This is another plant equipment operation issue I have been experiencing and was hoping someone could provide an explanation of what is going on here.
I have a pretty standard CHW loop, which has a couple of chillers and three heat exchangers. The heat exchangers go to secondary CHW loops which serve multiple buildings.
Both chillers come on and operate together to meet cooling demands. I set the "Load Distribution Scheme" to "Uniform" in OpenStudio and pressed Play. For each loop (CHW and HW) that I've set to "Uniform", I get the following error.
"
* Warning * GetPlant/CondenserLoopData: PlantLoop="CHW LOOP (SECONDARY BLDG 11 AND 12)", Invalid choice.
* ~~~ * ...Load Distribution Scheme="UNIFORM".
* ~~~ * Will default to SequentialLoad.
"
Looks like E+ is changing the Load Distribution Scheme and the behavior of the chillers looks like a sequential load scheme to me. Is this a bug? Am I doing something wrong here? Thanks! -N
