Researchers have created a new cooling method called ionocaloric cooling. This method could be safer and better for the environment than current cooling systems.
Regular fridges use fluids to carry heat away. These fluids can harm the environment. Ionocaloric cooling does not use these harmful fluids. Instead, it changes the state of materials, like how ice melts into water, to cool the air around it.
This method uses charged particles, called ions. Adding salt can help ice melt without heat. Salt is also used in ionocaloric cooling to change a fluid’s state to lower temperatures.
In laboratory tests, researchers found that a small electric charge created a temperature drop of 25 °C. This performance is better than many current cooling methods. The researchers think this technology can meet goals for safety and efficiency.
Now, the next step is to take this method from the lab to real-world use. It could be used for both cooling and heating in the future.
