IEA SHC Task 38 Solar Air Conditioning and Refrigeration Subtask C2-A, November 9, 2009 Chapter II: New developments in simulations tools and models A solar desiccant cooling installation model in SPARK, A transient detailed model of the desiccant wheel. Paul Bourdoukan LOCIE FRE CNRS 3220, Institut National de l'Energie Solaire (INES), Etienne Wurtz LOCIE FRE CNRS 3220, Institut National de l'Energie Solaire (INES), The present chapter presents a modelling approach of a solid desiccant air handling unit powered by vacuum tube solar collectors. It is divided into 3 sections. In section (1) the model of the installation is described by separately considering each component (i.e. sensible heat regenerator, desiccant wheel, evaporative coolers, solar collectors, storage tank). In the section (2) an experimental validation of the presented model is performed under different operating conditions on a component level and on a system level. Section (3) is dedicated for a transient model of the desiccant wheel. Unlike conventional models that give a mean temperature and a mean humidity ratio at the outlet of the wheel this detailed transient model gives the temperature and humidity profile at the outlet of the wheel. The model is then validated experimentally. The presented models with the experimental validation are a summary of different research work [1], [2], [3], [4] and [5] published recently and highlighted in the reference section. page 21
