Two points are important to keep in mind. First, the collector array area parameter is the area of the entire array, not just the area of one module in the array. Second, if you add a second collector you have to be careful about what you do with the flow rate. If you are adding a second collector in parallel to the first one you should double the collector array area, leave the "number in series" parameter set to 1, and double the liquid flow rate to the array. If you are adding a second collector in series with the first one, you should double the collector array area, set the number in series to 2, and leave the liquid flow rate unchanged.<o:p></o:p></p><p>kind regards,<o:p></o:p></p><p> David<o:p></o:p></p><p> <o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><div><p class=MsoNormal>On 10/20/2016 11:46, Antoine Gautier via TRNSYS-users wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif'>Hi</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;font-family:"Verdana",sans-serif'>I cannot figure out why the number of collectors in series has no effect on the collectors array efficiency: see attached project.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;font-family:"Verdana",sans-serif'>Computing equations from source code manually I would state the opposite…</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;font-family:"Verdana",sans-serif'> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:FR'>Thanks for your help.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US style='font-size:8.0pt;font-family:"Verdana",sans-serif;mso-fareast-language:FR'>Best regards</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#404040;mso-fareast-language:FR'>--</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#404040;mso-fareast-language:FR'>Antoine Gautier</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#404040;mso-fareast-language:FR'>Solamen</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#404040;mso-fareast-language:FR'>+33 6 58 24 02 60</span><o:p></o:p></p><p class=MsoNormal><span style='font-size:8.0pt;font-family:"Verdana",sans-serif;color:#404040;mso-fareast-language:FR'><a href="mailto:antoine.gautier@solamen.fr">antoine.gautier@solamen.fr</a></span><o:p></o:p></p><p class=MsoNormal> <o:p></o:p></p><p class=MsoNormal><span style='font-size:12.0pt'><br><br><br><br></span><o:p></o:p></p><pre>_______________________________________________<o:p></o:p></pre><pre>TRNSYS-users mailing list<o:p></o:p></pre><pre><a href="mailto:TRNSYS-users@lists.onebuilding.org">TRNSYS-users@lists.onebuilding.org</a><o:p></o:p></pre><pre><a href="http://lists.onebuilding.org/listinfo.cgi/trnsys-users-onebuilding.org">http://lists.onebuilding.org/listinfo.cgi/trnsys-users-onebuilding.org</a><o:p></o:p></pre></blockquote><p class=MsoNormal><span style='font-size:12.0pt'><br><br><br></span><o:p></o:p></p><pre>-- <o:p></o:p></pre><pre>***************************<o:p></o:p></pre><pre>David BRADLEY<o:p></o:p></pre><pre>Principal<o:p></o:p></pre><pre>Thermal Energy Systems Specialists, LLC<o:p></o:p></pre><pre>22 North Carroll Street - suite 370<o:p></o:p></pre><pre>Madison, WI 53703 USA<o:p></o:p></pre><pre> <o:p></o:p></pre><pre>P:+1.608.274.2577<o:p></o:p></pre><pre>F:+1.608.278.1475<o:p></o:p></pre><pre><a href="mailto:d.bradley@tess-inc.com">d.bradley@tess-inc.com</a><o:p></o:p></pre><pre> <o:p></o:p></pre><pre><a href="http://www.tess-inc.com">http://www.tess-inc.com</a><o:p></o:p></pre><pre><a href="http://www.trnsys.com">http://www.trnsys.com</a><o:p></o:p></pre></blockquote><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman",serif;mso-fareast-language:FR'><br><br><o:p></o:p></span></p><pre>-- <o:p></o:p></pre><pre>***************************<o:p></o:p></pre><pre>David BRADLEY<o:p></o:p></pre><pre>Principal<o:p></o:p></pre><pre>Thermal Energy Systems Specialists, LLC<o:p></o:p></pre><pre>22 North Carroll Street - suite 370<o:p></o:p></pre><pre>Madison, WI 53703 USA<o:p></o:p></pre><pre><o:p> </o:p></pre><pre>P:+1.608.274.2577<o:p></o:p></pre><pre>F:+1.608.278.1475<o:p></o:p></pre><pre><a href="mailto:d.bradley@tess-inc.com">d.bradley@tess-inc.com</a><o:p></o:p></pre><pre><o:p> </o:p></pre><pre><a href="http://www.tess-inc.com">http://www.tess-inc.com</a><o:p></o:p></pre><pre><a href="http://www.trnsys.com">http://www.trnsys.com</a><o:p></o:p></pre></div></body></html>
