[EnergyPlus_Support] Water Cooled Chiller EIRfPLR Curves from Data

["Jean Marais jeannieboef@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hi Guys,

It's been a while but I'm setting up Chiller Curves again. I've run up against this issue before, but I wanted to ask here:

The Datasheet Performance Data does not always have data at low Part Loads.

My method has been to look at the data and choose points at various Part Loads like (see image below) based around my rating point capacity.

This only gets me so far. Performance points that would mean a below 50% Load coverage don't exist in the data set. How do you guys make up the rest. I think we should have data to at least 25 if not 20 % of rated full load, right?

Any thoughts?

Jean
