[Bldg-sim] Controlling heating with outdoor temperature

[Katherine Louman-Gardiner]

Hi All,

My boss wants me to model a large AHU as a space by itself.  Our client
is running the heating loop at night (when it's below 40F), despite the
fans being off.  There is also a very leaky damper allowing fresh air in
to the space.  (I've got no cooling, and a fan mimicking the leaky
damper).  It's a wasteful practice, but we're trying to quantify How
wasteful it is.

 

My question is:

Is there a way to have the heating turn on/off based on an outdoor
temperature?

 

Since I couldn't find a way, I created a dummy zone with only
ventilation and no heating - but I still couldn't figure out a way to
use the temperature in the dummy zone to control the main zone.  The
only way I could think of was  Pkgd Single Zone, but that added cooling
and a condenser that I couldn't get rid of.

 

Anyway, Thanks for the help.  If I'm going about this the wrong way, I'd
appreciate any feedback.

 

Thank you.
