[BLDG-SIM] Ground Sourced Heat Pumps

[Jarratt, David]

Thanks,
I am using eQuest 3.56, and seem to have fixed my Ground Loop Issue, my
problem appears to lie within my pump specifications within the rest of
the water-side schematic. A brief description of my system is as
follows:
- Ground Loop Heat Exchanger utilising a water loop heat pump
- 1 Heat Pump with a 2 pipe loop feeding into my heating coils and,
- 1 Heat Pump with a chilled water loop feeding into my cooling coils
 
The heating and cooling coils on my air-side schematic do reference the
correct coils and upon simulation I get the following error:
" 

***ERROR****************************************************************
*******

Loop: CHW Pump has zero design flow.

Check input for consistency, or specify design loads.

"

Once again, any help will be greatly appreciated
 
Regards,
 
David

David and all,

eQuest version 3.56 vastly improves GSHP system entry. It makes it easy
to set parameters for ground loop. It looks to me like no detailed entry
stuff is required.  BUT...for some reason, the makers have not made
version 3.56 available from the DOE2.COM web site.  Anyone know why?

We got ours by attending a training seminar.
