  2. Subcooling - Wikipedia

    en.wikipedia.org/wiki/Subcooling

    The term subcooling (also called undercooling) refers to the intentional process of cooling a liquid below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) liquid water is termed "subcooled". Subcooling is a common stage in refrigeration cycles and steam turbine cycles.

  3. Economizer - Wikipedia

    en.wikipedia.org/wiki/Economizer

    The subcooling term refers to cooling the liquid below its boiling point. 10 °F (5.6 °C) of subcooling means it is 10 °F colder than boiling at a given pressure. As it represents a difference of temperatures, the subcooling value is not measured on an absolute temperature scale, only on a relative scale as a temperature difference.

    subcooling The condition where liquid refrigerant is colder than the minimum temperature required to keep it from boiling which would change it from a liquid to a gas phase. Sub cooling is the difference between its saturation temperature and the actual liquid refrigerant temperature.

  5. Supercooling - Wikipedia

    en.wikipedia.org/wiki/Supercooling

    As per the established international definition, supercooling means ‘cooling a substance below the normal freezing point without solidification’ [4] [5] While it can be achieved by different physical means, the postponed solidification is most often due to the absence of seed crystals or nuclei around which a crystal structure can form. The ...

    en.wikipedia.org/wiki/Flash-gas_(refrigeration)

    The incorporation of a subcooling stage after the receiver reduces even more the chances to observe flash gas. [5] This subcooling may be done in a reserved portion of the main condenser, or separately with a heat exchanger. Some receivers may incorporate an internal heat exchanger that draws heat form the subcooled liquid to superheat the gas ...

  9. Condenser (heat transfer) - Wikipedia

    en.wikipedia.org/wiki/Condenser_(heat_transfer)

    The earliest laboratory condenser, a "Gegenstromkühler" (counter-flow condenser), was invented in 1771 by the Swedish-German chemist Christian Weigel. [2]By the mid-19th century, German chemist Justus von Liebig would provide his own improvements on the preceding designs of Weigel and Johann Friedrich August Göttling, with the device becoming known as the Liebig condenser.
