Computer Based Thermodynamic Properties of Ammonia-Water Mixture for the Analysis of Power and Refrigeration Cycles

摘要: The thermodynamic analysis and optimization of combined power refrigeration cycle as well the improved vapour absorption system necessitate development computer based properties ammonia-water mixture. In this work, a code has been developed for ammonia water mixture different pressures, temperatures mass fraction concentration. This achieved by using some exact relations co-relations available in literature. computed results have compared with published experimental data agreement is found to be good accuracy. errors are slightly more at comparatively high pressure temperature. maximum error saturated liquid entropy its value also less then 3.8% even 34.47 bar.
