[Bldg-sim] ERV in eQUEST

[Paul Lincicome]

We're trying to evaluate the savings associated with installing sensible
energy recovery to a building. On the larger AHU's when I choose the ERV type
as sensible, it prompts a message that says, "Maximum number of tracked
modifications exceeded." I attached a screen shot of the message. eQUEST
continues to say the ERV is installed, but the actual energy consumption goes
up with the ERV's installed. Also, when I simulate the building, I get this
warning for all 7 AHU's: 

 
**WARNING********************************************************************
**

             Energy-recovery ventilator: AHU-3                            has

             condensation on the OA outlet.  First occurrence:  6 30 22

             OA T&W:  75.0  0.0172   Return T&W:  70.4  0.0099

 

Any ideas on how to rectify this would be appreciated.

Thanks,
