Enhancement of a Modelica Model of a Desiccant Wheel
Andreas Joos, Gerhard Schmitz, Wilson Casas · 2008
This paper presents a MODELICA model for a desiccant wheel. Desiccant wheels are used in new concepts for air conditioning systems, which can save primary energy in contrast to conventional systems. This model is based on a model, which was presented at the MODELICA Conference 2005 [2], however in this study the model is improved with a new modeling approach to represent the wheels rotation. This structural change made the model faster and able to produce continuous output in contrast to the one of Casas et al., [1, 2]. This was an essential step to enhance long term simulations of desiccant systems and control strategies. These simulations are necessary to optimize such systems and to evaluate their primary energy consumption.
