在上个世纪的大部分时间里，低温冰箱和液化器都是使用纯流体运行的。使用混合制冷剂的重要性似乎是由 Podbielniak 于 1936 年首次提出[69]，但在 Kleemenko 的开创性工作之后于 20 世纪 60 年代在大规模天然气液化中得到了实践[50]。在制冷应用中使用混合物最早是在前苏联[4, 17]。本章讨论了克服使用制冷剂混合物的纯流体运行的制冷和液化系统火用效率低的方法。
Cryogenic refrigerators and liquefiers were operated with pure fluids for much of the last century. The importance of using a mixture of refrigerants appears to have been first proposed in 1936 by Podbielniak [69], but was implemented in practice in the 1960s in large-scale natural gas liquefaction after the pioneering work of Kleemenko [50]. The use of mixtures in refrigeration applications was pioneered in the former Soviet Union [4, 17]. In this chapter, the methods for overcoming the low exergy efficiency of refrigeration and liquefaction systems operating with pure fluids using refrigerant mixtures are discussed.
