许多标准、规范对使用可燃制冷剂的空调设备都有一系列的安全和技术要求,对危险性进行科学、准确、可靠的评估非常重要。本文对所有可能引起着火危险的因素进行了研究,这些因素包括:制冷剂质量、房间尺寸、典型火源、制冷剂系统的泄漏、失效的空调元件、建筑物的换气率、可燃浓度以及设备的检修,最后得出了危险性评估方案。通过采用故障树形图分析法,建立危险模型,以确定分体式空调系统出现泄漏后,上述因素对着火危险的影响程度。
Many standards and specifications have a series of safety and technical requirements for air-conditioning equipment that use flammable refrigerants. It is important that the risk is scientifically, accurately and reliably evaluated. This article examines all possible causes of fire hazards, including: refrigerant quality, room size, typical sources of ignition, refrigerant system leaks, failed air conditioning components, building ventilation, flammable concentrations, and equipment Overhaul, finally reached the risk assessment program. Through the use of fault tree analysis, a risk model is established to determine the extent of the above-mentioned impact on fire risk after a leak in a split-type air-conditioning system.
