Core Viewpoint - The research team led by researcher Li Bing from the Institute of Metal Research, Chinese Academy of Sciences, has discovered the "Dissolution Pressure Lock Effect," which opens a new path for next-generation green refrigeration technology [1][2]. Group 1: Research Findings - The study reveals that solid-state phase change refrigeration materials, which avoid gas refrigerant emissions, have limitations such as slow thermal conductivity and high interfacial thermal resistance, hindering their application in high-power scenarios [1]. - The "Dissolution Pressure Lock Effect" was observed in ammonium thiocyanate solution, which exhibits remarkable thermal effects under pressure changes: heating occurs during pressurization, and rapid cooling occurs upon depressurization, with temperature dropping nearly 30 degrees Celsius within 20 seconds at room temperature [1][2]. - This phenomenon significantly outperforms known solid-state phase change refrigeration materials, especially in high-temperature environments [1]. Group 2: Implications and Applications - The "Pressure Lock Effect" refers to the phase change of certain solid materials under external pressure changes, leading to heat absorption or release, while the "Dissolution Pressure Lock Effect" extends this to dissolution heat, utilizing the fluidity of solutions for efficient heat transfer [2]. - The research team has designed an efficient four-step cycle system: pressurization and heating, heat dissipation to the environment, depressurization and cooling, and cold transport, achieving a heat absorption of 67 joules per gram of solution per cycle, with a theoretical efficiency of 77% [2]. - This new refrigeration principle has potential applications in industrial cooling systems, data center heat dissipation, and specialized refrigeration equipment [2].
