[Equest-users] Modeling Water to Water Heat Pumps

Not sure if somebody answered this yet or not.  The short answer is no, but
hopefully

Subject: [Equest-users] Modeling Water to Water Heat Pumps

 

Hi All,

 

    We're working on a lab project that will have a 100% outside air control
strategy, and therefore significant cooling and reheat loads.  We'll be
using pretty standard chillers to provide chilled water, and rejecting the
heat to a common ground loop.  For heating, we'll be using water to water
heat pumps to remove heat from the common ground loop and put it into the
heating water loop (for pre- and re-heat).  And the third component will be
a ground loop heat exchanger (vertical wells) to act as the heat sink/source
for the heating and cooling extremes.

 

    My question really is this:  Can eQuest model a water to water heat
pump?  I found something in the DOE-2.2 volume dictionary about a
Loop-to-Loop heat pump, but it doesn't give me any .inp commands or
variables, so I'm a little scared to just throw in a loop to loop heat pump.
In addition to my fears, I don't see a "heat pump" heading under which to
put it.  

 

    If anyone has tried this before and has any insight, it would be greatly
appreciated.  thanks.
