The phenomenon, when taken to mean "hot water freezes faster than cold", is difficult to reproduce or confirm because it is ill-defined. [4] Monwhea Jeng proposed a more precise wording: "There exists a set of initial parameters, and a pair of temperatures, such that given two bodies of water identical in these parameters, and differing only in initial uniform temperatures, the hot one will ...
A Crosley IcyBall with cold side ball on left, hot side ball on right. Icyball is a name given to two early refrigerators, one made by Australian Sir Edward Hallstrom in 1923, and the other design patented by David Forbes Keith of Toronto (filed 1927, granted 1929), [1] [2] and manufactured by American Powel Crosley Jr., who bought the rights to the device.
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.
A refrigerator maintains a temperature a few degrees above the freezing point of water. The optimal temperature range for perishable food storage is 3 to 5 °C (37 to 41 °F). [3] A freezer is a specialized refrigerator, or portion of a refrigerator, that maintains its contents’ temperature below the freezing point of water. [4]
The refrigerator is a small unit placed over a campfire, that can later be used to cool 15 litres (3.3 imp gal; 4.0 US gal) of water to just above freezing for 24 hours in a 30 °C (86 °F) environment. [4] The concept was similar to an early refrigeration device known as an Icyball.
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.
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
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. [ 1 ] [ 2 ] The cooling power is provided by the heat of mixing of the helium-3 and helium-4 isotopes.
