1. Concept and fire extinguishing principle
IG-541 fire extinguishing agent is a mixture of argon, nitrogen, carbon dioxide three gases, it naturally exists in the atmosphere, the greenhouse effect is zero, the ozone layer loss potential is zero, non-conductive, no trace after extinguishing, can be used to protect frequently occupied places. The fire extinguishing mechanism is to extinguish the fire by reducing the oxygen concentration in the protected area, and to extinguish the fire by cooling and suffocation, which is a physical way.
Hfc-propane fire extinguishing system fire extinguishing agent does not conduct electricity, does not destroy the ozone layer, no residue after extinguishing. The fire extinguishing principle is the combination of physical process and chemical reaction, and the chemical reaction can quickly eliminate the free group in the combustion process to implement the fire extinguishing, and has an efficient fire extinguishing ability.
Sevofluoropropane is superior to IG-541 gas extinguishing system in fire-fighting performance.
2, In terms of engineering cost
IG-541 gas fire extinguishing system relies on asphyxiation to extinguish fire, the design concentration is higher, the required number of storage bottles is larger, and the area is larger; And the pressure is as high as 17.2Mpa, the manufacturing and installation requirements are very strict, and the engineering cost is relatively high.
Hfc-propane fire extinguishing system is relatively expensive and needs to be replaced regularly, and the agent cost and maintenance cost are relatively large. However, due to the small amount of fire extinguishing agent and low system pressure, the equipment cost and pipe network cost are relatively low.
Summary: Heptafluoropropane fire extinguishing system has high fire extinguishing efficiency and low cost; The IG-541 gas extinguishing system is non-conductive and leaves no residue. Both fire extinguishing systems can be very efficient fire extinguishing, as for the protection area with which gas fire extinguishing system, need to be selected according to the protection area site conditions and protection objects.
