[EnergyPlus_Support] about the chiller models in DOE-2.1E and EnergyPlus

["beyangj" <beyangj@xxxxxxxxxxx>]

Dear,
I built a model with DOE-2.1E before, and I built the model again 
with EnergyPlus, and all the condtions are the same. I found that 
the electricity consumption of the centrifugal water-cooled chiller 
in the DOE-2.1E model and in the EnergyPlus model is almost the 
same. When the centrifugal chiller was substituted by reciprocating 
chiller in both DOE-2.1 model and EnergyPlus model, I found that the 
electricity consumption were greatly different. The reciprocating 
chiller in Energyplus model consumed much more energy. When I set 
the chiller as air-cooled centrifugal chiller, the same thing 
happened. The air-cooled chiller in the EnergyPlus model consumed 
much more energy. Why these happened? I wondered whether the chiller 
models in DOE-2.1E and EnergyPlus are the same. 
The chiller models in the EnergyPlus model are set as 
Chiller:Electric:EIR, and all the coefficients are set as that in 
PerfCurves.idf in DataSets folder. Thanks in advance!

Best,

Steawart
