摘要
This invention relates to a method of converting Halon-based fire suppression systems by substituting HFC 125 for the Halon without the need for changing the in place existing distribution piping. An amount of HFC 125 greater than the amount of Halon utilized in the fire suppression system is provided, which is under a pressure to effect exhaustion of the HFC 125 of the system within a time range exceeding about 10 seconds and up to about 25 seconds and which meets the standard fire extinguishing requirements for Class A and Class B fires. An existing fire suppression system is analyzed for flow characteristics to find TD of that system. The greater quantity C+ of HFC 125 required for the retrofitted system is determined by the formulaC+=((TD−10)/(2×TCRIT)−TD×100) wherein TCRIT=0.Y×(TD−10)/(C+/100))+TD. ;The method may also be utilized to determine the amount of HFC 125 required for the retrofitted fire suppression system.
