<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman,new york,times,serif;font-size:10pt;color:#000000;">Morning:<br><br>I am trying to model a chilled beam system as induction units. The primary air is supplied by an ERU. I set the outside air to 0 on the chilled beams HVAC systems tab.<br><br>In the chilled beam zone tab I set the outside air to the primary CFM and the overall CFM to the induced air flow.<br><br>Per the eQuest help menu, "The sum of the OA requirements for all SYSTEMs that reference an OA-FROM-SYSTEM
is used to set the referenced OA-FROM-SYSTEM value for MIN-OUTSIDE-AIR,
SUPPLY-FLOW as well as adjust the referenced OA-FROM-SYSTEM directly served ZONE
maximum and minimum flows for both heating and cooling." <br><br>But per my hourly reports, the ERU is not supplying the necessary amount of primary air and in the summer the ERU flow drops to .01 CFM.<br><br>Attached are the project files. Any ideas?<br><br>Thank you,<br><div> </div>Paul Diglio, CEM, CBCP<br><br><div>87 Fairmont Avenue<br>New Haven, CT 06513<br>203-415-0082</div><br><br><div><span><a target="_blank" href="http://www.pdigliollc.com">www.pdigliollc.com</a></span><div><br></div></div>
