Subject: [EnergyPlus_Support] Model too big and too complicated? Part 2 - the E+ model
hello again,
So like I said in the other msg I just posted I think I went a bit too hard on the zoning in this model and it complicated the model down the road.
Building is 10 stories of offices with basement for just over 200 000sf. including indoor garage in bsmt.
The model has 61 zones, 1100 BuildingSurface:Detailed, 385 FenestrationSurface:Detailed, 5 main HVAC systems including Perimeter VAV, central VAV, basement (cafeteria) VAV, kitchen 100% make up air and server room LIEBERT,
There are 1 main chiller on a water tower, 1 auxiliary chiller with DX cooler, and a freecooler with water to water heat exchanger on the cooling water loop for when the weather is below 4*C.
I am considering rezoning the model in a much simpler manner now.
Zoning is:
5 zones per floor (typical) = N,S,E & W perimeter zones and a center zone.
1 extra zone for a server room on ground floor,
1 main hall
8 zones in the basement for various uses. (I should have made 3 really = garage, kitchen and cafeteria neglecting small admin offices and a mech room)
1 heated mechanical penthouse on the roof.
So the number of zones made it harder especially for the matching of inside surfaces.!! :) also, I cannot mix the central zone with more than one perimeter zone so I need to add heating when there is none.
I have had the model CRASH on me, I re-run the model after a fresh PC bootup and it went through... but with
EnergyPlus Completed Successfully-- 1387750 Warning; 0 Severe Errors; Elapsed Time=01hr 31min 28.49sec
I don't get the ===== Recurring Error Summary =====.
The temperatures, Enthalpy, Relative Humidity must be insane to get out of range. I ran many previous versions of this model without these particular errors.
I would like some clues.
The error file is posted at the end of this msg.(should I upload a file instead next time?)
Last modifications were:
- added OtherSideCoefficients and supporting scheduels for the underground surfaces (after I ran the bsmt preprocessor)
- changed a few output:variable (have 21 in total)
- changed OutputControl:Table:Style to CommaAndHTML,
- added heating to central zones with baseboards to the HVACTemplate:Zone:VAV objects
the only thing I think can do that is the OtherSideCoeficients...
(BTW I use WINMERGE free software to compare text files)
QUESTIONS:
#1 - I imagine that model computational and file "weight" is proportional to the number of surfaces and HVAC systems mainly. will it help reduce the crashing if I reduce the number of zones?
#2 - can these type of errors make the model crash in some instances but not allways if we ran the model multiple times?
#3 - I understand that recurring errors can occur at different "places" but this error file doesn't tell us much about where to look.
THANKS a lot!
