flag Chinese scientists found a new cooling method using a salt solution that drops temperature by nearly 30°C in 20 seconds, offering efficient, low-emission cooling.

flag Chinese researchers have discovered a new cooling effect, the dissolution barocaloric effect, in an ammonium thiocyanate salt solution, enabling a nearly 30°C temperature drop in 20 seconds at room temperature. flag When pressure is released, the salt rapidly dissolves, absorbing heat and cooling the environment. flag This fluid-based system combines refrigerant and heat transfer in one medium, offering high efficiency, strong cooling capacity, and low emissions. flag A proposed four-step cycle achieved 67 joules of heat absorption per gram and up to 77% energy efficiency in simulations. flag The breakthrough could help meet rising global cooling demand, which may more than triple by 2050, and reduce emissions from energy-intensive applications like data centers. flag The findings were published in Nature.
