<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

one of the topics to be discussed is VRVs.</span></font></p>

for 15 specified zones. </span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

VRV system (I do not know why they decided on this!)</span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<ol start=1 type=1>
<li class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I think I must know the performance curves of the VRV
system. However, the final choice of the VRV brand is not finalized, and I
may need to assume a typical performance curve. Any idea on which curve to
use?</span></font></li>
<li class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I have the EER of the VRV system to be 10. Where should
I enter this? Is it that I need to create a separate chiller for the VRVs
with an EER of 10?</span></font></li>
<li class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>What additional important input variables do I need
from the design team? (zone supply air flow rate, outdoor air flow rate)</span></font></li>
