可燃制冷剂爆炸抑制模拟实验研究
Experimental study on inhibition of flammable refrigerant explosion
摘要
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 1 0%.The research has ideal flame retardant effect of Halon alternatives (CF3 I and R1 34a),and the different degree of mixing will make the loss of combustible flammable refrigerants.关键词
