碳氢制冷剂应用的可行性分析
Feasibility analysis about application of hydrocarbon refrigerants
摘要：
介绍了国内外碳氢制冷剂的应用情况，分析了碳氢制冷剂的危险性及碳氢制冷剂爆炸极限的影响因素。通过实验验证了碳氢制冷剂的爆炸极限，并对含有阻燃组元的碳氢可燃混合物的爆炸极限进行了研究。同时，展望了碳氢制冷剂在汽车空调中的应用前景，认为其有可能成为R12的直接充注替代物。

Abstract：
Presents the application of hydrocarbon refrigerants at home and abroad. Analyses the risk of them and discusses the influencing factors about the explosion limit. Validates the explosion limit and observes the explosion limit of flammable hydrocarbon mixtures with fire retardant components by experiment. Prospects the application of hydrocarbon refrigerants to automobile airconditioners and considers that they may be a dropin substitute for R12.
