新型制冷剂的研究现状及应用前景

PRESENT RESEARCH STATUS AND APPLICATION PROSPECTIVE OF LATE-MODEL REFRIGERANTS

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。

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 commonly used refrigerants, we point out that, in the course of substituting old refrigerants with new ones, China should utilize suitable transitional working fluids and encourage the research and development of late-model refrigerants applicable to us. The developmental direction of late-model refrigerants will be close-natural working fluids and use natural working fluids directly.
