Re: [EnergyPlus_Support] Convergence failure


This may be the result of a mismatch in the coil sizing inputs.  Make sure that 
the coil UA and water flow rate are consistent with the air loop flow rate and 
load.  

Note that COIL:Water:SimpleCooling will be eliminated in the next release of 
EnergyPlus, because there are some deficiencies in the model.  It is highly 
recommended that you use one of the other chilled water coil models, 
COIL:Water:DetailedFlatCooling or the new COIL:Water:Cooling.
