[TRNSYS-users] Chilled Ceiling QCOMI<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>Something wrong is happening when I run my simulation with a chilled
ceiling. Until now I though the output QCOMI was the energy from the room to
the wall and it should be similar to the demand of cooling of my room. Why are
so different QCOMI and the theorical calculation:</DIV>
<DIV> </DIV>
<DIV>Energy = flow_ceiling*cp_water*(Texit_water-Tentry_water)?</DIV>
<DIV> </DIV>
