建立了纯制冷剂气相、液相空间动态泄漏模型,详细描述动态泄漏的整个过程;分析了制冷剂主要内外因素对气相空间动态泄漏过程的影响。结果表明,同等条件下液相空间泄漏的质量泄漏速度远比气相空间的大,但后者比前者变化快;各内外因素对气相空间泄漏影响很大,其中当量泄漏半径对其影响最大。研究结果可用于评估、预测有毒有害、易燃易爆制冷剂在生产、储藏、运输过程中泄漏事故危险范围和强度。
Dynamic leakage model of pure refrigerant from vapor and liquid space was established, The whole leakage process was described in detail, And the influence of main inherent and exterior factors on dynamic leakage of vapor space was analyzed, The results showed that, On the same condition, the mass velocity of leakage from liquid space was greater than the one from vapor space, hut thc latter changed more quickly than the former. All inherent and exterior factors greatly affected vapor space leakage, in which equivalent leakage radius was the most. The results of this paper could be used to evaluate the hazardous range and intensity of leakage accident in the process of manufacturing, storing and transporting poisonous, deleterious, flammable, explosive pure refrigerants.
