Chiller and Boiler objects such as Chiller:Electric:EIR have a Field: Optimum Part Load Ratio. What is this for? I tried changing the ratio, but the simulation result didn't change at all, which makes sense as chiller/boiler performance is defined by performance curves. This is an unnecessary field, isn't it?
In the PlantLoop object is an input for Load Distribution Scheme.
PlantLoop,
Optimal; !- Load Distribution SchemeChoices are:
A14, \field Load Distribution Scheme
\type choice
\key Optimal
\key SequentialLoad
\key UniformLoad
\key UniformPLR
\key SequentialUniformPLR
\default SequentialLoadThis input is set up to allow a set of chillers (2 or more) to run the first few chillers at optimum part load ratio while the last chiller meets the remaining load. I have not tested this but it is supposed to work this way. I'm not sure what happens with only 1 chiller.
I see! I tested Optimal Load Distribution Scheme with 2 chillers. The chillers worked as you explained. But then, Optimal Load Distribution Scheme does not refer to performance curves. I misunderstood that. Thank you for your answer.
