[Bldg-sim] DX Coils - Ground Loop

[Xiaobing Liu]

Andrew:
 
Could you please describe your problem more specifically? What do you mean "choose the DX Coils ground loop as my heat source"? Do you mean selecting the source for heat pump in the wizard? A reminder is, eQUEST/DOE-2.2 does not automatically size GHX and the default may be only good for light commercial building. The default GHX may be too small for large building, which will result in unrealistic high/low temperature and crash of the program.
 
Regards,
 
Xiaobing

Hey everyone.  Thank you for the help so far.  My current question is regarding the Heating via DX coils with a ground loop.  I have run every eQuest model successfully with other systems (even the other DX coil options), but every time the ground loop causes my eQuest model to crash.  Literally, the program shuts down each time I choose the DX Coils ground loop as my heat source and run the building simulation.  I would really like to see what the loads look like for this system.  Any thoughts??

 

Thanks!
