<p class="MsoNormal">I am trying to use Trane Trace 700 to calculate my room airflows and system airflows & load requirements for the room air balance diagram show in the snip it below, also attached.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have set up a Trace model with the 3 spaces shown (CIRCULATION 196, ANTE ROOM 115, & CONTAINMENT SUITE 116). I have input information for exterior walls, windows, doors, lighting loads, & miscellaneous loads. I want Trace to do the
usual load calculation for these spaces but also include the transfer air requirements. I’m having trouble getting the transfer air to be included in the room and system level airflow calculations. See snip it below & attached for my inputs in the Create
Rooms – Airflow Tab for each of the 3 spaces mentioned.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The resulting System & Room Checksums are attached. The transfer air is not being calculated correctly. CONTAINMENT SUITE is negative but not by 100 CFM as it should be. CIRCULATION supply air and return air are equal which is also incorrect,
100 CFM of the supply air (which is greater than the 89 CFM calculated, I’ll have to artificial bump this up to at least 100 CFM) should be couted as transfer air to CONTAINMENT SUITE, therefore there shouldn’t be any return air for this space.<o:p></o:p></p>
