摘要:
CFCS(氯氟烃)及HCFCS(氢氯氟烃)正在逐步淘汰,研究制冷用替代物并安全使用已成为制冷技术发展的重要趋势。文章通过建立可燃制冷剂爆炸极限测试实验台,研究了三种阻燃工质分别与六种可燃制冷剂混合后爆炸极限的变化情况,分析了可燃制冷剂爆炸极限的影响因素,阻燃工质对单一组元可燃工质抑爆程度受阻燃工质自身物化特性、外界环境温度、遇明火火焰能量高低、盛装计量容器外形尺寸等因素的影响。主要探索了不可燃工质对爆炸极限的抑制作用,并通过建立两种临界抑制浓度估算模型,对具有阻燃作用的制冷剂与可燃制冷剂的混合工质进行了深入实验研究。结果表明:HFC类可燃制冷剂加入阻燃工质后爆炸极限范围变化明显,而HC类可燃工质变化不大;计算出不可燃组元混合工质临界抑爆浓度,计算结果与实验结果误差小于10%;研究得到具有理想阻燃作用的哈龙替代物(CF3I、R134a等),其不同程度的掺混,将使可燃制冷剂失去可燃特性。关键词:可燃制冷剂;爆炸极限;影响因素;抑制
Abstract:
The two substances of CFCS and HCFCS are being phased out, and the research on the replacement materials and their safe usage has become an important trend in the development of refrigeration technology. Through the establishment of combustible refrigerant explosion limit test bench, the paper studied the changes of the explosion limits of three kinds of flame retardants after mixing with six kinds of flammable refrigerants, analyzes the influence factors of the flammable refrigerant explosion limit, the single component of flammable refrigerants explosion affected by flame retardant medium its physicochemical properties, environmental temperature, in case of fire flame energy level measuring container size containing influence factors such as flame retardant working fluid. Focusing on the inhibition of noncombustible substances, and through the establishment of two critical inhibition concentration estimation models, it studied the mixture of refrigerant and combustible refrigerant with flame retardant. The results show that HFC flammable refrigerant after adding flame retardant explosion limit range changes obviously, and that the HC class flammable refrigerant changes little. Uncombustible mixtures of critical explosion concentration is calculated, and the error of the calculation results and experimental results are less than 10%. The research has ideal flame retardant effect of Halon alternatives (CF3I and R134a), and the different degree of mixing will make the loss of combustible flammable refrigerants.
