摘　　要：根据《蒙特利尔议定书》对ＣＦＣ和ＨＣＦＣ物质的禁用规定，制冷剂的替代工作在不断加速，制冷剂混合物的使用日益广泛。有些可燃性的ＨＦＣ或碳氢类化合物具有油溶性好、ＣＯＰ高等优点，因此商用的混合工质中常都至少含一种可燃组分，为此必须研究其可燃性以确保使用安全，本文介绍了可燃性实验的原理、实验台的组建和影响因素的分析，并对我们开发的二元和三元混合物如ＴＨＲ０１和ＴＨＲ０２进行了实验研究，结果表明实验具有很好的可信度，ＴＨＲ０１和ＴＨＲ０２都是不燃的。The Copenhagon revision the Montreal Protocal states that CFCs and HCFCs should be phased out. There are many alternatives , most of those are mix- tures. There are at least one flammable component in the mixtures , because the flammable refrigerants such as HFCs or hydrocarbons have good miscibility with the mineral lubricant and higher COP value , Hence the experimental investigation on flammability ought to be done , We set up an experimental instrument for flammability. The mixtures THR01 and THE02 were tested , the results showed that the data in this work are reliahle and these mixtures are nonflammable.
