液化空气制冷刺目1974年人类采用液态氮制冷以来,英国首次发明了一种新的致冷剂,它既可用作冷却剂,又可用作生命维持剂。多年来,科学家们一直在致力于液化空气的研究,但直到现在,才解决了一些基本的技术问题,即将其合成物保存在热力状态不易稳定的储存系统内。BOC公司(
Air Liquide Cryogenic Since the introduction of liquid nitrogen refrigeration in humans in 1974, the United Kingdom has for the first time invented a new refrigerant, both as a coolant and as a life-sustaining agent. Over the years, scientists have been working on liquefied air research, but until now they have solved some of the basic technical problems of keeping their composites in a thermally unstable storage system.
