可燃性制冷剂的制冷空调产品生产过程安全防护策略

Safety Protection Strategy in Production Process of Refrigeration and Air-conditioning Products with Flammable Refrigerants

R32、R290以及HFOs等可燃性制冷剂被行业作为主要替代物,为制冷空调产品生产过程增加了风险,进而影响正常的安全生产秩序。本文分析了使用可燃性制冷剂制冷空调生产过程的技术特点和实际应用场景所面临的安全风险,提出了相应的安全防护策略和实施方案:需根据生产装配过程中不同区域制冷剂泄漏带来安全风险的高低,针对性地采取不同的安全防护策略;可以通过防泄漏设计、点火源识别和防护、主动安全防御措施、安全警示标志以及安全操作规程等多个方面来进行安全防护。

R32,R290 and some HFOs refrigerants have been used as the main alternative refrigerants for refrigeration and air-conditioning(R&AC)products.Due to the flammability of the refrigerants mentioned above,the production process of R&AC products has increased the risk,thereby affecting the normal order production safety.This paper analyzes in detail the technical characteristics of the production process and the safety risks in the actual application scenarios after using flammable refrigerants,and puts forward the corresponding safety protection strategies and implementation plans.Different safety protection strategies should be adopted according to the safety risks caused by refrigerant leakage in different areas during the production and assembly process.The safety protection can be carried out through many aspects such as leakage prevention design,ignition source identification and protection,active safety defense measures,safety warning signs and safety operating procedures.
