[Equest-users] Fw: Heating in Summer

[Dave Weigel]

Hi Ben,

Your question intrigued me.  I have not been in great detail through your
model, but I saw right away that you have specified humidity control on your
packaged unit, with a 50 percent maximum.  I believe that your cooling
system will be running in the summer for dehumidification quite often when
the space temperature is already satisfied. The electric heat will have to
come on to re-heat the air.  This will show as a load on the heating coil.

Hope this helps! If not, I look forward to hearing what's causing your
summertime heating.

Dave

Hello Everyone!

Here's a puzzle for the email group.  (I hope you're having a better
weekend than me!)
I've searched the archived emails to find a solution, but most seem to ask
for the PD2 and INP file so that makes me think that the solutions will
mostly be unique.
I'm attaching a zip file of my model.

I have packaged single zone units with electric resistence heat.  I'm
seeing a significant load in the summer on all units.  I've dropped the
thermostat in the summer months on the heating and am still getting a
load. Any ideas on why there would be a load?

Thanks,
Ben
