Custom Chiller Curves

#1

Trying to define the curves of two identical chillers. Everything is fine until I plug in the Bicubic curve to the Electric Input to Cooling Output Ratio Function of Part Load Ratio Curve Name variable

Is this a bug, or am I doing something wrong? I have attached the GH file
Chillers.gh (16.2 KB)

Curve for “EItoCORFofPLR” has to be quadratic curve

Hmm. That’s interesting. I am trying to replicate the chiller curves from a chiller specified in IDF file and it is given in terms of Bicubic. Is there a chiller component that will allow me to do this?

The curve type is defined in Openstudio API.
If that is the case, you might want post a question for OpenStudio team in their github.

Ah… I was trying to replicate a REFORMULATEDEIR chiller, which does not seem to be supported by open studio yet.
