  2. Immersion cooling - Wikipedia

    en.wikipedia.org/wiki/Immersion_cooling

    Heat is removed from the system by putting the coolant in direct contact with hot components, and circulating the heated liquid through heat exchangers. This practice is highly effective as liquid coolants can absorb more heat from the system than air. Immersion cooling has many benefits, including but not limited to: sustainability ...

  3. Antifreeze - Wikipedia

    en.wikipedia.org/wiki/Antifreeze

    Proper engine coolant and a pressurized coolant system obviate these shortcomings of water. With proper antifreeze, a wide temperature range can be tolerated by the engine coolant, such as −34 °F (−37 °C) to +265 °F (129 °C) for 50% (by volume) propylene glycol diluted with distilled water and a 15 psi pressurized coolant system.

  4. Absorption refrigerator - Wikipedia

    en.wikipedia.org/wiki/Absorption_refrigerator

    Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).

  5. R-410A - Wikipedia

    en.wikipedia.org/wiki/R-410A

    The phase-down mandated by the AIM Act will lead to R-410A's replacement by other refrigerants beginning in 2022. Alternative refrigerants are available, including hydrofluoroolefins , R-454B (a zeotropic blend of R-32 and R-1234yf ), hydrocarbons (such as propane R-290 and isobutane R-600A ), and even carbon dioxide ( R-744 , GWP = 1).

  6. Refrigeration - Wikipedia

    en.wikipedia.org/wiki/Refrigeration

    When combining a passive daytime radiative cooling system with thermal insulation and evaporative cooling, one study found a 300% increase in ambient cooling power when compared to a stand-alone radiative cooling surface, which could extend the shelf life of food by 40% in humid climates and 200% in desert climates without refrigeration. The ...
