i try to figure out how Energyplus divides demand to each primary equipment (chillers, boilers, etc..) with step by step. After getting the loop demand values and available supply loop components available values ( pump flows, boller/chiller capacities and flows), how ManagePlantLoopOperation, mentioned in EP doc, choose optimal PLR and required load for each primary equipment ? Optimal PLR makes me confusing most. How i need to understand about that optimalPLR in this case ?

What it will do in simple terms:

  • Load each available equipment to the Optimum Part Load Ratio you have entered for each (if you have an availability manager that turns it off, it's not taken into account). See Chiller:Electric:EIR::OptLoad or Boiler:HotWater::OptLoad as examples
  • Distribute the remaining load accross all equipment

This happens in PlantCondLoopOperation.cc#L2205
