| 摘 要： | 本文提出近自然工质的定义.发达国家环境日益恶化,美国率先研发用以替代汽车空调常用的R134a的新型制冷剂,并已在多个国家进行了替代测试实验.文章简述了一种制备此制冷剂的方法.通过对比分析几种常用汽车空调制冷剂的系统循环性能,指出在新旧制冷剂的替代过程中,我国应采用适合的过渡替代工质,并鼓励自主研发适用于我国的新型制冷剂.新型制冷剂的发展方向将是近自然工质和直接采用自然工质.

| Abstract: | In this paper,we propose a definition of close-natural working fluid.With deterioration of environment in developed countries,the United States lead is developing a late-model refrigerant as an alternative for R134a generally used in automotive air-conditioning.The relevant experiments have been carried out in a number of countries.In the paper,we outline a technique to prepare for this kind of refrigerant.Through comparison and analysis of performance in automotive air-conditioning utilizing several common... |
