[EnergyPlus_Support] EIR Chiller Performance Curve Fitting

Dear Mike,

     I wanna simulate a electric chiller with the EIR module. And I 
found that you give a EXCEL example for the curve fitting. But I think 
the third curve in your example file may not be correct. 
     According to the input/output reference, the third curve is the 
EIR output ratio in function of Part Load Ratio. The PLR calculation in 
your file is the ratio of the available capacity to the nominal 
capacity.  In my opinion, PLR should equal to the ratio of the cooling 
load to the available capacity. Am I right?
      If I am right, could you please tell me how to obtain the third 
curve for my simulation based on the manufacturer catalog.
      Thank you in adavance
