[Bldg-sim] Ground Source Water-to-Water HP in eQuest

I believe the methodology that has been implemented with success is to
use the WTW HPs with the lake well, but to use a schedule for well water
temperatures either taken from a separate run with WTA and closed loop,
or to take the temperatures from another yearly sim in either GLHE-PRO
or GS2000.

Subject: [Bldg-sim] Ground Source Water-to-Water HP in eQuest

 

This topic appears to be a gray area within eQUEST.  Has anyone been
able to successfully model a Ground Source Water-to-Water HP connected
to a closed loop Geothermal Well Field?

 

The WWHP is to serve a radiant floor.  In addition to the WWHP, the
design also has multiple Water-to-Air Heat Pumps connected to the same
well field.  Issues rise when trying to figure out how to model the
effect of the WWHP on the Well Loop.  

 

In the past I have used the Loop-to-Loop Chiller to model a WWHP, but
the chiller requires a connection to a Lake-Well type loop.  

 

Thanks in advance.
