<p class="MsoNormal"><span style="font-family:"Calibri",sans-serif">Hello,<br>
<br>
I have an area of 5167 Sq-Ft which I'm giving 1176 fresh air CFM. I have this modeled on HAP, Elite and Trace.<br>
<br>
HAP and Elite give me an estimated sensible load of around 35951 btu/hr and latent load of 53271 btu/hr both of which match my hand calculations perfectly. Trace, however, gives me a sensible load of around 34095 btu/hr which is okay but a latent load of 73018
 btu/hr.<br>
<br>
Why does Trace give me such a higher latent load? What am I missing?<br>
<br>
Thanks in advance. <o:p></o:p></span></p>
