<div><br></div><div>Hi Karol,</div><div><br></div><div>I have never used energy balances for zones so I don't know what Qvent, Qtrans or Qsolgain represent, but have you looked in the multizone building manual, section 5.4.1.11, page 156 : "Equal amounts of air are assumed to leave the airnode at the airnode temperature".</div>
<div><br></div><div>I don't know if it helps or not, but I think it might change your vision of how the energy balance is defined.</div><div><br></div><div>Regards,</div><div><br></div><div>Damien.</div><br><br><div class="gmail_quote">

<p class="MsoNormal"><span lang="EN-US">The balance is seems to me false because in TRNBuild in Ventilation Manager I can define only supply air ventilation. So, QVENT represents only heat from supply air, heat connect with exhaust air is probably contained in QTRANS.
