  2. Auto-defrost - Wikipedia

    en.wikipedia.org/wiki/Auto-defrost

    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.

  3. Dilution refrigerator - Wikipedia

    en.wikipedia.org/wiki/Dilution_refrigerator

    The working fluid is 3 He, which is circulated by vacuum pumps at room temperature. The 3 He enters the cryostat at a pressure of a few hundred millibar. In the classic dilution refrigerator (known as a wet dilution refrigerator), the 3 He is precooled and purified by liquid nitrogen at 77 K and a 4 He bath at 4.2 K.

  4. Why sudden loud booms sometimes occur when it's very cold outside

    www.aol.com/weather/why-sudden-loud-booms...

    During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...

    An ice pack Shipment of vaccine in insulated box with gel packs 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 ...

    The 1950s and 1960s saw technical advances like automatic defrosting and automatic ice making. More efficient refrigerators were developed in the 1970s and 1980s, even though environmental issues led to the banning of very effective (Freon) refrigerants. Early refrigerator models (from 1916) had a cold compartment for ice cube trays.

  7. Pulse tube refrigerator - Wikipedia

    As a result, the gas also moves from left to right and back while the pressure within the system increases and decreases. If the gas from the compressor space moves to the right, it enters the regenerator with temperature T H and leaves the regenerator at the cold end with temperature T L, hence heat is transferred into the regenerator material ...

    His 1856 patent was for a vapour-compression system using ether, alcohol, or ammonia. He built a mechanical ice-making machine in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Victoria, and his first commercial ice-making machine followed in 1854. Harrison also introduced commercial vapour-compression refrigeration to ...

  9. Dry ice - Wikipedia

    en.wikipedia.org/wiki/Dry_ice

    In laboratories, a slurry of dry ice in an organic solvent is a useful freezing mixture for cold chemical reactions and for condensing solvents in rotary evaporators. [38] Dry ice and acetone forms a cold bath of −78 °C (−108 °F; 195 K), which can be used for instance to prevent thermal runaway in a Swern oxidation .
