Revolutionizing Cooling Technology: A New Crystal Could Make Refrigerators and Air Conditioners Environmentally Friendly

Refrigerators and freezers typically get their cooling power from environmentally harmful fluids

A groundbreaking discovery by researchers at Deakin University in Australia may pave the way for a significant shift in cooling technology. Traditional refrigeration and air conditioning systems rely on liquids that contribute to the greenhouse effect, exacerbating climate change. However, a new type of crystal developed by Jenny Pringle and her team offers a sustainable and environmentally friendly alternative.

These “plastic crystals” exhibit a unique property where their molecules can reorient under pressure, transitioning from a disordered state to an ordered grid-like structure. This transformation results in the absorption of heat, effectively cooling the surrounding area. Unlike previous materials capable of pressure-based cooling, the crystals created by Pringle can operate at temperatures ranging from -37°C to 10°C, making them suitable for household refrigeration units.

While the potential of these crystals to revolutionize the cooling industry is promising, there are challenges that need to be addressed before implementation. The high pressures required to activate the cooling effect are currently a limiting factor, as they far exceed atmospheric pressure. Researchers like David Boldrin from the University of Glasgow acknowledge the transformative impact of such materials but emphasize the need to overcome the pressure obstacle.

Another concern raised by Bing Li at the Chinese Academy of Sciences is the potential decrease in heat absorption efficiency with repeated use, as the molecular grid within the crystals may become strained over time. Despite these challenges, experts remain optimistic about the future applications of this technology and believe that with further development, it could soon become a viable solution for sustainable cooling.
