[Equest-users] eQuest GSHP inputs

[Todd Lagus]

Hello All,

 

I can't seem to get my space to cool using my GSHP even when I specify
sufficient cooling in terms of capacity and flow.  This is my first shot
at this type of system, so there are a lot of things that could possibly
be incorrect.  I imported coefficients from a ClimateMaster GSHP for
operating curves, but that still may be an issue.  What should the
temperature inputs be for the ground source heat exchanger loops,
specifically the HW, CHW design temperatures, and the minimum/maximum
reset and alarm temperatures.  I'm trying to model a GSHP system with 45
degree ground source water in heating and 55 degree ground source water
in cooling.  I always end up with a warning about going above the
maximum alarm temperature, and the loop shuts down.

 

Thanks in advance.
