I suspect the tower is undersized. Compare the chiller condenser heat
transfer to the tower heat transfer. Then look in the eio file and see
what the autosized values are for the tower. Then manually size the
tower larger and run the simulation again.
Output:Variable,*,Chiller Cond Heat Trans Rate,hourly; !- HVAC Average [W]
Output:Variable,*,Tower Heat Transfer,hourly; !- HVAC Average [W]
