[EnergyPlus_Support] Modifying chiller performance curves EIRFPLR

[Fu Wing Yu <yufuwing@xxxxxxxxx>]

Dear E+ users

 

I would like to know how to modify the equation EIRFPLR in chiller models from the form "EIRFPLR = a + b PLR +c PLR^2" to the form "EIRFPLR = a + b PLR +c PLR^2 + d ECT + e ECT^2 + f PLRxECT" where ECT is the entering condenser temperature. The modification is required to model a variable speed chiller.

 

Any advice or suggestion is welcome!

 

Best regards

Yu Fu Wing
