Este articulo presenta los resultados del estudio realizado para obtener un tratamiento teorico unificado de la humidificacion adiabatica, aplicable a sistemas de refrigeracion y acondicionamiento de aire con la cual generar una herramienta de calculo que pueda ser utilizada en terreno como parte de su diagnostico en auditorias energeticas de este tipo de sistemas. Para lograr esto se realizan una serie de ensayos y analisis de tipo experimental en dos diferentes clases de equipo. El modelo computacional permite predecir la efectividad del sistema y principales variables de salida como la temperatura y contenido de humedad mediante la medicion de las condiciones de entrada de temperatura y flujos masicos de los fluidos que intervienen en la transferencia de masa y energia. La clave en el analisis es la definicion del coeficiente global de transferencia de calor AU, considerando la influencia de los flujos de agua y aire en el sistema. Se describe un ejemplo de validacion del modelo por cada tipo de sistema seleccionado en este estudio.
This article presents the results of the study performed to obtain a theoretical unified treatment of adiabatic humidification to be applied in refrigeration and air conditioning systems that can be used as a calculate tool in field as a part of diagnosis in audit processes of this kind of systems. To achieve this, a series of tests and experimental analysis are performed on two types of systems. The computational model is able to predict the effectiveness of the system and the main variables at the system exhaust as temperature and humidity by using the measurement of temperature and mass flow rates that participle in the energy and mass and transfer. The key in the analysis is the global heat transfer coefficient AU, considering the influence of the water an air mass flow rates in the system. An example of each system considered in this study is shown, illustrating the validation of the model.
