| Abstract: | The impact of the uncertainties in the P-T equation of state and the mixing rules on the calculations of the thermodynamic property and the air-conditioning cycle performance of the HC/Fire-suppressant mixtures was analyzed. It was found that the cycle performances were not as sensitive as the VLE properties to the uncertainties in the binary interaction coefficients. The performances of HCFC22 and HC/Fire-suppressant mixtures in the air-conditioning cycles of different condensing temperatures were then comparatively assessed, which shown that the relative order in performances of different substances didn't change with the condensing temperatures. |
