重读AHRI的《在住宅热泵系统中使用A2L级可燃制冷剂的风险评估》报告
Reinterpretation of AHRI’s Risk assessment of residential heat pump systems using A2L flammable refrigerants
摘要：
较全面、详细地介绍了AHRI的风险评估报告。该报告从CFD模拟、试验验证和故障树分析三方面评估了A2L级可燃制冷剂R32，R1234yf和R1234ze(E)用于住宅热泵系统时的风险。给出了3种制冷剂的特性参数。详细介绍了CFD模拟方案、模拟工况和模拟结果，模型验证试验的测试工况和测试结果，以及故障树分析的方法和结果。提出了2个延伸思考的问题。

Abstract：
Completely presents the AHRI’s risk assessment report. The report evaluates the risks of three A2L flammable refrigerants of R32, R1234yf and R1234ze(E) used in residential heat pump systems from the aspects of CFD simulation, testing validation and fault tree analysis. Gives the characteristic parameters of the three refrigerants. Presents the schemes, modes and results of the CFD simulation, the test conditions and results of the model test, and the schemes and results of the fault tree analysis. Puts forward two extending problems.
Keywords:A2L flammable refrigerant, heat pump, ignition risk, risk assessment, CFD simulation, fault tree analysis
