CS-2009 EAp2:Minimum Energy Performance

Simulation: Baseline Chiller Part Load Performance

We are pursuing Option 1 (Whole Building Simulation). In the Proposed Case we modelled the part load performance of the chiller based on the part load performance values (fraction of Full-Load Power values) at Fan Part-Load Ratio of the manufacturer datasheet. It is unclear for me how to determine the part load performance for the Baseline Case as I could not find respective values (e.g. COP at 25/50/75%) or a graph as provided for the VAV system in G3.1.3.15. Any ideas?

Use the default curve in the software for the type of equipment you are modeling in the baseline.
