Abstract: With the promotion of the “One Belt, One Road” cooperation initiative, more and more overseas projects will be designed and constructed by China’s engineering company. In the most of overseas projects fire-fighting design phase, the National Fire Protection Association (NFPA) is required to meet. In order to systematically compare the design differences between the Chinese standard and the American standard of the HFC227ea fire extinguishing system, this thesis takes the control room of the Pakistan refinery project as an example for detailed comparison and analyzes the design differences.

Key words: heptafluoropropane (HFC227ea), gaseous fire suppression, standard differences
