Abstract:

3,3,3-Trifluoropropene (HFO-1243zf) is a kind of synthetic environmentally friendly refrigerants that has applicable thermophysical property. The flammability of HFO-1243zf should be ascertained before extending its usage. The flammability limits and burning velocity of HFO-1243zf are tested as per the ASHRAE 34 and ISO— 817 standards, respectively. The tested flammability limit range is 4.45%±0.05%~15.8%±0.2% in volume fraction, which is enlarged with the increase of the environmental temperature but slightly lessened with the increase of relative humidity. The burning velocity of HFO-1243zf is increased by increasing the equivalence ratio, until which increases to a peak value and then gradually decreases on a further increase of the fuel concentration.

Key words: refrigerant, hydrofluoroolefin, R1243zf, flammability, burning velocity

摘要:

3,3,3-三氟丙烯(HFO-1243zf)是一种热物性适宜、环境友好的新一代人工合成类制冷剂。然而在规模化应用前,其基础燃爆特性必须被探明。参考ASHRE 34标准和ISO—817标准方法,分别实测了HFO-1243zf的可燃极限范围与高浓度下的燃烧速度。结果显示:HFO-1243zf的可燃极限范围为4.45%±0.05%~15.8%±0.2%(浓度),并且随环境温度的升高而扩大,随环境湿度的升高而略微缩减。HFO-1243zf的燃烧速度随等效比的增大呈先逐渐增大,在达到极大值后又逐渐减小的现象。
