  2. Free cooling - Wikipedia

    en.wikipedia.org/wiki/Free_cooling

    For a human-powered version, see yakhchal.. When the ambient air temperature drops to a set temperature, a modulating valve allows all or part of the chilled water to by-pass an existing chiller and run through the free cooling system, which uses less power and uses the lower ambient air temperature to cool the water in the system.

  3. Chiller - Wikipedia

    en.wikipedia.org/wiki/Chiller

    A liquid (glycol based) chiller with an air cooled condenser on the rooftop of a medium size commercial building. In air conditioning systems, chilled coolant, usually chilled water mixed with ethylene glycol, from a chiller in an air conditioning or cooling plant is typically distributed to heat exchangers, or coils, in air handlers or other types of terminal devices which cool the air in ...

  4. Chilled water - Wikipedia

    en.wikipedia.org/wiki/Chilled_water

    The water in the chilled water circuit will be lowered to the Wet-bulb temperature or dry-bulb temperature before proceeding to the water chiller, where it is cooled to between 3 and 6 °C and pumped to the air handler, where the cycle is repeated. [3] The equipment required includes chillers, cooling towers, pumps and electrical control ...

  5. Glycol chiller - Wikipedia

    en.wikipedia.org/wiki/Glycol_chiller

    Glycol chillers are a specific kind of refrigeration system, often used to cool a variety of liquids, including alcohol and other beverages. Using a chiller allows producers to lower the temperature of the product dramatically over a short period of time, depending on the production needs.

  6. Worthington Corporation - Wikipedia

    en.wikipedia.org/wiki/Worthington_Corporation

    The large tax loss was also valuable. Worthington was expected to continue to earn steady profits, but could use the tax loss to avoid paying taxes. [ 24 ] The stockholders of Studebaker and Worthington approved the merger despite rumors that the Federal Trade Commission considered the merger would be "substantially anti-competitive". [ 25 ]

  7. Dilution refrigerator - Wikipedia

    en.wikipedia.org/wiki/Dilution_refrigerator

    Schematic diagram of a cryogen-free, or dry, dilution refrigerator precooled by a two-stage pulse tube refrigerator, indicated by the dotted rectangle. A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK , with no moving parts in the low-temperature region.

  8. 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.

  9. Thermal efficiency - Wikipedia

    en.wikipedia.org/wiki/Thermal_efficiency

    In thermodynamics, the thermal efficiency is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc.
