Robby,
 
I have modeled runaround loop heat recovery for unequal airflows a few
times.  Brandon Nichols has posted an explanation of how to set it up in
eQuest here:

Subject: [Bldg-sim] Heat Recovery with Runaround Loop



Has anyone had any success in predicting the energy savings for a runaround
water loop for heat recovery?  I've done some google'ing and found a couple
references to ClimateQuest's Heat Analyzer Tool, but they're all dated 2005
or earlier and ClimateQuest doesn't seem to be around anymore.

 

Does anyone have any tips or tools for analyzing this measure?  As far as I
know eQUEST is not capable of this because I'm recovering heat between two
separate airflows that are unequally sized.

 

Any help would be appreciated.

 

Thanks,
