[Bldg-sim] Equest - Space Cooling Provided by Natural Gas!?

[Aulbach, John]

Possible answer.
 
Your Flr 1 East VAV has a Solid Desiccant System attached to it, the
only system which does. As I perceive it, Desiccant is a
dehumidification device, which eQuest MAY interpret as cooling. You
attach it to a hot water loop to recharge the desiccant, so gas is used
for a "cooling" purpose.
 
See how that flies in Sioux City.

Would you mind sending me your eQuest .PD2 and .INP file? It's hard to
guess over the airwaves.

I specified only an electric screw chiller.  There is no "Engine Driven"
chiller or any piece of equipment that provides cooling which consumes
Natural Gas.

Somehow, you seem to have a chiller/heater specified. Are you SURE you
specified an electric chiller (you said CENTRAL chiller)?

I am modeling a New Orleans High School with a VAV system with Electric
Heat.  The packaged rooftop units have Heating Hot Water Coils served by
a Center Boiler and Chilled Water Coils served by a Central Chiller.  

 

For some strange reason, my summer and spring months have some space
cooling provided by Natural Gas Consumption.  Since the boiler is the
only equipment consuming Natural Gas, how is the boiler providing
cooling?  Very odd.
