Simulación de los procesos psicrométricos

Abstract

The physical processes of water evaporation and condensation and the corresponding reverse processes, establish mechanisms of addition and/or removal of moisture, causing changes in different ecological, housing and industrial systems. Multiple air conditioning processes are needed in the industry, these have been modeled mathematically as unit operations of humidification, dehumidification and drying, in turn, they depend on several psychrometric parameters such as temperature, relative humidity, absolute humidity, pressure, etc. Its calculation by equations is more or less complex; graphic solutions are more convenient, but less precise; software and simulation packages in psychrometry are scarce. This paper develops the creation of a computerized model based on an algorithmic tool that can reduce complexity and improve the accuracy of these calculations, useful both for industrial and teaching applications. This software is based on the ®Java language to simulate cases and calculation methods of humidification, dehumidification, drying and mixtures of air based on psychrometric equations. The software can be used for a wide range of temperatures and at different altitudes above sea level. The validation of the model has been performed in Ecuador´s environmental conditions. Results showed good correlation between the results obtained via manual computation and those obtained using the model.
