摘要

HFO-1243zf（R1243zf）是一种具有良好发展潜力的新一代低环境影响性制冷工质。R1243zf的安全性分类为A2，其可燃问题不容忽视。参考ASHRAE 34-2019标准方法，本文以12 L球形玻璃烧瓶为反应容器，实验测得了三种混合制冷剂R1243zf/R134a/R227ea、R1243zf/R125/R227ea和R1243zf/R125/R134a的临界可燃极限值，体积分数分别为10.82%~11.12%、10.49%~10.80%、10.89%~11.11%。进一步基于混合制冷剂可燃性估算理论得到上述混合物的临界抑爆浓度和临界可燃极限值，与实测结果相比，相对平均偏差分别为3.45%和1.68%。最后从化学抑制机理等角度对阻燃效果发生变化的原因进行了分析。

Abstract

HFO-1243zf (R1243zf) is a refrigerant with a low global warming effect and high development potential. The safety classification of R1243zf is A2; therefore

its flammability cannot be ignored. The critical flammability limits of R1243zf/R134a/R227ea

R1243zf/R125/R227ea

and R1243zf/R125/R134a were 10.82%–11.12%

10.49%–10.80%

and 10.89%–11.11% (by volume percentage)

respectively

which were determined using a 12 L glass flask reaction vessel

according to an experimental method described in ASHRAE 34-2019. Furthermore

both the critical suppression concentrations and critical flammability limits were calculated using a related estimation method for flammable refrigerant blends. Compared with the test results

the relative mean deviations were 3.45% and 1.68%

respectively. Finally

reasons for deviations in the retardant effect were analyzed based on the chemical inhibition mechanism.
