Re: [EnergyPlus_Support] Chiller operation

[Don Shirey <shirey@xxxxxxxxxxxx>]

Please provide more information about the input data file you are 
looking at.  If its one of the example files distributed with 
EnergyPlus, please specify which file.

Each chiller will have an output report variable for its "Chiller 
Electric Power [W]" and its "Chiller Electric Consumption [J]" (see IO 
Reference, section "Generic Chiller Outputs" and section "Report 
Variable").  You should sum the values for each chiller if you want to 
know the total electric power or electric consumption for the two 
chillers.  As an alternative, the "Chiller Electric Consumption [J]" is 
metered (i.e., summed for all electric chillers) on Electricity:Plant 
... however, this meter will also contain the pump energy and cooling 
tower fan energy if a tower is being simulated.  Look in the IO 
Reference at the section entitled "Report Meter, Report MeterFile Only" 
for more information regarding report meters.

Without knowing the specifics about the input file you are looking at, 
it is hard to answer your question about the "difference of two chillers 
and their work".  Assuming this is one of the EnergyPlus example files, 
I suspect that the file is simply showing how multiple chillers can be 
specified for a chiller plant and that their time-of-day operation can 
be scheduled by the user.
