| description | The design and optimization of energy systems are very important today. Some of these systems use the ammonia-water mixture as working fluid, therefore, calculation of the thermodynamic properties becomes indispensable for its evaluation, design and optimization. In the present work an application has been developed in ExcelTM using Visual Basic (VBA) from a formulation based on free Gibbs Energy of Excess, in order to simulate different systems such as cooling, air conditioning, heat pumps, cogeneration and power cycles, without to acquire commercial simulators for this purpose. To validate this program, the results were compared with data obtained by the National Institute of Standards and Technology (NIST) software and experimental data reported in the literature. |

Ammonia-water mixture thermodynamic properties Gibb free energy enthalpy entropy Mezcla amoniaco-agua propiedades termodinámicas energía libre de Gibbs de exceso entalpía entropía The design and optimization of energy systems are very important today. Some of these systems use the ammonia-water mixture as working fluid, therefore, calculation of the thermodynamic properties becomes indispensable for its evaluation, design and optimization. In the present work an application has been developed in ExcelTM using Visual Basic (VBA) from a formulation based on free Gibbs Energy of Excess, in order to simulate different systems such as cooling, air conditioning, heat pumps, cogeneration and power cycles, without to acquire commercial simulators for this purpose.

El diseño y la optimización de sistemas energéticos en la actualidad son de gran importancia. Algunos de estos sistemas emplean la mezcla amoniaco-agua como fluido de trabajo, por lo tanto, el cálculo de las propiedades termodinámicas se vuelve indispensable para su evaluación, diseño y optimización. En el presente trabajo se ha desarrollado una aplicación en ExcelTM empleando Visual Basic (VBA) a partir de una formulación basada en la energía de Gibbs de exceso, con la finalidad de simular diversos sistemas, como pueden ser de refrigeración, aire acondicionado, bombas de calor, cogeneración y ciclos de potencia, sin la necesidad de adquirir simuladores comerciales para tal propósito. Para validar dicho programa se han comparado los resultados con los datos arrojados por el software desarrollado por el National Institute of Standars and Technology (NIST) y datos experimentales reportados en literatura.
