A research team led by Professor Li Bing at the Institute of Metal Research, Chinese Academy of Sciences, has published groundbreaking findings in the top international journal Nature, discovering for the first time the “dissolution-compression effect,” bringing a revolutionary breakthrough to the refrigeration industry. This technology uses ammonium thiocyanate solution as the core working fluid. Through a cyclic process of pressurized salt precipitation releasing heat and depressurized salt dissolution absorbing heat, it can achieve a temperature drop of nearly 30°C within 20 seconds, with a temperature reduction exceeding 50°C in high-temperature environments. The single-cycle cooling capacity reaches 67 joules/gram, more than 10 times that of traditional solid compression materials. Its theoretical efficiency reaches 77%, far exceeding the 40%-60% efficiency bottleneck of traditional compressor refrigeration. It also boasts three major advantages: low carbon footprint, large cooling capacity, and high heat exchange rate, potentially revolutionizing the refrigeration landscape in high-energy-consuming fields such as data centers and industrial cooling.
