Re: [EnergyPlus_Support] Condenser outlet temperature

["Michael J. Witte" <mjwitte@xxxxxxxx>]

For air and evap cooled chillers, the condenser outlet temperature is not 
calculated.  To calculate this temperature, you would need to determine the air 
flow rate through the condenser and then use the relationship 

Qcondenser [W] = AirVolumeFlowRate [m3/s] * Density [kg/m3] * SpecificHeat 
[J/kg-K] * (Tout - Tin) [K]
