<div>Cam,</div>
<div> </div>
<div>I'm curious to where you found the reference for a "single package" sub-category and how it is pointing to table A to be used for performance factors of packaged equipment as opposed to table D which is specific to packaged a/c units. </div>
<div> </div>
<div>I looked back through 90.1 and can't find any notes or guidance to follow your recommendation to point me to table 6.8.1A. Can you please provide more specific reference to where you are getting this info from Appendix G? This could be a significant thing for the rest of us to learn and for me to correct if I have missed the info you are refering to.</div>
<div> </div>
<div>Thanks for your help on this.</div>

<p class="MsoNormal">I would use 6.8.1D. Just because you are looking at a COP value doesn't mean that it wasn't originally an EER or SEER value, you might want to back out the EER value from your equivalent COP and see if you can reference it from the 6.8.1D table for Packaged equipment performance.</p>

I am looking at a model previously done by someone else and the COP has been chose as 2.96, which could mean that they have used Table 6.8.1A - Condensing units, air cooled.

<p class="MsoNormal">Hi all, </p>
<div>
<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">I am an eQuest newbie and had 2 small queries which hopefully would be answered.</p></div>
<div>
<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">01. What's the logic behind eQuest giving positive (+ve) Cooling Loads & (-ve) negative Heating Loads. (I made an Admittance Method Algorithm & it gives me the opposite values, eQuest i.e. negative cooling loads & +ve heating loads, have checked all sign convention...can't figure out why? My algorithm simulates for Delhi's (India) climate predominantly, cooling loads.</p>
</div>
<div>
<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">02. I have asked this before...is there any library for data of alternating solar gain factors, especially for Delhi, India. (As far as i believe it does'nt take into account the alternating solar gain factor...) </p>
</div>
<div>
<p class="MsoNormal"> </p></div>
<div>
<p class="MsoNormal">hope these get resolved soon, thanks in advance.</p></div>
