Yes.  While the Engineering Reference description is somewhat brief, it 
essentially says that the general model for a heat transfer surface with 
internal source is used to model this type of heat exchanger.  The phrase "top 
surface variables correspond to `outside´ variables in standard CTF/QTF 
definition." indicates that radiant transfer with the sky is part of this  
model.
