[Equest-users] GSHP Loops

[Daniel Deese]

Larry,

 

            I just looked, and I don't think you can assign a pump to your ground source heat exchanger.  It may depend on the type of the heat exchanger (lake/well, vertical loop, etc.), so don't be afraid to try.  Under the heat exchanger properties, click on the "attachments" tab, and see if you can attach at pump to the loop.  The pump/s described on that tab would be the two 500 gpm pumps you describe.  You would then attach another pump to that circulation loop, and that pump would be your 1,000 gpm building circulation pump.  Technically, your two 500 gpm pumps are acting as primary pumps for your ground loop heat exchanger, and the 1,000 gpm pump is acting at the secondary pump serving the building.  If eQuest won't let you attach a primary pump to your ground loop heat exchanger, I'm stumped.  If you find out that there is a geothermal heat exchanger type that will allow you to attach a primary pump to it, please respond to the list, and all would appreciate it.  I hope this helps.  Thanks.

Hi Everybody -

 

So I've been lurking on the list for a little bit now and have a 2 questions I was hoping could be answered. First off, looking around some people say its necessary to download the GSHP curves( from 2002 located at http://www.doe2.com/download/eQUEST/) while others say its not, does anyone know the status for the latest version, 3.63b?

 

Second question, a modeling question, is in terms of our GSHP. I'm still pretty new to modeling, so if it a silly question, I apologize. I have 2 500 GPM pumps (+1 Standby) that are pulling water from our well field, and 1 more 1000gpm pump (+1Standby) pumping to the different rooms in our building. In terms of the attached image, Pump Properties, what Pump(s) is eQUEST looking for? My pumping to the Well field or to the building? Do I need to average the pumps I have?

 

Thank you in advance for your time and help.

 

Best Regards,

Larry
