Re: [EnergyPlus_Support] Re: the condenser fan energy for air-cooled chiller
Add these report variables to your input file (IDF file) to see their
values:
Chiller Electric Consumption
Tower Fan Electric Consumption
example:
Report Variable,
*, !- Key_Value
Chiller Electric Consumption, !- Variable_Name
timestep; !- Reporting_Frequency
Report Variable,
*, !- Key_Value
Tower Fan Electric Consumption, !- Variable_Name
timestep; !- Reporting_Frequency
See Report Variables on pg. 926 of the IO Reference Manual for further
details.
These outputs are already included on the meters Electricity:Plant and
Cooling:Electricity.
See Report Meter on pg. 928 of the IO Reference Manual for further details.
