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



Jiann C. Yang, I Vazquez, C I. Boyer, Marcia L. Huber, L A. Weber


Experimental measurements of selected thermodynamic properties of alternative agent/nitrogen mixtures were performed. The selected alternatives were HFC-227 ea (C3HF7), CF3I, FC-218 (C3F8), and HFC-125 (C2HF5); CF3Br 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.
