Now in almost everyone’s home freezer is available. The method used in these refrigerators and traditional cooling systems is to first evaporate a liquid, pass it through pipes in gaseous form, then condense it and turn it back into a liquid. On the other hand, these refrigerants can be harmful to the environment.

Ionocaloric cooling A new method called as an environmentally friendly and safer alternative appears before us. This method, developed by researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, takes advantage of the energy storage and release processes when materials change phase. For example, when ice melts, it absorbs the heat around it and this has a cooling effect. The new method allows the same effect to be achieved at lower temperatures when certain ions are used.

In terms of efficiency, things can be better

Researchers, ionocaloric cycle It also showed that it can compete with existing methods and even be better in terms of efficiency. Together with developments in this area, this has the potential to pave the way for lower energy consumption. In the experiments, a salt containing sodium and iodine was used and a temperature change of 25 degrees was achieved.

The gases used in current conventional systems are based on hydrofluorocarbons, which have a global warming potential. Countries participating in the Kigali Amendment will reduce production and consumption of HFCs over the next 25 years. committed to a reduction of at least 800 percent was found. The new method could play a major role in achieving this goal.
