So far the evaluation of stability regarding refrigerants has been carried out by ANSI-ASHRAE method. A metal specimen and a refrigerant are set in glass made shield tube and these are maintained statically for about 5 ~ 10 days to obtain stability results by the method. Contrary to the conventional method, in this work, a refrigerant was circulating continuously onto high dispersed type metal specimen by using closed circulating system, and as a result, the relative stability of the refrigerant having low GWP (global warming potential) like R-1234yf (2,3,3,3-tetrafluoropropylene) and R-134a (1,1,1,2-tetrafluoroethane) was obtained within several hours. It was conjectured that decomposition of R-1234yf was enhanced on nickel and aluminum metal species but was suppressed on copper metal species. In addition, the formation of hydrogen fluoride was suggested during the decomposition of R-1234yf in the presence of metals like aluminum. Thus the short term measurement for the stability of refrigerants showing low GWP was successfully achieved.

到目前为止，对制冷剂稳定性的评价主要采用ANSI-ASHRAE方法。将金属试样和制冷剂置于玻璃制屏蔽管中，静置约5 ~ 10天，以获得稳定的结果。与传统方法不同，本工作采用密闭循环系统，将制冷剂连续循环到高分散型金属试样上，得到了R-1234yf（2,3,3,3-四氟丙烯）和R-134a（1,1,1,2-四氟乙烷）等GWP值较低的制冷剂在数小时内的相对稳定性。推测R-1234yf对镍和铝金属种的分解增强，而对铜金属种的分解抑制。此外，在铝等金属存在的情况下，R-1234yf分解过程中可能会形成氟化氢。从而成功地实现了低GWP制冷剂稳定性的短期测量。
