Measured and Predicted Thermodynamic Properties of Selected Halon Alternative/Nitrogen Mixtures

Abstract Experimental measurements of selected thermodynamic properties of alternative agent/nitrogen mixtures were performed. The selected alternatives were HFC-227ea (C 3 HF 7 ), CF 3 I, FC-218 (C 3 F 8 ), and HFC-125 (C 2 HF 5 ); CF 3 Br was also included as a reference. A thermodynamic model based on an extended corresponding states principle was used. The model predictions were generally found to be within 10% or less of the experimental measurements. The model can be used as a computational tool for designers of fire extinguishers to obtain pressure-temperature relationships for selected halon alternative/nitrogen mixtures.
