Re: [EnergyPlus_Support] about the chiller coefficient

These coefficients change depending on the specific chiller specifications.  
The most accurate way to get these coefficients is to get performance data 
(capacity and power consumption) for a set of data points covering a range of 
entering chilled water and condenser water temperatures and build a spreadsheet 
to curve-fit the coefficients.  If you just want representative data, 
DataSets\PerfData.idf contains some curve data for CHILLER:ELECTRIC:EIR for 
centrifugal and reciprocating chillers.  What is the "chiller stylebook"?
