几种环保制冷剂爆炸极限实验研究与估算

Study of explosion limits of some alternative refrigerants

通过实验研究提供了 R1 2 5与 6种 HFC、HC制冷剂混合物的爆炸极限变化曲线图 .建立了混合工质爆炸极限与临界抑爆浓度的计算模型 ;与爆炸极限曲线图相结合 ,对含有不可燃组元混合工质的爆炸极限进行较为准确的估算 .

Flammability behaviors of refrigerants of the mixture of R125 and other 6 kinds of refrigerants of HFC and HC have been obtained through the theoretical and the experimental researches. The calculating model has been established. The results of the theoretical and the experimental researches have been shown. The paper can make the estimation for the explosion limit of the mixture including the nonflammable compound.
