<div>
<p class=MsoNormal>In ASHREA, the part load performance of chiller is described
by IPLV or NPLV.But in equest, it seems that the part load performance of
chiller is described by performance curves. How do I edit the performance
curves so that IPLV or NPLV prescribed in ASHREA are reflected in equest.<o:p></o:p></p>
