摘　　要：在绿色环保替代工质的研究方面 ,由于其优越的热物性和无可比拟的环保优势 ,各类HCs物质正引起越来越多学者的注意。本文在充分论证的基础上 ,首次将HCs类工质R2 90应用于大型螺杆机组进行试验。试验结果表明 ,采用R2 90时的能效比 (EER)与R2 2时的相当 ,可见R2 90完全能够作为R2 2的直接替代工质。如果针对R2 90的可燃性对机组做少许的改动 ,则采用R2 90的大型制冷系统可望推向市场 。On the research of alternative refrigerants, because of their abvantageous thermal characters and unparalleled prepondrance of environmental protection,kinds of HCs substance have taken more and more scholars attention. At the base of full demonstration,we apply the HC s on large-scale screw-refrigerator for the first time. The result indicate that, although we do not make any better about the system,the energy-efficiency-ratio(EER) of R290 system is equally matched R22 system.So we can say that R290 can alternate R22 in the refrigeration system and can work well.If we make some improvement on the system against the flammability of HCs,then the large-scale refrigeration system with HCs as the refrigerant could march to the markets, and make immense social and economic benefits.
