Say hello to ionocaloric cooling: a new way to lower the mercury that has the potential to replace existing methods with something that is safer and friendlier to the planet.
that has the potential to replace existing methods with something that is safer and friendlier to the planet.
Raise the temperature on a block of ice, it'll melt. What we might not see so easily is that melting absorbs heat from its surroundings, effectively cooling it. The researchers modeled the theory of the ionocaloric cycle to show how it could potentially compete with, or even improve upon, the efficiency of refrigerants in use today. A current running through the system would move the ions in it, shifting the material's melting point to change temperature.The team also ran experiments using a salt made with iodine and sodium, to melt ethylene carbonate.
