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 Card 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 Card Effect" was observed in ammonium thiocyanate solution, which exhibits significant thermal effects under pressure changes: heating occurs during pressurization, and rapid cooling occurs upon depressurization, with temperature drops of nearly 30 degrees Celsius within 20 seconds at room temperature [1][2]. - This phenomenon surpasses the performance of known solid-state phase change refrigeration materials, demonstrating a new principle for refrigeration [2]. Group 2: Engineering Applications - 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 innovative approach breaks the long-standing "low carbon - high cooling capacity - high heat transfer" triangle dilemma in the refrigeration materials field, with potential applications in industrial cooling systems, data center heat dissipation, and specialized refrigeration equipment [2].
