Abstract

El subenfriamiento mecánico se emplea para incrementar el coeficiente de desempeño de cualquier ciclo de refrigeración,
especialmente en las aplicaciones de baja temperatura. Cuando es necesario reconfigurar un ciclo
existente, un dispositivo de subenfriamiento mecánico permite una gran flexibilidad para encontrar un punto
específico de operación, ya sea un sistema combinado con un mejor coeficiente de desempeño (COP) y una mayor
capacidad de refrigeración o un sistema combinado de la misma capacidad que trabaja por menos tiempo y un
mejor COP. Las simulaciones corridas en Aspen HYSYS® permiten estudiar tantos casos posibles como pueden
presentarse para lograr un diseño óptimo en el sistema reconfigurado, teniendo en cuenta la restricciones que
representan cada uno de los componentes existentes en el sistema principal.
