Abstract:

工质在热力学循环中起着至关重要的作用。被广泛用于制冷系统及有机朗肯循环系统中的有机工质其发展现今已经进入了环保时代。有机工质环保性能中最重要的两个指标是臭氧消耗潜势(ODP)和全球变暖潜势(GWP)。而物质的辐射效率是计算GWP的一个很重要的中间参数，且其作为一个强度量，是物质固有的属性。本文从ODP和辐射效率的角度对未来环保有机工质的开发进行了一些思考，给出了未来开发环保有机工质可能会用到的基团。
Working fluid plays a very important role in thermodynamic cycle. The development of organic working fluids, which have been widely used in refrigeration systems and organic Rankine cycle, has entered an environment protection era. Ozone depletion potential (ODP) and global warming potential (GWP) are two most important indices for the evaluation of organic working fluid. Radi-ative efficiency is an intermediate parameter for GWP calculation and an inherent property of a substance as a constant value. From the perspective of ODP and radiative efficiency, this paper gives some thoughts on the future development of environment-friendly organic working fluids based on group contribution method. Groups that may be used in the future development of environment friendly organic working fluids are also given in this paper.
