What should be paid attention to when installing heptafluoropropane gas fire extinguishing system?

As a fire extinguishing agent, heptafluoropropane's fire extinguishing process is completed by phase change, from liquid phase to gas phase, and then decomposition. Its physical function of fire fighting is mainly to cool down. As far as chemical action is concerned, fluorine has the smallest radical radius among the active groups of halogen atoms, and its ability to capture active groups H+ and OH- in combustion is low. In addition, the generated HF is stable (which is also one of the reasons for generating a large amount of HF). Unlike HBr and HI, which have the function of re-capturing OH- active groups, they have little effect on the fracture of combustion chain. The main negative effect of heptafluoropropane is the decomposition product HF produced by chemical fire fighting. HF is toxic and corrosive under humid conditions, and reaching a certain concentration will do harm to human body and equipment. Is it also dangerous to install heptafluoropropane gas fire extinguishing system? What should be paid attention to during the installation of heptafluoropropane gas fire extinguishing system? Heptafluoropropane gas fire extinguishing system can be divided into heptafluoropropane gas fire extinguishing system with pipe network and heptafluoropropane gas fire extinguishing system without pipe network. The installation of heptafluoropropane gas fire extinguishing system without pipe network is relatively simple. Just install the cabinet type gas fire extinguishing system at the designated position, and then connect the drive line with the automatic fire alarm controller to complete the installation of the gas automatic fire extinguishing system. The field installation of heptafluoropropane gas fire extinguishing system with pipe network is more demanding than that without pipe network. The gas fire extinguishing bottle group should be located in the special bottle storage room. The bottle storage room should be close to the protected area, and should comply with the relevant provisions of the building fire resistance rating of not less than Grade II and the relevant provisions of the storage of pressure vessels, and should have direct access to the outdoor exit or evacuation walkway. The ambient temperature of bottle storage room and prefabricated fire extinguishing system protection area should be-10℃~50℃.
