be used to make cryocoolers, or as components of lower-temperature cryostats such as dilution refrigerators. As the temperature decreases, the vapor pressure of the ...

    A car cooler is an automobile evaporative cooler, sometimes referred to as a swamp cooler. [32] [33] Most are aftermarket relatively inexpensive accessories consisting of an external window-mounted metal cylinder without moving parts, but internal under the dashboard or center floor units with an electric fan are available.

    Fig. 6 The four stages in the cooling cycle of the GM cooler. The cycle can be divided in four steps, with Fig.6, as follows: The cycle starts with the low-pressure (LP) valve closed, the high-pressure (HP) valve open, and the displacer all the way to the right (so in the cold region). All the gas is at room temperature. From a to b.

    en.wikipedia.org/wiki/Rolls-Royce_Goshawk

    The Rolls-Royce Goshawk was a development of the Rolls-Royce Kestrel that used evaporative or steam cooling. In line with Rolls-Royce convention of naming piston engines after birds of prey, it was named after the goshawk. The engine first ran in 1933 and provided 660 horsepower (490 kW).

  6. 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.

  7. Evaporative cooling chambers - Wikipedia

    en.wikipedia.org/wiki/Evaporative_cooling_chambers

    Evaporative cooling chambers (ECCs), also known as "zero energy cool chambers" (ZECCs), are a type of evaporative cooler, which are simple and inexpensive ways to keep vegetables fresh without the use of electricity. Evaporation of water from a surface removes heat, creating a cooling effect, which can improve vegetable storage shelf life.
