Researchers unveil a record-breaking eco-friendly refrigeration device with 48% efficiency boost, set to advance cooling and cut energy use.
The system achieves a temperature lift of 75 K by expanding the super elastic temperature window of NiTi shape memory alloys.The Hong Kong University of Science and Technology team claims that its system offers record-breaking cooling performance and an efficiency of over 48 percent.
“In the future, with the continuous advancement of materials science and mechanical engineering, we are confident that elastocaloric refrigeration can provide next-generation green and energy-efficient cooling and heating solutions to feed the huge worldwide refrigeration market, addressing the urgent task of decarbonization and global warming mitigation,” said Sun Qingping, from the HKUST’s Department of Mechanical and Aerospace Engineering, in aHigh global warming potential refrigerants are...
These materials are non-volatile, meaning they don’t readily evaporate into a gas, which means they have no significant impact on global warming. This makes them highly promising for use in alternative refrigeration technologies.
