制冷业或迎绿色革命 中国团队打破不可能三角关系设计四步循环

Core Insights - Chinese scientists have discovered the "dissolution pressure card effect," breaking the long-standing "low carbon - high cooling capacity - high heat transfer" triangle in refrigeration materials, potentially leading to a green revolution in the refrigeration industry [1][2]. Group 1: Breakthrough in Refrigeration Technology - The research team from the Chinese Academy of Sciences has developed solid-state phase change refrigeration materials that avoid gas refrigerant emissions, addressing climate change and energy-saving needs [1]. - The "dissolution pressure card effect" was identified in ammonium thiocyanate solution, which exhibits significant thermal effects under pressure changes, allowing for rapid temperature drops of nearly 30°C within 20 seconds at room temperature [2]. Group 2: Innovative Cooling System Design - Based on the "dissolution pressure card effect," the team designed an efficient four-step cycle system that can absorb 67 joules of heat per gram of solution, with a theoretical efficiency of 77%, showcasing excellent engineering application potential [3]. - This research lays the foundation for developing efficient, environmentally friendly, and scalable next-generation refrigeration technologies, particularly in large data center thermal management [3].
