Re: [EnergyPlus_Support] A question about primary and secondary loop configuration

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

If you want to create two separate chilled water loops using COMPACT HVAC, you 
must make two different idf files, and then merge them expidf files by hand 
using a text editor.

For this particular application, it may work for you to use COMPACT HVAC to 
create a chilled water loop serving the cooling coils with variable flow 
primary and variable flow secondary.  Then, using the expidf file, add LOW TEMP 
RADIANT SYSTEM:CONSTANT FLOW to the simulation.
