摘要 根据国家标准组建了爆炸极限实验装置,对实验原理及爆炸极限影响因素进行了分析,测试了作为R502替代制冷剂的HFC -161混合物及不同体积比的HFC 125 /HFC -161混合物的爆炸极限,得到了爆炸极限曲线及爆炸范围,分析了HFC- 125对HFC- 161的阻燃规律。最后根据实验数据,分析了自行开发的三元混合物HFC -161 /HFC -125 /HFC- 143a的爆炸性,得到了可安全使用的配比区。 A mixture of HFC-161 used as an alternative refrigerant to R502 is promising. It is necessary to study the flammability of HFC-161 in order to ensure the safety in application. Follow GB/T12474-90, an experimental setup for explosion limits was established. The pure HFC-161 and the mixtures of HFC-125 and HFC-161 in different ratios were tested. Basing on the experimental data, the regularity of explosion limits was analyzed with mixtures composed of HFC-125 and HFC-161 in several different ratios. The results might be used as the basis for the evaluation of the explosion limits of the new ternary mixtures of HFC-161, HFC-125 and HFC-143a.
