[Equest-users] WSHPs in eQUEST

[Nick Caton]

Hi Ben,

 

If you want the quantity/capacities of your modeled systems to match the
scheduled equipment, you should match the actual zoning.  

 

Combining zones pretty much requires combining systems, as far as I
know... this is a by-product of the "1 system per zone" rule for DOE2.  

 

"Too large" is relative - you could explain the system is an
approximation/sum of multiple heat pumps working together... but if you
are documenting the model extensively (i.e. LEED), you may find it less
work in the long haul to invest some extra time setting up the zoning
geometries accurately to start.  That's my standard practice for heavily
documented projects.

Subject: [Equest-users] WSHPs in eQUEST

 

Greetings everyone,

I am relatively new to this list, and have been using eQUEST for only
about a year. I am modeling a 3-story office building with water-loop
heat pumps, but information from the building owner, architect, and
engineer are very limited.

 

The WSHPs are single-zone (as far as I know) and there are tons of them.
In eQUEST, do I have to create a separate zone for each one? If I make
larger zones (eg. grouping together perimeter offices), it creates heat
pumps that are too large. Is there any way to simplify the zoning and
retain the proper heat pump size and number?
