摘要
吸收式制冷机诞生至今已有一百多年的时间了，在这一百多年中，吸收式制冷技术获得了长足的进步和发展。与此同时，吸收式制冷机制冷工质的选择及改善作为吸收式制冷技术的核心组成部分也得到了不断的完善和发展。吸收制冷工质对选择的每一次突破，都对吸收式制冷技术的进步产生了巨大的推动作用。本文简要回顾了吸收式制冷工质的发展过程，分析比较了当今正在研究或使用的主要工质对，同时也介绍了我们浙江大学制冷与低温工程研究所正在研究的Ｒ２２／ＤＭＦ（二甲基甲酰胺）和Ｒ２２＋Ｒ１４２ｂ／ＤＭＦ工质对的有关情况。
It has been more than one hundred years since the naissance of the first absorption refrigeration machine. The level of the absorption refrigerating technology has been greatly elevated during this period of time. The selection of the working pair,being the core technology of the absorption refrigeration, has also been perfected remarkably. Any progress made in this field has been leading to the prominent improvement of the absorption refrigerating technology. In this paper, the evolution of the working pair was briefly reviewed, and the state of the art of the current research work, including the results of our recent research work on the absorption refrigeration employing R22/DMF and R22+R142b/DMF as working pair, was presented.
