Re: [EnergyPlus_Support] About the condenser type of DX coil

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

I am not sure if I understand your question.  The rated capacity reported by 
EnergyPlus is at standard ARI rating conditions which are stated in the Input 
Output Reference section for the dx coil object.  If the capacity of the water 
cooled unit is reported for the same rating conditions, then the "rated" 
capacities would be the same.  I do not know for sure, but my guess is that 
water cooled dx units use a different condenser temperature as a rating point.  
The product literature for the actual equipment should be clear about the 
conditions for the rated capacity.
