2. Internal combustion engine cooling - Wikipedia

   en.wikipedia.org/wiki/Internal_combustion_engine...

   Most liquid-cooled engines use a mixture of water and chemicals such as antifreeze, rust inhibitors, and other additives. These antifreeze mixtures, also known as "engine coolant," are typically glycol-based fluids that contain a mixture of ethylene glycol, additives, and water. Common types of coolants include Inorganic Acid Technology (IAT ...

3. Antifreeze - Wikipedia

   en.wikipedia.org/wiki/Antifreeze

   An antifreeze mixture is used to achieve freezing-point depression for cold environments. Common antifreezes also increase the boiling point of the liquid, allowing higher coolant temperature. [1] However, all common antifreeze additives also have lower heat capacities than water, and do reduce water's ability to act as a coolant when added to ...

4. Cooling bath - Wikipedia

   en.wikipedia.org/wiki/Cooling_bath

   Cooling baths are generally one of two types: (a) a cold fluid (particularly liquid nitrogen, water, or even air) — but most commonly the term refers to (b) a mixture of 3 components: (1) a cooling agent (such as dry ice or ice); (2) a liquid "carrier" (such as liquid water, ethylene glycol, acetone, etc.), which transfers heat between the ...

5. Refrigerant - Wikipedia

   R-134 (without the "a" suffix) would have a molecular structure of 1,1,2,2-Tetrafluoroethane. The same numbers are used with an R- prefix for generic refrigerants, with a "Propellant" prefix (e.g., "Propellant 12") for the same chemical used as a propellant for an aerosol spray , and with trade names for the compounds, such as " Freon 12".

6. R-410A - Wikipedia

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

   However, like methane, R-410A has a global warming potential (GWP) that is appreciably worse than CO 2 (GWP = 1) for the time it persists. R-410A is a mixture of 50% HFC-32 and 50% HFC-125. HFC-32 has a 4.9 year lifetime and a 100-year GWP of 675 and HFC-125 has a 29-year lifetime and a 100-year GWP of 3500.
