中国研究人员发现了一种新的冷却效应,即溶解巴洛卡洛效应,在硫氰酸铵盐溶液中,在室温20秒内,温度下降近30摄氏度。 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. 当压力释放时,盐会迅速溶解,吸收热量并冷却环境。 When pressure is released, the salt rapidly dissolves, absorbing heat and cooling the environment. 这一基于流体的系统将制冷剂和热传输结合到一个介质中,提供高效率、强大的冷却能力和低排放。 This fluid-based system combines refrigerant and heat transfer in one medium, offering high efficiency, strong cooling capacity, and low emissions. 提议的四步周期实现了每克热吸收67焦耳,在模拟中达到高达77%的能源效率。 A proposed four-step cycle achieved 67 joules of heat absorption per gram and up to 77% energy efficiency in simulations. 这一突破可以帮助满足不断增加的全球冷却需求,到2050年,全球冷却需求可能超过三倍以上,并减少数据中心等能源密集型应用的排放量。 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. 研究结果发表在《自然》上。 The findings were published in Nature.
