<p class=MsoNormal>I really need some help ASAP on this.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I have a geothermal HP system and am comparing it to an
air-2-air HP system, per ASHRAE 62.1. My cooling energy usage on the
GSHP’s are significantly higher than the air-2-air HP and this despite higher
EER for the GSHP. Why is this? Is there some pumping being added
into the GSHP? It appears the pumps are separate on the Monthly Energy
Consumption report.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I am set up a DOAS and each HP receives its fresh air from
the DOAS system, yet the DOAS shows zero loads for cooling and heating in the
SS-A System Loads Summary report. This despite the warning I have in the
ATTN report that the System DOAS may have inadequate cooling capacity.
The summary report shows the full amount of CFM for the DOAS, and also shows
the capacity.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Thanks.<o:p></o:p></p>
