本文围绕可燃性纯质以及混合工质制冷剂的爆炸极限问题，提出了一种新的推算常温常压下可燃性制冷剂爆炸极限浓度的理论方法。在理论分析的基础上，通过合理设计，建立了一个精度较高的爆炸极限测试系统。通过对一系列可燃性制冷剂爆炸极限的测定，表明爆炸极限对于保证可燃性冷剂在生产和储存过程中的安全方面的重要性
Concentrating on the explosion limits of flammablepure and mixed refrigerants, a new theoretical methodof calculating explosion limits under normal temperature and pressure wasestablished. By established an experimental system with high accuracy basedon theoretical analysis and designing the safety explosion vessel,the explosion limits of a series of flammable pure and mixed refrigerantswere measured. The results shows the importance of explosion limits to thesafety in manufacture and storing of flammable refrigerants
