I guess I stumped everyone.  :)

Subject: [Equest-users] Water Source Heat Pumps as Dedicated Outside Air Units

Hello All!

I am having an issue regarding a dedicated outside air unit that takes advantage of a condensing water loop.

When modeled as a water source heat pump (TYPE = HP), eQUEST gives me an error saying this system type is not eligible for "OA-FROM-SYSTEM".

One of my thoughts is to

*         model all the units served by the outside air unit with no fresh air

*         model the dummy zone with a summation of the fresh air required by the spaces served

But then that might interfere with a proper simulation of mixed air temps going into the space.

Thoughts?
