A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [ 1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.
Sabbath mode. Sabbath mode, also known as Shabbos mode (Ashkenazi pronunciation) or Shabbat mode, is a feature in many modern home appliances, including ovens, [ 1] dishwashers, [ 2] and refrigerators, [ 3] which is intended to allow the appliances to be used (subject to various constraints) by Shabbat-observant Jews on the Shabbat and Jewish ...
A 3He/4He 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. [ 1][ 2] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
Magnetic refrigeration. Gadolinium alloy heats up inside the magnetic field and loses thermal energy to the environment, so it exits the field and becomes cooler than when it entered. Magnetic refrigeration is a cooling technology based on the magnetocaloric effect. This technique can be used to attain extremely low temperatures, as well as the ...
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 ...
June 2000. Manufacturer. LG Electronics. The LG Internet Digital DIOS (also known as R-S73CT) is an internet refrigerator released by LG Electronics in June 2000. The technology is the result of a project that started in 1997 and staffed by a team of 55 researchers with a budget cost of 15 billion won (US$49.2 million).
Direct cool. Direct cool is one of the two major types of techniques used in domestic refrigerators, the other being the "frost-free" type. Direct-cool refrigerators produce the cooling effect by a natural convection process from cooled surfaces in the insulated compartment that is being cooled. Water vapor that contacts the cooled surface freezes.
Globally. Food in a refrigerator with its door open. A refrigerator, commonly fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room ...
