  2. Mpemba effect - Wikipedia

    en.wikipedia.org/wiki/Mpemba_effect

    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 ...

  3. Ice pack - Wikipedia

    en.wikipedia.org/wiki/Ice_pack

    An ice pack or gel pack is a portable bag filled with water, refrigerant gel, or liquid, meant to provide cooling. They can be divided into the reusable type, which works as a thermal mass and requires freezing, or the instant type, which cools itself down using chemicals but can only be used once.

  4. Ice spike - Wikipedia

    en.wikipedia.org/wiki/Ice_spike

    Water expands by 9% as it freezes. Occasionally the surface can freeze over except for a small hole; the continuing freezing and expansion of water that is below the surface ice then slowly pushes the remaining water up through the hole. Reaching very cold air, the edge of the extruded water freezes while remaining liquid in the center.

  5. Joule–Thomson effect - Wikipedia

    en.wikipedia.org/wiki/Joule–Thomson_effect

    So throttling from 200 bar to 1 bar gives a cooling from room temperature to below the freezing point of water. Throttling from 200 bar and an initial temperature of 133 K (point c in fig. 2) to 1 bar results in point d, which is in the two-phase region of nitrogen at a temperature of 77.2 K.

  6. Auto-defrost - Wikipedia

    en.wikipedia.org/wiki/Auto-defrost

    "Frost-Free" refrigerator/freezer units usually use a heating element to defrost their evaporators, a pan to collect and evaporate water from the frost that melts from the cold plate and/or evaporator coil, a timer which turns off the compressor and turns on the defrost element usually from once to 4 times a day for periods usually ranging from ...

  7. Cascade refrigeration - Wikipedia

    en.wikipedia.org/wiki/Cascade_refrigeration

    Alternatively, a liquid-to-liquid or similar heat exchanger may be used instead. The high-temperature system transfers heat to a conventional condenser that carries the entire heat output of the system and may be passive, fan, or water-cooled. This is an auto-cascade process with two different refrigerants.

    When the water is frozen solid, go ahead and peel back the balloon with a pair of scissors. The final product will be a set of colorful ice marbles that look like decorative glass, perfect for ...

    en.wikipedia.org/wiki/Magnetic_refrigeration

    The GeoThermag system showed the ability to produce cold water even at 281.8 K in the presence of a heat load of 60 W. In addition, the system has shown the existence of an optimal frequency f AMR, 0.26 Hz, for which it was possible to produce cold water at 287.9 K with a thermal load equal to 190 W with a COP of 2.20.
