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




Check manufacturers product catalog data for specific chiller 
information. The condenser fan power ratio (Fan Power [W] / Nominal 
Capacity [W]) varies among different chiller types, chiller sizes, and 
fan selection.  Use 0.01 to get you started.
