[bldg-sim] ground loop heat exchanger in eQUEST

[Alpana Jain]

Hi, 

 

I am trying to model a Ground loop heat exchanger using eQUEST.
Obviously, I am going wrong somewhere, because the energy use in the
building is going up by almost 20kbtu/sqft/yr as against a variable
volume system, which in reality should actually go down.

I am modeling the GLHX along with a fluid cooler. I notice that the vent
fan energy and cooling energy go up drastically although heating energy
is reduced to almost nil.

Has anyone any experience with modeling a ground source heat pump in
eQUEST? And can tell me where I might be going wrong?

 

Thanks

 

Regards

Alpana
