<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal>I’m not sure I understand how eQuest calculates the
heating/cooling equipment loads.<o:p></o:p></p>
<p class=MsoNormal>I’ve built two models with identical envelopes and
internal loads etc, and OA supply. In model A, we have a boiler and
chiller on hot and chilled water loops and a four-pipe fan coil air-side
system. In model B, we’re using an air cooled Heat Pump and two-pipe
fan coils.<o:p></o:p></p>
<p class=MsoNormal>In report PS-C for model A, the sum heat load is -29.6 MBTU,
whereas for model B, the sum heat load is -130.2 MBTU. I understand that
the fuel use should be very different, but I don’t know why the load is
so different between the models. Shouldn’t the heating energy delivered
to the spaces be the same in both cases? Why does the Heat Pump system
have a load that is so much higher than its counterpart?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Similarly, in report SS-E, January has 110 Heating load
hours for Model A, and 385 Heating load hours for Model B. Again, shouldn’t
the loads be the same between the two models? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance for the help,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
