[EnergyPlus_Support] Re: Heat exchanger file



Clarice, you made a mistake in the node names...

The air loop and the zone equipment loop need to be separate loops.
You are using the same node names for the inlet of the air loop and the 
outlet of the zone equipment loop.
And the same thing for the outlet of the air loop and the inlet of the 
zone equipment loop.
The same mistake is made when you define the zone equipment below.
Use unique node names for these 4 nodes.

Remember there may be other mistakes in your input, I stopped looking 
for more mistakes when I found these.
Draw a picture of you air loop and how it connects to the zone 
equipment, that ALWAYS helps.

I didn't check everything since you need to fix these before I can proceed.
