[Equest-users] Well water heat pump system

[Pasha Korber-Gonzalez]

Hi Bassam,

You're best bet to properly understanding how to 'represent' something in
eQuest is to access the DOE-2.2 help files.

There are only two types of HP equipment options that will allow you to
connect to a geothermal heat exchanger.  You will need to select between a
water-to-water HP and a loop-to-loop HP system to figure out which one will
best represent your design case.  Be aware that there are limits to these
pieces of equipment, so you need to be aware of the difference in
your choices and document why you chose the one you do.

 This is the quickest path to accessing the helpfile info (outside of
eQuest):
C:\Documents and Settings\All Users\Documents\eQUEST 3-63 Data\Help
Once you are in this folder double click on the icon that is labled "DOE-2
Compiled HTML help file"  It has a big yellow question mark for the icon.
When you are in the help documentation look for Volume 2:  section on
Chillers---  (I've attached a .pdf copy of the loop-to-loop HP chiller,
which is what I think you will be using with your connection to an open loop
well (Lake/Well circulation loop) water system...)

Another section that I find particularly useful to understanding how DOE-2.2
is 'thinking' about the HVAC systems we can select from, you will want to
look in the same help file I've referenced, but check out Volume 3:  the
section for air-side systems.  This reference is particularly helpful when
you need to understand how the air-side systems work in DOE-2.2.

The last thing I can offer you as a new eQuest/DOE2 user is--- the system
you are trying to depict is considered 'complex' in terms of whole building
simulation programs.  You as the simulator really need to understand how
DOE-2 is thinking about your building model & system choices in order for
you to create a successful & useful energy model.  Remember this common
analogy for whole building simulations, "garbage in = garbage out."  It's
the integrity of your inputs that will produce successful results.  It is
not safe to assume that DOE2/eQuest are intuitive to your project details.

There are many talented energy modelers in this group, this is the best
resource for whole building simulation support--in my opinion.

Pasha
p.s.  You will want to move into ddedit mode when you apply these types of
'complex' systems in your model.  The wizards can't do these systems justice
in terms of the level of detail with wizard inputs.
