I added 4 additional chillers in HVAC design ( total of 5 chillers) in design-builder as shown in the figure below. image description

However, when I run the simulation in E+ and see the output file, I get 0 consumption from those additional 4 chillers ( check image below ) image description

Can anyone help me why those chillers aren't working?

Did you change the sizing fraction?

One thing to check is if all chillers have been added to the CHW plant loop at Plant Equipment Operation tab.

Tom's point is the most likely reason for only one chiller working. If you haven't already viewed them, I'd suggest you go through the free online HVAC tutorials here: https://designbuilder.co.uk/training/.... One of these covers chiller inputs. Also read the chiller information in the Program Help here: https://designbuilder.co.uk/helpv6.0/.... If you have a licence you can of course also ask our Support Desk for help here: https://support.designbuilder.co.uk/
