<small><font face="Arial">Hello Jaigath,<br>
Using the performance rating method (PRM), in my experience it
is usually an issue of low supply CFM.<br>
Correct me if I am wrong but on the contrary I think that ASHARE
baseline PRM fixes the cooling and heating capacities to 1.15
and 1.25 respectively and the user is allowed to bump up the
supply CFM in increments if necessary.<br>
I have a feeling that the issue of unmet load hours has been
discussed many times before -- so, the archives will be a good
resource as well.<br>

<div>Hello All,</div>
<div> </div>
<div>I would like to know how other increase their baseline
capacity when they have unmet load. I have a PSZHP system and
in one system, I got more than 400 hrs unmet load. I usually
just increase the TR cooling capacity until I get a lower
unmet load but in this case, I think the unmet load is due to
low supply cfm. Is it ok to adjust also the supply fan cfm? I
am thinking that G3.1.2.2 only requires me to adjust only the
cooling capacity. Do others adjust both cfm and cooling load?</div>

<div>Thanks,</div>
