[EnergyPlus_Support] Re: the condenser fan energy for air-cooled chiller

["beyangj" <beyangj@xxxxxxxxxxx>]

Dear,
Thanks again for your reply. Now I know the condenser fan electric 
consumption is included on the meters Electricity:Plant and 
Cooling:Electricity.When I set the condenser fan power ratio greater 
than 0, I can get Chiller Electric Consumption and Chiller Cond Fan 
Electric Consumption from the report variable of Electricity:HVAC or 
Electricity:Plant. I wonder how can I get the Chiller Electric 
Consumption and Chiller Cond Fan Electric Consumption, respectively. 
How can I specify the report varibles for these two varibles in the 
item of Report MeterFileOnly in the IDF file? 

Sincerely,

Stewart
