Error in PNNL model - Full service restaurant
I used the PNNL model for Full service Restaurant (https://www.energycodes.gov/prototype...) Iam using Energyplus 9.5 and the model is reporting error like this
** Severe ** CheckAirLoopFlowBalance: AirLoopHVAC PSZ-AC_2:2 is unbalanced. Supply is > return plus outdoor air.
** ~~~ ** Environment=RUNPERIOD 1, at Simulation time=08/24 03:40 - 03:50
** ~~~ ** Flows [m3/s at standard density]: Supply=8.388132E-004 Return=0.000000 Outdoor Air=0.000000
** ~~~ ** Imbalance=8.388132E-004
No changes done on the model other than updating to the latest version How to fix this issue?? Thanks in advance.
@Adharsh which code version of 90.1 or IECC are you running? Probably doesn't matter but if you know the climate zone that would be great.
Hi Jeremy, Thanks for responding , I used 90.1. Its showing the error. Then I tried the IECC too. IECC initial run went well but its too showing error now. I am wondering weather this is an issue in the model or my energy plus???
@Adharsh - which 90.1 version of the prototypes are you using? What's the climate zone of the model you're using? The models are code version and climate zone specific. For example: are you using the 90.1-2013 models in climate zone 4C?
Hi Jeremy, ASHRAE901_RestaurantSitDown_STD2013_NewYork.idf from "https://www.energycodes.gov/prototype..." I used the above IDF. I used NewYork weather file. As I got the error, tried with other weather files too and the error is same.
