I am having an issue with my model where I have unexpectedly high fan energy use and when I trend the aforementioned point along with the supply and return fan power, the total system/zone fan kW is much greater than the sum of the supply and return fan kW. In some cases 10 times greater. I’m using PVAV system type with enthalpy wheels. I’ve zeroed out the dP across the wheel because I have a given fan capacity. No fan-powered boxes in the zones. No exhaust fans in the zones. I’m stuck trying to determine where the extra fan energy is coming from.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any help would be greatly appreciated.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Joe<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><b><span style='font-size:12.0pt;color:#0066CC'>Joe Bliss<o:p></o:p></span></b></p><p class=MsoNormal><span style='color:#0066CC'>Designer<o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:12.0pt;color:#0066CC'>B2Q Associates, Inc.<o:p></o:p></span></b></p><p class=MsoNormal><span style='color:#0066CC'>146 Main Street #2<o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'>North Andover, MA 01845<o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'>Office: 978.208.0609 x210<o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'>Mobile: 774.277.0662<o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'>Fax: 978.719.6339<o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'><a href="http://www.b2qassociates.com/"><span style='color:blue'>www.b2qassociates.com</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='color:#0066CC'><o:p> </o:p></span></p><p class=MsoNormal>The contents of this e-mail and any attachments are confidential and the property of the B2Q Associates, Inc.
