What we are doing essentially is build a model that works like the windturbine model in TRNSYS. We take experimental data from a plant we have at the university and we correlate consumed power with produced water (we can also predict the salinity, but what is important for us is for the water to be potable according to the World Health Organization). We have opted for this approach since different approaches in the design of the reverse osmosis plant change the performance considerably. The key component is what kind of energy recovery device the plant uses as well as the sizing of the various components.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Of course if you operate the unit at nominal power steadily you can just model it using a couple of simple equations.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>You can see our work in the below published paper in Applied Energy journal.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="http://www.sciencedirect.com/science/article/pii/S0306261911003333">http://www.sciencedirect.com/science/article/pii/S0306261911003333</a><o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>In the references of this paper you can also find our previous work on the experimental investigation of the plant that we have at the university if you want to model that unit.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>-------------------------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>George Kyriakarakos, Agricultural Engineer<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>MSc Energy Systems & Renewable Energy Sources<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Agricultural University of Athens,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Dept. of Natural Resources and Agricultural Engineering<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Iera odos street, 75, Athens 11855, Greece<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Tel. +30.210.5294046 (direct), Fax: +30.210.5294023<o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Mobile +30.6942.046895<o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>e-mail: <<a href="mailto:gk@aua.gr"><span style='color:blue'>gk@aua.gr</span></a>><o:p></o:p></span></p><p class=MsoNormal><span lang=DE style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>--------------------------------------------------------------------<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> trnsys-users-bounces@cae.wisc.edu [mailto:trnsys-users-bounces@cae.wisc.edu] <b>On Behalf Of </b>Yeo Yong Hui<br><b>Sent:</b> Saturday, September 24, 2011 10:01 PM<br><b>To:</b> trnsys-users@cae.wisc.edu<br><b>Subject:</b> [TRNSYS-users] Simple Model of Reverse Osmosis Desalination Plant<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:black'>Hi, I am a student working on a project on quad-generation.
